My thoughts exactly Tom, I just kept thinking just how nice this would be if there was a version with a smaller antenna, 1/5th of the spectrum and 50Mbps guaranteed duplex throughput. The characteristics of this radio limit its use to either backhaul or linking nearby office locations. The price on the other hand is approaching last mile access territory, what we really need is a 24GHz radio with half the antenna size and 1/5th the capacity for half the price.
I can't help feeling that this radio was developed purely from the technology point of view without a lot of marketing input, "make it faster and cheaper" but really what a lot of ISPs need is "make it more reliable and cheaper". The competition at the high end for many ISPs is 100Mbps PON, at the low end it's plain old DSL, many of us just need a solution to deliver several high quality links from a single location to clients 1-4 miles away without wiping ourselves out with self interference. The integrated GPS sync certainly helps but do we need all that capacity for the majority of our links? This is certainly a game changer but UBNT are you listening????? - - - *Olufemi Adalemo* On Tue, Mar 27, 2012 at 5:06 PM, Tom DeReggi <[email protected]>wrote: > Any way you look at it, the UBNT 24Ghz product is a game changer.
