The use of mobile information and service systems can cause an added value in preparation and development of residential and business areas for the involved actors and user groups. Within a practice example (industry wasteland PHOENIX West) potentials are shown how a mobile information and service system can support the area and location development. Starting from the total life cycle of the area possible user groups were identified. T-or each user group within the corresponding life cycle specific functions are developed and subjected to an added value analysis. At last a calculation of profitability was carried out. Thereby costs and revenues were determined to measure the return of investment (ROI) for such a mobile information and service system.
