Roles of the three European regulatory organizations
European Commission:
Single market issues
Binding regulations based on the
technical expertise of CEPT/ECC
and harmonised standards of ETSI
(28 Member States)
CEPT/ECC:
Consensus and voluntary character
Spectrum designation to
systems/applicatoins and technical
conditions for its use
(48 member countries)
ETSI:
European Harmonised standards (EN) for radio equipment
‘System Reference Documents’ (SRDoc) which inform and trigger
much of the CEPT/ECC work
(over 700 industry members and European naitonal regulators)
Regulatory actors on the scene of broadband PPDR harmonisation

Communications
Association
International Telecommunication Union (ITU)
ITU is the United Nations agency for ICT
ITU-R Working Party 5A is responsible for
Agenda Item 1.3 of WRC-15 (revision of regulatory
provisions for PPDR, including regionally harmonised
frequency bands)
ITU-R WP 5A acts as a global architect for shaping
future look of broadband PPDR communications
ITU-R WP5D “IMT Systems” addresses the PPDR
needs from the IMT technologies perspective
European Commission
European Commission is setting out
policy priorities and long-term objectives
for wireless broadband, including Public Safety
Radio Spectrum Policy Programme (RSPP):
Article 8.3:
The Commission shall, in cooperation with the Member States, seek to ensure
that sufficient spectrum is made available under harmonised conditions to
support the development of safety services and the free circulation of related
devices as well as the development of innovative interoperable solutions for
public safety and protection, civil protection and disaster relief.
LEWP-RCEG (Home and Justice Affairs, European Council)
Radio Communications Expert Group of the
Law Enforcement Working Party is composed
of senior representatives from PPDR agencies and
regulatory authorities of EU and EFTA Members
LEWP-RCEG adopts statements setting out mid- to long-term
objectives based on the needs of European PPDR community
• Statement of LEWP-RCEG (October 2012):
LEWP-RCEG asks ECC/CEPT WGFM to take into account the PPDR
needs for a mission critical Broadband solution and for this purpose to
allocate harmonised frequencies
ETSI
European Telecommunications Standards
Institute develops Harmonised Standards (EN)
for telecommunication equipment, including for Public Safety
ETSI is also developing Technical Reports (TR) which both
support ETSI’s standardization work and CEPT’s spectrum
management activities (as SRDoc):
• ETSI TR 102 628 (SRDoc) on additional spectrum requirements for
public safety and security in the UHF frequency range
• New (draft) Work Item in TETRA TC aimed at updating TR 102 628
to include more detailed calculations to justify the requirements, and
to reflect the changes in the external environment
3GPP
3GPP provides technical environment for producing
LTE specifications, including for Public Safety
3GPP TSG Service and System Aspects (TSG-SA) is working
on the inclusion of PPDR specific features in 3GPP Release
12 (target date: September 2014), namely:
• Mission critical voice and data PTT group communication
capability (GCSE_LTE), and
• Direct device-to-device communications (ProSe*)
* It is likely that not all ProSe functionality will be included in 3GPP Rel-12;
some of the remaining functions will be specified in later 3GPP releases
TETRA + Critical Communications Association (TCCA)
TCCA is a forum for all professional users,
both Public Safety (mission critical)
and Utilities & Transport (business users)
TCCA is developing community’s:
• user requirements
• systems and architectures, and
• business cases
TCCA is communicating its needs from “first hands” to
regulatory bodies (first of all, to CEPT), to ensure
timely allocation of sufficient resources

