Video through mobile phone network

“Upgrading the flight range”

To broadcast video, the most known connection is WiFi, but its range is very low.
A very good alternative is to broadcast through the 4G/LTE or 3G cell phone band, which uses the antennas from several telecommunications companies all around the world.
With this in mind, the plane could fly as far as the battery lets him, maybe from coast to coast of Spain.
A SIM card system must be implemented with the transmitter of the video, the signal exiting the camera, and it needs a mobile data plan with a company operating in the country where it is going to fly.
With a simple approach between mobile network providers, the cost of broadcasting Full HD during an hour via satellite to the ground is equal to: 15€.

There is someone who has already implemented this idea into a camera, as it was shown before, in the camera option number 1. The disadvantage is that the whole system (app included) costs 400 €.
