How do beepers work? Are they still in use in this cell phone age?

A beeper is another term for a pager. A pager is a wireless communication device that has been around for several decades but became popularized from the late 70's through the early 90's. Pagers differ from more modern communication devices in that text based messages are sent from a base unit via a specific radio frequency to either a single mobile unit (the pager) or a network of units. You can think of it as the original version of text messaging. Some pagers can also receive audio messages or signals as well. When a simple pager receives a signal, it usually makes a beeping noise or some other type of sound to alert the user of a new message (hence the name "beeper"). Pagers containing a transmitter can also send messages to the central base unit as well.
Although modern cellular technology and text messaging has largely superseded pager technology for personal use, pagers do actually still find some specific uses today. They are still used in areas with no or unreliable cell service such as service tunnels or in areas where cell signals might interfere with sensitive equipment like hospitals or airports. They are also still very commonly used by restaurants for helping alert customers waiting for seating times.
