NGMN (r)evolution of mobile radio networks

This paper provides an introduction to the NGMN (r)evolution from an operator perspective. The highly challenging performance targets that future mobile radio systems need to satisfy are introduced and explained. It is shown which means future technologies such as LTE-A provide and how these means are beneficial in achieving the overall target of persistent customer satisfaction. Exemplarily, coordinated multipoint operation (CoMP), relays and carrier aggregation are discussed showing their potential but also the complexity coming along with these features. Dealing with exponential traffic growth however, can only be overcome by a combination of new features for increased performance to be applied in combination with new deployment concepts.
