Advantages and Disadvantages of Baseband Transmission


  • Simple structure
  • Low cost installation
  • Ease of installation
  • Maintenance is easy


  • Limited distance
  • It can be used for only data and voice
  • Short coverage and limited range

Broadband Transmission

  1. Many signals with various frequencies can be transmitted simultaneously
  2. Analog signals are used in broadband transmission of data
Broadband Transmission

3. It can be used for long distance transmission

4. It uses uni-directional transmission

5. Frequency division multiplexing is possible

6. It can used with both tree and bus topology

7. PSK i.e.. Phase Shift Keying encoding scheme is used

8. It offers maximum bandwidth of 1 to 100 Mbps

Advantages and Disadvantages of Broadband Transmission


  • Data, voice and video all can be supported
  • It offers greater bandwidth


  • Cabling is complex
  • Maintenance is a major task
  • High Monetary is needed for installation
  • High Cost
