Temp 02 Rev1 CEPT Report XY Report B from CEPT to the European Commission in response to the Mandate “On technical conditions regarding spectrum harmonisation options for wireless radio microphones and cordless video-cameras (PMSE equipment)” Technical conditions for ensuring the sustainable operation of cordless video-cameras in the EU Report approved on DD Month YYYY by the ECC Draft CEPT REPORT 50 Page 2 1 EXECUTIVE SUMMARY This CEPT Report is the second part of the response to the Mandate issued by the European Commission on technical conditions regarding spectrum harmonisation options for wireless radio microphones and cordless video-cameras (PMSE equipment). It deals with the technical conditions for ensuring the sustainable operation of cordless video-cameras in the EU. [To be further developed] 1.1 Background PMSE use is a “contribution quality” system to enable editing and conversion into a distribution quality system. Spectrum use and its location and timing is totally dependant on “events”, which include but are not exclusive to: political,sporting, entrainment, news Contribution audio: PMSE contribution audio requires extremely low latency, below 5 ms, an interference free spectrum and high quality reproduction (which is increasing with the use of HD and HD+/UltraHD) whilst a number of companies have attempted to develop equipment using modulation schemes such as LTE. Unfortunately the time delays and lack of bandwidth have proved insurmountable. Contribution video: Video broadcast transmission now require much higher quality than analogue television, One area in which quality has expanded is that of sports were the higher definition allows the viewer to see every muscle movement, unfortunately the loss of a single frame(40 mSec) is visible to the viewer therefore as with contribution audio, interference is not acceptable for broadcast quality transmission. Different broadcast systems A major consideration when using PMSE equipment adjacent to the human body or the audience is that there are RF power restrictions in place within Europe and world wide which limit human exposure to high levels of radio frequency energy. Thus it is not possible to increase power for some applications in order to increase range or overcome interferance. Currently for major events a national administration will borrow spectrum form other users. Prime example of this are the Olympics Tour de France, Forumla 1 and Eurovision song contest. As the use of wireless broadband and similar systems expands throughout Europe it will not be possible for administrations to have the same spectrum borrowing facility that is currently in use. . [provide figures from greek and London Olympics to show growth of industrie or other major event (i.e. Tour de France increasing around 10%(mobile video links / wireless cameras) each year Arnaud)] Draft CEPT REPORT 50 Page 3 It should be born in mind that the use in adjacent bands to PMSE of aggressive modulations schemes or high power will reduce the spectrum that can successfully be used for some PMSE applications. 1.2 Recommendations One possible mitigation of this situation would be to have an electronic PMSE geo-location database and booking system for time limited spectrum use on a European basis to clearly identify spectrum available at the required location . As part of the database spectrum which could be borrowed with the clearance of the administration could also be identified Spectrum in the unpaired bands is allocated, including airborne use with PMSE as a primary user Additional spectrum in the XX and YY bands are clearly identified and PMSE as a primary user Explore use of; 2.7-2.9 GHz, especially the lower part where radars can’t be used 7110-7250 MHz Draft CEPT REPORT 50 Page 4 TABLE OF CONTENTS 1 EXECUTIVE SUMMARY ................................................................................................................................ 2 1.1 Background ....................................................................................................................................... 2 1.2 Recommendations ............................................................................................................................ 3 2 INTRODUCTION ............................................................................................................................................ 7 3 PMSE – DEFINITIONS AND GENERAL OVERVIEW ................................................................................... 8 3.1 Description of PMSE applications considered in this Report ............................................................ 9 3.2 Current usage of CORDLESS CAMERA AND VIDEO LINKS in CEPT COUNTRIES ................... 11 3.3 Technical characteristics of CORDLESS CAMERAS AND VIDEO LINKS ..................................... 12 4 TECHNICAL CHARACTERISTICS ............................................................................................................. 13 4.1 Spectrum requirements ................................................................................................................... 13 5 BAND BY BAND ASSESSMENT ON THE SUSTAINABLE OPERATION OF CORDLESS CAMERAS [AND VIDEO LINKS] ....................................................................................................................................... 15 6 SPECTRUM USE ......................................................................................................................................... 16 6.1 2 – 3 GHZ ........................................................................................................................................ 16 6.2 3-4 Ghz ............................................................................................................................................ 17 6.3 4-5GHz ............................................................................................................................................ 17 6.4 possible new spectrum .................................................................................................................... 18 6.4.1 Unpaired 2 GHz (1900 - 1920 MHZ and 2010 – 2025 MHz) ................................................. 18 6.4.2 Other spectrum ...................................................................................................................... 18 7 RESTRICTIONS ON USE OFF WIRELESS CAMERAS ............................................................................. 19 7.1 EMF ................................................................................................................................................. 19 7.2 Propagation ..................................................................................................................................... 19 7.3 Physical ........................................................................................................................................... 19 7.4 Picture quality versus bandwidth ..................................................................................................... 19 8 FUTURE STANDARDS................................................................................................................................ 20 8.1 Technological developments ........................................................................................................... 20 9 CONCLUSIONS ........................................................................................................................................... 22 ANNEX 1: MANDATE TO CEPT ON TECHNICAL CONDITIONS REGARDING SPECTRUM HARMONISATION OPTIONS FOR WIRELESS RADIO MICROPHONES AND CORDLESS VIDEOCAMERAS (PMSE EQUIPMENT) .................................................................................................................. 24 1.

