Difference between Broadband and Baseband Transmission

  • Difficulty Level : Basic
  • Last Updated : 05 Jul, 2021

Broadband system use modulation techniques to reduce the effect of noise in the environment. Broadband transmission employs multiple channel unidirectional transmission using combination of phase and amplitude modulation. 

Baseband is a digital signal is transmitted on the medium using one of the signal codes like NRZ, RZ Manchester biphase-M code etc. is called baseband transmission. 

These are following differences between Broadband and Baseband transmission. 

Baseband transmission – 

  1. Digital signalling.
  2. Frequency division multiplexing is not possible.
  3. Baseband is bi-directional transmission.
  4. Short distance signal travelling.
  5. Entire bandwidth is for single signal transmission.
  6. Example: Ethernet is using Basebands for LAN.

Broadband transmission – 

  1. Analog signalling.
  2. Transmission of data is unidirectional.
  3. Signal travelling distance is long.
  4. Frequency division multiplexing possible.
  5. Simultaneous transmission of multiple signals over different frequencies.
  6. Example : Used to transmit cable TV to premises.
S.NoBaseband TransmissionBroadband Transmission
1.In baseband transmission, the type of signalling used is digital.In broadband transmission, the type of signalling used is analog.
2.Baseband Transmission is bidirectional in nature.Broadband Transmission is unidirectional in nature.
3.Signals can only travel over short distances.Signals can be travelled over long distances without being attenuated.
4.It works well with bus topology.It is used with a bus as well as tree topology.
5.In baseband transmission, Manchester and Differential Manchester encoding are used.Only PSK encoding is used.
