On-Premise Wireless Paging Systems

A paging system is the combination of paging transmitters, control systems, and paging terminals. Paging systems are used to communicate information to a person carrying a mobile paging unit. Pagers are typically carried by people who wish or need to receive communications when they are away from a telephone or computer, or are unable to predict where they may be reached at a given time. Many business establishments today utilize on-premises radio paging systems to locate employees or notify customers when service is available. Paging systems typically include a paging terminal that interfaces with the public switch telephone network (PSTN) and a plurality of paging transmitters that provide signal coverage over a wide geographic region. The paging terminal network may then be connected to the public switched telephone network or other types of networks such as the Internet so that parties may generate paging messages for transmission to the mobile paging unit. In the paging system paging transmitters are connected to one or more paging terminals. The paging terminals formulate and format the paging messages and forward the paging messages to the paging transmitters for transmission. The paging transmitters transmit the paging messages in accordance with predetermined paging protocols, such as POCSAG, FLEX, and ERMES. Paging information is coded with a unique identification number and then transmitted to all paging receivers, with the receivers only receiving information having a specific identification number associated therewith. The paging terminal operates to supply the pages to be broadcast to each of the paging transmitters. The paging receiver or pager receives the signal, demodulates, and decodes the signal to recover the message, and presents the message to a user of the paging receiver.
