Can you please explain further?  And how far are you using the towers to cover?

It gets rather difficult to do that in a busy network covering lots of area.

But don’t you use down-tilt to minimize the coverage so towers can’t hit each 
other?

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 ☺ and 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

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.