It deals with the technical conditions for ensuring the sustainable operation of cordless video-cameras in the EU. This Report focuses primarily to the following task set up in the Mandate (see ANNEX 1: for the full text of the EC Mandate): (3) To identify the technical conditions and the necessary frequency bands for ensuring the sustainable operation of cordless video-cameras in the EU, including spectrum sharing opportunities possible through technological developments. Through the work related to the task (3) above, this Report also deals with the task (4) of the EC Mandate by addressing the technical conditions which can contribute to facilitate the use of cordless video-cameraequipment for EU-wide operations, including specific aspects to improve the frequency management and the overall spectrum efficiency of equipment. It addresses cordless cameras and associated video links such as those identified in Table 1. The EC mandate to CEPT on PMSE also contains other tasks dealing with wireless microphones which were addressed in the CEPT Report 50 [1]. Further information on the range of PMSE devices and spectrum use will be found in the revision of report 002. Draft CEPT REPORT 50 Page 8 3 PMSE – DEFINITIONS AND GENERAL OVERVIEW The term Programme Making1 and Special Events2 applications (PMSE) describes radio applications used for SAP/SAB, ENG/OB and applications used in meetings, conferences, cultural and education activities, trade fairs, local entertainment, sport, religious and other public or private events for perceived real-time presentation of audiovisual information. The definitions of SAP/SAB and ENG/OB are set out3 as follows: SAP: Services Ancillary to Programme making (SAP) support the activities carried out in the making of “programmes”, such as film making, advertisements, corporate videos, concerts, theatre and similar activities not initially meant for broadcasting to general public. SAB: Services Ancillary to Broadcasting (SAB) support the activities of broadcasting industry carried out in the production of their programme material. The definitions of SAP and SAB are not necessarily mutually exclusive. Therefore they are often used together as “SAP/SAB” to refer generally to the whole variety of services to transmit sound and video material over the radio links. ENG: Electronic News Gathering (ENG) is the collection of video and/or sound material by means of small, often hand-held wireless cameras and/or microphones with radio links to the news room and/or to the portable tape or other recorders. OB: Outside broadcasting (OB) is the temporary provision of programme making facilities at the location of on-going news, sport or other events, lasting from a few hours to several weeks. Mobile and/or portable radio links are required for wireless cameras or microphones at the OB location. Additionally, radio links may be required for temporary point to point connections between the OB vehicle, additional locations around it, and the studio. The definitions of ENG and OB are not mutually exclusive and certain operations could equally well reside in either or both categories. Therefore, it has been a long practice within the CEPT to consider all types of such operations under the combined term “ENG/OB”. It is also understood that ENG/OB refers to terrestrial radiocommunication services, as opposed to SNG/OB term, which refers to similar applications but over the satellite radiocommunication channels. The SAP/SAB applications include both ENG/OB and SNG/OB applications, but also the communication links that may be used in the production of programmes, such as talk-back or personal monitoring of soundtrack, telecommand, telecontrol and similar applications. Quality requirements of PMSE applications can vary depending on the task in hand. The bandwidth of the signal to be transmitted i.e. audio or video has a direct impact on the spectral bandwidth required. The perceived quality of the signals is going to be dependent on their potential final use. The uses can vary from SNG links into a news programme through to a high quality HD TV production. The reliability of service again can vary according to the task in hand. Typically within the events for large numbers of people and for broadcast applications there is frequently a need for a high degree of protection for the signals. This required protection inherently puts constraints on the amount of spectrum required to guarantee this quality of service. With regard to this CEPT Report, only PMSE applications dealing with cordless cameras and video links are considered. 1 Programme Making includes the making of a programme for broadcast, the making of a film, presentation, advertisement or audio or video recordings, and the staging or performance of an entertainment, sporting or other public event. 2 A Special Event is an occurrence of limited duration, typically between one day and a few weeks, which take place on specifically defined locations. Examples include large cultural, sport, entertainment, religious and other festivals, conferences and trade fairs. In the entertainment industry, theatrical productions may run for considerably longer. 3 For further information see the ECC Report 002 [2] Draft CEPT REPORT 50 Page 9 3.1 Description of PMSE applications considered in this Report Programme Making Special Events (PMSE) covers a wide range of equipment and applications. This Report addresses cordless cameras and associated video links. These links will often carry the associated radio microphone audio, service links and telemetry. This includes every wireless link, that contains video information, starting at a camera. In some cases all the requirements of video audio and control may be combined in a single ip link. Table 1: Definition of video SAB/SAP links Type of link Cordless cameras Portable video link Mobile airborne video link Mobile vehicular video link Temporary video links point-to-point Definitions Handheld or otherwise mounted camera with clipped on transmitter, power pack and antenna for carrying broadcast-quality video together with sound signals over short-ranges. Handheld camera with separate body-worn transmitter, power pack and antenna. Video transmission system employing radio transmitter and receivers mounted on helicopters, airships or other aircraft.(includes repeaters and relays) Video transmission system employing radio transmitter mounted in/on motorcycles, pedal cycles, cars, racing cars or boats. One or both link terminals may be used while moving. Temporary link between two points (e.g. part of a link between an OB site and a studio or network terminating point), used for carrying broadcast quality video/audio signals. Link terminals are mounted on tripods, temporary platforms, purpose built vehicles or hydraulic hoists. Twoway links are often required. From ERC Report 38: HANDBOOK ON RADIO EQUIPMENT AND SYSTEMS VIDEO LINKS FOR ENG/OB USE Draft CEPT REPORT 50 Page 10 “ Figure 1: Actual Example of ENG/OB demand for audio and service link channels cycle race Replace the picture note: need to ask SRG (Swiss broadcaster) for permission and English version of the picture [Further description and explanation perhaps with hypertext links to other parts of the document] The ERC/REC 25-10 [3] has been last revised in 2003. This document recommends CEPT Administrations to assign frequencies for audio and video SAP/SAB links on a tuning range basis. The term “tuning range” for PMSE means a range of frequencies over which radio equipment is envisaged to be capable of operating; within this tuning range, the use in any one country of radio equipment from another country will be limited to the range of frequencies identified nationally in that one country for PMSE, and will be operated in accordance with the related national conditions and requirements. Traditionally PMSE has shared with a wide range of services however recent reallocations are not able to share with PMSE and therefore these tuning ranges have become restricted or in some cases none existent. In reality tuning ranges rely on national allocations which may be a single 8 MHz channel within in that band or in worst case no available spectrum in this country. This Recommendation would need to be updated to reflect the latest developments on some of the concerned frequency bands. The following table is a subset of the Annex 2 of ERC Rec 25-10 relevant for