Half-Duplex Mode in Transmission

 

TRANSMISSION

Half-Duplex Mode 



In half-duplex mode, each station can both transmit and receive, but not at the same time. 

When one device is sending, the other can only receive, and vice versa. 

The half-duplex mode is used in cases where there is no need for communication in both directions at the same time. 

The entire capacity of the channel can be utilized for each direction. 

Example: Walkie-talkie in which message is sent one at a time and messages are sent in both directions. 


Advantages:


Half-duplex mode allows for bidirectional communication, which is useful in situations where devices need to send and receive data.

It is a more efficient mode of communication than simplex mode, as the channel can be used for both transmission and reception.

Half-duplex mode is less expensive than full-duplex mode, as it only requires one communication channel.


Disadvantages:

 

Half-duplex mode is less reliable than Full-Duplex mode, as both devices cannot transmit at the same time.

There is a delay between transmission and reception, which can cause problems in some applications.

There is a need for coordination between the transmitting and receiving devices, which can complicate the communication process.
