适用范围
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].
