The nRF52811-QFAA-B-R7 SoC is the fourth new member of the nRF52 family and adds Bluetooth® Low Energy (LE) direction finding functionality. Direction finding enables location solutions not only to rely on the received signal strength indicator (RSSI), but also on the actual direction of the signal. This significantly improves accuracy and opens up new possibilities for applications in this segment. There are two ways to determine direction, Angle of Arrival (AoA), where the direction of the received signal is calculated, and Angle of Departure (AoD), where the transmitted signal is calculated. The nRF52811 SoC is used as a transmitter in AoA or AoD scenarios with low power consumption and connectivity.
