A service request communication system for use in a restaurant or the like includes a plurality of transmitter units for sending requests, and a plurality of portable receiver units carried by service providers. The transmitter units include a keypad whereby a variety of service requests can be selected by a customer. On operating the keypad, a transmitter in the transmitter unit is activated, generating wireless signals which identify the transmitter unit and the type of service requested. The signals are received by the receiver units. In addition to a receiver, a typical receiver unit includes at least a microcontroller and a display. On regenerating the transmitter unit identification and the type of service request from the received signals, the microcontroller creates a list of requests according to a priority scheme. The list of requests is displayed on the display. The receiver units may include transmitters, allowing service providers to transfer service requests between receiver units.
