This paper describes capacity drivers for next generation networks and covers a method into effectively designing these networks to meet the capacity requirements without sacrificing reliability or increasing cost. In the first part of this white paper, we will examine each of these services and its capacity contributions and in the second part, we explore how the combination of these services affect the network backhaul design. Separately we will do an analysis of a typical network and how to dimension the network capacity to be able to adequately handle current demand as well as some factor of future growth. The analysis will cover the optimal approach to designing a network that can scale with evolution and perform organically to extend its useful life for as long as possible.
