nRF24L01+ modules at 2.4 GHZ are getting popular. I have been using them fo=
r
local telemetry for a number of months. You can get really cheap rip-offs o=
n
eBay to experiment with.  I believe you can use the first 83 channels in th=
e
USA. Logitech uses this band for its wireless keyboards and mice.
