256x256 MIMO to many customers at once is kind of a big deal. Fiber is just starting to get into more than one spatial stream.

Physics may limit any new tech, but really we havent seen any wireless advances, just wider bandwidth, higher modulation, more subcarriers. To me, a true advancement is an improvement without major cost. Everyone of those improvements tends to come at an SNR cost at minimum and SNR is something we are already losing. Sure theres improved SNR with moar power, but thats just diminishing the aggregate to improve the minute On Wed, Mar 8, 2023 at 10:52 AM Chuck McCown via AF < [email protected] > wrote: I am impressed at the advancements with wireless over the years. I would have never expected to be able to deliver PMP 100 Mbps with any quality at all. And we all know that 100 mbps will do almost everything anyone would ever need, still we have fiber customers wanting 1. 2.5 and 10 gig... And to think that we used to be so happy to advertise 10 Mbps on Canopy. That burst mode was the bomb until Netflix arrived. -----Original Message----- From: [email protected] Sent: Wednesday, March 8, 2023 7:37 AM To: 'AnimalFarm Microwave Users Group' Subject: Re: [AFMUG] Shadenfreude Almost sounds like you're not serious. Fiber really is the future. How much wireless bandwidth is there to work with? If we kicked out all incumbent microwave users and made it all available for WISPs there'd be what, 50 GHz? More realistically 5-10GHz that you could really use for the last mile....assuming they'd allocate all of it for a WISP. Within the reality of the regulatory framework we've got more like 1-2GHz available. Bandwidth of a single mode fiber is ~50 Thz. Even the most optimistic estimate for wireless doesn't compare. 100Gbps ethernet on fiber uses only a tiny fraction of the possible bandwidth and very primitive modulation. It's not because you couldn't do 1024QAM with a laser, it's just that right now we don't need to. Theoretically pushing Shannon-Hartley to the limits you could run 1.2 petabits per second on a single mode fiber. That's a million gigabits. Clearly there are badly implemented networks, but that just means a dumb person did it. If you're not branching out into fiber you'll eventually be left behind. IMO, the only debatable part is how many years that'll take. -Adam -----Original Message----- From: AF < [email protected] > On Behalf Of Matt Hoppes Sent: Wednesday, March 08, 2023 8:57 AM To: AnimalFarm Microwave Users Group < [email protected] >; Jan-GAMs < [email protected] > Subject: Re: [AFMUG] Shadenfreude But...
