NXP 2021 11 KW39/38/37 WIRELESS MICROCONTROLLERS LEARN MORE u mean the difference between life and death. Streamlining the management of life-saving resources can save lives and make hospitals more efficient. Second is the establishment of situational awareness associated with precision ranging. With precise ranging in real-time, systems can be built to determine the context around moving assets. For example: Are the assets getting closer or further apart? Without precision, such a system would usually prove unfeasible. Imagine just how efficient an industrial operations environment can be when you have precise tracking of assets. Third is the aspect of learning. The precise data that precise ranging can bring means neural net algorithms will have better quantitative data to apply to the challenges they are being asked to solve. As a result, we can make significant advancements in efficiency in route optimizations, maintenance, and the flow of assets based on machine learning loaded with precise locationing data. The System Solution and NXPs Contribution Many applications can benefit from a comprehensive UWB system solution. The automotive industry represents one of UWB's deployments. When connecting several UWB anchors, data from different devices can supplement ranging with angular information to determine more than just distances. The complex system integrates vehicle body controller integrated circuits, certified secure elements, and Bluetooth microcontrollers to enhance the UWB ranging and assist with vehicle networking and managing power consumption. KW37 Bluetooth Microcontroller A vital piece of this complete precise ranging solution is the Bluetooth microcontroller. NXP's recently launched KW37 family of devices provides this critical function for today's UWB systems. With full Bluetooth 5.0 compliance, the extended- range capability of the KW37 allows for communications with smartphones or key fobs that can then prime the UWB sensors before enabling the more precise ranging. The Bluetooth connectivity can bridge the broadly adapted RF communications deployed into the UWB domain that operates in different RF bands. This fusion between the ultra-low-power and low complexity Bluetooth microcontroller and the highly precise UWB transceivers will optimize precise positioning in the IoT and automotive industry. ■ One of the great promises associated with the IoT is the efficiency that the technology can bring. ❝ ❞
