Abstract
A wireless signaling system includes a plurality of transmitters and a single receiver. The transmitter sequentially transmits serial data blocks to the receiver. Each data block includes a transmitter identification code and predetermined time intervals defining the beginning and end of the data block. The receiver receives the data block, detects the time intervals before and after the received data block to recognize reception of a complete data block, and checks the transmitter identification code included in the received data block to identify the transmitter.
