What is a pager? Is it the same thing as a beeper?
Basically, yes, Pager=Beeper. A Pager (commercial type through a pager provider) is a radio receiver that responds to a coded signal transmitted on a specific frequency (how and what frequency may vary). “Modern” pagers respond to a digitally coded signal, encoded with the serial number of the pager, and the message to display. It will only respond to the messages for it, including an audible signal. Some pagers have a vibrate mode similar to a cell phone. Older pagers just beeped, and responded to analog coding. To page someone, you call the number assigned to it, sometimes entering a code. The speaker paging is sort of the same idea, but uses a different medium ( a PA system rather than coded radio transmissions), but is only within the hospital/business/school, and is less discreet if a particular need has to be communicated. Often the PA system is connected with the buildings PBX (internal phone system), where you can call an extension or press a “Page” button on the phone set.
