A:Answer Discussing wifi interference as a general cause of fly aways and loss of transmission/control in another post, that is the fly in the ointment. You have the mfg's specs which seem to be calculated in vacuums then you have reality! Since the law requires "line of sight" restrictions (and they keep piling on other things!), can you see your drone 500 ft away? And can you afford the fine past that if you can't?
I try to follow regulations but for those who are adventurous, doing a scenario can take your drone to half the max the battery can do then the Return To Home will kick in automatically. I've seen in videos the Anafi do a couple of miles and almost not making it back. Video transmission suffered after 1500 ft (I believe) but she kept going to the limit before returning home . . . just barely. Better hope your telemetry readings are reliable!
DJI's Accu-sync system refines that "wifi" signal to a super wi-fi which can extend those video transmissions considerably at the price of $800+. Maybe the Autel, too. But you pay that price for the privilege. Add the DJI Smart Controller which doubles the price with their proprietary enhancements which probably contributes to the system's efficiency, you can increase the distance . . . again for the price.
Two years from now, the efficacy of even the lowest systems WILL improve possibly reaching out more miles BUT where will the Law be? That is the question. We all want to go faster, higher, farther . . . but will we be allowed? I doubt it.
