摘要： The present invention provides a method and apparatus for transmitting a synchronization beacon from a wireless base station to a wireless terminal in a wireless communication network installed in a building. The wireless network comprises a private branch exchange (PBX) connected to a wireless fixed base station (WFB) having a plurality of cell antennae units (CAUs) connected thereto. In a first embodiment, the plurality of CAUs are located in a single cell of the wireless network and are configured to receive two synchronization beacons from the WFB. In a second embodiment, each CAU is located in a separate cell in the network and is configured to receive a single synchronization beacon from the WFB. The synchronization beacon(s) is/are managed by the WFB and WT to virtually eliminate loss of synchronization between the WFB and WT if the frequency-timeslot at which the beacon is transmitted is changed or if transmission of the beacon is temporarily discontinued. In addition, synchronization between the WFB and WT is also maintained when the WT is moved to another cell in the wireless network.

摘要： A wireless terminal is disclosed that functions as both a telecommunications device and as a wireless test tool. Illustratively, the terminal comprises a first electro-acoustic transducer for converting a first acoustic signal into an outgoing signal; a wireless transmitter capable of transmitting the outgoing signal to a remote base station; a wireless receiver capable of receiving a plurality of incoming signals from the base station; a second electro-acoustic transducer for converting one of the plurality of incoming signals into a second acoustic signal; a visual display; and a terminal processor for determining a power level for each of the plurality of incoming signals and for contemporaneously displaying an indicium of the power level for each of the plurality of incoming signals onto the visual display.
