I have a question about the Wi-Fi signal power indicator at the top of the DJI GO 4 screen (curved bars, AC - RC connection) .

It indicates up to 4 levels. At what level should one begin to be  concerned? I have noticed that at some locations, when I get beyond 200  meters or so it drops from 4 bars to 3 bars. Should I keep going or is it time  to turn back? What level is safe?

I have seen some super-long-distance you-tube videos with the indicator down to one bar.  I am not trying to set any records myself, just trying  to fly out a ways while still being careful.
