[AusNOG] Ubiquiti Rocket Transceiver pair - which antenna ??

[Darren Moss]

Thanks Ross.

Yes we can do multiple of the same to different transmission points, that's no problem.

The main concern is reliability and latency.

We are looking at 5.8.

Don't need to use licensed spectrum - I have enough of that with STLs.

Cheers

Darren.

If you want "super-reliable" I wouldn't be considering the ISM band. 
Period.

That said, I ran a 3.6km link on 2.4GHz ISM band between my home and office for 12 years with zero dropouts. That was likely helped by:
  (a) being in a regional area with little or no competition in the band at the time

and

  (b) using 28dBi gain antennas to reduce the effect of any other users in the band at the time.

ubiquity gear works well, especially for the price.
There are other vendors with better equipment and higher reliability.
There are licensed bands which afford you LEGAL AND REGULATORY PROTECTION from others who would cause you problems.
Any single link is a "single point of failure". If you really want uber-high-reliability, you will want two+ links, ideally with some path diversity, in different, licensed spectrum.
