Network Slicing

Definition

Network slicing is a technology that allows multiple virtual networks to be created on a single physical network infrastructure. This enables tailored connectivity solutions for different use cases, such as connected vehicles, by allocating specific resources and optimizations based on the requirements of each application. By using network slicing, mobile operators can efficiently manage resources and provide enhanced Quality of Service (QoS) for various services within the same network environment.
