Abstract

A wireless data communication system for establishing a data link between a portable communication device and an interface circuit, such as an interface circuit to a LAN, includes a plurality of transceivers in communication with a control circuit. Each of the transceivers is configured to transmit and receive wireless signals within a defined transceiver space. The plurality of transceiver spaces combine to define a communication space. The control circuit detects the presence of a wireless signal within the communications space by sequentially scanning the transceivers to determine which transceiver is receiving the signal. Once the signal is detected, the control circuit automatically locks onto the transceiver receiving the signal, thereby enabling establishment of a wireless data link between the communication device and the interface circuit. The control circuit continues to monitor the established data link to determine whether data communications are disrupted. Upon detection of a disruption, the control circuit automatically attempts to retain the data link by re-initiating the scanning sequence.