cordless cameras and video links Table 2: Current recommended frequency ranges for use by video SAP/SAB links (subset of the Annex 2 of ERC Rec 25-10 ) Draft CEPT REPORT 50 Page 11 Type of link Cordless cameras Portable video links Mobile video links (airborne and vehicular) Temporary pointto-point video links Recommended frequencies Tuning ranges 2025-2110/2200-2500 MHz 10.0-10.60 GHz 21.2-24.5 GHz 47.2-50.2 GHz 2025-2110/2200-2500 MHz 2500-2690 MHz (Note 4) 10.0-10.60 GHz 2025-2110/2200-2500 MHz 2500-2690 MHz (Note 4) 3400-3600 MHz (Note 5) Fixed service bands (Note 6) 10.0-10.68 GHz (Note 3) 21.2-24.5 GHz Preferred sub-bands Technical parameters ERC REP 38 10.3-10.45 GHz 21.2-21.4 GHz, 22.6-23.0 GHz and 24.25-24.5 GHz ERC REP 38 10.3-10.45 GHz ERC REP 38 ERC REP 38 10.3-10.45 GHz 21.2-21.4 GHz, 22.6-23.0 GHz and 24.25-24.5 GHz Note 3: Only occasional temporary point-to-point links should be allowed in the frequency band 10.6-10.68 GHz. Studies have concluded that even limited deployment of cordless cameras and portable video links in the band 10.6-10.68 GHz will result in interference to the EESS (passive) services using this band (see ECC/REP17). Note 4: The band 2500-2690 MHz will not be available for video SAP/SAB links after the introduction of UMTS/IMT-2000 (see ECC/DEC/(02)06). Note 5: In countries where the band 3400-3600 MHz is widely used for Fixed Wireless Access (FWA), availability of this band for mobile video SAP/SAB links may be restricted. Note 6: Temporary point-to-point video links are often accommodated in the traditional fixed services’ bands, following the same channel arrangements as the FS links. 3.2 Current usage of CORDLESS CAMERA AND VIDEO LINKS in CEPT COUNTRIES During the development of this Report, the ECC developed a questionnaire to CEPT administrations on the regulatory procedures used by administrations in granting access to spectrum for PMSE [4]. It covers many frequency ranges and many PMSE usages. Put this text in a table [Bruno] Band 2025-2110 MHz (Rec 25-10): From the 32 countries providing a response on this band, 19 of them report about the availability of the band or parts of it for PMSE applications, namely temporary video links (portable, mobile with some allowance for airborne use) and cordless cameras as referred to in ERC/REC 25-10. This use is under an individual licensing regime. No change is expected for this band in relation to PMSE. Band 2200-2500 MHz (Rec 25-10): From the 32 countries providing a response on this band, 29 of them report about the availability of the band or parts of it for PMSE applications. The main type (28 countries) is related to temporary video links (portable, mobile with some allowance for airborne use) and cordless cameras as referred to in ERC/REC 25-10. In most cases, this use is under an individual licensing regime, although low power wireless cameras can in a few countries operate under a general license. It is noted that, in addition or as an alternative, 2 countries mention specifically the use of the 2400-2483.5 MHz band for wideband data transmissions or non-specific SRD as per REC 70-03 for PMSE purpose. 5 countries mentioned that current considerations on the potential introduction of Broadband Wireless systems in the band 2300-2400 MHz may have an impact on the availability of the band for PMSE. Band 2500-2690 MHz (Rec 25-10): From the 32 countries providing a response on this band, 5 of them report about the availability of the band or parts of it for PMSE application, namely SAB/SAP, video links. Amongst those, 3 countries expect that the use of PMSE will cease because of the introduction of terrestrial Electronic Communications Networks in the 2500-2690 MHz band. On this basis, the relevance of maintaining this band in the ERC/REC 25-10 may be considered. Draft CEPT REPORT 50 Page 12 Band 3400 – 3600 MHz (Rec. 25-10): From the 32 countries providing a response on this band, 9 of them report about the availability of the band or parts of it for PMSE applications, which tends to confirm a decrease of the availability of this band for PMSE. PMSE applications in this band cover temporary video links (portable, mobile with some allowance for airborne use) and cordless cameras as referred to in ERC/REC 25-10. This use is under an individual licensing regime. The development of IMT in this band may have an impact on the spectrum available for PMSE in this band. Band 4400 – 5000 MHz: From the 32 countries providing a response on this band, 7 of them report about the availability of the band or parts of it for PMSE applications. PMSE applications in this band cover SAB/SAP links for temporary use deployed in a coordinated way to protect other use (mainly military applications). This PMSE use is in most cases under an individual licensing regime. Band 10.0 – 10.68 GHz (Rec. 25-10): From the 32 countries providing a response on this band, 26 of them report about the availability of the band or parts of it for PMSE applications. The amount of available spectrum and the frequency bands within the overall tuning range vary significantly depending upon the country. The main PMSE applications covered in this range are wireless cameras, portable video links and point-to-point video links for temporary use as referred to in ERC/REC 25-10. This use is in most cases under an individual licensing regime. No major change is generally expected for this band in relation to PMSE. Band 21.20 – 24.50 GHz (Rec. 25-10): From the 32 countries providing a response on this band, 25 of them report about the availability of the band or parts of it for PMSE applications. The amount of available spectrum and the frequency bands within the overall tuning range vary significantly depending upon the country. The main PMSE applications covered in this range are wireless cameras, portable video links and point-to-point video links for temporary use as referred to in ERC/REC 25-10. This use is in most cases under an individual licensing regime. A few changes are expected, which may slightly increase the availability of spectrum for PMSE. Band 47.20 - 50.20 GHz (Rec. 25-10): From the 32 countries providing a response on this band, 16 of them report about the availability of the band or parts of it for PMSE applications. The main PMSE applications covered in this range are wireless cameras and portable video links as referred to in ERC/REC 25-10. This use is in most cases under an individual licensing regime. No change is expected with regard to PMSE in this band. Other bands: the availability of frequency bands within the 6/8 GHz range is mentioned by 8 countries for fixed and/or mobile ENG/OB. 3.3 Technical characteristics of CORDLESS CAMERAS AND VIDEO LINKS Indoor deploy.

Spectrum requirements Revision:[Vaughn] The use of cordless cameras has seen an increase over the last few years as the production values and requirements of coverage has increased. This has correspondingly led to an increase in demand for spectrum especially to support major events. Due to the range of activities that PMSE covers, from single camera news-gathering to multi-camera international sporting or cultural events, and the temporal and location specific nature it is difficult to quantify spectrum requirements. It is recognised that high demand scenarios tend to be accommodated through local solutions whereby temporary access to bands not normally allocated to PMSE is provided. Due to a number of changes to the allocation of spectrum in the 2-3 GHz range, spectrum availability is Draft CEPT REPORT 50 Page 14 becoming more limited for use by PMSE. ERC Recommendation 25-10 identifies 575 MHz of spectrum in the 2-3 GHz range for PMSE. However, recent allocations to services with which PMSE cannot share (eg. in the 2.5-2.69 GHz band and potentially within the 2.3-2.4 GHz band depending on future studies within CEPT) has resulted in a significant reduction of available spectrum for PMSE. To mitigate this loss it is important to identify and carry out compatibility studies on bands that could potentially accommodate cordless cameras. The information below show numbers of links used in various major events. The numbers show that for proper high quality productions the occupied bandwidth sums up from 162 MHz(Berlin state elections) to 680 MHz (Formula 1)These figures are without consideration of guard bands/separation distances between the applications or intermodulation effects.

