  • Author: Peter Karlsson

The success of satellite-based positioning in outdoor environments has created pent-up demand for equally ubiquitous, accurate, and reliable indoor positioning solutions. Bluetooth®has come forward with a strong candidate to fill this gap with direction finding, a recent addition to the Bluetooth specification that makes it possible to determine the direction that radio signals travel from a mobile tag to one or several fixed anchor points. When a constellation of such multi-antenna anchors is deployed, an angle-of-arrival (AoA) methodology can be used to triangulate the precise location of a mobile device or tag.

In this white paper, u-blox provides an introduction to Bluetooth high precision indoor positioning,explore what is needed to deploy such a solution, and share lessons learned trialing the technology in an industrial warehouse.
