Hi Everyone,
I have two clients who are trying to expand their internet to another
building - one case, from their mobile office to their house on the same
property up on a hill, maybe 400 feet away, with trees in between. My other
case is similar, going from their house to their workshop, separated by the
same distance and obstacles... To share their cable/DSL, I've already tried
an upper-level $300 Belkin, I believe it was, wi-fi router which almost made
it (probably 75' from getting the lowest possible signal) and am looking for
suggestions. Wireless must be the only way to go and I'm guessing they'd
need some sort of an outdoor access point to get the best range? Speed isn't
as important as range since it's only to be used for Internet... If they can
get 2-5mb, I'm sure that'd be plenty... I'm sure there are many similar
posts out there but I can't find any as I'm not sure of the best
wording/terminology to search for... If someone could assist, or point me to
a similar posting, I'd be very appreciative... I do know cat 5e and
802.11b/g networking, just haven't been asked to do it with such a large
distance...
Many thanks,
Scott

Look at the Tranzeo equipment at http://shop.electro-comm.com/ac/Prod...=60399&view=19
Much cheaper than what you're playing with, will go much, much, much
further than what you need. Run a cat5 cable outside, mount the radio,
set them up, you're in business.
Are you using the router antennas or have you fitted some external gain
antennas and what type(s).
I have used a couple of home made biquads which have a gain of about 10dB
and we have been getting reliable 6 Mbs links over some 300 odd yards with
intervening trees and wooden building. The AP is a DLink 604T and the
clients are simple Prism based USB adaptors mounted on the antenna. The AP
feeds a 10 dBi Omni with 3 yards of LMR400 coax so feedline losses are quite
low. We have even managed to reduce the AP output to about 25% from the
nominal 30 mw and still have a good margin even in a rainstorm. Provided you
lock the system down to lower speeds, the problems associated with
multipathing with reflections and not true LOS do not appear to be
significant. If it is only extending the DSL link, then even a 1 Mbs rate is
more than adequate.

Like I said, I am doing 6 Mbs easily. Even with a 1 Mbs rate, can you read a
web page that fast!
There are sections in our area that can run gigabit to the internet via
cable, now there is a real problem!
(all said tongue in cheek)

Try a CISCO Aironet 350 wireless outdoor bridge. ($400-$500)
a.. High-speed (11-Mbps), high-power (100-mW) radios, delivering
building-to-building links of up to 25 miles (40.2 km)
b.. A metal case for durability and plenum rating and an extended
operating temperature rating for harsh environments
c.. Supports both point-to-point and point-to-multipoint configurations
d.. Broad range of supported antennas
e.. Simplified installation, improved performance, and upgradeable
firmware, ensuring investment protection http://www.cisco.com/en/US/products/...s/ps458/ps460/

Thanks everyone, for your advice - it's exactly what I'm looking for! The
Tranzeo looks just up their alley... I couldn't get enough info from their
website though as far as distance... Is it safe to assume 400-500 ft will
more than work? What exactly defines "line of sight"? If there are trees,
etc., blocking point "A" from "B", will it not work? Assuming all else
works, will the clients connect the same as if it was a wireless network,
meaning a wireless network will show up, and bam, they just connect to it?
So if they already have a regular router/cheap access point for Point "A",
this piece of equipment plugged into one of the ethernet ports and wireless
cards on point "B", they'd be all set?
Thanks again for any info,
Scott

Line of sight means "Can you actually see it?" If there are trees,
buildings, etc. in the way, expect problems. One maple tree may not be
too bad, but a wooded lot ... problems. If you can't actually see the
other building, figure out a way to where you can. What about from the
rooftops? What if you had a 30' mast from Radio Shack on one or both of
the buildings rooftops?
If you want to get just one product to use at one end, I'd recommend
getting an access point to aim at the other building, so multiple
clients can connect. But if they're in a glass and steel cage, I'd put
an access point aiming at the building and a Tranzeo client bridge at
the other end. Run that into the building and hook it up to a router.
As for distance, with proper line of sight and not too much radio noise
in the area, they'll work for miles. As in maybe 15 miles. I don't have
any need for that much distance (yet) but I've got smartBridges (very
similar to Tranzeo, just more expensive and maybe not as good) running
at two to three miles with rock solid connections.
Don't forget to set up security. Since these are 802.11b, the security
isn't that great, but it's a lot better than nothing. Set up encryption
and MAC filtering. There'll be people post that this is very easy to
break, but it's only very easy if you're well versed in wireless stuff,
most people aren't.
Connecting two buildings about 400ft away?
