Revision History Date Version Description 2020/01 1.0.0 First Release 2021/08 1.1.0 Change dimension data to high resolution 2021/11 1.2.0 Change dimension data (Chip Antenna) RN52e Datasheet 4 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. 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. RN52e Datasheet 5 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. Enhancing beacon applications The RN52e SoC gives the opportunity to enhance beacon applications to leverage the Long Range feature introduced in Bluetooth 5, in addition to Direction Finding introduced in Bluetooth 5.1. It achieves longer range without adding more costly components, providing an ideal option for cost-sensitive beacon applications. The ultimate network processor The RN52e offers comprehensive connectivity with a long list of capabilities and features. It is capable of all the latest features of Bluetooth, including Long Range and Direction Finding, but also 802.15.4, Thread and Zigbee. This comprehensive connectivity offer makes it the ultimate network processor, and paired with a companion MCU, it offers great value in for example gateway and router applications for smart home. Get started today The RN52e is supported by the nRF5 SDK, providing all the necessary examples, libraries and drivers to get started with development. SoftDevice S112, a Bluetooth 5 protocol stack, is already qualified for it, providing high throughput with 2 Mbps and improved coexistence with channel selection algorithm #2. In addition, a Thread connectivity solution is available in the nRF5 SDK for Thread and Zigbee. RN52e Datasheet 6 2.1.
