We use the Dual Pol Yagis on APs to get a narrower beam. Not 10 degrees but better than a 60 or 90 sector and smaller. Also better gain to suck in a signal.

It looks like the TVWS is a non-starter, but we should take another look at 900 MHz. We are fortunate in that the areas are typically grouped very narrowly in one direction. We figured we could cover the area with a 10 degree sector if we could find one that narrow. We’ll see what we can find for 900 MHz equipment out there.

I have no idea why Microsoft thinks that TVWS has merit or what technology they bring to the party, but I guess you could investigate it. I have to agree with the others, it was never very attractive, and gets less so as time passes and people want to do video streaming and Zoom meetings and download 100 GB games over the Internet, and as other technologies advance. I would also ask, what if Starlink actually works, and is months away from general availability. It may not be a threat to WISPs in general (or maybe it is), but it would seem to solve this particular problem. And what if Starlink succeeds in getting RDOF or CAF subsidy money? Wouldn’t you just be lighting hundred dollar bills on fire? As far as 900 MHz, we stopped using it. The reason wasn’t so much RTK (a lot of which is moving to 450 MHz anyway), but smartgrid and smartmeters. If the power company or other utilities put in 900 MHz smartmeters, kiss 900 MHz goodbye for broadband. The other problem was that it was always more art than science, sometimes it wouldn’t work and the reasons wouldn’t be clear. It’s touch to plan or troubleshoot when, by definition, you don’t have clear line of sight. There’s also the issue of other WISPs in 900 MHz, but it sounds like you wouldn’t have this issue. But the Cambium 450 900 MHz stuff does work, and even though you only have 28 MHz total to work with, you can use a wide enough channel to get decent speeds. We still have one AP in service with a handful of customers on it. I would steer clear of 900 MHz omni antennas though. If you can’t justify sectors, just don’t do it.

From: David Coudron Sent: Wednesday, September 9, 2020 7:52 AM To: AnimalFarm Microwave Users Group Subject: [AFMUG] TV White Space We have a couple of areas in our network that remain problem coverage areas. The typical scenario is a handful of customers that are 5-10 miles from a decent tower structure, but really want service. We have usually either passed on providing coverage, or messed around with relaying from other customers or some other messy scenario. We are looking for a workable non-los solution for these few spots. We don’t need to get dozens of folks on a tower, and a higher than normal cost is OK, but it needs to be stable enough it is better than the relays and other messy solutions we have come up with. We keep looking at 900 MHz, but it looks like Cambium is the only one left in this game, and we are pretty worried about noise as we are in the middle of farm country and the RTK stuff is pretty prevalent. Has anyone had enough experience with TV white space to develop an opinion on its ability to be used in this situation? There only seems to be two vendors in this space, Redline and Carlson, but maybe there are others we are missing. We are looking for a solution that would cover customers 5-7 miles in non-los situations with rate plans of 20-25 Mbps. Is this possible?
