The industry consortium setting standards for 5G, the 3rd Generation Partnership Project (3GPP), defines '5G' as any system using 5G NR (5G New Radio) software - a definition that came into general use by late 2018. As in other cellular networks, a mobile device moving from one cell to another is automatically handed off seamlessly. The base stations, termed nodes, are connected to switching centers in the telephone network and routers for Internet access by high-bandwidth optical fiber or wireless backhaul connections. All 5G wireless devices in a cell communicate by radio waves with a cellular base station via fixed antennas, over frequency channels assigned by the base station. Cellphones with 4G capability alone are not able to use the 5G networks.ĥG networks are cellular networks, in which the service area is divided into small geographical areas called cells. Due to the increased bandwidth, it is expected the 5G networks will increasingly be used as general internet service providers (ISPs), competing with existing ISPs such as cable internet, and also will make possible new applications in internet-of-things (IoT) and machine-to-machine areas. 5G has higher bandwidth to deliver faster speeds than 4G and can thus connect more different devices, improving the quality of Internet services in crowded areas. The new networks have higher download speeds, peak speed of 10 gigabits per second (Gbit/s) when there is only one user in the network. All 5G wireless devices in a cell are connected to the Internet and telephone network by radio waves through a local antenna in the cell. Like its predecessors, 5G networks are cellular networks, in which the service area is divided into small geographical areas called cells. In telecommunications, 5G is the fifth- generation technology standard for broadband cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the planned successor to the 4G networks which provide connectivity to most current cellphones.
