A short description of “Duplexing, Frequency Division Duplexing, Time Division Duplexing”

Duplexing

  • In wireless communication system, it is often desirable to allow the subscriber to send simultaneously information to the base station while receiving information from the base station.
  • This effect is duplexing.

Frequency Division Duplexing

  • FDD provides two distinct bands of frequencies for every user.
  • A device called a duplexer used inside each subscriber unit and base station to allow simultaneous bidirectional radio transmission.

Time Division Duplexing

  • TDD uses time instead of frequency to provide both forward and reverse link.
  • In TDD multiple user share a single radio channel by taking turns in time domain.
  • We do not need any duplexing device.