The relative bandwidth and size of 2GHz antenna allow automatic or manual antenna systems of track successfully for mobile use, the higher the frequency the narrower the bandwidth of the antenna and therefore harder to successfully track when mobile. In all cases PMSE spectrum is considered as tuning ranges and therefore it appears that there is a large amount of spectrum. The term “tuning range” for PMSE means a range of frequencies over which radio equipment is envisaged to be capable of operating; within this tuning range, the use in any one country of radio equipment from another country will be limited to the range of frequencies identified nationally in that one country for PMSE, and will be operated in accordance with the related national conditions and requirements. Traditionally PMSE has shared with a wide range of services however recent reallocations are not able to share with PMSE and therefore these tuning ranges has become restricted or in some cases none existent. In reality tuning ranges rely on national allocations which may be a single 8 MHz channel within in that band or in worst case no available spectrum in this country. In the paragraphs below the current allocations from REC 25-10 are identified along with comments on where they have been impacted by other services. Frequency ranges below 5GHz are favoured for low power cordless cameras operating over short unobstructed paths, with the advantage of relatively low diffraction loss. Multiple carrier forms of digital modulation, particularly COFDM, which are rugged and perform well in the presence of multipath, have driven greater and increasing use of low power wireless cameras in recent years. Coupled below have Differentiate between wireless Cams and downlinks /airborn Wireless camera’s (using MPEG encoding) and mobile (up-)links use the digital DVB-T, ISDB-T or derivative standards such as LMS-T. Al these standards are made for main distribution terrestrial broadcasting transmitters and can work by means of reflections and diversity receive technologies. Obstructed RF paths with enough reflective surfaces can still give un-interrupted video at the receive site. Data rates are limited. (see list) The DVB-S2 standard is preliminary made for satellite links, so “line off sight” usage. The advantages are more bandwidth and higher data rates. (see list) Diversity systems by it’s nature are not available for DVBS2.Downlinks from airplanes and helicopters working “line off sight” can carry muxed DVB-S2 transport streams up to 90 Mbit. Develop a figure showing spectrum lost regarding tuning range Do the mathematics between the European Common Allocation Table from 2004 and the table from 2013? 4 Please see ECC Report 38 for further details Draft CEPT REPORT 50 Page 16 6 SPECTRUM USE Sharing spectrum between primary services and PMSE should become more efficient, simple5 and reliable. Sharing is about trust between the primary and secondary user. The only reason why secondary services require their own spectrum is that they want to be sure it’s available when it is needed and in a suitable time scale. These criteria and others could be solved by an electronic booking system which would enable the military and other primary users to pre book or exclude geographical arrears in peace time operations. Harmonization, sharing, coordination and enforcement can only be successful if the frame work is clear and standardized. We should go for a fixed raster, ETSI specified equipment on spurious, and other technical conditions. Existing spectrum allocations allow sharing with PMSE, the new services, mainly MFCN are unable to share with PMSE and in many cases require a guard band either side of the new allocation. This has two results: 1. Existing PMSE services are being forced to do their work in less spectrum 2. Due to the nature of MFCN it is not available for Administrations to loan for “major event” use Sharing possibilities between primary and secondary users should be better developed and more realistic proposals formulated Major events are currently relying on loan spectrum that will not be available to PMSE by later in 2013!! The uncertainty in instant availability of spectrum in existing PMSE tuning ranges is a major concern for the industry, this uncertainty is coupled with increasing requirement for in all aspects of content production : a review of the F1 coverage will endorse this. Replacement spectrum is urgently required and as a partial replacement of reallocatted 2GHz spectrum should be able to claim primary user status in the 1900-1920 and 2010-2025 MHz bands. Harmonised military bands: A frequency band which is in general military use in Europe and identified for military utilisation in the European Common Allocation Table (ECA Table). Such a frequency bands forms a basis for military use and planning. The band can be shared between civil and military users according to national requirements and legislation. 6.1 2 – 3 GHZ propagation / practical issues 5 One possible mitigation of this situation would be to have an electronic PMSE geo-location database and booking system for time limited spectrum use on a European basis to clearly identify spectrum available at the required location . As part of the database spectrum which could be borrowed with the clearance of the administration could also be identified Draft CEPT REPORT 50 Page 17 Frequencies in this band are mainly used for wireless camera’s, down-linking video signals from aerial relay platforms such as helicopters, planes or airships. The usage (except for the wireless camera’s) is Space to earth (air to ground) so complementary to the space operation in this band. This part of the spectrum should stay available for non LOS systems using MIMO, Diversity and reflection techniques to maintain a high throughput to regain their original signal.) Put LOS and MIMO in definitions and work with hyperlinks! Due to the altitude and coverage of these platforms a simple frequency coordination system needs to be harmonized with all CEPT administrations. Frequencies in this band are mainly used for wireless camera’s and up-linking video signals from motorcycles, cars, boats and camera helicopters. The usage (except for the wireless camera’s) is Earth to space (ground to air) so complementary to the space operation in this band. This part of the spectrum should stay available for non LOS systems using MIMO, Diversity and reflection techniques to maintain a high throughput to regain their original signal.) 6.2 3-4 Ghz propagation / practical issues 6.3 4-5GHz propagation / practical issues Draft CEPT REPORT 50 Page 18 6.4 possible new spectrum 6.4.1 Unpaired 2 GHz (1900 - 1920 MHZ and 2010 – 2025 MHz) This is ideal spectrum, most equipment will tune to it. It has similar propagation to the 2-3 GHz range.

