Radio waves for two way communication?

Click For Summary

Discussion Overview

The discussion revolves around the feasibility of using radio waves for two-way communication between individuals in close proximity, specifically comparing it to cell phone communication and exploring the technical aspects of radio wave transmission and reception.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant questions whether two individuals with transmitters and receivers can communicate using radio waves if they are in the same room.
  • Another participant challenges the assumption that communication is impossible over longer distances, suggesting that it depends on the power of the transmitters.
  • A participant inquires about the method of producing and receiving radio waves for a science project, indicating a practical application of the discussion.
  • There is mention of walkie-talkies as a potential example of radio wave communication.

Areas of Agreement / Disagreement

Participants express varying levels of certainty regarding the ability to communicate using radio waves in close proximity, with some questioning the assumptions made about distance and power requirements. The discussion remains unresolved with multiple viewpoints presented.

Contextual Notes

Participants have not fully defined the parameters of their communication setup, such as the power of the transmitters or the specific technology being referenced, which may affect the feasibility of their claims.

Who May Find This Useful

Individuals interested in radio communication technology, science project development, or those exploring practical applications of physics concepts may find this discussion relevant.

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?

Why not?
 
Hi, Govind_Balaji, I will reply by asking a couple of questions :smile::

Yes...

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?
