I don't think those devices will cause interference....

We have several Wi Fi systems and Wireless Routers running at our indoor track. How will this effect the Spektrum system?
These systems typically operate on the 2.4GHz band and, while they do occupy some of the bandwidth (channels), they must abide by FCC rules and incorporate collision avoidance. So while these systems can reduce the number of potential operators (there are 79 possible), the systems will operate harmoniously and not cause each other interference.

But how about this? There still have other safeguards even 2 transmitters are on the same frequency.....
What happens if two transmitters are on the same frequency? To be FCC legal, all 2.4Ghz devices must incorporate a collision avoidance system that prevents the system from transmitting on an already occupied frequency. The chance of two transmitters occupying the same frequency is highly unlikely. If two transmitters should somehow end up on the same frequency, other safeguards, such as the GUID and proprietary time base coding, will prevent interference. Of course, with the aircraft system, the transmitter is transmitting on two frequencies simultaneously. The odds of two transmitters transmitting on the same two frequencies is even, more unlikely but again, should this happen, other safe guards will prevent interference.
