Any way you look at it, the UBNT 24Ghz product is a game changer. Its bringing a price point, that will mass excellerate the adoption of 24Ghz use. At that price, there are 1000s of uses. Its very exciting. Its also a big bonus that it is MIMO, which should give it a good link budget, compared to the methods other technologies use to accommodate dual pol.
What I dont like about it is that it uses to much spectrum and is to fast, which will cause parties to deploy faster speeds than they need, simply because they can, and cause more interference in urban areas, and reduce the number of links in an area. Often people incorrectly think that millimeter is like inteference free. What they forget is the low range is based on Rain fade, but when its not raining the signal goes very far, and reflections can reflect all over the place, even though narrow beamwidth. But there will still be a strong market for other products like SAF. For example, windloading and mounting. I jsut bought a SAF radio for that reason, where the 1ft dish option was preferred. SAF also has 256QAM support, quite a bit more efficient than UBNT's 64QAM limit, allowing high speed in smaller channels, allowing more radios to be colocated at a single site. I think UBNT's marketing is their typical overstated marketing.. Just like AIRMAX 5.8 where they promote as 300mb, when in reallity Dual Pol 20Mhz channels, the common size that can be used, yields more like between 40mb and 80mb depending on link budget and noise floor. So in doing apples to apples comparisons, its important to take that into consideration. For example, a 13mile link just isn't going to happen in my rain zone, but might be doable in the desert. With 2ft dishes, I dare not go over 2-1/4 miles, and still prefer under 1.5m. I believe the UBNT 24 product will also put a hurting on the 60Ghz market.
