Down tilt doesn't buy squat when you have terrain. We have some towers
that have to tilt up, and others that have to tilt down. We have
adjacent towers that are 1,000, even 2,500 feet elevation different.

It all depends on the particular network and the terrain you're
dealing with. If you're mostly doing micro-POPs where your "tower" is
a tripod on a house roof (we have several of those), then yes, it
isn't such a big deal to be able to sync with other towers, since most
of them aren't going to be able to see eachother anyway, but if you're
primarily on grain legs and actual towers that are 100'-300' and they
might have LOS to a dozen other towers, then it's a very big deal to
be able to sync the towers with eachother - if you don't have sync it
gets to be a nightmare to try and coordinate everything.

Multiple towers don’t really matter much with 256QAM OFDM with
Ubiquiti because you have to plan on short ranges to get maximum
modulation rates. With tighter beam patterns on sectors and even
customer radios with 30dBm F/B ratios, the reality is users won’t have
multiple towers causing interference anyway. There is more
interference from indoor wireless routers than other towers. I think
it really only matters on 1 tower.
In reality though, you are still better to just plan your Ubiquiti
deployment on the tower without GPS and even then, try to stagger the
antennas on the tower and keep them as far apart as possible to
minimize interference. That’s how we did our last tower. Oh, and use
RF Armor. That may change someday but it’s the reality today.

With the channel size required, or the number of small sectors
required to meet bandwidth demands in pmp in the day of ac not having
a functional multisite timing solution, whether GPS or goat heartbeat
based, it's better to start selling shoes instead of radio's. Just
syncing a single site has limited value, all the sites have to play
together. Ubnt is like the drunk uncle who promises the world. I like
announcements, ubnt has some really good looking marketing, swift
peppy videos, and logos and sweet fonts, but it would be nice of uncle
drunkey would sober up for a couple days and deliver some product. I'm
singling them out because they tend to have the most announced but not
out products at any given time.

They were talking about the new Prism radio, which doesn't have those
deficiencies (at least once certified).

Yea, I wanted to be there. Got offered several free dinners Jand I
never turn down food.. But got to play 5 baseball games and 3 of them
in the Angels spring training stadium.

Except that it doesn’t support UNI-I or even some DFS frequencies. Or
is that a limitation of the firmware and not the hardware?

>> what is the difference with the current RocketAC that already has the
Prism system in it?
The RocketAC-Prism has three important new things going on from what I
can tell:
-TX filtering.. lower OOBE emissions mean higher power on channels
closer to the band edge
-Expanded RX filtering range.. Old prism was 5480-5850, new prsim is
5150-5850
-GPS Sync is back.. unknown benefits, time will tell.
