The Bottom Line: The Battle Of Last Inch Connectivity Is Here

From Starlink to Comcast and Verizon, delivering on the last mile has been a goal.  Reaching the last inch has come with Apple AirTags with Bluetooth tracker and Amazon Sidewalk with Tile.  As tech giants double down on neighborhood and micro mesh connectivity, expect more partnerships and innovations.  Amazon has smartly enabled many of its Echo devices and all of its Ring devices to extend these networks providing mesh coverage and keeping its devices sticky and deliver more value added digital services.  This latest battle for the last inch will result in only a handful of players, creating the next opportunity for connected services.
