5G will radically change networks by 2020 through virtualization, network slicing, and distributing data and services to edge networks located closer to users. This will allow customized network slices for different needs like autonomous vehicles requiring low latency. 5G will enable new applications and transform industries like smart cities, transportation, healthcare, and manufacturing by providing the network connectivity and capacity needed. Security will also need to evolve for the new 5G architecture and proliferation of connected devices.
