Connecting two fairly close buildings

Well no it wouldn't. IF you know what your doing the lag would be in the 1-3 ms range. Not what I would consider extremely high anyway.

Ok, I've found another option that I am curious if anyone here is familiar with:

Patton 2168

This product supposedly will extend your ethernet up to 1 mile with simple cat 5 cable. The product costs about $550 at CDW. This would definetely be a nice option if indeed it works. Any comments?

I know that looks have no bearing on performance, but that thing looks like it timewarped right out of 1983.

avoid like those things like the plague. very unreliable/flaky.

If you want to go that route look into Cisco Long Reach Ethernet (LRE). But even then your running the risk with the copper cable in the ground (might even be against code depending on your area)

PUfreak13, bury the fiber. Just do it. It's expensive up front but you'll really be happy you did. Make sure they trench conduit and pull a bunch of fibers so you have some room to grow. Your company owns buildings and the land in between, they can spring for it.

Fibre..

Easiest, safest, and cleanest. If this is to be a backbone between two sites, I'm not sure why there is even a discussion...

If it were for "my company" it wouldn't be "a discussion", but its not. My home is the building that is without internet and I am trying to connect to a business that does (happens to be my dad's business), so there would be no company money involved. I am just trying to get internet at my house that isn't slower than dirt. I just don't have 2 grand lying around to do it.

Sorry, I guess I should clarify better.

 

[spidey07]

well you could try the range extenders or tut devices or locate some Cisco LRE on ebay.

Just make sure you use lightning arresters/entry protection on the cat5. don't want any fires and what not.

Has anybody had an experience with "Non Line-of-Sight Antenna?

I'm looking to install a very similar link and it's an intriguing option.

 

[canadageek]

try tranzeo
we use their stuff at work (a small ISP in central BC, Canada)
its LOS, and has a throughput of 11MB... 2.4 Ghz, and it should give ya plenty of range....
you might even be able to get some other people in your area connected...
its not like your business uses all that bandwidth, all the time, right?

this looks like what you need...the 6015 all-in-one point to point....$434 canadian
cheaper than fibre, anyway
hope it helps,
cheers

Ok, last question and I'll stop bugging you guys. I've found a non-point-to-point wireless product that seams pretty promising. The Trango M900
It goes through trees and has a range of up to 3 miles which is more than enough than I need. Also, it acts as a point-to-multipoint network so I could connect a couple of my neighbors as well. Let me know your thoughts on this product. Thanks again!

 

[canadageek]

3MB throughput...realistically, that will be much, much lower....

If you're really against investing in the fiber and all the hassle, contractor, permits,etc, then take a chance and buy this kit.


Non Line of Site Wirelss Bridge Kit

Non-Line-Of-Sight Wireless Bridge Bundle. Bridges two points up to 1 mile*, regardless of tree obstructions.

This bundle includes two Linksys WAP11 radios, two 17dBi gain non-line-of-sight antennas (mounting hardware included), two 40-foot outdoor cables, two lightning arrestors, and two 10-foot indoor cables (50 feet of coax total on both sides of your bridge).

* Our distance numbers are conservative. Distances are based on direct line of sight in most real world situations. Greater distances are possible but obstructions, weather, interference, etc. can have an effect on performance.

You can get two wap11s or even two wet11s. I saw wap11s on sale at Newegg for 15 bucks each after rebates last week. I picked them up from Amazon for 25 bucks each after rebate a month or so ago. Then get two 24db antennas (they go for something like 50 bucks each). You will have to have the access points close to the antennas because of db losses in long cable runs. This might require a weatherproof box if you mount the antenna on a pole, say. You will have to aim carefully as these antennas have a fairly narrow gain pattern. Your total cost would be two antennas and two wap11s, something under $200. And maybe some more for a little masting at one or both ends. Will it work? It's worth a try. I'd say probably because the db gain is something like 50 db (two times 24 is 48). 50 db gain equals a power gain of 100,000. In your case you have the equivalent of a boost to the equivalent of 3,000 watts from the measely 30 mw in those access points. I would be surprised if you weren't able to have a solid connection, despite the foliage unless it was very thick, in which case some pruning might do the trick. And latency will not be a problem at that distance. I would definitely try that route before spending a few grand on putting in fiber in the ground.

If it worked like that. Unfortunately it does not.

 

[cparker]

Why wouldn't it? Gain is gain.
