911 Product guy here...
TL;DR, this is nothing new.
Carriers have offered location of your device for 911 calls for years now, through a set of metadata called Automatic Location Identification (ALI).
This is only provided to 911 (police & fire) by carriers alongside your 911 call.
Mobile Device Manufacturers can also provide "precise location" to 911 for the same calls, but that's a separate form of data and closely secured.
Bottom line - Carrier data has always been less precise, but more readily available. Device data (i.e. Apple and Google) is more precise, but harder to access.
But it seems this article is arguing is that there is another (non SMS based) way of accessing the precise location data which is not so difficult to access.
