Back in the Alvarion days we had a customer in south FL with well over 1000 CPE using UNII-2 bands with DFS via the BreezeMAX Extreme product. They ran only QAM16 or higher connections and we able to achieve that with high reliability in the dense suburban areas up to about 3 miles. The low noise floor and 2x2 MIMO was a key factor in getting their excellent link budgets. So the idea that mid-5GHz is not good for BWA is a myth.

A 30dB dish with a 0dB radio on it will easily go 4-5 miles. Or put a 34dB dish on with a -4dB radio if you want more gain.

A good explanation is at Wikipedia strange enough... http://en.wikipedia.org/wiki/U-NII People running equipment in frequencies at a power level higher than intended is the issue. Also, the 5470-5725 band requires DFS. Actually, so does 5.25-5.35, as of 2004 or so. It didn't originally, but when they added the 5.47-5.725 band, which needs DFS, they added the requirement to the original U-NII-2A band. So 15.407(h)(2) Radar Detection Function of Dynamic Frequency Selection (DFS).

The power level down there is adequate for some applications, like half-mile links. Lots of old Motorola PTP-400s are legally pumping +5 to +9 dBm into panels... one urban path is working over 2 miles, though we're replacing it.

Date: Sun, Feb 9, 2014 11:53 AM I'm going to agree with others... Running outside legal limits doesn't look good to the FCC, and it sounds like you are definitely running outside the limits since you are whining about the ability to run your radios in a mode which seems to have no use than to exceed the limits. I will also add that if you're running all your radios hotter than they should be that your nose floor problem is most likely self inflicted. My experience over the years is that radios are designed to run at a specific tx power and if you're exceeding it you get a lot of out of channel bleed over. Even if the radios don't do this you are introducing far more rf than is likely needed causing an overall rising of the noise floor. Please don't interpret everyone's ire incorrectly. We've just all either dealt with an operator like you are now or have been an operator like you are now. And right now we're trying to gain credibility with the FCC which is hard to do when some operators are flagrantly breaking the rules. Which makes us a bit grumpy. I'm sure some of your neighbors out there would love to help you better understand what you are doing to yourself and help you improve your operations which will in turn improve your quality of service. Heck, I'd drive over there for a weekend if my schedule wasn't so packed. In any case please ask for help in appropriate spots and let us help you reap the rewards of a correctly and legally operating network.

Since we are primarily Ubiquiti equipment I can only speak from that platform. First the latest firmware update removes compliance test which for about 40% of our equipment deployed would render them unusable since 5735 - 5840 runs at - 50dBm or higher noise levels in our area, Second is new product released only supports 5735 - 5840. Seems like DFS is such a pain that manufacturers do not want to mess with it. Case in point the new NanoBeam M series only support 5725-5850 for USA. Worldwide version which we are not allowed to buy or deploy supports 5170-5875. Seems the only alternative is to go with licensed P2MP which makes more money for the FCC and drives the cost of wireless internet up for both wisps and consumers. -- Arthur Stephens Senior Networking Technician Ptera Inc.
