Femtocells for next-G wireless systems: The FREEDOM approach

The paper deals with femtocell in context of next generation wireless systems. Actually, in the framework of the ITU, the definition of IMT.ADVANCED systems is on-going and all the candidates already investigate the usage of femtocells to improve system capacity. On the other hand, femtocell market is still at its early stage, facing the competition of low-cost, easy to use WiFi equipments. This paper presents the concept of femtocell and the related challenges and promising technical solutions to make them happen in the framework of next generation of broadband OFDM system.
