RF Link

Hi, I am looking into a low cost RF solution to the following
situation:

I am designing a product that must maintain a constant communication
between device A and device B, with a range of just a few meters. I am
looking at Linx Technologies LR series. Any thoughts?

Thanks

Aerocom and someone else does that too, but IIRC Linx isn't FHSS, is

it?

What's your data rate? If you only need up to say, 2400 baud, maybe
4800, there's a cheaper (Tx/Rx < $10) 433.92 MHz solution.

Well here is the dilemma... I need to know if object A is too far from
object B, and if so will send a "1" to the chip in A. I was told that
RFID is the only technology avaible to do this easily, but RFID is way
too expensive to implement at this point. I was hoping to find another
low cost RF solution.

 

Thanks for your ideas!
