RN52e Datasheet 2. Overview The RN52e module based on the nRF52811 SoC is the 4th addition to the nRF52 Series, and adds capabilities for Bluetooth® 5.1 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.
RN52e Datasheet Real time locating system Above you see an example of a real time location system (RTLS) where the principle of AoA is used to determine the location of an tag. The tag is just a simple beacon, broadcasting. Each locator determines which direction the signal is coming from and together with the location engine they are able to calculate the location of the tag.

RN52e Datasheet 6. Module Reference The RN52e module can operate only by connecting VDD and GND.
FCC STATEMENT This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
2.5 Trace antenna designs Not applicable. The module has its own antenna, and doesn’t need a host’s printed board microstrip trace antenna etc. 2.6 RF exposure considerations The module must be installed in the host equipment such that at least 5mm is maintained between the antenna and users’ body; and if RF exposure statement or module layout is changed, then the host product manufacturer required to take responsibility of the module through a change in FCC ID or new application.
2.8 Label and compliance information Host product manufacturers need to provide a physical or e-label stating “Contains FCC ID 2A7LK-RN52E With their finished product. 2.
