u-blox<\/a><\/strong> has announced the u-blox ANT-B10 antenna board for Bluetooth direction finding and indoor positioning applications. Designed for integration into commercial end-products, the board enables low power, high-precision indoor positioning and speeds up evaluation, testing, and commercialisation of Bluetooth direction finding and indoor positioning solutions.<\/p>\n\n\n\n

Bluetooth indoor positioning uses the angle of arrival (AoA) of a Bluetooth direction finding signal emitted by a mobile tag at several fixed anchor points to calculate the tag\u2019s location in real-time with sub-metre accuracy. The technology, which benefits from Bluetooth\u2019s vast ecosystem and interoperability across platforms, is gaining traction due to its low cost, high accuracy, and relative ease of installation and maintenance.<\/p>\n\n\n\n

Assembling an AoA indoor positioning anchor in seconds<\/strong><\/p>\n\n\n\n

ANT-B10 is a self-contained Bluetooth low-energy antenna board for direction finding and indoor positioning. The board, which features an antenna array comprising eight individual patch antennas, is built around a u-blox NINA-B411 Bluetooth 5.1 module. After processing incoming RF signals emitted by mobile tracker tags in the module\u2019s radio and angle calculation processor, the solution outputs the calculated angle of arrival without requiring any additional processes.<\/p>\n\n\n\n

The release also includes the XPLR-AOA-3 explorer kit. It features an application board, which offers developers a quick and easy way to evaluate and test the ANT-B10 antenna board, as well as u-blox\u2019s direction finding algorithm. An off-the-shelf pin header on the application board allows for easy bring-up and testing of ANT-B10 and third-party antenna boards. And connecting the two boards yields a ready-to-use AoA indoor positioning anchor point in seconds.<\/p>\n\n\n\n

End-product integration<\/strong><\/p>\n\n\n\n

ANT-B10 and XPLR-AOA-3 complements the existing u-blox indoor positioning offering, which includes the popular XPLR-AOA-1 and XPLR-AOA-2 kits. Using u-connectLocate, which runs on ANT-B10\u2019s Bluetooth module, solution developers can easily execute the angle calculation algorithms using AT commands. When combined, the solution suite is ready to go for end-product integration.<\/p>\n\n\n\n

Common use cases for Bluetooth indoor positioning and direction include tracking assets in industrial settings such as in warehouses as well as people and things in hospitals, retail environments, or museums. Additionally, access control systems deployed in connected buildings can use angle detection to determine which side of a door users are located on.<\/p>\n\n\n\n

Actively engaged with the technological ecosystem<\/strong><\/p>\n\n\n\n

To determine the angle of arrival of incoming signals for direction finding, the ANT-B10 board concurrently processes them on all eight patch antennas. Because implementing multiple RF paths connected to multiple RF switches unnecessarily increases power demand and introduces errors, the ANT-B10 board uses an industry-leading single RF switch component from u-blox partner CoreHW that cycles through the eight antennas at a microsecond timescale.<\/p>\n","protected":false},"excerpt":{"rendered":"
