Where does the action take place?
Relation to Draft ECC Report 218
•
It is planned to submit the draft ECC Report to the next WGFM meeting in February 2015
for public consultation approval. This ECC Report is complementary to the ECC Report
199 “User requirements and spectrum needs for future European broadband PPDR
systems (Wide Area Networks)”.
•
The process for this was triggered by ETSI SRDoc TR 102 628. The revised SRDoc also
includes a section on synergies and mentions possible synergies between BB-PPDR,
future railway communications and possibly other sectors such as ‘smart grids’.
•
Both, ETSI TR 102 628 and ECC Report 199 identifying 2x10 MHz as demand for BBPPDR wide area networks.
•
The RSPG Report on Sectorial Needs emphasises that the normal ETSI-ECC
collaboration process should be followed to express spectrum needs (means ..SRDoc!).
Note that there was also ETSI SRDoc TR 102 627 for E-GSM-R or ETSI TR 103 113 for
Urban Rail Systems (latter one in process in WGFM/ SRD/MG).
Draft ECC Report 218
Draft ECC Report 218 recognises a concept of “flexible harmonisation” to enable an efficient
implementation of BB PPDR within CEPT. This includes major elements:
•
•
•
•
•
•
common technical standard (i.e LTE and its evolutions)
national flexibility to decide on how much spectrum should be designated for PPDR
within harmonised tuning range(s), according to national needs
national choice of the most suitable implementation model (either dedicated,
commercial or hybrid)
National and international interoperability
Candidate spectrum ranges:
• 410-430 MHz,
• 450-470 MHz,
• 700 MHz (IMT-band 694 – 790 MHz) – several options
Noting that manufacturers can produce multiple band integrated chipsets, based on
common LTE advanced standards including the designated PPDR ranges, a common
technology for PPDR user terminals.
Roadmap – Note: current NB/WB PPDR in place at least until 2025/30
Synergies, Principles, Process
Principle of intelligent sharing (note that railways are not everywhere in a country, so the
frequencies could potentially also used by others, as long as the priorities are clear).
Normally bands are allocated as technologically neutral but could make specific for
Interoperability reasons (see draft ECC Report 218 -> LTE)
Support from administrations needed (administrations are also ETSI members!)
Frequencies below 1 GHz are strongly advised when it comes to rail safety related
applications and low latency required (beyond GSM-R)
Be aware of spectrum opportunity costs below 1 GHz for MFCN (ROM of 2 Euro/MHz/capita)
Include options in SRDoc incl. current GSM-R/E-GSM-R (e.g. for 1.4 MHz LTE studies?)
The philosophy is that LTE and further evolutions are used by the network and that user
equipment (cab radios and handhelds) have implemented multiple bands. The network
implementation and precise frequency option is then a national decision. All options are then
for LTE FDD. Apply possibly the same philosophy as for BB-PPDR.
Other Communcations
•
•
5.9 GHz perhaps for hot spots as mentioned in Urban Rail SRDoc (limited range of about
300m)
Video applications may also be able to use one of the options where PT SE7 is already
conducting compatibility studies for cordless cameras and video links such as for
surveillance cameras (do not include in the bundle for railway comms). Problem: regulators
cannot give each market sector their own ‘video’ frequencies -> need to differentiate and
not bundle everything to be < 1 GHz
•
Most radio bricks could provide support LTE on any allocated band. There are
presentations from several manufacturers demonstrating that adding bands in the radio
module, spanning potentially from 400 to 925 MHz is not an issue, also for the antennas
•
Note the many narrowband NB PMR authorisations in the 400 MHz bands (roughly
120,000 throughout Europe -> recent CEPT questionnaire). Difficult to find a common
harmonised slot for WB/BB applications.
•
Development of a new ECC Report in WGFM / FM54 may include some sections on
synergies. Timeline: work by early 2016.
