I think you missed my point. The same problem exists if I use Nano Stations, or Built-in antenna models. I live in a very noisy inconsistent environment. Its uncertain in which installation cases Dual pol MIMO will work, and which cases it will not. It all depends on spectral availabilty. I always guess wrong, and it takes so much longer to tests ahead of time. I'm spoiled by using Trangos the last 10 years, I'll always continue to look for the equivellent in flexibilty.
The core benefit is to be able to standardize on proceedure and equipment selection. I dont want to use A one day, N the next. Use Mikrotik one day, StarOS the next, Ubiquiti the next. Its to hard to keep a million different parts and systems ready to go for every products line. Its hard predicting which products I'll need stocked, and which products will be most needed for opprotunities that arise in the future. Ubiquity has the promise to offer one platform that can do everything. And it seems to work well, so far. Its certainly price right. The fact that some CPEs have built-in antenna pre-hard configured to which polarity is Chain0 makes this a much bigger problem than I thought. That means that CPEs have already selected which POL will reside on Chain0. (Im not sure which it is, so hypothetically I say chain0 is verticle) That means that if Chain0 is Verticle, that my whole network must be standardized on using Verticle pol as the primary 0-7 antenna. What if at 70% of my pre-existing DSSS sectors Verticle pol has to much noise and cant be used, and I am using Horizontal pol now? My goal is to replace slow DSSS gear with Faster OFDM gear where possible. When the Ubiquiti radios are put in place they'd be forced to first operate on the noisy channel, not the clean channel. Possibly even interfereing with my other sectors at teh cell site. My understanding is that the primary chain does not ever disable itself. Just the secondary channel auto adjusts on or off. I'd be at risk at destroying my sector quality if I upgraded gear to Ubiquiti, if I could not select which chain/pol would be the primary to use. When I upgrade my network from DSSS to OFDM, I do not want to do it with 3 different products. I want to upgrade it with one product that I can adapt to best fit into the pre-existing situation. In many cases, MIMO dual pol will work fine, but in other it simply wont. This is also critical for disaster prevention. What happens if someone else deploys on chain0's pol, and kills it? It takes a truck role to fix it, and customers are lost in the mean time. Sure I could switch from N to A on the fly MAYBE, but maybe not if the noise was to loud and I lost remote access to CPEs. Plus it would take to long to convert. But if I could jsut go tell all teh CPEs to switch which chain/pol was primary, the primary could be moved to the clean channel, and hopefully the new deployer will eventually go away, and free the channel back up for my radios. Having radios auto adjust turning teh second antenna on and off is NOT a good thing for High ARPU SLA/Performance. Everytime modulation changes, or a radio looses packets figuring out of a pol/chain is usable above the noise, packet loss occurs and customers can feel it. I need the flexibilt to turn off a chain if something migrates to poor performance, but that does not help unless I can select which chain to disable. It only helps if I can disable the chain that has noise. This could be a huge problem. BUT... the problem would go away, if we could simply select which chain will operate like the primary, and always stay active. Lets look at this a different way... When I first built my network 10 years ago, there was a reason I selected Trango over Alvarion and Canopy. The others only operated on Verticle pol. 70% of my sector environments only had free spectrum on Horizontal. Trango gave me that flexibilty, to select. I dont ever want to loose that. If using MIMO means I have to give up that flexibilty, the whole purpose of Dual pol is lost. The facts are.... The primary polarity will not always be available everywhere. It needs to be selectable. I dont want to send out a tech with three products, and then to do a scan, and then select which product to use. Thats to encumbersome. MAybe, the reason I'm buying Ubiquiti is not Mimo, but Price? Wouldn't it be easier to just buy one product line? All the vendors are going to be carrying MIMO anyway, thats whats most popular right now.

Why not just deploy the Radios with the antennas, that they are designed to work with ? What is there to be gained by using a 802.11n radio and then 'crippling' it by using some external settings for 'disabling' one of the antenna ports ? If it is interference you are worried about, let the 2x2 radio with Airmax on, take care off it it self. Faisal.
