Localization is one of the main pillars for indoor services. However, it is still very difficult for the mobile sensing community tocompare state-of-the-art indoor positioning systems due to the scarcity of publicly available databases. To make fair and meaningfulcomparisons between indoor positioning systems, they must be evaluated in the same situation, or in the same sets of situations. Inthis paper, two databases are introduced for studying the performance of magnetic field and Wi-Fi fingerprinting based positioningsystems in the same environment (i.e., indoor area). The “magnetic” database contains more than 40,000 discrete captures (270continuous samples), whereas the “Wi-Fi” one contains 1,140 ones. The environment and both databases are fully detailed in thispaper. A set of experiments is also presented where two simple but effective baselines have been developed to test the suitability ofthe databases. Finally, the pros and cons of both types of positioning techniques are discussed in detail.
