A dynamic femto cell architecture using TV Whitespace improving user experience of urban Crowds

For several years, works on cognitive radio have been published allowing to reuse TV Whitespaces. On another hand, many new results appear on user and crowd mobility due to big data recent developments, especially from cellular traces. We propose here a method for cellular resource planning taking into account user mobility. Since users move, the bandwidth resource should also move accordingly. We design a score based method using TV Whitespace, and user experience, to determine from which cell it should be removed and to which one it should be added. Combined with traffic history it calculates scores for each cell. Bandwidth is reallocated on a half day basis. Before that, real traces of cellular networks in urban districts are presented which confirm that static network planning is no longer optimal. A dynamic femtocell architecture is then presented. It is based on mesh interconnected elements and designed to serve the score based bandwidth allocation algorithm. The score method along with the architecture are simulated and results are presented. They confirm the expected improvement in bandwidth and delay per user while maintaining a low operation cost at the operator side.
