That's not the way I understand digital radio transmissions. They can all get the same number of bit transitions per cycle. That being the case, you will get 2.67x more maximum on a 2.4G link than a 900M link and about 6.4x more on a 5.8G than 900M.

Try them in a clean environment, like your work area. What is the maximum throughput you can get on a 900MHz link when your SNR is 80 or 90. I don't think you will ever see it doing air rates of 100M.

900 will move the same amount as data as 2.4, 3.65 and 5 GHz with all else being the same.

If your throughput is low, you have too little signal for the noise you're seeing.

I don't have anything to compare it to other than Tranzeo 900, but I have had decent results with it. It obviously won't push the throughput that 5G or even 2.4G will, even with the same channel sizes, but UBNT salvaged most of my 900 customers when the Tranzeo gear started running into problems.

    MHz system was junk had a poor RF environment.

    98% of our terrain is heavily wooded. Ubiquiti 900 is junk (but
    their other products perform quite well when they can be used).
    Cambium 900 is better. Out limited experience with whitespace has
    been good. All of these technologies have very low bandwidth.

        What are you guys deploying lately in heavily wooded areas?
        We've used both Cambium pmp320 Wimax and UBNT M900, with mixed
        results on both. We just put up a 130ft tower in a heavily
        wooded river valley area, leaning towards the UBNT solution
        but hate putting money into something I'm not really satisfied
        with.
