Abstract
Apparatus for a radio local loop for a telecommunications system, such as a base station (1) or a subscriber station (2), comprises a first unit (4, 13), which includes call processing and speech transcoding/encryption apparatus (8, 17), and which can be housed in a friendly environment, such as within a telephone exchange or within a subscriber's premises, and a comparatively rugged second unit (3, 14) which includes a modem (11, 22) and radio transceiver (12, 23), and which can be housed, in the case of a base station, at a site remote from the exchange, but central for the subscribers which it is to serve, and in the case of a subscriber station on the outside of the subscriber's premises. The first and second units are linked by a base-band link (5, 15).
