The Evolution of Wireless Networks
The need to satisfy the exponential growth of mobile data traffic has led mobile operators worldwide to become more aggressive in purchasing radio spectrum. Even then, that’s not enough. Therefore, optimizing the usage of radio spectrum has become the primary goal for mobile operators. Having a scalable and simplified network strategy in place is important to deliver the best Quality of Service (QoS) at the lowest Total Cost of Ownership (TCO)
Mobile operators are now exploring options such as convergence, Radio Access Network (RAN) Virtualization and Software-Defined Network (SDN) to reduce operational and capital expenditures (CAPEX & OPEX), minimize network complexity and optimize the usage of spectrum. In this article, we will discuss these in more details.
