Cell phone pager Common paging protocols include Telocator Alphanumeric input Protocol (TAP), FLEX, ReFLEX, POCSAG, Golay and NTT. Pagers using the mercial FM band receive a subcarrier, called the Subsidiary Communications Authority, of a broadcast station. Many paging operators also support WCTP for sending and receiving messages from 1.5, 1.7 and two-way pagers. Cell phone pager. Pagers also have privacy advantages pared with cellular phones. Thus, if a pager has nationwide service, a message sent to it could be intercepted by criminals or law enforcement agencies anywhere within the nationwide service area. It pre-dates mobile phone technology, being most popular during the 1980s and 1990s, but similarly uses radio transmissions to municate between a control/call center and the recipient. This is convenient for many users, due to the widespread adoption of email; but email-based message submission methods do not usually provide any way to ensure that messages have been received by the paging work.

The slower POCSAG on-air protocol is still used for some pagers in the United States and probably in other countries. In the United States, pagers typically receive signals using the FLEX protocol in the 900MHz band. |
