Ubiquiti claims 150 megs of TCP/IP throughput, which is possible if you add upload and download as is common in the unlicensed world.
I couldn't tell from any documentation whether they were 20 MHz or 40 MHz. The FCC certification wasn't overly clear, but I think it can do both. I don't see any reason why something can't do full data rate at 15 miles. My Orthogon does full data rate over 18 miles. I haven't tested my MT's since I got boards that can handle that much speed. Someone has to alpha and beta test the gear. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------- From: "Michael Baird" <m...@tc3net.com> Sent: Tuesday, August 18, 2009 8:20 PM To: "WISPA General List" <wireless@wispa.org> Subject: Re: [WISPA] Bullet M5 HP > Sorry dude, I love Ubiquity, but 100 subs on a atheros system on a chip > at 12/6 -> Impossible. > 130 Mbps throughput on a 100 mb ethernet port -> Impossible. > 130 Mbps at 15 miles when full modulation at 40 mhz w/2 antennas is 130 > Mbps is ->Impossible. > YOU haven't tested any of the new UBNT gear, so your suppositions are -> > Impossible. > > Regards > Michael Baird >> I never said you had to believe me.
