Wi-Fi RTT (Round-trip time) is a brand new technology that allows locating devices with unprecedented sub-meter accuracy. It measures the distance between a device and a router, which is way more accurate than using a GPS signal. The technology is applicable for tracking vehicles and cargo within warehouses and production plants. It is effective for public hotspots as well, such as offices and malls, airports, exhibitions and not only. The first implementations are coming soon in Q1 2020, with orders confirmed from a big carrier and one logistics company.
