Abstract:
Transceiver apparatus for use in a mesh of interconnected nodes in which each node comprises said transceiver apparatus and communicates with other nodes in the mesh via point-to-point substantially unidirectional radio transmissions, the apparatus comprising:a plurality of sets of substantially unidirectional antennas; each set of antennas having a single respective radio subsystem; each of the plurality of radio subsystems having a respective switch, each of said switches being constructed and arranged to switch a radio output of its radio subsystem at a particular time instant to one of the antennas in the set to which the radio subsystem is connected so that a radio signal output by the radio subsystem is transmitted by said antenna at said particular time instant, each of said switches being constructed and arranged to switch a radio input of its radio subsystem at another particular time instant to one of the antennas in the set to which the radio subsystem is connected so that a signal received by said antenna is passed as an input to the radio subsystem at said another particular time instant.