As an example use of a 4 Watt ( +36dBm.)Transmitter in the 2 GHz. band on a bike feeding the RF into a circular antenna with a gain of 6 dB. It is requiredan to extend antenna pole by 30 cm. to stay under this limit. This combination is the maximum RF power allowable in these situation. (Any longer and the pole would hit the public when the motorbike is rounding corners.) 7.2 Propagation Nowadays major events are increasingly relying on fixed wing aircraft for relaying audio and video content. The advantage is longer endurance and less weather dependency than helicopters. Microwave systems lose some 20 dB. at 2 GHz. with an aircraft flying at 10,000 ft. compared with a relay helicopter flying at 1000 ft. Moving the uplinks to higher frequencies will greatly increase the loss for airborne use . Another downside of moving the uplinks to higher frequencies is that non LOS operations will become more difficult if not impossible in many circumstances.However LOS links could be moved to higher frequencies 7.3 Physical 7.4 For all mobile equipment the physical size and weight are critical, battery weight is a major part of this therefore RF output power is kept to a minimum.Picture quality versus bandwidth With digital systems there is a trade off between quality, latency, and bandwidth ,Dependant on spectrum availability, demand by the use, budget, a choice of quality can be made.. If we wish to harmonize and coordinate these activities in future standerisation of channel bandwidth to 10MHz should be consideredSingle standard H264 (dvb-t like) links should be able to perform well within a 10 MHz. channel. Some wireless camera’s uses Jpeg2000 compression and the 802.16 standard using scalable OFDMA to carry data, supporting channel bandwidths of between 1.25 MHz and 20 MHz, with up to 2048 subcarriers,and two or more adjcent channels would be required for the maximum data rate .. Special systems such as LMS-T (20 MHz. wide) also require two adjacent channels .Other systems require three adjacent channels . Some wireless camera’s systems need a return audio link for synchronization refered to as genlocking this will improve the latency. Downside is that when something happens with the audio link (usually in the PMRbands ) the camera will fail. Wireless camera’s also oftern use PMR frequencies for cueing the cameraman , camera control (iris, paint, black level) and tally. Draft CEPT REPORT 50 Page 20 8 FUTURE STANDARDS 8.1 Technological developments Traditionally cordless cameras used analogue modulation techniques to carry the video stream from camera to the reception point and onto the production centre. These analogue techniques typically used around 30 MHz of spectrum per camera, and provided essentially real-time delivery of the video. More recently, the use of digital modulation based on widely deployed distribution standards, such as DVB and ISDB-T, have reduced the bandwidth requirements to typically 10 MHz per camera. Although these digital standards provide modes which allow greater data compression for distribution links, these are not available for cordless camera links due to the requirements for high picture quality, low coding delay and high robustness to transmission errors. However, there is also a trend in video production embracing widescreen, high definition (HD), 3-D, and, looking forward, to ultra-high definition (UHD) and to higher frame-rates, the latter especially for sports coverage to provide smoother motion. All these trends require higher capacity links, since higher resolution and higher frame-rates both demand additional data to be coded. There are some new techniques currently in development which aim to provide higher capacity within existing channel bandwidths. The BBC's Research and Development department, which has contributed much to the current cordless camera link technology, has been developing new techniques making use of more recent modulation and coding standards, as found for instance in DVB-T2 and DVB-NGH, to allow a ‘next generation’ cordless Draft CEPT REPORT 50 Page 21 camera which would approximately double the spectrum efficiency compared to those based on the DVB-T standard. A key ingredient is the inclusion of ‘Multiple Input Multiple Output’ (MIMO) technologies in conjunction with COFDM in order to provide a foundation for the increased throughput sought. This is supported by an LDPC-based error-correction chain based on those used in DVB-T2 and DVB-NGH. The current state of development offers 40Mb/s in 10 MHz, but it is envisaged that a variant offering 30Mb/s in the same bandwidth is feasible, as well as ‘scaled’ systems providing up to 120Mb/s in 20MHz, a bit-rate intended to support lightly-compressed studio quality video. As the name implies, MIMO operation requires the use of multiple transmission and receiving antennas. The BBC technique is based on system dimension of 4x4 (i.e. four receive and four transmit antenna elements), in order to allow effective operation in environments characterised by a high degree of signal reflection and scattering (typically indoors) and those where a strong line-of-sight component is dominant (typically outdoors). Although based on a 4x4 dimension, typically two physical antennas will be used for transmission and two for reception, permitted by the use of sophisticated signal processing. Draft CEPT REPORT 50 Page 22 9 CONCLUSIONS Due to the reduction in available spectrum for the 2 to 3 GHz range additional spectrum will be urgently required to sustain current use for mobile and airborne use. The use of spectrum is limited by the application i.e. a motorcycle uplink could work at 2 GHz but not at 50 GHz. (annex with calculations) Whilst equipment has become more spectrum efficient reducing from 28MHz to 10MHz bandwidth, new higher definition systems my require simultaneous use of two or more adjacent channels Traditionally PMSE has shared with various primary services but with the new allocations to services such as wireless broadband sharing is not practical. In order to achieve spectrum efficiency and coordination where large numbers of PMSE systems are deployed consideration of the current ETSI standards for the new and existing services and their implementation into all equipment should be considered by administrations. Loss of spectrum (spreadsheet /graph) High quality, low latency, interference free. Introduction of some new services in adjacent bands can have an impact on the usable PMSE spectrum as the out of band energy limits the usable spectrum, and some primary services require guardbands . Data links? Currently a wide range of applications use PMSE as the equivalent of a pen to a writer these range from sport to advertising and court reporting through to nature recording.. The economic benefit of these activities are difficult if not impossible to define but with the creative and cultural nature expressed via PMSE use the general public has had access to pictures, recordings and information which would be unthinkable even ten years ago. If the economic and cultural benefits of this creativity are to continue sufficient spectrum needs to be available. Some administrations have placed a legal requirement on broadcasters to report on a range of subjects such as emergency communication to the public in the case of natural disasters or specific forms of accidents and news, in order to carry out these legal required functions sufficient PMSE spectrum must be available. 