Technologies for future broadband wireless evolution

The paper discusses some of the available technologies for evolution of broadband wireless systems, including carrier aggregation, MIMO, HetNets and small cells. Of particular interest are small cell technologies, thanks to their merits to increase system capacity. To that extent, small cells deployment aspects and a specialized case for small cells deployment in high density traffic public venues such as stadiums are addressed. We conclude with a reference to salient aspects of the fifth generation (5G) mobile networks research.
