The
nRF52811 SoC is the 4th addition to the nRF52 Series, and adds capabilities for
Bluetooth® Low Energy (LE) Direction Finding. Direction Finding enables
positioning solutions to not only rely on received signal strength indicator
(RSSI), but also the actual direction of a signal. This improves accuracy
significantly and opens new possibilities for applications in this segment.
There are two types of methods for determining direction, angle of arrival (AoA),
where the direction of the received signal is calculated, and angle of
departure (AoD), where the direction of the transmitted signal is calculated.
The nRF52811 SoC is the perfect choice as a transmitter in both the AoA or AoD
scenarios, with its low power character and connectivity features.
