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
:

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).

It is expected that the

and 874 MHz. The exact frequency will be
determined following the compatibility study
when the impact of GSM
