Wifi antennas, which is which ?
(1/2) > >>
BravoV:
At dual bands wifi, say like wifi router that has multiple antennas.

Do they all serve both bands 2.4 and 5 GHz ? Or separated ?

If its separated, how to determine which is which ?

Karlo_Moharic:
Cheap sdr (one that goes up to 5 Ghz) or cheap spectrum analyzer and small antenna
bob225:
There all the same either dual band or tuned on board, the method of operation depends how its setup (MIMO)
PA0PBZ:
I think it differs per manufacturer and model, some are dual band, some are just fake and have the antenna's for one or both bands inside on the pcb, and others… well you get the idea. Are you just curious or is there any practical use for the knowledge?
bob225:
WIFI its a entire subject on its own, and a big can of worms
