Japanese Patent JP2002518875
Kind Code:
A
Abstract:
In transceiver apparatus, there is a plurality of sets (A-H) of substantially unidirectional antennae. Each set of antennae has a single radio subsystem for providing a radio output signal for transmission by one of the antennae in the set and for receiving a signal received by one of the antennae to provide an output signal from the radio subsystem. Each of the plurality of radio subsystems has a switch. The switch is operated to switch the output of the radio subsystem to a selected one of the antennae in the set for transmission of a radio signal by said selected antenna and to switch an input of the radio subsystem to a selected one of the antennae in the sets such that a signal received by said selected antenna is passed as an input to the radio subsystem.
