Wireless Wire RBwAPG-60ad Kit behind windows experience

Hi,
we are looking at the “Wireless Wire RBwAPG-60ad Kit” and like it a lot.

We need to bridge 30m outside from a ground floor office to a first level office.

But on the box on the back, it states “penetrates some windows, depending on material”, which is a bit of a concern, given that we may not mount anything on the outside of our walls, thus the sender and receive have to be behind our double-glass windows. Does anyone have experience with the kit being behind windows?
What impact would that have on the signal?

Thanks!

Of course it depends on the speed/throughput you expect, but you will likely be very disappointed if you go for a “behind a glass” solution, 60 GHz can be blocked by even medium (let alone heavy) rain (and that is essentially why there is the backup, slow 5GHz link), if your windows are single layer (very old) it may work, but if your windows are modern/several layer glass, likely you won’t get a good connection or a connection at all, see:

@jaclaz: thank you for your input and the link.
Ok, so 60GHz is nothing for us. We have double layered windows. And if we have around 300mbit/s (can be a bit more if the price is not too far appart - to make it future prove) that is enough.

I also went outside and “measured” the 2.5 and 5GHz sent by the Asus router. I get about half way to the next building. Is there a dual band product, that would be suitable.

Any recommendations?

AFAICU, the frequences are linked to both “penetration” and “data transfer” (for different reasons), so:
2.4 GHz, high penetration, slow data (and more likely interferences)
5.0 GHz, low penetration, medium data (and possible issues with radar channels detection)
60 GHz, nearly no penetration, fast data

Are you really-really sure-sure that you cannot place something outside, on the window sill?

You could try with a couple of these:

(inside, at the windows glass) and see what you can achieve, and if it doesn’t work, see if you can drill a hole foe a normal ethernet cable or if one of the flat ones can somehow fit.
