SP16T RF Switches Optimized for Real-time Location System (RTLS)

CoreHW CHW10X0: AoA and AoD Switch

CHW10X0 enables very high direction-finding accuracy needed especially for products with Bluetooth® 5.1 Angle of Arrival (AoA) and Angle of Departure (AoD) indoor positioning feature. CHW1010 and CHW1020 are the new generation RF Switches designed to transfer real-time location data with powerful indoor positioning and exceptional power efficiency. 

 The CHW10X0 series offer unmatched direction-finding precision, especially crucial for Angle of Arrival (AoA) and Angle of Departure (AoD) indoor positioning capabilities. These switches revolutionize indoor accuracy and bring the pinpoint accuracy of GPS to indoors, achieving three-dimensional direction finding using multiple beacons. 

 Notable benefits of CHW10X0 include its compact footprint and smart design, eliminating the need for several previously required components.
