There are essentially two kinds of transponders. Regenerative transponders and bent pipe transponders are those.

A signal-sending gadget is called a transmitter. When the operator keys, a transceiver—a transmitter and receiver—transmits. Transceivers are typically used for voice communications. A transponder is a receiver and transmitter that is connected so that a transmission is sent in response to a request.

Several channels, or transponders, that supply power and bandwidth across certain radio frequencies are found on a satellite. The amount of data that can be transmitted by the transponder and the size of the ground equipment required to receive the signal depend on the bandwidth and power of the transponder.

In a communications satellite, a satellite transponder receives signals over a range of uplink frequencies, usually from a satellite ground station; the transponder amplifies them, and re-transmits them on a different set of downlink frequencies to receivers on Earth, often without changing the content of the received ...

Transponder A: provides ATC with a transponder code. Transponder C: provides ATC with an altitude reading along with a transponder code. Transponder S: receives and reports data to other transponders of the same type. Transponder S transmits a transponder code and altitude information to ATC.

A transponder is a wireless monitoring, communication, or control device that detects incoming signals and reacts to them automatically. The word is a compound of responder and transmitter.

RFID makes use of transponders, which are also known as tags but are also shaped like cards. Transponders' chip memory stores specific, individual ID numbers that are assigned to them at all times. Transponders dubbed "smart card" models have extra memory to hold far more information than just an ID number.

The signal from the transponder, which is typically far greater than the reflection received by the primary surveillance radar, identifies the aircraft. All SSR systems employ 1030 MHz as the uplink frequency from a ground-based interrogator, and 1090 MHz as the downlink frequency from an aerial transponder.

In general, a transceiver is a device that can send and receive signals, whereas a transponder is part of a fiber optic communication network that has a processor that is set up to monitor incoming signals and respond with a preprogrammed response.

The satellite's transponder, a repeater system, receives the feeble signal from Earth and amplifies it before sending it back to the planet. A beam is the area that a satellite's signal covers on Earth.