1900 - 1920 MHZ and 2010 – 2025 MHz are immediately available and should be allocated as soon as possible with PMSE as a primary user and include airborne use 2.700 – 2.900 MHz should be urgently investigated for PMSE use, with the minimum technical restrictions The majority be PMSE functions can be planed in advance however news and disasters, natural or man made are time critical and instantaneous in nature. In order to cope with and in many cases may involve cross border activities an electronic database booking system for CEPT countries should be considered 4400-5000 MHz should also be urgently investigated for PMSE use, with the minimum technical restrictions Draft CEPT REPORT 50 Page 23 [ . ] . Spectrum requirements are always difficult to define as they occur at geographically separated sites and different times however from the figures provided in 4.1 it would appear that a minimum of 162 MHz is required and if we consider the 10% increase year to year in the Tour de France an increase of at least 16 MHz per year needs to be added for the foreseeable future. In addition administrations should be encouraged to identify spectrum witch could be released for big events on a geographical or time limited basis within the tuning range of existing equipment Draft CEPT REPORT 50 Page 24 ANNEX 1: MANDATE TO CEPT ON TECHNICAL CONDITIONS REGARDING SPECTRUM HARMONISATION OPTIONS FOR WIRELESS RADIO MICROPHONES AND CORDLESS VIDEOCAMERAS (PMSE EQUIPMENT) EUROPEAN COMMISSION Information Society and Media Directorate-General Electronic Communications Policy Radio Spectrum Policy Brussels, 15 December 2011 DG INFSO/B4 FINAL MANDATE TO CEPT ON TECHNICAL CONDITIONS REGARDING SPECTRUM HARMONISATION OPTIONS FOR WIRELESS RADIO MICROPHONES AND CORDLESS VIDEO-CAMERAS (PMSE EQUIPMENT) 1. PURPOSE This mandate is a follow-up to the commitment made by the Commission in the Communication on the digital dividend6 and in the proposal for a Radio Spectrum Policy Programme. 7 The main objective of this mandate is to identify technical conditions and options to make EU harmonised spectrum available for wireless radio microphones and cordless video-cameras. The aim is not to satisfy all the spectrum requirements8 of the relevant users, but rather to create a baseline for economies of scale and the functioning of the internal market. Programme Making and Special Events (PMSE) applications fulfil an important role supporting social and cultural activities, ranging from local to EU-wide events and broadcasts, which also make a significant economic contribution. Various types of equipment are involved, such as wireless microphone applications, in-ear systems, cordless video-cameras and remote control systems, used in both professional and non professional environments. 6 Communication from the Commission to the European Parliament, the Council, the European Economic and Social Committee and the Committee of the Regions – Transforming the digital dividend into social benefits and economic growth /*COM/2009/0586 final*/ 7 Proposal for a Decision of the European Parliament and of the Council establishing the first radio spectrum policy programme /*COM/2010/0471 final – COD 2010/0252*/ 8 Large events may have much higher spectrum requirements. However, these are very local and may vary over time. Consequently, they are best addressed through national case by case solutions on the base of appropriate equipment standards that specify tuning ranges for equipment. Draft CEPT REPORT 50 Page 25 2. JUSTIFICATION Pursuant to Article 4 of the Radio Spectrum Decision9 the Commission may issue mandates to the CEPT for the development of technical implementing measures with a view to ensuring harmonised conditions for the availability and efficient use of radio spectrum; such mandates shall set the task to be performed and the timetable therefore. Without prejudice to the final text to be adopted by the European Parliament and the Council, the draft Radio Spectrum Policy Programme states that Member States shall examine ways and, where appropriate, take technical and regulatory measures, to ensure that the freeing of the 800 MHz band does not adversely affect PMSE users. In addition it states that Member States shall, in cooperation with the Commission, seek to ensure the necessary frequency bands for PMSE, according to the Union's objectives to improve the integration of the internal market and access to culture. CEPT Report 3210 concludes that: The historic use of PMSE of the 470-862 MHz band will need to be adapted. PMSE demand for spectrum is expected to continue to rise in the medium term. Interleaved channels/white spaces in the UHF band are the principal spectrum for wide band audio applications. Therefore, the 470 MHz to 790 MHz range should be maintained for PMSE allowing them to operate on a temporary basis in areas where broadcasting is not yet used. New frequency bands could be made available to PMSE in addition to 470-790 MHz. In order to address in particular non-professional applications and a substantial amount of professional applications, and while recognising that it is not the aim to address all spectrum requirements, there is considerable justification for harmonising the band 821-832 MHz for wireless microphones. Furthermore, the identification of detailed technical conditions for the use of band 1785-1805 MHz by wireless radio microphones is required before considering a possible harmonisation measure which includes EU-wide operations (this could include for example indoor and outdoor use and the variety of professional and non-professional situations). In addition to the audio applications (wireless microphones) there is another important category of PMSE equipment, cordless video-cameras, which may face spectrum access issues. Currently, cordless video-cameras are often operating in the 2.3 GHz band and additional in the 2.6 GHz band. The fact that the 2.6 GHz band has been harmonised for terrestrial systems providing electronic communications services under new conditions of use and that some Member States are contemplating the use of the 2.3 GHz in the same way, makes it necessary to consider an alternative and sustainable solution for spectrum access for cordless video-cameras. Therefore, options or alternatives for spectrum use by cordless video-cameras need to be developed. It would be desirable to investigate new bands for cordless video-cameras use and sharing opportunities. 9 Decision 676/2002/EC of the European Parliament and of the Council of 7 March 2002 on a regulatory framework for radio spectrum policy in the European Community, OJL 108 of 24.4.2002. 10 30 October 2009. Draft CEPT REPORT 50 Page 26 Considering the above and taking into account the fact that EU-wide operations (such as touring shows) as well as ordinary citizens using wireless microphone equipment for non-professional purposes, could both benefit from harmonisation, the Commission believes that an additional mandate is justified. The mandate should concentrate on the analysis of the 821-832 MHz and 1785-1805 MHz bands for wireless microphones and on clarifying technical options to address future needs for cordless video-cameras. 