Tried flying my mavic mini in the city park today. Only got to about 300 meters before signal interference warning started to appear. My video streams started to cut out. I understand that a city have a lot of airwaves interference from cellular and wifi signals. But I saw video where people flew their drone in the city area at greater height and distance without seemingly losing control. As I understand it, most consumer drone like Phantoms and Mavic pro also use the wifi's 2.4GHz and 5.8GHz for remote control. So is there a way to cut through the interference and let my Mavic Mini fly higher and further in the city?
