ECC Activities and Principles Applied for the IOT Future Spectrum Use

Thomas Weber, ECO Spectrum Manangement

The 4th Annual Internet of Things Europe, 12-13 November, Management Centre Europe, Brussels


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).


Proposal under Study (lower band)


Proposal under study (upper band)


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
