The primary goal of previous mobile network generations was to offer fast, reliable mobile data services to network users. 5G has broadened this scope to offer a wide range of wireless services delivered to the end user across multiple access platforms and multi-layer networks.
5G creates a dynamic, coherent, and flexible framework of advanced technologies to support a variety of applications. 5G utilizes a more intelligent architecture, with Radio Access Networks (RANs) no longer constrained by base station proximity or complex infrastructure. 5G leads the way towards disaggregated, flexible, and virtual RAN with new interfaces creating additional data access points.
