LOCN2-1.0 Locator

CHW1010-LOCN2-1.0 Locator is a Bluetooth AoA development kit locator device intended for indoor location system providers. The locator includes CoreHW ANT1 AoA antenna array board and CoreHW IPS Main Board. The ANT1 antenna array board contains 8 dual linear polarized patch antennas and CoreHW CHW1010 SP16T Bluetooth AoA/AoD capable antenna switch for Bluetooth AoA CTE sampling.

CoreHW IPS Main Board, contains Nordic Semiconductor nRF52833 BLE SoC, which controls CoreHW 1010 AoA antenna switch and performs I/Q-sampling of CTE advertising packets sent by compatible Bluetooth AoA Tags. The main board also contains ST Microelectronics STM32 MCU, which runs CoreHW proprietary angle estimation algorithm to calculate 2D Angle-of-Arrival (Azimuth & Elevation) estimates for AoA Tags. Calculated angle data can then be passed for further processing on positioning system via Ethernet, USB(virtual serial port), HW UART, or SPI interfaces. CoreHW offers an AoA demo system with CoreHW firmware and Windows PC positioning engine SW with user interface (GUI). The demo system contains four Gen 2 locators. The demo system can be used for laboratory tests and for initial testing in real use case scenarios.
