I need to be able to reliably send potentially large amounts of data, in packet form over a ~100m max. range. I'm not as concerned about speed as reliability. I have been looking at the Hope RF12 from FutureLec and the nRF2401A from Sparkfun.
Is anyone familiar with these devices and would either suit my purpose or is there something else that I should be looking at.
I also need an inexpensive solution as I will be using quite a few of these devices in a master/slave application.
Thanks for any advice,
