Hi I'm fairly green when it comes to RF technology in circuits.
Here's my problem: I need a low power RF transmitter module (3 - 5v) for my application. It's a small embedded device and all it does is broadcasting a short ID to a base station.
My circuit is very small, it's a battery powered AVR. The AVR holds the unique ID to be broadcast when a certain logic criteria is met.
And to make things complicated, There will be multiple of these broadcasting their IDs to the base station, probably up to 1000 devices broadcasting once per 5 seconds which is 200 times per second. I need the range about 500ft or more.
I'm guessing something that broadcasts in the ISM range will work but I'm open for any design ideas.
So long story short; What TX/RX chips would be good to use? Also, how what would be the best way of getting a message through in such a crowded network?
