A transceiver is a combination transmitter/receiver in a single package. While the term typically applies to wireless communications devices, it can also be used for transmitter/receiver devices in cable or optical fiber systems.
The main functionality of this electronic device is to transmit, as well as receive, different signals.
In local area networks, the transceiver is a part of the network interface card. It can both transmit signals over the network wire and detect electrical signals flowing through the wire. However, some types of networks require an external transceiver.
In wireless communication devices, like smartphones and cordless telephones, the transceiver is built into the mobile device.
A transmitter is a separate electronic component that generates a radio frequency (RF) current or radio waves. These waves are used in communication systems to transfer data like audio, video, etc.
A transceiver, on the other hand, can both send and receive digital signals.
In radio communications, the transceiver can work in half-duplex or full-duplex mode:
The role of a transceiver depends on its type. There are four types of transceivers used in wireless communication systems:
