Paper Title
Low-Cost Location System for Airports

This paper describes a solution to the problem of location in airports, which are places where the use of GPS devices is impossible or not sufficiently precise. The new proposal is based on a combination of methods that allow obtaining useful information about the location in this type of places. In particular, an Android application has been implemented to show the applicability of the proposed solution, which adds a layer of security because it is very important to protect positioning information to avoid the possibility of traceability of system users.
