Two reasons why wireless systems aren't usually susceptible to HF RF -- 
very wide frequency separation, and no wires to act as receiving antennas.

The problem with RFI FROM wireless stations for weak signal UHF suggests 
a wired system -- IF you don't also run power on HF. :)

And if you're running a wired system around HF, use the best twisted 
pair you can buy, like CAT5/6/7, and wind turns on both ends around #31 
cores.
