Work in the ECC on Smart Grids / Smart Metering
(and others – under the UHF Roadmap)
•
Work in ECC WGFM SRDMG was triggered by 4 ETSI System Reference Documents:
–
DEFINITION OF THE REQUIREMENTS
ETSI SRDoc TR 102 649-2 (SRD and RFID appl, incl SM/SG, 870-876/915-921 MHz)
ETSI SRDoc TR 102 886 (SM in 873-876 MHz)
ETSI SRDoc TR 103 055 (SM/SG in 870-876 MHz)
ETSI SRDoc TR 103 056 (Alarms/Social alarms 870-876 MHz)
•
ECC WGSE is conducting spectrum compatibility studies
•
ECC WGFM SRD/MG collected spectrum inventory information and creates ECC
Report 189 which includes identification of the objectives/benefits, assessment of the
demand/of the ETSI request , need for harmonisation as well proposal for choice of
frequency regulatory framework and frequency options for each application
•
Full pan-European immediate harmonisation unlikely because of governmental services
in all or parts of the 870-876/915-921 MHz bands in 11 (of 48) countries.
SRD Strategy as applied under ECC Report 189 under
development
•
Frequency Management will focus on technology and application-neutral solutions to keep flexibility,
avoid spectrum fragmentation and foster innovations. At the same time, some applications need very
predictable sharing environments -> no special application categories in UHF for SM, alarms or
automotive applications, sharing is rather based on application-neutral medium access conditions.
•
Most applications are using Low duty Cycle / Duty Cycle. Some are organised in ICT networks (some
SM, M3N-> Metropolitan Meshed Machine Networks).
•
Smart Grids: seen almost exclusively on electricity generation side. Reliability, availability
requirements are very high (e.g. in the order of 99.9995%) and security issues attached. Seen as
incompatible with the SRD concept (no harmful interference, no protection). Either wired or use of
other available existing radio regulations (mobile networks, PMR/PAMR, Fixed Services)
Smart Metering
•
Metering scenarios, one can distinguish between
•
•
•
(a) meter - home gateway
(b) meter - neigbour gateway
(c) meter - network gateway
•
M3N combines the smart metering and smart grids by means of meshed networks
•
No exclusive frequency ranges foreseen
•
The use of the frequency range 169,4-169,8125 MHz is in the process of being revised and is available
for smart metering (complementary to UHF)
•
Sub-GHz bands between 400-500 MHz or 800-1000 MHz are the most cited in the discussions for
wireless metering technologies, offering a combination of large coverage area and low bit rates with
smaller coverage distance and higher bit rates.
•
The results of detailed investigations performed also confirm this view due to the propagation
characteristics above 1 GHz limit drastically the possibility to reach all the endpoint / metering sensors
in a network (often inside, or even in basements).

- An outcome of the first phase of SE43 activity relating protection of PMSE (ECC Report 159):
Sensing approach considered problematic solution;
A geo-location database considered feasible solution;
Safe harbour channel (s).
- Chapter 11 ”List of areas requiring further study” (ECC Report 159) suggests to continue technical
and regulatory considerations regarding protection of PMSE service.
-
ECC Report 186 (technical supplement to ECC Report 159) providing results on the outstanding
issues – currently under public consultation
Principle results may also be used in other bands
-
ECC Report 185 - currently under public consultation – covering geo-location w/o sensing – e.g.
requirements for master-slave WSD configurations and link to the geolocation database.
-
No definition of requirements via industry request/ETSI Srdoc !
-
WRC-15 Agenda Items 1.1 and 1.2 -> upper frequency edge may be lower in the future
