CoreHW Locator

The CHW1010-LOCN2-1.0 locator is an evaluation kit locator device intended for developing indoor positioning systems based on Bluetooth^® AoA technology. This locator incorporates CoreHW ANT1 AoA antenna array board and CoreHW IPS Main Board. The ANT1 antenna array board features 8 dual linear polarized patch antennas and the CoreHW CHW1010 SP16T antenna switch, which can be employed to control and sample RF signals for Bluetooth^® AoA and AoD technology.

CoreHW IPS Main Board is equipped with Nordic Semiconductor nRF52833 SoC, which controls CoreHW 1010 antenna switch and performs I/Q-sampling of packets sent by tags. The main board also contains ST Microelectronics STM32 MCU, which executes CoreHW proprietary angle estimation algorithm to calculate 2D (Azimuth & Elevation) estimates for tags. The calculated angle data can then be conveyed for further processing on positioning system through interfaces such as Ethernet, USB (virtual serial port), HW UART, or SPI.

CoreHW offers an AoA demo system complete with CoreHW firmware and Windows PC positioning engine software, including a user interface (GUI). This system encompasses four Gen 2 locators and is suitable for both laboratory tests and preliminary evaluations in real-world use case scenarios.
