In the Tranzeo 5.4ghz band there was no TURBO mode option available. So I guess only 20mhz channels. I was able to get 29mbps UDP on the Tranzeo and about 20mbps TCP.

How much bandwidth can you push in the 5.4 range. Can it use 20mhz cannels or 40 mhz or can you select that? Thanks -----Original Message----- From: Kurt Fankhauser [mailto:[email protected]] Sent: Thursday, March 11, 2010 2:52 PM To: [email protected]; 'WISPA General List' Subject: RE: [WISPA] 5.4 legal ptp radios Just hooked up a Tranzeo link between two buildings using two TR-5A-24's. These models did have the DFS built into them. I set the band to 5.4ghz and there is no other channel selection available. The Tranzeo decides what channel it will be on. And you do not have the ability to set Transmit Power in the wireless configuration page anymore. This is how it works. When the AP radio boots up it starts listening on a random channel. After 60 seconds of not hearing any of the 5.4ghz radar signatures it will then start broadcasting its SSID and then the client will connect. Its kind of annoying at fisrt cause you don't know if you have the AP/Clients configured correctly until at least 60 seconds have gone by but I have gotten used to it now. Now if it detects radar in the 60 second window it will go to the next channel and start the process over again. If it goes through all the channels and they all have radar present the radio will stop searching for clean channels after 30 minutes and then start all over again. The link I set up was about 150 yards so the TR-5A-24's were overkill. But the good thing is under the DFS configuration page you do have the ability to turn your EIRP power down. The Tranzeo will not allow itself to have more EIRP than 1 watt. It knows that it has a 24db antenna and will adjust the radio accordingly. However you can force the power to be less than 1 watt EIRP by setting the Transmit Power Control to MANUAL instead of AUTOMATIC. The link between the two buildings has their Transmit Power Control set at 10dBm which automatically turns the radio output power to -14db. So -14db transmit power plus 24db antenna gain = 10dBm EIRP = 1/100th of a watt :) Even at 1/100th of a watt on this short of a link the signals are still at -55db on each side.

While the radio can do it physically it does not have DFS and has not been approved for use in the US. I hope I am wrong. Any have the FCC doc to show it is OK to use in the US? I have not searched the FCC site for them.

Off the top of my head, I can remember: Tranzeo TR-5A Trango TrangoLINK-45 Radwin 2000 (has mimo as well) Motorola PTP 100, 200, 300, 500, 600 Any others I'm not aware of? Sure would be nice to see more mimo/N radios certified in 5.4.
