Wow, i link NetMetal5 very much!
When will you ship it to distributors?
Do you have any test of it, maybe using your 30dBi antenna?
last page of the newsletter has an example test with 802.11ac
Netmetal should have similar speed. The 30dBi antenna will not make it go faster, but farther
Nice. Unfortunately I will never be able to use it. I struggle to find 20mhz clear space let alone 80 
Same issue here
ac is a new protocol that not only is capable of gaining more speeds by the use of the extra channel bandwidth, it also has interference avoiding technology build in and by making use of the 256QAM rate that even on a 20Mhz channel should give you more throughput.
So, even in congested spectrum situations AC will benefit. Maybe not up to the highest level the technology theoretically promises, but still better than a ‘n’ radio in the same situation.
What we really need now is a manufacturer that comes with a good, all in one, 3 chain high gain (+28dBi) antenna. Than we are in wifi walhalla! 
(Well, at least for a while…)
netmetal 5 looks sweet on that dish.
Mostly curious to try out the mAP2n en the deployment possibilities of the CRS108
As far as I understand it, 3rd chain is only really beneficial in PTMP situations (home/office wifi, sector antenna’s). I never see such high gain sector antenna’s and 3 chains I believe is redundant for PTP links as the 3rd chain would never be used. I could be wrong though.
Well, the top high speeds of ‘n’ or ‘ac’ are only achievable in triple spatial streams configurations… you do need a 3rd antenna for that.
Since everybody is looking to transport more and more data day by day while rates are under pressure we all are looking for the most economic high bandwidth backhaul solutions possible. Only 300, 400 or higher Mbps WiFi products can deliver that. So a good all in one 3 chain antenna is definitely something we are waiting for…
What interference avoidance technology is built into the actual Atheros Wave2 Chipsets?
The standard does not claim higher near/far channel rejection than 11n. The vendors do
not provide this numbers …
I must say I haven’t found the article yet that I red some time ago. But what I can remember was that while ac is using 80 or 160 wide channels, within these it will try to communicate with its other radio on only these channels that are free of signals from other ‘legacy’ 20/40Mhz channel using radios.
It sort of ‘bypasses’ these channels to use only the ones with the low noise. And this on a dynamic base.
What I can remember this was one of the mayor advantages of ac if it comes to working in frequency band overlapping circumstances where ac was thus able to choose the best channels available in its spread. Of course this would mean lesser throughput because some spatial stream were rendered ‘not usable’ but since it happened on a dynamic basis these omitted channels would be used again when the alien radio signals would have gone…
Actually it came with a scheme to show that in a 160Mhz spread where two legacy a (or 40Mhz ‘n’) channels within this same spread were used by other radios these channels were just not used by ‘ac’ radio. This would mean a degrease in total maximum throughput for the ‘ac’ setup but the still usable channels were still able to transport considerably more traffic than a ‘n’ (or a ‘a’) radio would be able to. Because it could still use two, three or more usable channels.
Basically in an area where the whole 5Ghz radio spectrum would be used by legacy ‘a’ or ‘n’ channels you could still put several 80 or 160Mhz wide channels in the same region and the ac protocol would still be able to deliver more speed than a ‘n’ would be able to do.
For building backhauls this would be ideal. You could make a 160Mhz bandwidth wide link and if some of the underlying frequencies would see some interferences (at times) these were just not used but the rest of the traffic would still be steered over the other available ‘quiet’ channels.
We all know that interferences at times are very dynamic too. This way if using a 160Mhz wide channel where at times it ‘sees’ interferences on two 40Mhz channels we would still have 2 other 40Mhz channels left to transport our traffic. That is still 200% of what a 40Mhz ‘n’ channel could deliver!
And to be honest, if this would not be the case the whole ‘ac’ history with its high throughputs and ‘the need to have’ factor would be an empty air bubble whatsoever. If it wasn’t able to use the extra wide channels due overlapping/interferences with other legacy 20 or 40Mhz radios ‘ac’ would be almost completely useless in the ‘real’ world… Spectrum is used and stretched to its extend almost everywhere. It would make no sense to design a new protocol that would not come with one or another system to handle the congested spectrum of nowadays…
Tonight when I can find some time I will try again to find that specific document.

Its not the article I’d remember but it comes pretty much in the direction. Its worth reading for everybody that is thinking of deploying ‘ac’ in an already used spectrum. Like many of us WISP i’d presume…
Go google on: “802.11ac co-channel interference” and gets tons of info about 802.11ac and how to deploy and what to guard for. Very interesting reading, before you buy!
It’s 50mW or so. Really weak, but it could be powered from USB port…
it is not really weak - it is normal output power for home AP. Most of devices (laptops, phones etc.) will have similar tx/rx signal strength.
Janis is right it is nice power for home use, I have 951G and first thing I do when is install is to lower power to 12dB is quite enough to covert couple rooms in flat.
I don’t understand why people want high power device in they living or working rooms 
. Just thing using high power device give opportunity much more people to see you signal and my someone of them to try to do something with sniffed packages if have time and resources.
Not always. Imagine that each amplifier has its distortion. Normally more powerful amplifier used at 1/n of its maximum amplification level gives much less distortion than weak amplifier working on its limits.
I would like to know if can i use at NetMetal 5GHz Triple Chain only two chains? Stop one if i do not want.
Yes
It is perfect for such location. Because it is so small you can install 2 mAp on each floor and you have good coverage in the whole building.
