Wait , if the phone connects to the controller via WiFi, the controller acts like a router from the phone to the drone right? Meaning that the range would be unaffected?
Your phone connects to the controller with a cable. It passes commands from the DJI Go App to the controller using a USB connection. The controller can modify these commands, e.g; when the sticks are moved.
The controller connects to the drone using WiFi, enhanced WiFi or OccuSync - They are all variations of WiFi with different types of modulation and spectrum use to improve the performance.
The drone sends video and flight telemetry data to the controller which might display some data (depending on the controller type) and the controller sends this data to the phone using the USB link where the DJI Go app displays the video data and telemetry data on it's display.
It is possible to use a phone/tablet (running the DJI Go app) without the controller by using the phone WiFi but range is very restricted due to the weak, non-directional signal of the phone's WiFi.
Most people seem not to bother with this 'feature'.
