Abstract
An elevator system () includes a wireless batteryless hall call switch module () that transmits a unique wireless code when a person presses a hall call button () requesting elevator service. A hall indicator module () includes an RF transceiver () that receives the wireless code from the switch module (), activates a display to indicate that a button has been pushed, and transmits the hall call information to the elevator control system (). When the elevator controller () informs the transceiver () of car arrival, the hall indicator module () causes the display to indicate car arrival.
