Wireless link with no LOS??

Hi,

Ok so here is the scene.. I NEED faster internet access at home(I work
from home) but DSL is not available here and does not look like it will be
for quite some time..

I have a friend who is about 500-600 meters away in a straight line who
has DSL so I would like to setup a wireless link between my house and
theirs.. but there is no line of sight becasue of a few trees and houses
in the way.. We would not be able to put masts up high enough to get over
all that.. I will use the highest gain (probably directional) antenna's
that I can..

As far as I know the UK has a max EIRP of 20dB which doesn't sound like all
that much.. From what I have found most AP's have an EIRP of about 15dB so
I guess the highest gain antenna I can use is about 5-6dB without going
way over the 20dB limit.. or am I wrong in that assumption??

Is there any chance that this would have a chance of working??

I know its hard to say becasue there are many factors that could cause it
not to work.. but is there any chance it would work?

Thanks..

Without a line of sight you do not stand a chance. Sorry.

Nope, you got it in one.

Very little. Supply the postcodes of both properties and we can take a
look in multimap.

Unlikely, you'll need to go around by finding other properties to use as
relays.