ECC Report 199 (”A”): spectrum estimates (2)
Comments on the PP1 and PP2 estimates of the required spectrum:
PP1 (day-to-day operations)
•
The difference between the estimate for 420 MHz and 750 MHz is due to the fact that the
size of cells at 400 MHz is larger than the size of 700 MHz cells. This implies that more
incidents can occur and thus more throughput.
PP2 (large emergency / public events)
•
The PP2 estimate is based on a single PP2 scenario (the UK royal wedding). This
estimate does not take into account possible additional capacity (an ad-hoc network) that
could be set up in such a case.
DR (Disaster Relief)
•
The DR scenario has not been addressed. It can be assumed that the amount of
spectrum required for PP1 scenarios would be minimal for a DR scenario.
ECC Report 199 (”A”): spectrum estimates (3)
Technical aspects related to the estimates of the required spectrum:
•
In the values shown in the Tables only the uplink requirements are presented as they are
the most constraining (the downlink bandwidth is assumed to be of the same size).
•
The difference between the “low” / “less stringent case” and “medium” / “worst case”
estimates for PP1 and PP2 respectively is not in the traffic models (both correspond to
the identical throughput) but in the spectral efficiency assumptions.
•
The assumed relatively high value of the uplink spectrum efficiency at the cell edge (0.31
bit/s/Hz) is mainly justified by the need to enable the provision of broadband PPDR
applications, first of all real-time video, at the cell edge under the envisaged limited
amount of spectrum potentially available for BB PPDR.
•
The main implication of this assumption is the requirement for more base stations in the
future BB PPDR WAN, in particular in the urban environment. However a trade-off
between the uniform ‘broadband coverage’ and the cost of the network is possible at the
stage of the network radio planning.
•
DMO and mission critical voice have not been taken into account in the calculations. The
provision of these services within the BB PPDR network may require additional spectrum.

ECC PT1’s progress of work (1)
ECC PT1 is the CEPT specialist project team on IMT
(chairman Mr Didier Chauveau, ANFR, France)
ECC PT1 was designated as the CEPT lead group for producing CEPT
Report in response to the EC Mandate on 700 MHz
The EC Mandate recognizes PPDR as a “priority area of EU spectrum
policy” and requires CEPT to develop a preferred channeling
arrangement and least restrictive technical conditions (Block Edge
Masks) for wireless broadband in the 694-790 MHz which would also be
suitable for the provision of PPDR services.
FM49 is supporting the work of ECC PT1 by providing assumptions and
relevant technical parameters for future PPDR networks in the 700 MHz
for coexistence studies with broadcasting at the 694 MHz boundary.
ECC PT1’s progress of work (2)
ECC PT1 is studying the following 700 MHz band plan options:
Joint work of CEPT groups on candidate bands for BB PPDR
• FM49 has identified 700 MHz (694-790 MHz) and 400 MHz (410-430
and 450-470 MHz) as candidate BB PPDR bands. The 2 GHz
unpaired bands (1900-1920 / 2010-2025 MHz) are considered as an
option for PPDR ad-hoc networks
• ECC PT1 will define technical conditions for wireless broadband in the
700 MHz band which will be also suitable for PPDR (May 2014)
• WG SE will make a new technical study on the feasibility of the
deployment of PPDR LTE networks in the 410-430 MHz and 450-470
MHz, including the development of technical conditions (early 2015)
• WG FM will develop a 400 MHz PMR/PAMR questionnaire to reveal
the actual usage (such as N of individual licences, digital/analogue,
technology in use etc.) for frequency ranges: 406.1-410 MHz, 410-430
MHz, 430-440 MHz, 440-450 MHz, 450-470 MHz (January 2014)

CPG PTA’s progress of work
CPG PTA is the CEPT project team responsible for, among
others, CEPT preparations for Agenda Item 1.3 of WRC-15
(CEPT coordinator for AI 1.3 of WRC-15 Mr Andrew Gowans, Ofcom, UK)
• CPG PTA relies on the results of FM49’s work on BB PPDR, in particular on
the main conclusions of ECC Report 199
• CPG PTA is contributing to the ITU-R process of preparations for Agenda
Item 1.3 of WRC-15 (main issue for Europe – new PPDR frequency bands
for Region 1 in Resolution 646 (Rev. WRC-12) providing regionally
harmonised bands for PPDR)
• CPG PTA is developing an input to ITU-R WP5A supporting a single ITU-R
Report covering all aspects of PPDR, including broadband. Consequently,
the current major Report ITU-R M.2033 on PPDR objectives and
requirements from 2003 should be suppressed
Next steps
• Identify the European preferred frequency bands or
frequency tuning range and technical conditions for
hamonised provision of broadband PPDR services
• Promote the European arrangement for broadband
PPDR at the international level
• Urge European regulators to make spectrum available
for broadband PPDR in a timely manner, to ensure
interoperable and affordable provision of PPDR
services, for the sake of European citizens