3. MAIN EU POLICY OBJECTIVES With this mandate, the Commission issues guidance to the CEPT to continue developing technical conditions and studies serving policy objectives which contributes to an improvement of efficient use of spectrum resulting in positive economic, social and cultural benefits in the EU. These main policy objectives include: 4. To ensure the availability of core spectrum for some categories of PMSE equipment, respectively wireless radio microphones and cordless video-cameras, with a view to supporting the development of media and entertainment industry (PMSE); To strengthen the Internal Market dimension for potential single market services and PMSE equipment, that can improve frequency management, in relation to PMSE use as well as to improve the spectrum efficiency of PMSE equipment. To exploit the socio-economic and cultural benefit for EU citizens and PMSE users to the fullest extent by facilitating economies of scale, lower prices and foster cross-border portability and interoperability. TASK ORDER AND SCHEDULE Through this mandate, the CEPT is requested: (1) To identify the technical conditions for the use of the band 821-832 MHz for wireless radio microphones (which optionally include in-ear systems and control systems) in the EU. This should take into account the technical conditions specified in EC Decision 2010/267/EU on the EU harmonisation of the 800 MHz band as well as any relevant outcomes of WRC-12. (2) To identify the technical conditions resulting in a harmonisation of technical parameters in the band 1785-1805 MHz for the use of wireless radio microphones (which optionally include inear systems and control systems). (3) To identify the technical conditions and the necessary frequency bands for ensuring the sustainable operation of cordless video-cameras in the EU, including spectrum sharing opportunities possible through technological developments. (4) To identify technical conditions which can contribute to facilitate the use of wireless radio microphone and cordless video-camera-equipment for EU-wide operations, including specific aspects to improve the frequency management and the overall spectrum efficiency of equipment, Draft CEPT REPORT 50 Page 27 The Commission may provide CEPT with further guidance on this mandate. The deliverable for this mandate will be two reports A and B: Report A on the technical conditions for the use of the bands 821-832 MHz and 1785-1805 MHz for wireless radio microphones in the EU, including the technical conditions which can contribute to facilitate the PMSE equipment for EU-wide operations; Report B on the technical conditions for ensuring the sustainable operation of cordless videocameras in the EU. The following delivery dates are scheduled: Delivery date Deliverable 3/07/12 For RSC#40 Progress report A 4/12/12 For RSC#42 Progress report B 4/12/12 For RSC#42 Draft final report A, subject to public consultation 11/03/13 Final report A delivery July 2013 For RSC#44 Draft final report B, subject to public consultation November 2013 Final report B delivery In implementing this mandate, the CEPT shall, where relevant, take the utmost account of Community law applicable and support the principles of technological neutrality, nondiscrimination and proportionality insofar as technically possible. The Commission, with the assistance of the Radio Spectrum Committee pursuant to the Radio Spectrum decision, may consider applying the results of this mandate in the EU, pursuant to Article 4 of the Radio Spectrum Decision. *** Draft CEPT REPORT 50 Page 28 ANNEX 2: LIST OF REFERENCES CEPT Report 50 ECC Report 02: SAP/SAB (Incl.

Now they are digital and use better modulations schemes and high compression codecs using 10 MHz. However the higher definition (HD HD+/UltraHD higher frame rate(HFR)) will require higher bandwidth. BBC paper BBC providing a section on new technics With the use of auto tracking systems which improve signal to noise ratio and quality there is often a requirement for a feedback channel which can be narrow band or broad band in order to keep the transmitter and receiver synchronised In some cases multiple audio channels are supplied inband which enable talkback from the camera operator to production crew and for the operator to receive instructions. Equipment has become miniaturized while still enabling high quality transmissions a side effect of this is to widen the use to such things as cameras and audio are being carried by referees and linesman in sporting events. The market for PMSE equipment is small compared to other radio sectors but new technologies are being developed in parallel with the security surveillance and military sectors. Mesh technologies improve the reliability of links but there is a tradeoff in complexity of cost of the systems and their deployment as well as the additional need to ensure low delay in PMSE compared to other applications. Airborne links have employed military technologies permitting dynamically steerable antennas at high altitude compared to the traditional less directional airborne antennas used at lower altitudes from helicopters. Provision of up-to-date news coverage is under great pressure of time. Therefore reporter backpacks which are sending a video stream over multiple mobile network connections is a good way for a single reporter to start streaming video footage while he is waiting for the OB team to arrive. One problems with these systems is, due to the high buffer size the delay to broadcasting station can be up to 12 seconds, which makes interviews impossible. You also have to rely on the public IMT networks and you have to share the capacity of this networks. This requires the use of scalable video codecs, adaptive streaming and buffers. This leads to the fact that when the available bandwidth drops, a decreased picture quality will be the consequence. Especially users of reporter backpacks who have to deal with disasters and/or emergencies may find that public bodies have "taken over" the mobile providers' networks. In this case the mobile data networks will not be available, or only in a very restricted way. Some program makers use WiFi on the SRD spectrum for effect cameras(none critical applications) but they could not replace high quality PMSE links for majority of the programm content. PMSE is unique in that it requires extremely low latency, below 5ms, an interference free spectrum and high quality reproduction (which is increasing with the use of HD and HD+/UltraHD) whilst a number of companies have attempted to develop equipment using modulation schemes such as LTE. Unfortenly the time delays and lack of bandwidth have proved insurmountable. Draft CEPT REPORT 50 Page 30 In recent years a number of cameras require a return link in order to control or synchronize the functions of the camera. This can include bandwidth( i.e. the bandwidth will increase with higher quality requirements) These links are currently in other spectrum Increase of bandwidth also depends on development of new codex Technology for PMSE equipment has enabled a reduction from some 30 MHz per channel to 10 MHz by the use of digital systems. However any further increases in spectrum efficiency would be difficult if not impossible to achieve with the increasing introduction of higher quality definition in broadcasting chain. Draft CEPT REPORT 50 Page 31 ANNEX 4: DEPLOYMENT SCENARIOS OF CORDLESS CAMERAS AND VIDEO LINKS Figure 1: Cordless Camera A conventional cordless camera transmitter docks on the back of a traditional camera. Audio is incorporated with the pictures on the cordless camera link either from an onboard microphone or else there may be a separate wireless microphone receiver mounted on the camera. Remote control of the camera for colour balance and exposure can also be by radio telemetry via a separate wireless channel received on the camera. Figure 2: Cordless Camera [Sorry, no suitable photo] Often to bring pictures from close to the action, miniaturised cameras and transmitters are mounted on participants in cycling and motorsport, utilising low profile antennas, such as patch antennas, to minimise the impact on performance. These can then be received on the ground via a network of switched receivers placed along the route, or received via an airborne platform. Draft CEPT REPORT 50 Page 32 Figure 3: Portable Camera Transmitter To give a reliable link over a greater range a Portable Camera Transmitter is used along