Table 3 An overview of the extra restrictions on the available frequency bands for SRDs in the 863 to 870 MHz range [18]
Nr. | Start freq. (MHz) | End freq. (MHz) | Category | Other restrictions |
|---|---|---|---|---|

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 |
