The DJI Mavic Air is arguable the best drone out there. It is highly portable (due to the fact that it is foldable), extremely versatile and the image/video quality is very good (4K!).
The ‘Foldable 4K Drone’ – as DJI is selling this – promises limitless exploration. Shots from very high up in the sky are breathtaking. On the DJI website, the manufacturer promises the DJI Mavic Air can go 2km far. They say:
“Unobstructed, free of interference, when FCC compliant. The max transmission distance is 2km when CE compliant.”
Furthermore, the site also mentions: “A new Wi-Fi video transmission system supports dual frequency bands of 2.4/5.8GHz and a 720p live view from up to 4km away.”

So in general, the drone should be able to get at least 2km distance. Many people however complain about DJI Mavic Air range issues:
– Video stutter when travelling too far
– Transmission error of live video
– Interference detected error message on the controller, even when there is no interference
– Choppy live video when flying high or far away

How to resolve live video range problems on the DJI Mavic Air is the key question.

Solution 1:
The first solution is quite obvious, but often overlooked. Make sure that you disable any object/source that can interfere with your Mavic Air or other DJI drone.
People have reported that disabling Bluetooth on their iPhone or Android, as well as their Apple Watch helped to extend the range and remove the live video hiccups they experienced.
Other problems can be: nearby wireless access points, such as routers.

Solution 2:
Another solution can be to replace the cable of your DJI remote controller. The default cable that comes with your drone is short and is being pushed and bend so that the signal is not optimal. This can also be a cause of interference on your Mavic Air.
The solution here, again, is rather straightforward. Remove the existing small black cable on the left side of your drone. Now take a good cable (for example: the genuine iPhone cable, or a cable from a well-known brand) and connect it to the full 2.0 USB on the bottom of the controller.

Now try again to fly your drone. You should experience a whole better flying trip where the interference is no longer there or at least minimised.
