5G

5G is the next-generation cellular standard after 4G. It has been defined across several global standards bodies, including the International Telecommunication Union (ITU), 3GPP and ETSI. The official ITU specification, International Mobile Telecommunications-2020, targets maximum downlink and uplink throughputs of 20 Gbps and 10 Gbps, respectively; latency below 5 ms endpoint to RAN; and massive scalability, although initial deployments may be less ambitious. New system architecture includes core network slicing and edge computing.
