Case Study Engineering Efficiency The Background The explosion of mobile data usage confidently predicted for the last 10 years has finally arrived, driven by the uptake of the latest generation of Blackberry, iPhone, and Android devices and their app stores, and fueled by flat-rate data tariffs. The excess capacity that has been dormant in UMTS networks for some years has been consumed and high data usage also impacts voice performance, requiring operators to focus on optimization and capacity enhancements to preserve network quality for all users. The Challenge Facing this continued explosive growth in data usage, which in turn was driving a program of RNC and site expansion, a region of a major tier 1 operator needed additional engineering resource to execute the expansion pro
