Introduction Wideband SRDs are a subset of the broader SRD family that can enable further market growth for divers applications including Internet of Things, Machine-to-Machine communications, smart home/building automation and wearables. This can be
20、achieved in particular through advanced characteristics of these devices such as higher data rates, improved power usage, and efficient spectrum utilization. Therefore, Wideband SRDs are expected to grow rapidly over the foreseeable future for mass market applications. Based on these expected growth
21、 rates and currently limited available frequency bands, there is an essential need for additional spectrum for Wideband SRDs to accommodate the anticipated market growth. The present document requests modifications to the regulatory rules of the UHF 870 - 876 MHz and 915 - 921 MHz frequency bands to
22、 enable the operation of Wideband SRDs with advanced spectrum sharing capabilities in these bands. ETSI ETSI TR 103 245 V1.1.1 (2014-11) 51 Scope The present document applies to the potential future usage of Wideband SRDs with advanced spectrum sharing capabilities in the UHF 870 - 876 MHz and 915 -
23、 921 MHz frequency bands. In particular, it: Gives an SRD market overview and explains the development and emergence of new Wideband SRD technologies. Describes technical characteristics of Wideband SRDs, including advanced spectrum sharing capabilities, as they relate to the usage of the UHF 870 -
24、876 MHz and 915 - 921 MHz spectrum. Details the requested regulatory changes to allow for efficient use of Wideband SRDs. The present document is intended to include all necessary information required by the Electronic Communications Committee (ECC) under the MoU between ETSI and the ECC. 2 Referenc
