REDUNDANT BROADBAND MULTI-CARRIER BASE STATION FOR WIRELESS COMMUNICATIONS USING OMNI-DIRECTIONAL OVERLAY ON A TRI-SECTORED WIRELESS SYSTEM

摘要

A broadband multi-carrier base station for wireless communication (10), such as cellular telephone or personal communication systems has three sets of broadband transceivers (32, 33, 34) and antennas (35, 36, 37, 41, 42, 43) forming a standard tri-sector or tri-cell coverage pattern. A fourth transceiver (31) coupled to a substantially omni-directional fourth antenna (11, 29) that has a coverage area overlapping the tri-sector or tri-cell coverage pattern. Thus the fourth broadband transceiver (31) and fourth antenna (11, 29) provide redundant communication in the event of a malfunction of one of the other broadband transceivers.
