EVS-EN 303 204 V2.1.2:2017

The present document applies to the following radio equipment types:
1) Network Based SRDs which are SRDs intended to operate in association with other SRDs to form network
topologies supporting the intended application.
2) Network Relay Points which are specific Network Based SRDs supporting interconnection of a network of
SRDs with an external network or service.
These radio equipment types are capable of operating in all or any part of the frequency bands given in Table 1a.
Table 1a: Frequency bands designated to Network Based Short Range Devices
Network Based SRD frequency bands
Transmit 870,00 MHz to 875,6 MHz
Receive 870,00 MHz to 875,6 MHz
NOTE 1: The availability of the frequency band in Table 1a in European Union and CEPT countries can be obtained from the EFIS (http://www.efis.dk/) and is also listed in Appendices 1 and 3 of REC 70-03 [i.2].
NOTE 2: In addition, it should be noted that other frequency bands may be available for network based short range
devices in a country. See National Radio Interfaces (NRI) as relevant for additional guidance.
NOTE 3: On non-harmonized parameters, national administrations may impose certain conditions such as the type of modulation, frequency, channel/frequency separations, maximum transmitter radiated power, duty cycle, and the inclusion of an automatic transmitter shut-off facility, as a condition for the issue of Individual Rights for use of spectrum or General Authorization, or as a condition for use under "licence exemption" as it is in most cases for Short Range Devices.
The present document covers equipment intended for use in a fixed location, equipment normally fixed in a vehicle and
equipment intended to be carried or attached.
The present document contains requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference.
