Assessment of Dynamic Spectrum Allocation in Realistic Mobile Networks

Since the advent of radio communications, radio spectrum has been increasingly getting crowded with different kinds of applications. Different radio communications systems have been developed for various purposes and multiple actors became interested in using these systems at the same time and space. Such situation inevitably led to the point...

Virtual Sectorization in Future Mobile Networks: System-Level Assessment and Optimization in a Realistic LTE Network

Virtual Sectorization (ViS) is proposed as a solution to cope with the exponential growth of data traffic in mobile networks. Through the use of an Active Antenna System (AAS), two vertically separated beams (serving two distinct cells) are created within the original coverage area of a macro-cell. One of these cells, referred to as virtual cell...
