[WISPA] Ubiquiti airfiber on the same tower...
Hi All I was wondering what is your experience on Airfiber. In particular my question is if the following scenario could work or not work in your opinion/experience On tower at LocationA there are two Airfiber pointing at the same direction LocationB and LocationC, more or less. On the tower at LocationA, the two airfibers are mounted at let's say 1-2 meters distance (horizontal and vertical) and 10 degrees of difference in the 2 directions LocationB and LocationC. LocationB and LocationC are two other towers both pointing at LocationA. I am wondering if at 24Ghz I could see some interference or not , in this situaitons Thank you in advance -- Ing.

Re: [WISPA] Ubiquiti airfiber on the same tower...
I would expect that her would be some side lobe interference. If they were more like 40 Degrees then you would probably be fine. But 11 is really close. What Kind of distances from A to B and A to C. The closer the better, the further its going to get more tricky.

Re: [WISPA] Ubiquiti airfiber on the same tower...
Presently doing something like this may be a challenge. Theoretically you my be able to get way with it ... if You GPS Sync the radios. Use the one channel on each of the radios (i.e./ run them half-duplex) and depending on your distance, get more than 2 m of separation... Doing something like this could be easier if and when UBNT comes out with firmware that can allow smaller channel size. If you have to do something like this TODAY.. you might consider speaking with Trango about their new 24GHz radios. They will do 1024QAM, and as such more efficient with spectrum, and can have smaller channel sizes. Of-course, channel size will affect throughput.. and the Trango Radios are going to be a bit more expensive.

I am wondering if at 24Ghz I could see some interference or not , in this situaitons No examples to cite yet, but it should be fine to have them both on the tower, so long as they're not using the same frequency. AirFiber uses solid dishes with a very tight beam; the signal should be way down at 10 degrees and a meter's spacing. And the transmitted power output is very low. The only reason I don't think they'd be good on the same frequency is that a bird or raindrops might reflect some signal back towards the tower. -- Fred R.

Re: [WISPA] Ubiquiti airfiber on the same tower...
Depends on how much throughput is needed. You could run half-duplex and use two different frequencies (almost guaranteed to work), or use the same frequencies and just make sure both sides are transmitting and rx on the same frequency.
