Pager service provider 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. In this use, they can be thought of as a modern equivalent of maroon rockets. Since a one-way pager is a passive receiver only (it sends no rmation back to the base station), its location cannot be tracked. Pager service provider. For this reason, older forms of message submission retain their usefulness for disseminating highly-important alerts to users such as emergency services personnel. Past paging protocols include Two-tone and 5/6-tone. Although 900MHz FLEX paging works tend to have stronger in-building coverage than mobile phone works, mercial paging service providers will work with large institutions to install repeater equipment in the event that service is not available in needed areas of the subscribing institution's buildings. Note that the idiomatic sound heard in popular media (movies and television programs) as "pager going off" (a series of two short beeps interrupted by a slightly longer pause) is actually the "pager power-up verification beep" sequence, perhaps because it was easier to generate that tone on demand (simply flip the power switch on). 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.

On a smaller scale, pagers are sometimes carried by staff in medical establishments, allowing them to be summoned to emergencies. Commercial paging transmitters typically radiate 1000 watts of effective power, resulting in a much wider coverage area per tower than a mobile phone transmitter, which typically radiates in the neighborhood of 0.6 Watt per channel.
