Table 3 An overview of the extra restrictions on the available frequency bands for SRDs in the 863 to 870 MHz range [18]

From: Impact of EU duty cycle and transmission power limitations for sub-GHz LPWAN SRDs: an overview and future challenges

Nr. Start freq. (MHz) End freq. (MHz) Category Other restrictions
46b 863 865 High duty cycle/continuous transmission devices Only available to wireless audio and multimedia streaming devices
84 863 868 Wideband data Only available for wideband SRDs in data networks
47 865 868 Non-specific short-range devices Analog audio applications other than voice are excluded. Analog video applications are excluded
47a 865 868 RFID Interrogator transmissions at 2 W e.r.p. are only permitted within the 4 channels centered at 865.7 MHz, 866.3 MHz, 866.9 MHz, and 867.5 MHz. Maximum bandwidth of 200 kHz
47b 865 868 Non-specific short-range devices Only available for data networks. Transmissions only permitted within the bands 865.6-865.8 MHz, 866.2-866.4 MHz, 866.8-867.0 MHz, and 867.4-867.6 MHz. APC required alternatively other mitigation techniques with at least an equivalent level of spectrum compatibility
