A method of conserving battery energy within two-way radios by periodically de-activating the radios for relatively short time periods. The transmission and reception of communication requests are synchronized to occur during concurrent periods of activation. Following receipt of a communication request, requestor and target remain continuously activated for only the duration of the transaction. Synchronization of radio activation and de-activation is maintained by a synchronization beacon transmitted by a base station or a transmitting portable radio. |
