I have used the nRF24L01+ units for several projects.
Interference should not be too much of a problem. They can
be programmed to repeat many times until they receive an
acknowledgment. They also have long pipe IDs so it is
extremely unlikely anyone else will conflict.

I have some information posted here which may be useful:
