scope:
The present document specifies the minimum and optional requirements for system parameters of Time Division Multiple Access (TDMA) Point-to-Multipoint (P-MP) Radio Systems in the terrestrial Fixed Service operating in frequency bands in the range 3 GHz to 11 GHz.
The present document covers the following typical Point-to-MultiPoint (P-MP) applications:
- voice;
- fax;
- voice-band data;
- telex, related to analogue interfaces;
- data up to 64 kbit/s or beyond with optional interfaces;
- ISDN;
- digital video;
- digital audio, related to digital interfaces.
Radio terminals from different manufacturers are not intended to inter-work at radio frequency (i.e. no common air interface).
The present document defines the requirements of radio terminal and radio-relay equipment including the interfaces. The requirements for multiplex, network management and antenna/feeder equipment may be addressed elsewhere.
Testing to the present document will be undertaken with the guidance of a generic test methods document EN 301 126-2-1 [22], EN 301 126-2-3 [23] and EN 301 126-3-2 [24].
