AoA Demo Kit System


AoA Demo Kit System: CHW1010-EVKN2-1.0

CoreHW Gen2 Angle-of-arrival (AoA) Demo System (CHW1010-EVKN2-1.0) for the CoreHW SP16T AoA/AoD Antenna Switch provides a hardware environment for demonstration and testing of BT5.1 AoA indoor positioning accuracy. The demo system is not developed for production usage and PC software does not support all features needed for mitigation of such as interference and multi-path reflections.

The system can be used for laboratory tests and for initial testing in the real use case scenarios. It provides support to locator product development and development of final end-to-end RTLS solution.

The AoA demo system contains four CoreHW Gen2locators and two tags. CoreHW firmware is used in the tags and locators to enable AoA measurement. The demo system uses ethernet interfaces to connect locators to Windows PC which has position engine software with user interface (GUI).
