Hi, I made two units for a friend to be used to bridge a network over 50mtrs.
Both CPE's in low 5Ghz band, 40Mhz wide channel.
Both units where fit behind double glazed windows and both had to look under a 50 degree towards each other.
Both power settings in default.
Both units where impossible to establish a connection with each other although the signal reading showed high signals.
When one unit had the window opened in front of it the connection immediately was established with good strength, good rates and good CCQ and 25Mb internet traffic was not problem.
Close the window again and association was lost.....
These so called "Thermopane" windows are double glazed with some gas fill and maybe even some coating.
So, can it be that due the angle the signals have to pass the glass, the reflection is such the antenna's won't receive each others signal properly any more?
Of because it is just too much. I mean, one window open but the other side still closed is not a problem?
Or could it be the coating?
Or the gas?
Has anybody experienced the same and has anybody any idea what could be the issue?
Normally the used frequency band should not have such a problem passing through glass isn't it?
I used nanostations for this purpose, but since this is more just wireless technology related imho I ask the question on this forum.
