RE: Cell phones ?
Probably not.
Cell phones operate on in variety of frequency ranges, none of which are on near or harmonically related to RC aircraft frequencies. Any radio can become detuned and transmit outside of it’s intended band (called spurious emissions) but this is very unlikely. Also the power is very, very low. Maximum power from a standard handset is around 0.6w and then turned down by the tower once a call is in place to the lowest level needed to support a call.
If your cell phone is Bluetooth enabled, it will also be on the 2.4ghz band which is shared by RC and many other devices. However, these power levels are even lower than a cell phone and are all but unusable past a few dozen feet.
Are you searching for the source of a glitch or just curious?
