How does StarOS handle frequency usage for FDX?  Does it require another
channel (and thus another 20 MHz) for FDX operation?

Subject: [WISPA] Lucaya X-4000 radios


Hi all,

I did some performance testing yesterday with the new X-4000 radio units from Lucaya and wanted to share the results. These are the new four radio access point/client/backhaul units from Valemount Networks (the authors of StarOS). The latest versions of the firmware now support full duplex operation. I took two units and configured them for full duplex and started running ftp downloads and the starutil speedtest utility to see what the performance looks like. General results were that the boards will handle 30meg in both directions at the same time. If one end is not pushing at full speed, the other end will do more traffic, and that split seemed to max out at 50meg in one direction and 15-20meg in the other. I didn't get any speeds faster than 50 meg. This was using standard 20mhz channels. 40mhz channels didn't seem to do much better as the CPU was maxed out. I'm curious to see what kind of results could be obtained with 2ghz CPU units on both sides using the 40mhz channels. For a $400 unit, I think this is outstanding performance and they are very versatile. I have several up as backhaul links (in regular HDX mode) pulling 25-30 meg at distances of up to 30 miles. I even have one set running on a 62 mile shot that will pull 10-12 meg consistently. They are also great as 5ghz or 2.4ghz access points. We have one that has three 2.4ghz sectors on it and 120 clients between the three sectors. The board is doing an outstanding job and very clearly outperforms the three RB532/SR2 access points that were on the same three sectors before.

Here is a link to the Lucaya store:  http://www.station-server.com/store/

I have also heard that Streakwave will be carrying this product as well.
To me, this is one of the most exciting items to hit the WISP business since I've been doing wireless. I thought it made sense to share it with everyone.
