Who needs it...
Just proliferate the air with great wifi data streams where spectrum is
abundant as water.

Our region is pretty noisy and getting noisier. Currently we are using
Ubnt Rocket 90deg sectors although I have considered these to really be more
like 75 degrees due UBNT using -6dB as the rolloff point.
We have seen a dramatic improvement with a Titanium sector and plan on
replacing the other rockets with Titaniums and considering going to 60deg or
maybe even 45 degree and using GPS sync to reuse channels.
What if any have been your experiences with going to narrower sectors for
a given area? I would expect to see ~3dB improvement in links just by reducing
the antenna pattern, and ~3dB due to power density. Additional gains might be
made from improved F/B rejection and improved shielding, possibly another ~3dB?
This could mean anywhere from 6-9dB improveme nt on every link.
What are your experiences with UBNT GPS? We would not use dynamic, but
rather fixed downlink %. I know we will give up some B/W but better spectrum
management might be worth the trade. The link improvements should push the
radios into higher modulation further mitigating the loss by using GPS
Thoughts?
Comments?
