Radio telephone equipment comprises three transceivers (14, 16, 24) arranged such that radio communication between an antenna of a telephone network, and a portable, low-power handset incorporating one of the three transceivers (16), takes place over two radio communication links, the two links being interfaced by the other two of the three transceivers (14, 24). Interference is reduced because the second communication link, to the transceiver (16) of the handset, can be based on radio frequencies substantially different from those selected for the first communication link between said antenna and the interfacing transceivers (14, 24). Further, the second communication link can be established in a manner independent of the nature of the first communication link. No fixed data link is necessarily required in addition to voice communication transceiving equipment. The radio telephone equipment finds particular application in cellular radio telephone systems. |
