Title:
TOWER TOP CELLULAR COMMUNICATION DEVICES AND METHOD FOR OPERATING THE SAME
Document Type and Number:
WIPO Patent Application WO2003019799
Kind Code:
A3
Abstract:
A cellular network (100, 200) and method are provided that reduce loses between a base station (102, 202) and an antenna (114, 214). Generally, the network (100, 200) includes a tower (112, 212) having a tower-top (110, 210) on which the antenna (114, 214) is supported, a base station (102, 202) and a separate amplifier (124, 224) on the tower-top near to the antenna, the amplifier in a communication path between the base station and the antenna. In one embodiment, the network (100, 200) further includes a backhaul (122, 222) on the tower-top (110, 210) near the antenna (114, 214), the backhaul configured to couple signals between the base station (102, 202) and a controller (108, 208). Preferably, the backhaul (122, 222) is integrated with the base station (102, 202). In another version, the backhaul (122, 222) is configured to couple communication signals between the base station (102, 202) and the controller (108, 208) via a radio network (128, 228). More preferably, a photovoltaic cell (132, 232) on the tower (112, 212) supplies electrical power to the base station (102, 202), the amplifier (124, 224) and the backhaul (122, 222), thereby providing a self-contained tower-top node (134, 234).
