With AoA, the direction of the incoming signal is measured by observing the angular phase shifts between the antennas (of the receiving device) as they receive the RF signals. This data can be combined with the signal strength metrics (RSSI) to accurately pinpoint the location of an object or an asset in real-time. The location accuracy based on AoA is usually between 20-30 cm but may vary depending on several factors used in the positioning system.&nbsp; The triangulation-based process in AoA is one of the most used [&hellip;]"}
