More specifically, the Federal Communications Commission (FCC) and the Federal Aviation Administration (FAA) prohibit the use of cellular phones and other wireless devices on airborne aircraft because of potential interference with wireless networks on the ground, and with the aircraft's navigation and communication systems. Within this context, we propose in this paper a movement recognition algorithm that will switch off a module including a GSM (Global System for Mobile Communications) device or any other mobile cellular technology as soon as it senses movement and thereby will prevent any forbidden transmissions that could occur in a moving airplane. The algorithm is based solely on measurements of a low-cost accelerometer and is easy to implement with a high degree of reliability. 1. Introduction GSM localization or mobile phone tracking is a technology used to locate the position of a mobile phone. Localization uses the concept of multilateration of radio signals, where the phone must communicate wirelessly with at least three of the nearby radio base stations (RBSs). Knowing the position of the RBS¡¯s, and using a triangulation method, an approximation of the geographical location of the mobile phone can be calculated. This technology is based generally on four different techniques: network based, handset based, hybrid and subscriber identity module (SIM) based [1]. The SIM-based technique is of interest in this paper, where by using the SIM in mobile communication handsets it is possible to obtain raw radio measurements that include the serving cell ID, round trip time and signal strength. Different applications already use this service for localization, for example, resource tracking with dynamic distribution such as taxis, rental equipment, or fleet scheduling. Within this context, Swisscom AutoID Services (SIS) in collaboration with La Poste Suisse aims to pioneer a service that will allow clients to be able to track and trace their packages in near real-time mode anywhere in the world. The service will consist of including a tracker with the package that operates on the GSM network for location and communication [2]. Therefore, a key issue arises when the package is transported via airplane. Indeed, it is well known that aircraft remains one of the few places where the use of mobile communication signals is prohibited [3, 4]. In fact, the aircraft is not a good Faraday cage and cannot prevent transmissions to reach %U http://www.hindawi.com/journals/ijvt/2013/149813/
