Roles of the three European regulatory organizations

European Commission:Single market issuesBinding regulations based on the technical expertise of CEPT/ECCand harmonised standards of ETSI (27 Member States)

CEPT/ECC:Consensus and voluntary characterSpectrum 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)

EC: Radio Spectrum Policy Programme (RSPP)

• Mobile broadband (1200 MHz)

• Spectrum Inventory

• Public protection and disaster relief (art. 8.3)

• Electricity production and distribution (Green...)

• Wireless microphones and cameras

• Foster different modes of spectrum sharing

• Spectrum Trading (where flexible use available)

CEPT/ECC: Strategic Plan

Priority topics:

•Digital dividend

•Cognitive radio

•Public Protection and Disaster Relief (PPDR)

•Innovation above 40 MHz

•Numbering and naming

•Improve its own working processes

Roadmap of the FM49 work

• FM49’s main task: find harmonised radio spectrum for the future European broadband PPDR system

• The concept of the future European broadband PPDR system: Wide Area Network (WAN) + Ad-Hoc networks

• ECC Report ”A” (requirements) – 2012 ECC Report ”B” (solutions) – 2013

• FM49 also supports the CEPT/ECC preparatory work for the World Radio Conference 2015 (WRC-15) Agenda Item 1.3 on the spectrum requirements for PPDR

FM49#04 meeting (14-15 June, Berlin) (1)

• The “Catalogue of PPDR Applications Related Requirements” was approved by FM49 and created a basis for the work on the ECC Report “A” (requirements)

• The work on the assessment of the necessary overall spectrum bandwidth for a BB PPDR Wide Area Network (WAN) was started based on the following assumptions:o applications: LEWP/RCEG-ETSI “Matrix of applications” o scenarios: LEWP/RCEG PP1 and PP2 scenarioso technology: LTEo frequency ranges: 400 MHz and 700 MHz (other

candidate frequency bands are also under discussion)

FM49#04 meeting (14-15 June, Berlin) (2)

FM49 followed several PPDR related activities outside CEPT:•ITU-R WP5A Work plan for the review and revision of PPDR related ITU-R Reports and Recommendations; start of the work on the preparation of the CPM text for AI 1.3 (on BB PPDR) of WRC-15

•Draft EC standardisatoin Mandate to CEN-CENELEC-ETSI on Reconfigurable Radio Systems (RRS) which, among other tasks, requests the development of European SDR architecture (and related interfaces) for civil security domain

•Decision of RSPG to develop an Opinion on Strategic Sectoral Spectrum Needs which also covers safety services and PPDR (Nov 2013)

•Approval in April 2012 by Asia Pacific Telecommunity Wireless Group (APT AWG) of a new APT Report on PPDR applications using IMT-Based technologies and networks

•3GPP activities on the inclusion of PPDR specific features into LTE specifications (Rel.12)

FM49#05 meeting (16-17 October, Helsinki) (1)

FM49 reviewed the results of the CG “Spectrum calculations” and endorsed the main estimates of the required spectrum bandwidth for a PPDR Broadband WAN*:

PP1 (day-to-day operations) PP2 (large emergency / public events)

Frequency band

Uplink Low estimate

Medium estimate

420 MHz 1 incident “cell edge”3 incidents near cell center and background communications

8,0 MHz 12,5 MHz

750 MHz 1 incident “cell edge”2 incidents near cell center andbackground communications

7,1 MHz 10,7 MHz

Frequency band

Uplink Less stringent case

Worst case

Independent of frequency band

PP2 traffic scenario with background communications

10,3 MHz 14,3 MHz

* It was decided to complement the CG's estimates with a sensitivity analysis which will be produced with the help of the LEWP/RCEG-ETSI “Matrix of applications”, now with the spectrum calculation functionality.

FM49#05 meeting (16-17 October, Helsinki) (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.

FM49#05 meeting (16-17 October, Helsinki) (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.

FM49#05 meeting (16-17 October, Helsinki) (4)

FM49 has also reviewed the draft ECC Report “A” “Applications related, operational and spectrum requirements for the future European broadband PPDR system (Wide Area Network)”:

•The ECC Report “A” was prepared on the basis of the earlier agreed “Catalogue of PPDR Applications Related Requirements” and will be complemented with the section on spectrum calculations at the next meeting.

•A "List of PPDR definitions" (the ‘common language’) which includes both the definitions agreed within the ITU-R and CEPT frameworks and those newly proposed by FM49, will be a part of the new ECC Report "A“.

•ECC Report “A” is expected to be ready for public consultation by the next meeting of WGFM (February 2013) and will be followed by an ECC Report “B” where solutions to satisfy the PPDR requirements identified in the ECC Report “A” will be addressed.

FM49#05 meeting (16-17 October, Helsinki) (5)

• The FM49#5 meeting has further discussed the “Table of candidate frequency bands” for harmonization of the future BB PPDR spectrum (earlier produced by FM38, the FM49’s predecessor). The discussion is currently focusing on the parts of the 380-470 MHz and on the 694-790 MHz as the candidate harmonized frequency bands for the European BB PPDR wide area networks.

• The meeting has also reviewed a proposal to consider mobile satellite solutions for BB PPDR wide area networks.

FM49’s next steps

• Finalize the draft ECC Report “A” (December 2012 and January 2013 FM49 meetings).

• Start the work on the ECC Report “B” (2013) where harmonised European BB PPDR frequency band(s) and solutions to deploy networks (i.e. dedicated vs. commercial) will be addressed.

• Start the work on a part of the new CEPT Report in response to the new EC Mandate on the 2 GHz unpaired bands (1900-1920/2010-2025 MHz) where PPDR Ad-Hoc networks are indicated as one of the high priority candidate applications (if requested by the ECC Plenary in November 2012).

• Provide support as required to the CEPT CPG Project Team “A” which is responsible for the CEPT preparation for the WRC-15 Agenda Item 1.3 (the future PPDR spectrum requirements).
