one rf transmitter & more than one rf receiver

[kunal123]

hello,
can one rf transmiiter & more than one rf receiver network work fine, if yes suggest me which rf module i should use

thanks & regards

Any should work. What you are suggesting is used everywhere, TV, radio, mobile phones etc. One transmitter's signal can be picked up by as many receivers as are in range.

Single transmitter with Multiple receivers is the basic concept of FM and AM. Most commonly, in a TV, AM is used to broadcast video while FM is used to broadcast audio signal.

which rf transmitter & which rf receiver i should use?

Try CC2500 Transceiver module.. It works in ISM band. It might suit your requirements.

my idea is there are rf receiver work on different frequency & there is one transmitter generate different frequency

Your original question was "one transmitter, many receivers" which was correctly described above as a broadcast system.
Now you switch to "many frequencies" which changes the problem completely.

What exactly do you want?

No, it's the basic concept of broadcasting. The type of modulation is irrelevant.

Sparkfun sells some simple rf transmitters but you might want to look into bluetooth as it seems a lot more reliable. The ones sold on ebay might be a decent choice. I have two but I haven't used them so I can't say for sure they would work in your case. In fact does anyone know if such transceivers are capable of sending to multiple receivers?

Syncopator is perfectly right. There are several 433MHz modules available. you can use them if you don't need an acknowledgement from the recepient.

I think the OP wants to use a single transmitter to send several unique signals, each of which will be received by only one of several receivers. This can only be done with a complex system of sub-carriers and/or encoding-decoding.
