The MobilAlarm project tested an innovative, location-independent alarm and teleassistance service which enables older people, chronically ill, and other persons at risk to initiate an alarm call whenever and wherever he or she needs or wants to do so. The project analysed the European market for such services in general, and in particular developed and tested business models in three distinct markets. This involved providing such services to selected user groups over an extended period of time. Finally, a comprehensive plan for fast market roll-out and diffusion across Europe was developed, and market deployment was initiated. To establish such an efficient, trans-European service meeting the needs of users across the European Union, various British, German and Spanish partners – representing the whole value chain – were involved in this project.
