Transceiver

From Freepedia

A transceiver is a device that has a transmitter and receiver which is combined into a one unit. The portmanteau term originates around World War II. Technically, transceivers must combine a significant amount of the transmitter and receiver handling circuitry. Similar devices include transponders and repeaters.

Electronics

In electronics, a transceiver refers to a device which combines both transmission and reception capabilities within a single housing. The term is used for semiconductor devices designed to send and receive digital data over a line or cable. Each communication network has its own transceivers such as RS232[1] used for computer to terminals communication, CAN-bus [2] used for industrial and automotive networks, LIN-bus[3] used for automotive sub networks, DC-BUS[4] used for automotive DC powerline communication.

Computer networks

In computer networking, a transceiver (sometimes abbreviated to TCVR) is a device that performs, within one chassis, both transmitting and receiving functions that is in a common housing, sometimes designed for portable or mobile use, uses common circuit components for both transmitting and receiving which provides half-duplex operation.

Transceivers were once commonly used in Ethernet 10BASE5 networks.

Radio technology

In radio terminology, a transceiver means a unit which contains both a receiver and a transmitter. It was quite common to have these units separated. Ham radio amateurs can build their own equipment and it is always easier to design and build a simple unit having one of the functions, transmitting or receiving. Almost every modern amateur radio equipment is now a transceiver but there is an active market for pure radio receivers, mainly for SWL operators. An example of a transceiver would be a walkie-talkie, or a CB radio.

Telephony

On a wired telephone, the handset is the transceiver for the audio. On a mobile telephone or other radiotelephone, the entire unit is a transceiver, for both audio and radio.
