FIELD: communications engineering.
SUBSTANCE: stationary wireless access system has, as a rule, user's room equipment unit connected through Ethernet interface to personal computer or to local network and base station unit connected through Ethernet interface to network. User's room equipment unit as such is easily installed by user while base station unit is usually mounted on mast at distance of 1 to 5 miles (1/6 to 8 km) from user's room equipment unit. Both the latter and base station unit usually incorporate integrated transceiver/data switch that provides for radio-frequency communications in the range of 2.5 to 2.686 GHz. Multiplexing with orthogonal frequency division of signals is used during transmission between user's room equipment units and base station ones over ascending and descending lines.
EFFECT: provision for using outwardly accessible antenna affording transmission within line-of-sight range.
