I apologize if this is not the correct Forum for this question....
I was a Network Administrator for 40+ years for Lockheed, Raytheon and Qualcomm so I know a...bit...about WiFi. Had to when seven and eight-figure Exec's couldn't connect to a wireless network.
WiFi. I know it's range limitations regardless of Bandwidth. And yet I keep seeing it popup within Specs for Drones. To wit, the DJ Air2S:
Operating Frequency
2.4 GHz
5.8 GHz
Wi-Fi Transmitter Power (EIRP)
2.400-2.4835 GHz: < 23 dBm (FCC), < 20 dBm (CE/SRRC/MIC)
5.150-5.250 GHz: < 23 dBm (FCC/CE/SRRC/MIC)
5.725-5.850 GHz: < 23 dBm (FCC/SRRC), < 14 dBm (CE)
This cannot refer to the availability of nearby wireless accessibility as the range just is not there and anyone with half a brain is (hopefully) going to have their WiFi secured. The only thing I can think of is that either the Drone or the Controller are broadcasting a WiFi signal while the other receives same and even then how it's managing to do so over the ranges of flight escapes me. Cell Towers are out, not part of the equation.
I was under the impression that the only time WiFi was necessary was to connect the App to the Drone but the above specs have thrown me. I am new to all of this so any input is greatly appreciated!
Best,
Lyman
