Examples? I don't know of any phased array PtP/PtMP system, at all, in anything like the form factor and pricing of Starlink or something like Ubiquiti's airMAX/airFiber/LTU series operating in the 5, 11, or 24GHz class spectrums. In fact your whole comment makes zero freaking sense, what do you mean "phased array wisp thing"? I don't see how it'd fundamentally be any different then all the very successful WISPs I'm familiar with, or for that matter the LR-LAN stuff that I've done myself. The advantage would be in that one of the trickier bits at longer ranges is getting alignment just right, labor or kit correcting for shifts, and tradeoffs in allocating regulatory max transmission power budget across end points. Skilled personnel can of course learn the alignment part reasonably and an important differentiator for a long time amongst different kit was the kind of tools it had to help with alignment. But it's not nothing and it can take a while, and then there is the rest.

A phased array system like Starlink's that could make its way into $150-500 CPE and hopefully <$5k basestation would be a nice evolution. Only need to get it roughly aimed in the right direction and then the system does the rest with no further human intervention, zero skill required. Basestation could extremely rapidly reallocate high power to various end points which matches consumer load patterns well rather then having to pick 30°/60/90/120/3x30/whatever sector antennas or 4'+ dedicated big boys for real distance.

I have no idea where this "4/5g physics" thing came into your head from. We're not talking physics we're talking economics and barrier to entry.
