Hi all,
I would like to create a wireless lan joining 2 sites that are about 50
meters (150 feet) apart. The problem is that my neightbor has a BIG
parabolic antenna only 50 cm from where I have to put mine, and my signal
has to pass through his antenna (my antenna has to point his antenna, the
other site is in that direction). Should this be a problem?? I will create
interferences in his antenna? He will create on mine?? how many dbi need to
accomplish that?


Thanks

Hi OM,

Think in terms of a narrow beam flash light, a nearby beach umbrella,
and the point you want to illuminate. Will the umbrella cast a shadow
over that point? If so, think how bright the flash light has to be so
that you could read a contract's fine print in the shadow on the other
side.

Hi Map

Why go to all of that expense?

Within any given residential or commercial block, there are many 'dead
(as far as for phone to switch)' phone pairs. Some of these can be
utilized to connect a network between two homes or two offices, or
sometimes between home and office.
Two of my Uncles homes and their offices were connected this way and
they had no troubles from it.

Depending on who your local telco is, it can be nearly
imossible to get them to hook you up to these dry pairs. It used to be
common; then the telcos decided they'd rather not make this kind of
cheap connectivity available to the general public. I believe I've
heard of some people persuading the telco to set them up by saying it
was to be used for an alarm system between the two ends.

Yes, "burglar alarm" and "dry pair" seems to be the set of magic
phrases to use.

I've heard of people using this sort of wire pair, with a couple of
off-the-shelf SDSL modems, to create a very effective medium-haul data
link between buildings a few miles apart.

Your probably right!
I remember one of my Uncles saying that if they replace the cabling
they will be shut down, and may not be as fortunate enough to get
another one.
FWIW - he does pay around $30.00 per year for the use of the several
pairs that they are using. I have no idea what they charged him to
make the connections though. I believe he is using 3 pairs of dead
lines for their connection.
