Abstract
A method in a communication system (100) having a high power transmitter (104) for transmitting messages to selective call receivers (102) located within a wide coverage area (114), and having at least one low power transmitter (108) for transmitting messages to selective call receivers (102) located within a smaller, overlapping coverage area (112). The transmitters (104,108) transmit on the same frequency but during different time intervals, except that mutually remote, low power transmitters can transmit simultaneously. A selective call receiver (102), adapted to operate in the communication system, and having a special arrangement of canned messages (412), can determine its location based, at least in part, on the time interval during which it received a message.
