5G is the fifth generation of cellular network technology. The industry association 3GPP defines any system using “5G NR” (5G New Radio) software as, “5G”, a definition that came into general use by late 2018. Others may reserve the term for systems that meet the requirements of the ITU IMT-2020.
5G is a new kind of network: a platform for innovations that will not only enhances today’s mobile broadband services, but will also expand mobile networks to support a vast diversity of devices and services and connect new industries with improved performance, efficiency, and cost.