with a directional antenna. In the example below, being moved to a new location, the transmitter, its only portable power supply, test equipment and the directional antenna are carried on a trolley. Once in place the camera is connected to it by cable. Typical applications would be motorsport or a golf course where the camera location is determined by the action. The equipment may also be mounted on a vehicle such as a golf buggy. Figure 4: Mobile vehicular video link Draft CEPT REPORT 50 Page 33 Mobile links can be mounted on a variety of vehicles including cars, buggies and motorcycles. In this example the cameraman sits on the rear of the motorcycle connected by cable to the video link, its components in the rear panniers and above the rear wheel. A low gain, typically a patch antenna, is mounted high, for safety and a clear view of the sky. Figure 5: Airborne video link The gyroscopically stabilised camera can be seen on the front of the helicopter with receive and transmit antennas mounted on the landing skids. Other airborne vehicles such as airships and tethered blimps can also carry airborne video links. As well as relaying pictures directly from the onboard camera the airborne platform can additionally receive multiple links from the ground, then transpose and transmit them down to another point on the ground. Below is an example of the onboard equipment required, perhaps for coverage of a marathon or cycle race. Draft CEPT REPORT 50 Page 34 Figure 6: Airborne video link equipment Figure 6: Temporary point-to-point video links Point-to-point video links are used to relay pictures, sound and data from remote locations to a central production location. Programme makers need their own high quality, low delay links to be able to seamlessly combine the elements of a production. These may be relatively short distances for an individual camera at a horse racing meeting or many kilometres from a remote outside broadcast part way along a cycle race, to the finish line. Draft CEPT REPORT 50 Page 35 9.1.1 Live Newsgathering It is commonplace to pair a cordless camera with a vehicle equipped with a satellite uplink or alternatively a terrestrial video link. There is the safety benefit and flexibility of not having to run cables between the camera and the vehicle as well as permitting optimum placement of the camera and vehicle link terminal. Figure 6: Cordless Camera for Newsgathering 9.1.2 Sports Coverage The rugged nature and reliability of digital cordless camera links has led to much greater use in coverage of sporting events. Cordless cameras are routinely deployed close to the action and can be handheld or mounted on moving vehicles. Figure 7: Cordless Camera for Sports Coverage 9.1.3 Major Events Live coverage of major state occasions, major cultural events and natural history programme making are greatly enhanced through the use of Cordless Camera and Video Links. Audiences have come to expect the wide range of shots from different standpoints along with close-ups that show the detail of the action. These are only possible when cameras can be located in a variety of locations, without the need to be cabled. Draft CEPT REPORT 50 Page 36 Figure 8: Cordless Camera for Major Event Coverage where cabling is not an option Portable Video links are employed where path lengths are greater, for example to provide reliable and rugged coverage over wide areas, perhaps an entire golf course. Lower power Cordless Cameras with shorter paths to a greater number of receive points are an alternative but practical and cost implications will determine the operational decisions. Multiple hops can permit a lower power Cordless Camera to be relayed on via a higher power video link perhaps rigged in a vehicle such as a motorbike or golf buggy. The use of video links has grown exponentially as the artistic freedom they create has resonated with producers and directors in all forms of media. Their deployment spans all forms of program making with variations in each sector for example the film industry uses “video assist” to allow the director to see the set from the remote cameras and the attachment of cordless cameras to formula 1 and rally cars or even whales and insects. Figures below provide an indication of their popularity: 9.1.4 Considerations on PMSE deployment scenarios and planning practice: The temporary nature of PMSE deployment can lead to less than optimum installation practices. Production vehicles and equipment are often corralled closely together creating radio frequency hotspots. Isolation between radio systems may therefore have to be compromised and it is not always possible to efficiently use spectrum in the way it would be possible with a permanent installation. The need to co-ordinate multiple PMSE users occupying the same ranges of spectrum can also limit the possibilities to promote the optimum use of spectrum in an operational environment where requirements are continually changing. Draft CEPT REPORT 50 Page 37 Figure 9: A temporary and less than optimum installation for Major Event coverage Draft CEPT REPORT 50 Page 38 ANNEX 5: A SNAPSHOT OF PMSE USE IN UK ON 20/8/12 A UK wide query in 2011 (as 2012 may skew the figures slightly due to the games) of Short-Term Business As Usual (BAU) allocations that appeared on a weekend. It has emerged that the sample on 20/08/11 would seem a good choice as there is quite a few events plus the spread of use across the UK (see map below). The following results for the ad-hoc short term use on 20/08/11 across the UK can be seen below: UHF 1 & 2 – 173 Assignments Band IV/V – 306 Assignments 2-4 GHz – 37 Assignments 7 GHz – 2 Assignments 12 GHz – 3 Assignments The allocations above spread across 53 different stakeholder/licensees Please note that the figures above for short term access amounts to 521. This amount does not account for the significantly large number of annual allocations approximately at 13,000, which represents theatres with annual microphone, monitors & talkback allocations, local radio, area & regional assignments, hospital radio, Point to Point Audio Links and National News. We can say that the subtraction of the Short term from Annual (521 from 13,000) will exist over any weekend period. The frequency range/spread for annual allocations also runs from 48MHz through to 12GHz. The Map below shows the allocations geographically Draft CEPT REPORT 50 Page 39 Just to re-iterate the data in the interests of this study only represents short-term allocations that took place on an ad-hoc basis.

Note that the demand for frequencies amount of spectrum allocation for the authorised frequency band for wireless microphones (470 MHz- 830 MHz band) is constantly increasing: 365 in 2007, 398 in 2008, 430 in 2009, 456 in 2010 and 463 in 2011. The number of frequencies for other uses has increased slightly compared to 2010: 287 in 2009, 319 in 2010 and 327 in 2011. 1389 radio equipment (walkie-talkies, microphones and cameras HF, talk back, special equipment for runners and the caravan of the Tour etc..) have been checked by the technical services of the ANFR. In order to help the professionals, 41 frequencies have been authorized for temporary use during this event. Also, 12 interferences appeared and were solved. 27 frequencies have been authorized in Band III, 392 frequencies in the band 470 MHz – 790 MHz and 75 frequencies between 790 MHz and 862 MHz for radio microphones. The following graph gives the statistic of the number of frequency authorizations per channel in the 470-862 MHz Draft CEPT REPORT 50 Page 47 Nb of authorisations Channel41 35 frequencies have been authorized for video links between 1467 MHz and 3779 MHz operated by 14 companies.
