Yes U can.

I stand corrected
I wondered if anyone still looked at this thread
I'm trying to remember why I abandoned wds as unsuitable to my use...
I'll have to look it up.
Tomato is cool, I put it on one of my routers once to check it out but, alas I was already using dd-wrt, had trouble finding my way around to some of the features and decided to stick with the familiar.
You seem familiar with tomato can you/it force a two antenna router to use only the right (or left) antenna exclusively ?
Hi hkaye (if you still monitor this thread) "nycwireless pebble" wow that was a cool OS did you know its been/being reworked as Voyage linux now. Pebble was the reason I started down the linux path.
Did your link work out or....?

I simply do WDS/
My pics http://www.digitalhome.ca/forum/album.php?albumid=827
That's an old LOOK TV antenna with a 9dbi dipole for local, This has a wrt54gl inside the box running tomato firmware WDS.

(dd-wrt) which has Ack timing adjustment now.

Check this out...
It's a kit but you can buy the parts individually as per your needs.

That looks very expensive, how long was the payback from the initial investment there?
Ack timing has always been a feature in Tomato Firmware.
In addition to power levels it is also important to know how the 802.11 protocol uses acknowledge for each received frame. If acknowledge is not received the frame is re-transmitted. By default the maximum distance between transmitter and receiver is 1 mile (1.6 km). On longer distances the delay will force retransmissions.
thanks for the pics

The antennas look really nice! Over 5km and good speeds, this is giving me the confidence that my crazy plan just might work!
I've read about the distance being a factor in the wifi protocol. One of the reasons I was impressed with the Bullet products is they have a simple UI that can set the distance the antennas are apart and the software will figure out the rest for the timing.

Over 2 years ago I setup a 5 km backhaul link from my home to my data center. My first attempt was to use two consumer grade linksys GL radios and 24 dBi grid antennas, believe it or not it worked… we had a good signal but we could not figure out at first why the link would run so slow at only 1 Mbit. As it turned out we discovered that once you go over the 2 km limit the acknowledgment timing gets confused and as a result keeps retransmitting the same packets over and over again slowing the whole thing down to a crawl. The DD_WRT firmware at that time had no working way to adjust this...
I then decided to test some professional WISP radios that would allow me to run a 5km backhaul link with lots of speed. I contacted Tranzeo and they were nice enough to ship me some TR-5a radios and 24 inch microwave dish antennas to test. These radios run on 5.2 GHz to 5.8 GHz. I found the 5.8 end of the band to have too much noise and use the 5.2 frequency. The link has been running now solid for 2 years in every type of weather… and not having to pay Rogers or Bell for Internet is the best part of all along with the awesome speed… 20 Mbit up and down and I’m on a private VLAN with the server room from my home.

|JamesK||One thing I noticed in the videos is that the Bullet has a shielded ethernet connector. So, if you're installing one of those, you'll be needing shielded, exterior grade ethernet cable. Working with that stuff is real "fun".|

|hkaye||The calculation to clear it included the fresnel effect. This being a learning experience, I'm sure I'll be surprised with the results. (hopefully it will be a delightful surprise )|

Awesome video, the Bullet is bigger than I thought.
I'm still waiting for the 1000mW Bullet to be in stock. They say available after Dec 15 th. Hopefully in four days I'll get to order these units.

Here are a couple of videos about the Ubiquiti Bullet.
