A New Microchip Knows Just Where You Are, Indoors and Out
Broadcom has just rolled out a chip for smartphones that promises to indicate location ultra-precisely, possibly within a few centimeters, vertically and horizontally, indoors and out.
The unprecedented accuracy of the Broadcom 4752 chip results from the sheer breadth of sensors from which it can process information. It can receive signals from global navigation satellites, cell phone towers, and Wi-Fi hot spots, and also input from gyroscopes, accelerometers, step counters, and altimeters.
