The document discusses the concept of 5G mobile networks. It notes that new mobile generations have emerged every 10 years, with 5G expected by 2020. 5G networks will utilize nanotechnology, cloud computing, and an all-IP platform. Key aspects of 5G architecture include the nanocore for controlling devices at the nanoscale, cloud computing for flexible resources, and a flat IP network for universal access. Beam division multiple access allows beams to be allocated to each mobile station for increased capacity. 802.11ac is an interim step providing speeds up to 1.35Gbps to help enable a 5G "Star Trek" world.
