Akey technology in the autonomous home is Ultra-Wideband (UWB), a wireless technology that can detect location to within 10 cm (4 inches) and supports radar features that gauge small changes in direction.
UWB makes it possible to know where people are, with a high degree of precision, and movement. UWB is what lets lights and blinds respond to your presence, and makes entryways lock or unlock, depending on whether you’re moving away or toward the door.
