  • Patent number: 4910511
    Abstract: In a radio paging system, radio paging signals contain a BCH (31, 16) format address and a BCH (31, 21) format address which are sent from a central station. The paper is assigned first and second BCH format user identification codes corresponding respectively to the BCH (31, 16) and BCH (31, 21) addresses. The pager has mode select switches for selecting the BCH (31, 16) address for local area reception or BCH (31, 21) address for wide area reception. When a paging signal is received, a coincidence is detected between the selected address and the corresponding BCH user identification code. When the coincidence is detected, the user is alerted to the reception by a paging signal. An appropriate channel is established in the local or wide service area.
