5G can and will serve many customers with very different needs and use cases. From use cases requiring large bandwidth and high data rate, such as AR & VR applications, to connecting thousands of end devices, to real-time communications. The so called network slicing is key to this new type of virtual network architecture. The technique of network slicing provides the several different resources tailored to specific use cases. Network slicing means that many virtual networks can be created which are adapted and optimized for the respective use case and traffic. And that even within one single network. In a public or private 5G network, this means that various user needs can be supported.
Network slicing means that the networks can be divided into many areas (slices) per use case. Each slice is optimized to provide the resources and network topology required for the particular service and traffic needs. Features such as speed, capacity, connectivity and network coverage are tailored to the requirements of individual use cases, but functional components can also be shared across different network slices.
Over time, network slicing will allow operators a higher level of programmability and will be used to address large-scale usage scenarios, such as the massive Internet of Things.
