That's an interesting thought ... Our smart meters use ZigBee SE protocol, which runs at 2.4GHz. And of course every house nearby is equipped with that.
Here's an interesting link: https://support.metageek.com/hc/en-us/articles/203845040-ZigBee-and-WiFi-Coexistence
Yes, the 2.4GHz channels seem to differ depending on the device.
I have the drone RC units set up to trigger my studio flash units wirelessly using a Paul Buff CyberCommander (Elsewhere on this forum.).
I happened to have the channels on the same frequency although the channel numbers were different. I was getting misfires and found out that I was sharing the frequency by accident from the table below. Channel 13 on the CyberCommander is the same frequency as channel 19 on the P4 RC box.
CyberCommander channel, followed by Frequency (GHz)
1, 2.427
2, 2.429
3, 2.431
4, 2.433
5, 2.435
6, 2.437
7, 2.439
8, 2.441
9, 2.443
10, 2.445
11, 2.447
12, 2.449
13, 2.451
14, 2.453
15, 2.455
16, 2.457
DJI Phantom P4 channel followed by Lower, Center Frequency, and Upper Frequency band (GHz):
13, 2.381, 2.391, 2.396
14, 2.391, 2.401, 2.406
15, 2.401, 2.411, 2.416
16, 2.411, 2.421, 2.426
17, 2.421, 2.431, 2.436
18, 2.431, 2.441, 2.446
19, 2.441, 2.451, 2.456
20, 2.451, 2.461, 2.466
There appears to be some wide overlap of the channels in DJI's setup too so one has to be careful with them.
