5G and Radio Access Network architecture

Radio access technologies for mobile broadband have evolved effectively to provide connectivity to billions of subscribers and things. Current Radio Access Network architecture is undergoing a transformation to increase deployment flexibility and network dynamicity, so that networks will be able to meet the performance requirements demanded by applications such as extreme mobile broadband and long-range massive machine type communication. Next generation 5G networks will cater for a wide range of new business opportunities, some of which have yet to be conceptualized. They will provide support for advanced mobile broadband services such as massive media distribution. Applications like remote operation of machinery, tele-surgery, and smart metering all require connectivity, but with vastly different characteristics. The ability to provide customized connectivity will benefit many industries around the world, enabling them to bring new products and services to market rapidly, and adapt to fast changing demands, all while continuing to offer and expand existing services. To prevent total cost of ownership from soaring, the 5G architecture will be software configurable and split between general purpose and specialized hardware, in a way that enables optimal placement of networks functions.
