A handset is a component of a telephone that a user holds to the ear and mouth to receive audio through the receiver and speak to the remote party via the built-in transmitter.
In earlier telephones the transmitter was mounted directly on the telephone itself, which was attached to a wall at a convenient height or affixed to a desk stand.
Until the advent of the cordless telephone, the handset was usually wired to the base unit, typically by a flexible tinsel wire.
The handset of a cordless telephone contains a radio transceiver which relays communication via a base station that is wired to the telephone line. A mobile phone does not require a base station and communicates directly with a cell site in specially designated frequency bands.
Handset symbol
A graphic symbol that designates a handset is used on cordless and mobile phones to specify placing or ending a telephone call. Usually a button with green upright (off-hook) handset icon ){kind=small}
is used for starting a call, and a red lying-down (on-hook) handset ){kind=small}
is used for ending a call.[1] Unicode provides the U+1F4DE TELEPHONE RECEIVER symbol.
