Q - Explain infrared communication?

    

Unguided infrared and millimeter waves are wildly used for short range communication.

         The remote control used on television VCR and stereos used infrared communication. They

         Are relatively but have a moor drawback, they do not pass throw solid object.

       Advantage:-

 

        ---> Infrared communication are secure systems because, the signal will not leave in   particular range.

        ---> Infrared are being able to use own receiver with public transmitters.

 

       Disadvantage:-

 

        ---> Receivers are required for all users.

        ---> Large area requires multiple emitter panels, which will increase the cost of system.
