AB  - A complete contextual marketing platform including an indoor positioning system 
      (IPS) for smartphones is proposed and evaluated to later be deployed in large 
      infrastructures, such as malls. To this end, we design and implement a novel 
      methodology based on location-as-a-service (LAAS), comprising all the required 
      phases of IPS generation: mall digital map creation, the tools/procedures for 
      offline calibration fingerprint acquisition, the location algorithm, the 
      smartphone app acquiring the fingerprint data, and a validation procedure. To 
      select an appropriate fingerprint location algorithm, a comparison among 
      K-nearest neighbors (KNN), support vector machine (SVM), and Freeloc is 
      accomplished by employing a set of different smartphones in two malls and 
      assessing different occupancy levels. We demonstrate that our solution can be 
      quickly deployed at shop level accuracy in any new location, resulting in a 
      robust and scalable proposal.
