cI want to add wifi video transmission to my copters. I already have a Navio and I’m looking into an Edge for other copters.
But as far as I understand it it is not legal in Germany to use 5.x (<5.726) GHz wifi onboard of a flying vehicle but only >5.725 GHz with not more than 25 mW (which should be the case in all countries of the EU).
This is far less than the 27dB Edge (and DJI systems) report in their data sheet.
What is the transmission distance with 25 mW?
Do I miss something?
