Question

The frequency separation between each forward and reverse channel changes throughout the system.

(a) True

(b) False

This question was addressed to me in class test.

This is a very interesting question from Introduction to Multiple Access topic in chapter Multiple Access Techniques for Wireless Communications of Wireless/Mobile

Answer 1

Right option is (b) False

For explanation I would say: The frequency separation between each forward and reverse channel is constant throughout the system. It is regardless of the particular channel being used. A device called a duplexer is used inside each subscriber unit and base station to allow simultaneous bidirectional radio transmission.
