ABSTRACT:
A communication system comprising a plurality of transceivers each being connected to selected ones of data inputs and at least one unidirectional antenna, each of the transceivers having a first transmitter coupled to the unidirectional antenna transmitting first signals at a first frequency to others of the plurality of transceivers according to a predetermined protocol and a first receiver coupled to the unidirectional antenna receiving second signals at a second frequency from others of the plurality of transceivers according to the predetermined protocol, the first and second frequencies being different; and a relay having an omnidirectional antenna in focused communication with the unidirectional antennas of the plurality of transceivers, a second receiver coupled to the omnidirectional antenna to receive the first signals according to the predetermined protocol and a second transmitter coupled to the second receiver and the omnidirectional antenna to convert the first signals to the second signals and to transmit the second signals to the others of the plurality of transceivers according to the predetermined protocol, each of the first and second signals including digital data combined with a pseudo-random spreading code having N bits common to all of the plurality of transceivers where N equals a predetermined number greater than two.
