Ultra-Wideband, also known as UWB, is a radio technology that uses precisely timed, short pulses of energy at a low power level. These short UWB pulses have a cleanly deﬁned start time, which allows the UWB Readers to measure the exact time when a given tag is heard. This measurement is called the Time of Arrival, or “TOA”. When the same tag signal is heard by diﬀerent Readers placed around the area, the slight diﬀerences in signal timing can be compared, determining the location of the tag. This means you get centimeter-level tracking accuracy in real-time.
Bluetooth® Low Energy (BLE)
Bluetooth® Low Energy (also known as BLE) is a standard for connecting various wireless devices with other BLE enabled network devices. Our sister company, BlueCats, specializing in BLE hardware and comprehensive smart location management platforms, provides BLE beacons that emit a BLE signal picked up by BlueCats’ gateways, the Edge Relay. The same PLUS software used to process UWB signals analyzes the BLE signal strength and other characteristics to determine the approximate location of the beacons relative to the Edge Relays. With BLE, you can achieve meter-level tracking accuracy, which makes it a good option for tracking approximate locations of slow-moving assets.
