So I just read up about the AF11x. I haven't been paying much attention
to this product because I've been busy with other things.
The datasheet claims "best spectral efficiency in class" and "1.2gbps".
Various people on the forum made claims that don't match up with simple
comparisons of spec sheets. Some were UBNT employees, others were just
fanboys.
The actual info on the spec sheets is that you get about 22% less
throughput per channel at the same modulation level and same channel
size as competing products. They claim huge numbers by adding multiple
channels together. You also can't use a full 80mhz channel, so if I
compare to a PTP820C (which actually /can /do 1.2gbps full duplex in
XPIC), the Airfiber 11x is more like 42% less throughput.
So the spec sheet is factually accurate with it's numbers, but the text
narrative is clearly intended to mislead the buyer. Having just
realized this, I'm a bit offended.
It seems the only thing it really has going for it is being very
inexpensive. Like I can get 2 AF11x's for less than one PTP820S with
full speed licenses. So /if /I can get enough channels licensed for 2
XPIC links, then the AF11x is still compelling. And it might mean I can
justify an 11ghz link for a lower volume site than I could otherwise.
They didn't need to lie about it.
