Abstract
The disclosure relates to an asymmetric data access scheme eg Internet access scheme, over a fixed wireless access network. The disclosure provides apparatus for bandwidth efficient provision of asymmetric data services operating a method of communicating between a radio base station and a plurality of subscriber terminals, each subscriber terminal comprising a subscriber antenna. Each sector of a tri-sectored cellular arrangement operates a plurality of frequency division duplex pairs, plus one or more additional unpaired downlink frequencies. On the uplink, packet switched data is transmitted on the conventional access channel, eg ALOHA, but on the downlink, packet switched data is transmitted on an unpaired downlink frequency over a broad sectorized beam.
