![]() ![]() Low-band 5G uses a similar frequency range to 4G cellphones, 600–900 MHz, which can potentially offer higher download speeds than 4G: 5–250 megabits per second (Mbit/s). For providing a wide range of services, 5G networks can operate in three frequency bands - low, medium, and high.ĥG can be implemented in low-band, mid-band or high-band millimeter-wave. ![]() The increased data rate is achieved partly by using additional higher-frequency radio waves in addition to the low- and medium-band frequencies used in previous cellular networks. Millimeter-wave antennas are smaller than the large antennas used in previous cellular networks. Millimeter waves also have more trouble passing through building walls and humans. Millimeter waves have a shorter range than the lower frequency microwaves, therefore the cells are of a smaller size. Several network operators use millimeter waves called FR2 in 5G terminology, for additional capacity and higher throughputs. 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 frequencies 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 connect more devices, improving the quality of Internet services in crowded areas. The new networks have higher download speeds, with a 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 the telephone network by radio waves through a basestation and antennae 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 cellular networks, which cellular phone companies began deploying worldwide in 2019, and is the successor to 4G technology that provides connectivity to most current mobile phones.
