Over the last couple of years, we have been witnessing the process of convergence between wireless and wired networks, under intense technological innovation and rapid market evolution. Mobile operators are trying to maintain a leading role in the market as it evolves towards integration with the Internet. However, the development of a multitude of new services will require the growth of a whole new market for network connectivity, applications and content. In order to understand the business opportunities arising and the ensuing competitive dynamics, this chapter explores the evolution of key players’ business relationships and strategies along with a range of critical issues that will be faced by companies and regulators alike.

The fifth generation of mobile communications networks (5G) is currently in the standardization process, which is expected to be completed in 2020. For this new generation, new applications and scenarios are imposing new performance requirements in addition to higher data rates. Specifically, the Internet of Things (IoT) and e-health applications have very important economic roles in 5G networks and define particular performance requirements that must be considered when defining the technologies for 5G networks. In this paper, the author discusses the influence of e-health and IoT applications on the technological trends for 5G networks.

This paper investigates blocking probabilities obtained from multidimensional truncated Poisson distributions. For blocking probabilities typically arising in layered cellular mobile communications networks, the large deviations results of Gazdzicki et al. [9] are extended to state spaces determined by multiple constraints. The results yield asymptotically exact expressions that provide an accurate approximation of probabilities up to 1%, which considerably extends the applicability of large deviations results and enables efficient approximation of blocking probabilities for realistic mobile communications networks.
