Pager A portable, lightweight receiver of coded radio signals that indicates to its user that a message is waiting or someone is trying to get in touch. When people want to page someone that is, contact a person via the person's pager they telephone a paging service company, which then sends wireless radio signals to the pager. These signals, in turn, alert the pager's user by triggering a tone or a vibration. Most pagers can also deliver brief messages on liquid crystal displays. Because pagers do not rely on telephone wires, a page can be transmitted from a central location and received anywhere within the range of the transmitting tower.
Pagers make their users easy to contact, even if the user is away from a telephone.
As a result, pagers help increase productivity and improve responsiveness to emergencies and to business and personal requests. A page is the coded radio signal sent from a transmitter to the pager. Pages usually begin with the dialing of a telephone number to the user's paging service provider, a company that maintains the paging transmitters and radio equipment. Placing a telephone call to the service provider enables the caller to access a computerized terminal. The caller hears a tone or receives instructions on how to page a subscriber.
