Sounds like pretty much a line-of-sight situation? About how far? I may be overly optimistic and I don't know what I don't know, but I'd be surprised if there was a lot of trouble making it work.
I'm not familiar with the Nordic technology, but perhaps there is something similar available.
I'd go with XBee.With the amount of 2.4G around here I'm amazed at how well they work!Have a look at my Rover 5 video, both the XBee and the camera are on 2.4G.Neither minds a bit.My analogue 2.4G video sender/receiver is totally swamped, I had to shut down all the Phones, cell and cordless, AP's, Laptops, Netbooks to get a picture.So to use the analogue video link on my rover I bought a pair of 900Mhz XBee modules.
QuoteOne of these days I will go back and make the XBees my be-atch. They're going to work whether they want to or not.What kind of XBees are they? Series 1 models are trivial simple to make talk to each other. Fire up X-CTU, change 3 parameters and write the changes, and they work. Series 2 are not that much more difficult.
