Dr. David Lopez-Perez from Bell Laboratories presented a seminar at FIU on the topic “Towards 1 Gbps/UE in Cellular Systems: Understanding Ultra-Dense Small Cell Deployments,” on Thursday, March 5, 2015.
Abstract
Today’s heterogeneous networks comprised of mostly macrocells and indoor small cells will not be able to meet the upcoming traffic demands. Indeed, it is forecasted that at least a 100x network capacity increase will be required to meet the traffic demands in 2020. As a result, vendors and operators are now looking at using every tool at hand to improve network capacity. In this epic campaign, three paradigms are noteworthy, i.e., network densification, use of higher frequency bands and spectral efficiency enhancement techniques. This talk discusses current heterogeneous networks and aims at bringing further common understanding, analyzing the potential gains and limitations of the three mentioned paradigms to enhance network capacity, together with the impact of idle mode capabilities at the small cells as well as the user equipment density and distribution. Special attention is paid to network densification and its implications when transitioning to ultra-dense small cell deployments. Other aspect such as the impact of network densification in cell schedulers and energy efficiency will be discussed too.
