  2. 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.

  3. 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)

  4. 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).

  5. Proposal under Study (lower band)

  6. Proposal under study (upper band)

  7. Work in the TV White Spaces 470-790 MHz - 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
