I don't see it being any worse in terms of advertised mb/s/user than the WiMAX everyone has fallen in love with. 200 people on an 18 meg sector? Hardly. Maybe 30.

(1) You don't really have a "noisy" environment if you are able to run a basic Powerstation AP with 100 subs and have it work at all. We are on towers on hilltops that have over 120 antennas (dishes, sectors, omnis) within a 500ft radius from our tower. (2) You aren't shooting 10-15 miles in a point to multi-point configuration (3) Your math doesn't work. 100+ subs on a Powerstation AP (even if it's doing 130Mbps), that's 1.3Mbps per sub. There is no way _every_ speed test is 12Mbps down and 6Mbps up with 100 people connected. (4) How many total customers do you have on wireless? (5) Why doesn't your homepage load (www.spectrasurf.com)? (6) Our ROI using Canopy is 0 days. :) (7) Even one of the lead engineers at Ubiquiti said the product is designed more for countries with little or no internet service "where they will be happy with ISDN speeds". I have a test setup on the way. I will test and report back what the "real" world is on this equipment. ;) Travis Microserv Jayson Baker wrote: MIMO (especially dual-pol) gets you much better performance. Cell phone companies have been doing this for years and years. You're 3dB vs 25dB comment is misleading. UBNT may need a received level of -70dBm to achieve higher speeds... but, so does a Canopy. You can't expect to achieve anything on a Canopy with, say, a -97dBm signal. Furthermore, UBNT will actually link around -95dBm and work, albeit slow. Canopy will say "SCANNING" We have tested these products, and have networks deployed both here in the states and in Costa Rica. You wouldn't think it, but Costa Rica has waaaaaaay more noise than we do here. The government uses 2.4 and 5GHz for random things, people have way overamp'ed equipment, there are a ton of little WISP's, etc. Canopy down there performs as expected... a couple mbps up, a couple mbps down. UBNT MIMO blows it away, especially with AirMax and in a noisy environment. When testing the MIMO you can't just run a single stream, they work best with many streams. We have seen about 130Mbps on a full-duplex on a deployed link, around 15 miles, in a noisy environment. With the PtMP equipment, we see similar results. With the older non-N non-MIMO equipment, we have seen up to 100+ subs on a single PowerStation AP, all getting at least 12Mbps/6Mbps, and latency always under 10ms. I get it, it's a Motorola list. We're on here because we use some of that too. Not much, anymore, because there are much better products out there. I'm sure this will start a flame war, as talk of anything other than Canopy always does, and I don't really care. The equipment is cheap enough, if you want to see it for yourself buy some and put it in. When you see it works as well as we've seen, you, too, can offer your subs 12Mbps for $25/mo and make killer profits. Our ROI on a new install is 1 Day. We make money the day it's installed. And it just works, we never have customers calling to complain. Cheers! On Tue, Aug 18, 2009 at 5:07 PM, Tom DeReggi <wirelessn...@rapiddsl.net>wrote: Yeah, but its misleading garbage specs. Mimo adds very little in noisy environments, where double size channels and both polarities can't be both used based on spectrum availabilty, not to mention specifying gross speed instead of actual speeds. I'm not saying the Ubiquiti isn't a really nice needed product, I'm just saying, in real world use, I'm not certain its faster than Motorola PtMP, including advantage series. (per Mhz wide channel efficiency). Don't forget the 3b SNR required by canopy and the 25db snr required by Ubiquiti for high modulations, which is rarely acheived in PtMP. Remember, a flaky packetlossy link is going to bring TCP down to its knees in throuhgput reduction. The most exciting thing about teh new product is its inferred that there might be a low cost dual pol sector antenna available now?

Much more impressive numbers than Canopy. Matt wrote: Ubiquity has introduced their new product lines, at www.ubnt.com. Looking to take Canopy on. Anything like GPS sync for frequency reuse?
