Portable

A Handportable Radio (sometimes known as a walkie-talkie) is a hand-held, portable, two-way radio transceiver. The major advantage of handportables is the “one-to-many” call (group calling) functionality. This enables a single user can pass a message to many listeners in a semi-duplex manner using “push-to-talk” (PTT) technology.
Modern 2 way radio systems are feature rich with additional functionality handportables such as Emergency calling, GPS tracking, Work order management, status messaging and many others.]
