I travel between Canada and the US often. After reading about the signal differences (pertaining to distance) between FCC and CE, I decided to go with the US standard (FCC). In other words, while in the US, I agreed to set my wi-fi to the FCC standard when it came up on the GO4 application. When in Canada, I choose to cancel/ignore the request to change it back.
As a result, I am able to maintain the 5Ghz signal for greater distance, without degradation of the video feed. I have no scientific data to produce but the differences in video performance were stark imho. We're not talking 2 miles here, I don't need to push it that far...I am talking a very reasonable 3/4th mile to 1-mile distance. FCC all the way in my opinion. I still leave signal selection on auto (2.4 or 5Ghz) whichever is least busy. Obviously, the 5Ghz is where the rubber meets the road.
I am not a "signals communication" expert. I have no idea why each country chose the way it did. Obviously, Canada is 1/10th of the population of the US. So, why the stronger signal is allowed in a more densely populated area??? Perhaps, the stronger signal is needed to project over all the other signal noise? or...the rules were set before a need arose to change them? Got me, ask a signals expert, lol.
I say drones need their own signal type/bandwidth. The UAV/drone location needs to be handled/coordinated by a data processing center (connected to the various air traffic centers). The secure application could verify your type of flying, authorization etc. The drone user could stop worrying about the insane set of rules and simply plan a trip and video/photo the beautiful scenery knowing they won't kill someone flying overhead in a helicopter, airplane. The system would coordinate authorization/timing and override your input if required for safety reasons. All the while, keeping your UAV safe (lowering altitude when required). Come on innovators, you can do this, lol. I lack the code writing experience or I would do it for you.
