ABSTRACT:
The present invention provides a distributed antenna system comprising a primary antenna (14A, 16A) and a plurality of secondary antennas (36, 40), between the primary antenna (14A, 16A) and the secondary antennas (36, one of the antennas (16A, 40) which transmits signals received by that (20, 22), and second means (32, 50) associated with a second one of the antennas (14A, 36) which causes that antenna (14A, 36) to transmit signals optic network (20, 22). Preferably, the use of a heterodyne fiber optic networks (20, 22) are modulated at radio frequency.
