Compact Bluetooth AoA Antenna Board from U-blox for Direction Finding and Indoor Positioning

Compact Bluetooth AoA Antenna Board

The u-blox ANT-B11 delivers high-precision direction finding and 2D indoor positioning. ANT-B11 can be integrated into commercial tracking solutions, ideal for direction-finding applications and indoor positioning in mid-size spaces.

Indoor Direction-Finding, Positioning, and Convenience

ANT-B11 is equipped with u-blox NINA-B411 Bluetooth 5.1 module and runs the u connectLocate software, which executes the unique u-blox angle calculation algorithm. In conjunction with an application board, ANT-B11 functions as an indoor Angle-of-Arrival (AoA) anchor point. The angle calculated by the antenna board does not require any additional processing. Thus, it is ready for use at the application level.

Depending on its orientation, ANT-B11 outputs the final azimuth or elevation angle with high accuracy in fractions of a second. With this information, it is possible to track assets and plot their positions in applications aiming at 2D visualization. For 3D visualization, our customers can keep relying on ANT-B10.

ANT-B11 combines the accuracy of ANT-B10 with the smallest possible package. Thanks to its 29.5 x 93.5 mm compact size, ANT-B11 easily fits existing enclosures or casings. Furthermore, one main challenge in the positioning industry is to provide affordable indoor solutions. With u-blox unique technology, indoor positioning systems with high precision at a reasonable cost are now a reality.
