3.5 MILE WIRELESS BRIDGE

Hello, I am trying to figure out how to make a bridge from my house to
a distant friend's house (about 3.5 miles straight line) The purpose of
this bridge would be so that I could subscribe to dsl at his house
which is right about where dsl service ends. I have direcway and I hate
it. Anyway our properties are roughly at the same height, my elevation
is about 1600, his is about 1560, and there is a valley between our
houses that dips to 1300. I am planning on putting a 19dbi directional
grid antenna on a 5' tripod on my roof to make it about 45' off the
ground and connect it to a WAP11 which would then hook to my server, on
his end I am going to put the same hook up on the side of a 75' silo
and hook it to the dsl modem. I haven't climbed up on the roof yet, but
I am sure that I have a clear line of sight.

The moral of my previous paragraph is, would it be possible to
construct this bridge and it actually work, and does anyone have any
ideas on any eaiser way to get this done? Also the WAP11's have two
antennas so would it be possible to hook the directional grid antenna
to one side to send the signal to my house and connect an omni or
something to the other to send the signal to his house, or would this
just slow it down by making it a point-multi point? Thanks

This might just work. The WAP11's aren't really made for this sort of
use, but plenty of people have made them do things they shouldn't. As
for the two antenna types on one AP, that's getting creative, probably
won't work the way you're thinking. If you're taking the DSL input,
running it into a WAP11 and then to the directional panel antenna for
output, your friend could probably get a decent signal off the side
lobes. The fact that you seem to have clear line of sight means this
project has a high degree of feasibility even if it means a little
experimentation on your part. Keep the amount of coax cable to an
absolute minimum. The more coax, the less signal. If you have any
outdoor connections, waterproof the holy shit out of them. Then
waterproof them some more. Myself, I like gear made for the outdoors,
usually comes with POE and coax doesn't enter into the equation.

Keep in mind when you've climbed to the top of something like a 75' silo
and you hear some weird sounds, check to see if maybe your knees are
making contact at irregular intervals.

I didn't quite get this statement.

He is talking about your knees knocking because of the height!

The only thing I would say is that WAP11 2.2's worked very badly for the
longer link, i'm guessing it's a timing thing but when replaced with
version 1 it all worked fine.  Your mileage may vary and they might have
fixed it by now anyway.

Do what?  The two antennas are there for diversity reception.  When you
use an external antenna, use just one and configure accordingly in the
config so that the chosen antenna is both send/receive.

You can do it for less than $100

Apparently these guys use the D-Link 802.11g access points in a
bridging mode. Is bridging mode included with these access points
normally, or does the firmware inside need to be reprogrammed for
bridging mode? I've got an older DI-614+ but don't remember
seeing a bridging mode in its setup.

Dunno you'd have to look but plenty of very cheap, e.g. sub $50 AP's
will do bridging mode.

Re: 3.5 MILE WIRELESS BRIDGE


I have a similar setup between my office and home - approx 7/10th of a
mile.
However, direct line of sight is not accomplished due to quite a few
trees.
I am experiencing varying success with bandwidth speed.  It seems to
vary from
125 to 900 kbps.  Most often at the low end.  Any thoughts on how to
stabilize speed at the 900 kbps high end?
 I am transmitting a signal from my office, using a flat panel antenna
(Model FP19W 19 dbi gain 2150m-2700 mhz), to my house
At my house I have a similar flat panel antenna that flows to a bridge
that flows to a Linksys Workgroup Switch EZXS55W
Version 3 that flows to DLink Access Point DWL 2100AP.
In my Dell Inspiron 9200 laptop I have an internal Intel ProWirless LAN

2100 3A Mini PCI Adapter.  When I use the internal wireless I seem to
consistantly generate bandwidth speeds of 140 to 150 Kbps.  However,
when I disable the interenal wireless and plug in my son's Netgear 54
Mbps USB 2.0 wireless adapter it generates bandwidth speeds of
900+Kbps. Thinking that it was a problem with my internal wireless I
went out and bought the same Netgear wireless device my son was using.
When I fired it up it would generate speeds of 140Kbps.
Any thoughts or comments?????????????????????
