The advantage the FWA folks have is that it is significantly more financially viable to not oversubscribe (or oversubscribe less) when you deliver more users from a more centralized next hop location. In other words, it’s easier and cheaper to have 100 Gbps serving 1000 users from a single location than it is to have 1 Gbps serving 10 users from 100 different locations. Which is not to say that there aren’t other challenges in FWA environments relative to FTTx environments, but system capacity (you can always add more radios, with enough available spectrum, at least) isn’t one of them.<br><br><div dir="ltr">Dave Cohen<div>craetdave@gmail.com</div></div><div dir="ltr"><br><blockquote type="cite">On Oct 5, 2023, at 6:17 PM, Dick Roy via Nnagain <nnagain@lists.bufferbloat.net> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">

bits/sec/Hz/km^3)???? I am suspicious that the capacity falls way short of
that which cable guys have at their disposal, and that as the FWA networks get
loaded, performance is going to degrade dramatically ultimately resulting in
churn back to the cable guys. It's very expensive to compete with already sunk
FTTH or even FTTC. <o:p></o:p></span></font></p>

are losing subscribers (at material levels) to one of the three new national 5G

the effects of $45B+ of grant money dedicated to underwrite new broadband
access network construction - that is also pretty material. <o:p></o:p></span></font></p>
