Radio waves for two way communication?

  1. Aug 20, 2014 #1
    Suppose I have a transmitter and receiver and my friend in the next room also has it. Can we both talk with each other with radio waves as we do in cell phone. I know we can't talk if he is several miles apart. But if he is just in the next room, can we communicate?

    Hi, Govind_Balaji, I will reply by asking a couple of questions :smile::


    Question 1: How do you think cell phones communicate?
    Question 2: Have you heard about walkie-talkies?

    How do you know this? :smile: . If you can communicate or not depends (partly) on the power of the transmitters.

    What do you think? :smile:

    I am actually doing a science project for an exhibition. It's tomorrow and I think of substituting cell phone microwaves with radio waves along with some wires and conductors. It's a bit difficult to explain here. I just had a doubt whether it's a flaw. So I just made sure it's complete.

    How were you intending to produce and receive your "Radio Waves"? What will the Science Project be saying and what is the planned audience?
