ABSTRACT:
A two-way paging system (10) includes a plurality of personal paging units (16). The personal paging units (16) receive pages (18), and generate radio signals (28) in response to the pages. The system includes a transmitter (12) for generating the pages, and a receiver (14). The receiver includes first and second receiving circuitry (30) and (34). The first receiving circuitry receives radio signals from the personal paging units. The second receiving circuitry receives radio signals from a source other than the personal paging units. The receiver further includes a data processor (32) electronically linked with the first and second receiving circuitry in the receiver. The data processor determines the time period during which radio signals are received from the personal paging units by the first receiving circuitry, based on radio signals received from the other source by the second receiving circuitry. In a preferred embodiment, the second receiving circuitry receives radio signals from the transmitter.
