How about megaphones? Hmmm...Not real secure.Originally posted by moosa@Mar 1 2006, 08:57 AM
The first step in the project is a simple transmitter and receiver. They should be wireless and communicate within around 20 meters.
who can help me in this

Operating an RF transmitter on any old frequency is definitely not OK. Doing so may subject you to substantial criminal and civil penalties.Originally posted by moosa@Mar 3 2006, 12:02 PM
ok,
regarding the transmission by light or radio spectrum is ok. but radio spectrum is recommended with any frequency.
The data I want to transmit is numbers only. nothing else.
anymore questions ?

If you can get an IR link to span 10m, it's a lot easier to make a more pewerful transmitter to go twice as far, than to make a repeater.Originally posted by moosa@Mar 4 2006, 02:48 PM
Ok,
Thanx alot for philosophy. I needed solutions or suggestions not philosophy like doctors.
simply wireless communication within 20 meters. Whatever specification you like.
Of course, I wanted the easiest. I wanted suggested solutions not a specific design.
anyways, I have done it with my friends. We used simple infrared transmitters and receivers. We tested them in the lab today and they worked perfect for 10 meters. We will apply repeaters to cover the other 10 meters.
Now comes the other part, which is as follows:
we have one receiver and many transmitters. The transmitted data is numbers only.
I want the receiver to distinguish between each transmitter.
I mean if we have ten transmitters numbered from 1 to 10. Then, I want the receiver to know that this signal is coming from transmitter 1,or 2 or 3 .... etc.
any suggestions?
