Abstract: A method and apparatus for establishing communication paths includes a portable transceiver carried or worn by a company representative, for communicating in a wireless mode of operation with a stationary base station, thereby enabling the representative to move freely about for performing multiple tasks. A plurality of customer stations outside of the company building are connected electrically to the base station, which includes a switching arrangement to select an individual one of the customer stations for connection to a base station transceiver. The portable transceiver includes a single input device in the form of a push button paging switch for each customer station. The single device causes a customer station to be selected, a communication link to be established and terminated, and controls both the customer and the representative audible communications.

Abstract: A wireless communication system is adapted to be used as an intercom system in a multiple customer station configuration. A customer service representative portable transceiver communicates wirelessly with a stationary base station to enable the representative to move freely about, and thus be able to perform other tasks. The base station is connected electrically to a group of substantially similar physically spaced apart remote customer drive up stations. Each of the remote stations includes a call initiating device for enabling a customer at a drive up station to request communications with the representative. The base station includes a signal generator, which responds to a call initiating device requesting a communication link. A transmitter responds to the generator to send an attention attracting signal to the representative's transceiver, so that the representative can cause the establishment of an audio communication link to a selected customer station.
