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] MIMO antenna cabling...
Why is 10' of cable a bad idea. I am not doing MIMO, but I have cables from 8 to 145' working just fine. And, the real question wasn't about using cables, but do they need to be the same length. Since MIMO is looking for the best signal and/or combining what is sees from reflections/refractions, I would not see that a difference in cable length would make much difference.

The good thing about teh Arc system is that even with teh enclosure it is very affordable compared to other antennas of similar spec. The ARC has almost 40db of isolation between ports, which makes it best of class performance for MIMO. You are looking at about $150, but performance will be very good. Thanks...

Yes you can run a cable through the bottom of enclosure and to the antenna. Works fine. I've done it - think of it as two antenna connections that have no change of water entering because they are inside. No need to even seal them. The ARC panels work very well. Shove a rocket in that enclosure and you will be happy with the results.

Re: [WISPA] MIMO 5.8 GHz panel antennas?
Fred, The Arc Wireless dual pol panel is a great value with embedded genII enclosure. You have to use the enclosure for the mount to screw on to the antenna. You can still use cables to an external radios, its just that your cables are inside the enclosure, and pass thru the case holes. That actually can be a benefit because it adds waterproof protection. The good thing about teh Arc system is that even with teh enclosure it is very affordable compared to other antennas of similar spec. The ARC has almost 40db of isolation between ports, which makes it best of class performance for MIMO. You are looking at about $150, but performance will be very good.

Re: [WISPA] MIMO 5.8 GHz panel antennas?
Fred have you made a good quality link with Mikrotik using N-MiMo I own a set of MT units with R52HN cards that drove me crazy for about 3 weeks. Never made the MiMo work real well with MT. 2- PacWireless dual pol 2 ft dish with MT a both ends 12 miles. Could make them work as 802.11a but the N was very hard to get working right and never got the speeds that I needed. Was told that I had bad dishes or cables and not aligned right by company that I got the setup from after they worked on them for 4 hours one day remotely. Changed the radios to a old set of RadWin radios I had and went to 49MB in 15 seconds. Never got more than 18 meg out of the Mikrotiks. So now I have some extra MT 411ah cards that I will put in a AP somewhere and some R52NH that I don't have time to mess with. I will just use the RADWin stuff for critical links and UBNT stuff for secondary links.

Re: [WISPA] MIMO
That guy needs to do more research. AirGo MIMO is far better then the other MIMO's products. Netgear dumped the majority of its older MIMO in lue of AirGo because of these reasons. Its pure misunderstanding about AirGo mimo not working with old hotspots. I bought a Pre-N card the week they came out and have used it on AP's from Oregon to Texas and back (two differnet routes, 2300 miles each) and never a problem due to my card. A few motels claiming wifi but really just hijacking the connection from the place next door with a repeater was fun. At least he tries to secure your AP with WPA (which has been cracked just like WEP). Its bogus that a card older then `05 will need to be replaced, many are just driver upgradable. The WRT54G was a decent router, till the v5's when they went to crap. He needs to keep up better. And only some MIMO really hogs the spectrum, the same ones that use channel bonding to get 108mbit. Single channel MIMO like single channel 108mbit is clean and follows the 11g rules for backoff when other traffic is around.

Just been doing a bit of work on the Atheros based Netgear WPN824. It's implementation of MIMO seems to work very well and I was wondering if anyone has started production on a NLOS outdoor AP based on MIMO yet. I wouldn't have thought it would be too difficult to attach some pigtails to the Netgear and stick it in an enclosure. Anyone got any thoughts on MIMO? -- No virus found in this outgoing message.
