5G Coverage for IOT

Was recently asked to give an opinion of 5G use in the Cincinnati area for potential IOT applications,  with mobility implications,  and was pointed to this map.  Which can be used US country wide.  This particular map gives you only AT&T 3G to 5G.   It implies it is frequently updated.  You can click on the map for many locations in the US, zoom in, etc.   Useful for early analyses of applications.  etc.   Please pass along pointers to any other resources of this type.

Always thought there was a place for simple buttons to link to IOT networks, to make requests of many kinds, beyond just ordering something.   Why doesn't IFTTT have something like this?  This seems to be that,    The way I read it,  although provided through AWS,  it is not an Amazon Echo infrastructure thing.  Will be interesting if that  changes.

AT&T's button was also designed more for businesses than homes and individuals. It's not pre-programmed like Amazon's Dash buttons are, and companies can program it to accomplish tasks that fit their needs. .... "
