The Bottom Line: The Battle For 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.

Constellation Research recommends that readers consult a stock professional for their investment guidance. Investors should understand the potential conflicts of interest analysts might face. Constellation does not underwrite or own the securities of the companies the analysts cover. Analysts themselves sometimes own stocks in the companies they cover—either directly or indirectly, such as through employee stock-purchase pools in which they and their colleagues participate. As a general matter, investors should not rely solely on an analyst’s recommendation when deciding whether to buy, hold, or sell a stock. Instead, they should also do their own research—such as reading the prospectus for new companies or for public companies, the quarterly and annual reports filed with the SEC—to confirm whether a particular investment is appropriate for them in light of their individual financial circumstances.
