So I used the WiFi app on my cell phone yesterday.
I turned on my controller and left the bird off.
I came up in channel 2.

Then I turned on the bird.
But I didn't see any additional WiFi signals.

Next I turned on the bird only.
I didn't see any activity at all.
So I ask does the bird only transmit on channels above 14 ?

It only using one channel, I think between 1 and 13. The reason you don't see the AC wifi is because it doesn't have an SSID name, it's not a hotspot like the RC is.

Just as wmcvey said, the WiFi signal is available for remote controller so that you could connect your mobile device to it, while there is no that WiFi signal for aircraft.

"while there is no that WiFi signal for aircraft."

Don't they use WiFi to get the video/data back to the controller ?

Think there's something lost in the translation as English is their second language. I think what she is trying to say is you can't connect to the drone's wifi, like you can with the RC. Just use that same wifi app you used and just check your laptop at home if you have one. And you'll see your router, but not the laptop.

I was under the impression there were two separate transmissions, both in the 2.4GHz band.  One was using the WiFi protocol, so it would be visible using a WiFi sniffer app or computer etc.   The other is transmitting on that frequency, but not using WiFi.  There are countless consumer devices transmitting on 2.4GHz, from wireless doorbells to baby monitors to CCTV to name a few.   None of these will show up on WiFi and will typically use a simple analogue transmission to a matched receiver.

First time hearing that ?  The P3S uses wifi (real wifi protocol) for video and telemetry on 2.4GHz. At least on the Standard, as the OP has. On the P3A and P3P that's where the difference is as they use Lightbridge on 2.4GHz band, which is proprietary and not wifi protocol. The real reason the drone's wifi is not picked up on a scanner app is because it's a client, not a hotspot with a SSID. Just try and scan your laptop (with wifi), it won't show. Or your cell phone, won't show up either. Unless you turn on the hotspot in the cell, and then it will.

I stand corrected.  I don't have a Standard.  That is how I thought it worked, I may have confused it with the Advanced/Pro system.  It may have been reinforced by the fact a few pilots report losing video, but still have a strong control signal.

Yes,  because control signal is on 5.8ghz on the Standard.
