Phone pager 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. Blackberry pager
Older forms of message submission using the Telocator Alphanumeric input Protocol protocol involve modem connections directly to a paging work, and are less subject to these delays. Many paging work operators now allow numeric and textual pages to be submitted to the paging works via email. Even more recent models included the ability to send messages in a two-way fashion and even included the ability to send and receive email. Since a one-way pager is a passive receiver only (it sends no rmation back to the base station), its location cannot be tracked. Many paging operators also support WCTP for sending and receiving messages from 1.5, 1.7 and two-way pagers. The paged party then had to telephone the control/call centre to collect the message either from an operator or an early voice mail device. Many paging operators also support WCTP for sending and receiving messages from 1.5, 1.7 and two-way pagers.

This is especially critical in hospital settings where emergency staff must be able to reliably receive pages in order to respond to patient needs. Pagers usually have very simple ring tones and some include a vibrating alert. Early pagers only provided an audio notification, such as a series of bleeps, to indicate reception of a page. Many paging operators also support WCTP for sending and receiving messages from 1.5, 1.7 and two-way pagers. Some early models included an analog audio receiver and speaker; upon receiving a page the speaker would activate, and the user would hear a human voice reciting their message. The slower POCSAG on-air protocol is still used for some pagers in the United States and probably in other countries. Phone pager. |
