Here I've used an ordinary cheap 4G smartphone as an FPV cam for my quadcopter drone, so like this the FPV cam is isolated from other systems on the drone, like the Pixhawk flight controller and the Raspberry Pi companion computer so you could for example run the FPV cam on one cellular/mobile network and the telemetry on another, this gives you some redundancy. For more information how to do this you can ask questions in the comments or contact me directly on Telegram @Aeronaught or email - aeronaughty@protonmail.com
I try and help everyone anyway with answers on comments, email and Telegram but if you do this I'll give you priority and more in depth support on Linux, Pixhawk, Mission Planner, QGroundControl, Raspberry Pi, electronics and much more.
