› New >3 GHz spectrum bands and spectrum efficiency

› Massive MIMO, increasing both spectrum efficiency and coverage

› Increased energy efficiency enabled by lean characteristics in the new standards for NR

› Network slicing enabling economic connectivity solutions, customizing SLAs to use case needs and increasing the economical efficiency through sharing of common physical infrastructure

› Open, software defined 5G system with network function virtualization

› Separation of control- & user-plane, enabling flexible network deployments

› Building compute capabilities at the edge of the network to support ultra low latency use cases and enable topology aware processing and storage

› Offload from transport networks and processing from the device
