Re: Antenna diagram for cAP ac access point

I agree with the above. You can safely assume the pattern is roughly spherical, then take into account all obstacles and absorbtion by your wall. If radiation pattern would be not a 100% sphere, but a little squished to one side, it doesn't mean there is no signal in the back. It just means it is s...
