I would like to connect two buildings together (house/shop). They are about 400-500 feet apart. To my knowledge, this would require some pro-sumer or pro level gear to accomplish this. A directional antennae on both sides is a obvious choice, but what size/power of one do I need? What is the max speed I could accomplish? This would be a bridge type of setup. Prices seem to be all over the place when you move out of standard home gear.

Because this is dealing with potentially pro level gear, I think SF would have many more knowledgeable people in this area. This would fall under wireless bridges of close buildings or other outdoor setups.

I saw this, but it seem to be for any distance. Wireless network between buildings

This is on SU originally:

And discussed on MSO:

EDIT: It would be very nice to have a POE type setup to eliminate having to run external power to the antennae.

It was asked at SU orginaly, but SF has brought many more useful answers as more people here know this hardware much better. – Troggy Oct 22 '09 at 18:41

You can do this with a variety of devices, depending on how "DIY" you want to get. You're trading, ultimately, your time for the purchase price.

I've used the Ubiquiti "Bullet" radios for such a link, but in those cases we were replacing existing APs and antennas were already in place. For what you're looking for, provided it's a clean line of sight between the buildings, you could probably get by with a couple of Ubiquiti NanoStation Loco APs, which have integrated antennas, are weatherproof, and are only about $50.00 / ea. I haven't used the NanoStation Loco APs personally, but I know they run the same Linux distro as the Bullet radios and I was very pleased with the OS stack running there (open access to a command prompt if you so desire, and a nice web interface available stock).

Be aware that the Ubiquiti devices use passive power over Ethernet, which is different than "traditional" 802.3af. Ubiquiti sells a "POE-15" power over Ethernet injector for their devices that's about $15.00, and it's worth it if you don't already have gear to do passive PoE injection.

A POE power setup would be much more convienent and desired over a tranditional power setup. – Troggy Aug 31 '09 at 19:39
PoE is very nice indeed. Don't forget that you need a lightning arrestor on any cable that leaves the building, too. If you go with an AP like those Ubiquiti devices, which would just have an Ethernet cable (w/ power) feeding them, be sure to use a cat 5 lightning arrestor or you run the risk of lightning making it back to your Ethernet switch (or further) if you take a strike on the AP. – Evan Anderson Aug 31 '09 at 22:00
I selected this as the answer for now, but I am still open to any suggestions or hardware recommendations. – Troggy Oct 8 '09 at 22:31

I have similar setup at my house. The bridge is between the house and the shop. The distance is 550 feet clear line of sight. I am using the Engenius EOC-3320-EXT AP/Bridge radios. I have one setup as a access point and one setup as a bridge unit. Connection speed is 54meg 801.11g. The radios are POE and outdoor rated. The radios came with POE injectors.

The EOC-3320-EXT has been discontinued. The replacement is EOC-3610S-EXT. I have not tried these radios. I gave about $150.00 each for the 3220's. They have been in operation for about 9 months and no problems.

The manual states you can setup the radio as a 802.11 repeater. I was never able to get the repeater to work even with the help of Engenius tech support.


Some people have had success with this:


My sister & husband live up on a mountain outside of Golden, CO and get decent internet by bouncing a signal off relays. They use a flat antenna which looks like the one I found here by a Google search, though I don't know if it's the same brand:


This was a worthy contribution from SU:

This is different from what you asked, but another way to solve the same problem:

It can travel 1.4 km, so the distance to your shop is fine.

"stable 10Mbps full duplex data rate"

"Material for one Ronja 10M Metropolis device costs 2000CZK [110 USD] and building the device takes 70 hours."

The connection degrades in fog or smoke, of course.
