Wireless Networking
‒ Network architectures
‒ Multioperator Spectra Management, sharing / Spectra trading
‒ Software Defined Networking (SDN)• Decouple the control and data planes
• Enable external control through a logical centralized software entity called the network controller
• Network Functions runs as software application at the application plane
‒ Network Functions Virtualization (NFV)• Network functions are implemented independent of the physical resources and are deployed in virtualized
environments, such as mobile clouds
• Virtualize a set of network functions by deploying them as software packages in a cloud environment
• Services are available on a demand basis
‒ Mobile Edge Computing (MEC)• MEC is a key enabler for IoT and mission-critical vertical solutions.
• MEC is one of the key technologies for enabling the transformation to 5G architecture, helping to satisfy the
demanding requirements for the 5G era in terms of expected throughput, latency, scalability and automation
