Re: WiFi Lab C
Well, let's get this started with something simple and essential then: what are the two most commonly-used frequency bands for WiFi communications, in gigahertz?

Re: WiFi Lab C
My turn then!
I have 2 access points to keep signal strength strong throughout my apartment. However, I am hitting some deadspots when I am between the access points. However, when I remove one of them, no packets get lost. What is likely to be the cause?

Interference between the two access points causing information to get lost in certain locations where they destructively coincide?

At a low level, yes, this is exactly what's happening.RasmitDevkota wrote: ↑November 5th, 2021, 9:50 amInterference between the two access points causing information to get lost in certain locations where they destructively coincide?
What I was sorta looking for is that the access points were on the same channels. Even though we say 2.4 and 5GHz are the frequencies for wifi, it is still pretty generic since the FCC usually allocates a range of frequencies for certain technologies. Disregarding location, for the main types of wifi, there are 14 channels for 2.4GHz (of 5MHz width) and about 70 channels for 5GHz (ranging from 10-80Mhz wide).

I was thinking more in general since interference happens regardless of the wave properties.

Re: WiFi Lab C
(a) 48 MHz (half-wave dipole antenna has length 1/2 the wavelength, and frequency is speed of light divided by wavelength) (b) VHF (which is 30 MHz - 300 MHz)
