Performance analysis of the key aspects affecting capacity of 4G LTE networks

This paper provides a thorough analysis of the key aspects affecting the capacity of LTE networks. We group the analysis to the three major categories namely technology, spectrum and topology aspects. Through the extensive system-level simulations we investigate which of the specified aspects mostly affect the capacity and spectrum efficiency of 4G LTE networks. In addition, based on the performed analysis we discuss on what solutions are most likely to be realized in the near future to support continuously increasing mobile traffic demands.
