There's also advantage to coexistence groups, though as I understand it, that's a SAS value add and not a requirement.
As I understand it, a group of operators could form a co-existence group to ignore each other when determining availability. This would be used when a group of operators agreed to the same timing, uplink\downlink, etc. settings so that they didn't interfere with each other... like how GPS-based operators coexist today. ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP ----- Original Message ----- From: "Steve Jones" <thatoneguyst...@gmail.com> To: "AnimalFarm Microwave Users Group" <af@af.afmug.com> Sent: Friday, February 21, 2020 12:31:28 PM Subject: Re: [AFMUG] [ External ] 450m in 3.5Ghz max STA performance people worry about the contiguous block issue too much. The longest you would go with a non contiguous grant is a day. When the sas get jiggy with each other at night the channels will be redistributed in contiguous blocks. Getting 4 channels for a 40mhz will happen for a period, but man is that a bad business decision for the long term unless there is zero competition On Fri, Feb 21, 2020 at 10:34 AM Ken Hohhof < af...@kwisp.com > wrote: The answer is a bit complicated, for example I suspect the SAS could give you a grant, but not at the full xmt power a 450m is capable of, so your range and modulation is reduced. Probably nobody knows the answer. A few WISPs who participated in ICD might have some idea. But if you are asking can you count on getting 80 MHz out of a total 150 MHz, and also as 2 contiguous blocks, I think we know the answer. Even if it happened initially, that seems unlikely long term. Much advertising hype in our business is based on “could it happen” rather than “can we count on it”. That works with 5G because they are talking about everybody getting gigabit speeds but if everybody only gets 1/10 of that it’s still pretty damn fast. Not sure the same applies if you talk about everybody getting 100 meg but most of the time it’s more like 10 meg. From: AF < af-boun...@af.afmug.com > On Behalf Of castarritt .

If you have cnMeudsa (450m AP) for the sector, you can achieve >750 Mbps (theoretically up to 1 Gbps, but I would be lying to tell you I have ever seen this kind of efficiency in the real world) sector capacity due to the Multi-User MIMO capabilities (i.e. simultaneous transmissions to up to 4 clients in the same time slot). Running under Part 90 or Part 96 does not affect the system performance (provided the channel size is the same, of course).
