ABSTRACT:
In the service request communication system disclosed herein, a plurality of battery-powered table units communicate a variety of service requests to a central server or master unit by a bi-directional wireless radio frequency data link. The table units remain in a low-power "sleep" state until any one of a plurality of switches is actuated by a customer to denote a corresponding service request. A transceiver is controlled by a microprocessor to transmit a coded signal identifying the request and then to receive and indicate to the customer an acknowledgment signal transmitted from the server or master station. At a server station a display is operated to identify the table unit/request combination, the display being canceled when a corresponding switch at the server unit is actuated, e.g. by the employee who will provide the service requested.
