Foreword This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). Introduction Short Range Device (SRD) technology is technology of gro

12、wing use to interconnect sensors, actuators and remote control and monitoring systems. With time, technological progress and higher awareness of environment related questions will promote widespread use of sensor networks able to gather data at the scale of a city. Consequently, SRD technology will

13、be used to interconnect all of those sensors, actuators and infrastructures. The present document examines whether the performance requirements, access mechanism and transmitted power currently in use for SRDs are adequate for Metropolitan Mesh Machine Network (M3N) and opens a discussion on further

14、 work required to establish the magnitude of any compatibility issues in sharing the 870 MHz to 876 MHz frequency band. The present document identifies a relevant set of M3N applications that will transmit data over the M3N network. This permits to model a typical M3N deployment in term of number of

15、 devices, infrastructures and density. The same applications set also identify the key service requirements which will impact the volume of traffic to be transmitted between endpoints and network infrastructure. A structured mesh network is assumed as it accommodates the limited power available for

16、data transmission and minimises the number of gateways. The mesh traffic is modelled and the expected network performance established. This is then compared with the current SRD regulatory limits. The present document then discusses required changes in SRD rules to enable reliable and economically v

17、iable M3N operations. The discussion on compatibility assumes that the military services will be displaced by E-GSM-R and that it is with this service that the SRDs will share the frequency band. Intersystem interferences have already been addressed in TR 102 649-2 i.7 and TR 102 886 i.1, and is not

18、 repeated here. ETSI ETSI TR 103 055 V1.1.1 (2011-09) 61 Scope The present document applies to a new class of SRD devices specifically for Smart City applications operating in the UHF frequency band from 870 MHz to 876 MHz. It extends the discussion from Smart Metering Requirements discussed in TR 1

19、02 886 i.1 and TR 102 649-2 i.7 to a wider set of applications that are presented. Particular performance and compatibility parameters needed for the successful operation of SRD devices used in smart cities application are also identified. 2 References References are either specific (identified by d

47、work. As long as the interconnected devices have a high value such as town information display and parking meters the cost of GSM modules is a small proportion of the overall cost. Now, Machine-to-Machine (M2M) devices are often low cost, battery powered and transmit only small amounts of data. GSM

48、modules are consequently too expensive and consume too much power for such applications. Hence new wireless techniques have been developed for Machine-to-Machine devices operating under SRD rules to provide suitable low cost, low power connectivity. 5.1.2 From Smart Metering to Smart Cities Smart Me

49、tering has developed from early walk-by meter reading systems to fully bi-directional communications systems constructed as large scale networks. The benefits of improved communications capabilities are seen in lower operating costs, user-centric consumption information and improved energy production with reduced carbon emissions. Similar benefits can be gained in gas, heat and water supply as well as electricit
