Microsoft Indoor Localization Competition: Experiences and Lessons Learned

We present the results, experiences and lessons learned from the 2014 Microsoft Indoor Localization Competition. 22 different technical approaches to indoor location competed in the same unfamiliar space over the course of 2 days, allowing us to directly compare the accuracy and overhead of different technologies. In this article, we provide a high-level analysis of the competition’s results, discuss the current state-of-the-art in indoor localization, and highlight the areas that, based on our experience from organizing this event, need to be improved to enable the adoption of indoor location services.
