Inference-Driven Dynamic Access Scheme for Interference Management in Heterogeneous Networks
Recent statistics have shown that more than 50% of voice calls and more than 70% of data traffic originate from indoor cellular subscribers. Yet, historically, substantial activities in wireless research and development have focused on high speed mobile users and the resulting fast fading channel problems. In fact, current cellular technologies and deployment tend to exhibit poor indoor coverage, especially for high speed data services whose broadband requirement suffers severe channel distortions and packet losses in complex indoor environment. One recent proposal for improving indoor wireless coverage introduces the promising concept of Heterogeneous Networking (HetNet) and more specifically the deployment of femtocells.
