Motorola paging radio pager?

A pager is an electronic device used to contact people via a paging network. It pre-dates mobile phone technology, being most popular during the 1980s and 1990s, but similarly uses radio transmissions to communicate between a control/call center and the recipient. Many of today's pagers use the FLEX on-air protocol. The slower POCSAG on-air protocol is still used for some pagers in the United States and probably in other countries.
