Re: [WISPA] MIMO antenna cabling...
In MIMO, Dis-similar Cable length to the dual pol feeds CAN be a problem. Both cables should be the exact same length, or as close as you can make them. This should not be a problem for a 10ft cable. Simply crimp the indoor connector first, since ends terminated really close to each other. Have second cable follow the first cable (maybe even zip tie it to it) and then outside cut the second cable at the point where it reaches the first cable's end. It means not totally using pre-made cables, and having to crimp the outdoor connector manually. Use Ezy connectors to ease abilit to crimp cables up on a roof without the need for a soldering iron.

Re: [WISPA] MIMO antenna cabling...
Note: Interference between cards in a case can be a problem, but With MIMO self interference between polarity connectors is less of a problem than with trying to use two seperate radios not MIMO. Let me tell you why I feel this. In theory OFDM for Full modulations needs at minimum 25db isolation between ports. I've seen huge difference in performance using antennas that had 35-40 db isolation between ports compared to 25db. Because of this, when fiorst testing Ubiquiti MIMO I was very concerned about this. I was concerned that a Nano MIMO only had about 16db of isolations between antenna polarities, 19db sector only about 22db isolation, and large sector about 28db isolation between feeds. So, I'd asume the 28db antenna would way out perform the NANO, in regards to polarity isolation, considering JUST a single link. (not considering intference or isolation from other seperate radio links.Obviously the larger antenna has better front to back ratio isolation from other sectors than Nonos that have little.). Any way we recently did tests on a 8 mile Ubiquiti MIMO link, comparing results using each of the three antenna type. (rockets with ext versus Nanos). The goal was to determine whether the NANO could work adequately as a AP sector, IF there were not many APs at that site. The results were Absolutely no difference in performance, regardless of which antenna we used. (again, just talking about polarity isolation, using MIMO on one link, on a clear channel). The Ubiquiti MIMO worked at full capacity even though the isolation between polarities is not very high on a NANO. I was very surprised. I do not know how this will play out StarOS MIMO. The radio system is an ALIX mini-itx and it has 5 radios, It will be very hard to trouble shoot your MIMO link based on MIMO's merit, as with so many radios within the case, it will be really hard to isolate so many cards from each other, to know whether interference is from cards or MIMO polarities. Receiver overload can also be a factor.

Re: [WISPA] IP Space WHOIS Data Update
Depends... You have to prove that you returned your IPs. That could be as easy as a letter or copying a letter previously sent to your upstream to request the SWIP infor removal, or having none of the IPs on the block responding to Pings. Or showing that your BGP routers or ASN are no longer advertizing routes for those IPs. You are not responsible for whether your upstream is responsible. But again, it boils down to proof, and whats the easiest approach to get results. With ARIN, to speed the process, you dot all your Is and cross all your Ts, because ARIN is overly zealous about formalities.

Re: [WISPA] MIMO antenna cabling...
OK... I just visited the forums and saw StarOS has been hard at work adding N Class support. (Better late than never). I stopped paying attention after around Starv3 v1.3.23 or soThinking EOL was near. I just noticed the opposite on the forums with V3- v1.5.15, and even an ALIX specific version. It appears StarOS's implementation is still playing catch up, but exciting to see that their product is evolving. They definately have the talent on staff to evolve their product to a stable product. Wondering if they are working on adding an embedded Spectrum Scanner software for Ncards yet?
