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
(27 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)
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 scenarios
o technology: LTE
o 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 ITUR 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)
Frequency
band
420 MHz
750 MHz
Uplink
1 incident “cell
edge”
3 incidents near
cell center and
background
communications
1 incident “cell
edge”
2 incidents near
cell center and
background
communications
Low
estimate
Medium
estimate
8,0 MHz
12,5 MHz
7,1 MHz
10,7 MHz
PP2 (large emergency / public events)
Frequency
band
Uplink
Independent of
frequency
band
PP2 traffic
scenario with
background
communications
Less
stringent
case
10,3 MHz
Worst
case
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).
