Baseband Transmission


Baseband Transmission is a signaling technology that sends digital signals over a single frequency as discrete electrical pulses.

What is Baseband Transmission?

Baseband Transmission is a signaling technology that sends digital signals over a single frequency as discrete electrical pulses. The entire bandwidth of a baseband system carries only one data signal and is generally less than the amount of bandwidth available on a broadband transmission system.

The baseband signal is bidirectional so that a baseband system can both transmit and receive signals simultaneously. Baseband signals can be regenerated using repeaters in order to travel longer distances before weakening and becoming unusable because of attenuation.

Baseband transmission technologies do not use modulation, but they can use time-division multiplexing (TDM) to accommodate multiple channels over a single baseband transmission line.

Common local area network (LAN) networking technologies such as Ethernet use baseband transmission technology. All stations on a baseband network share the same transmission medium, and they use the entire bandwidth of that medium for transmission. As a result, only one device on a baseband network can transmit at a given instant, resulting in the need for a media access control method to handle contention.
