What equipment needed to bridge 1 mile wireless network

Posted on 2011-09-24
Last Modified: 2012-05-12
We have two buildings, about 1 mile apart.  From the roof of one building we can see the roof of the other one, and I've heard of bridges between facilities several miles apart, so I'm sure it can be done.  I've done smaller wireless bridges in the past, but never something that needed to be as reliable as this, for a business.

I'm wondering what products I would need to get it done.  We have line of sight between the two buildings, so what access points and antennas (i would think directional antennas?) would I need?  Preferably something that has a signal strength meter so we can fine-tune the antennas.

What think/suggest?

Don't want to pay for an enterprise ($2000+) solution, but I don't want someone to recommend that I use Linksys WRT54Gs either :)

Im using Linksys E4200,,

But the cons are USB port supports storage but not printers and also there is no BitTorrent client..
But any ways i will strongly suggest this..

None of the Wifi equipment has that kind of range except 802.11a in the 3.7GHz band.  There is a lot of regular point to point microwave equipment that will do it.  That's what used to carry long distance for phone companies and industrial connections.  MCI got it's start with microwave communications for the railroads.  Motorola makes point to point ethernet over microwave but I didn't see any prices listed.  It also might require licensing to use the RF band.

Can someone make a suggestion?
I've seen WIFI equipment with a range of 3 miles with the right directional antenna, so I know they're out there

This is probably what you are talking about:  They also have an antenna available.  This is a point to point connection or bridge which is what you would want.  Really, the only thing WiFi about it is that they are using one of the WiFi frequencies so you don't have to get a license to operate it.

For the record, I appreciate everyone's comments, but I went with Ubiquiti in the end.  The NanoBridge or the Ubiquiti Rocket M5 paired with Rocket Dish... both would appear to work well

Thanks for all the comments.
For the record, there are WIFI products that have 45km range and well above.

That is a very misleading statement.  The product you picked is WiFi only in the frequency band they use, same as the Crane product.  It can't be used as a WiFi access point like a standard WiFi router.  It is strictly a point to point connection and requires two of them, one on each end.
