Suddenly, logistics companies could locate their shipments, fleet managers their vehicles, maintenance operators their staff, and farmers their livestock. Decades after the introduction of GPS and the IoT, industrial adoption of IoT tracking is still gaining momentum.

Global navigation satellite systems rely on signals so weak that, even outdoors under perfect signal conditions, they are drowned out by noise. Near tall buildings, they deteriorate considerably due to shadowing and multipath disturbances. And indoors, they are largely unavailable. This has made indoor positioning with comparable performance to GPS outdoors a gap that companies have been seeking to claim their stake in for years, using a variety of technologies…
