Of course, we'll have to see how good these efforts of relative to normal broadband but they do offer hope that you won't have to choose where to live based on the broadband options.
Which I suppose does help, but only for people who probably already have 4G. So, not very rural.
But you're right. A lot of places that are pretty patchy or non-existent today for cell service, especially 4G, will likely have the same problem even after 5G rolls out.
I just looked at a property this week that's 15 minutes from a major regional hospital and has no access to reasonable wired internet.
I think a lot of people here assume you're either in Manhattan/SF or in some remote section of Wyoming. But, as you say, you don't need to get far away from dense civilization for broadband to be problematic.
I live about 40 miles outside of a major city off a somewhat main road. While I do get Comcast, Verizon FIOS isn't available at my address (in site of the fact that they constantly send me mailings).
