Abstract: A wireless network includes a wireless subscriber station radio-linked to a set of redundant wireless base stations, the set including a primary wireless base station connected to a secondary base station by a link, the link enabling sending and receiving baseband radio data to and from a radio or to and from another base station, a first base radio unit (BRU) connected to the primary wireless base station and a second BRU connected to the secondary base station, a data link connecting the primary wireless base station to the secondary wireless base station.

Abstract: A wireless system and method includes a frequency division duplex (FDD) system configured to provide at least a first FDD channel operating within a first frequency band. A time division duplex (TDD) system is configured to provide at least a first TDD channel operating within a second frequency band. The first frequency band and the second frequency band are separated by a third frequency band, and a half-duplex frequency division duplex (H-FDD) system is configured to provide at least a first H-FDD channel operating within the third frequency band. A transmission of the first H-FDD channel may be synchronized with one of an uplink transmission and a downlink transmission of the first TDD channel.

Abstract: An arbitration controller provides arbitration on a multipoint, high speed serial bus with a plurality of drivers. Each driver includes a data input pin, an output enable pin, and an output pin. The bus defaults to a first state when the output of the plurality of drivers are set to high impedance. The arbitration controller eliminates any unstable output states on the drivers by controlling the input signals on the drivers. The arbitration controller detects when the bus is in an arbitration mode. When this is detected, the arbitration controller inputs data to the output enable pin and inputs an opposite state of the first state to the data input pin. Further, the arbitration controller detects when the bus is in a data mode. When this is detected, the arbitration controller inputs data to the data input pin and inputs a driver control signal to the output enable pin.
