I've been an advocate for four sector layouts for a long time. Two
channels with frequency re-use back to back. Three sectors means three
channels which means less spectral efficiency.
I suppose carriers have more channels than I do :)

The carriers are mostly only deploying 65 degree sectors at the macro
level. Telrad I believe only recommends 65 degree sectors now.
Typical 360 degree coverage is three 65 degree sectors or possibly
four if needed for capacity, not coverage.
Whole different world for sure.
Thank you,

I suppose if you're planning a macro TD-LTE network, all of your cells
are the same size and evenly spread out. That never works out IRL for
a WISP. Beam steering is where we need to go, but a WISP can't afford
eleventy brazillion dollars per site.
The Cambium/Laird "90" degree sectors have null-full and seem to work
very well for nearly every scenario with the 3.6 450. 60 to 240 feet
high on sites with SMs as close as 1/4 of a mile. We do have some
customers a hundred or two feet away (like an elevator office) and
they do end up seeing the back side of the opposite sector a bit, but
so far it hasn't been much of an issue. Just today we put a customer
about 15 degrees from the "edge" of a "90" and there was still plenty
signal there. The pattern does get kinda skewed and lumpy out that far
though, and you can see that in the beamwidth plot. Good enough until
we add another sector and turn things a bit.

But 4 degrees downtilt on a sector with 7 degree vertical
beamwidth seems excessive unless you’re doing really small cells.

Alpha Wireless makes a great sector. Alpha is the antenna OEM for
Telrad and Airspan among others.

If you need more information let me know offlist.

KP makes one - I haven't used them myself, but I've always only
ever heard good things about their antennas. I can't think of any
others in 120 degree off hand.
