Fixed Short Range Devices (SRD) in data networks - Radio equipment to be used in the 870 MHz to 876 MHz frequency range with power levels ranging up to 500 mW e.r.p. - Harmonised Standard for access to the radio spectrum

The present document specifies technical characteristics and methods of measurements for the following types of equipment:
Type 1 equipment: SRDs in data networks:
Type 1a: Terminal nodes
Type 1b: Network nodes
Type 1c: Network access points
Type 1a terminal nodes and type 1b network nodes are fixed SRDs, operating up to 500 mW e.r.p. and with adaptive power control, which are intended to operate in association with other SRDs to form data network topologies supporting the intended application.
Type 1c network access points are specific fixed SRDs, operating up to 500 mW e.r.p. and with adaptive power control, supporting interconnection of a network of SRDs with an external network or service.
These radio equipment types are capable of operating in all or part of the relevant frequency bands given in Table 1.
