We generally use 2.4Ghz when flying and that is generally not used for mobile/data communication. They use something like 2.1/2.3 and 2.5Ghz when running 4G so don’t interfere with us at all. Having said that, my original broad wifi used on a Phantom 3 used to cop a beating when flying close to dense housing with their routers overpowering my efforts to fly. These days we have DJI using their own closed ecosystems like lightbridge and occusync and indeed our own Taranis, JR and Spektrum that are much more secure setups.
