Femtocells in 3G Mobile Networks

This paper investigates influence of femtocells to the traditional mobile network hierarchy and their features. This upcoming technology is supposed to be widely deployed in the upcoming wireless and mobile networks. These small base stations are designed to improve indoors capacity, reducing macro cell traffic or to provide services in locations without signal or with weak coverage. The paper discusses usage of femtocell and related challenges, such as interferences, frequency spectrum planning, handovers or integration of femtocells into mobile networks.
