Broadcom has just rolled out a chip for smart phones 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. The variety of location data available to mobile-device makers means that in our increasingly radio-frequency-dense world, location services will continue to become more refined.
Wow, the implication of this for #theinternetofthings is huge.
