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.

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.

I can't think of any others in 120 degree off hand.
