5G NR (New Radio) is a radio access technology (RAT) developed by the 3rd Generation Partnership Project for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G networks.
Frequency bands for 5G New Radio (5G NR), which is the air interface or radio access technology of the 5G mobile networks, are separated into two different frequency ranges. First there is Frequency Range 1 (FR1), [1] which includes sub-6 GHz frequency bands, some of which are traditionally used by previous standards, but has been extended to ...
Background. 5G succeeds 4G LTE wireless technology. Developments have been focused on enabling low- latency communications, and promises of a minimum peak network speed of 20 gigabits per/second (20 times faster than the equivalent on 4G LTE networks), and uses within Internet of things and smart city technology.
A cellular network or mobile network is a telecommunications network where the link to and from end nodes is wireless and the network is distributed over land areas called cells, each served by at least one fixed-location transceiver (typically three cell sites or ).
In telecommunications, 6G is the designation for a future technical standard of a sixth-generation technology for wireless communications. It is the planned successor to 5G (ITU-T IMT-2020 ), and is currently in the early stages of the standardization process, tracked by the ITU-T as IMT-2030 [1] with the framework and overall ...
StarHub. Retrieved 2021-09-08. The non-standalone mode of deploying 5G focuses on enhancing existing mobile broadband to provide higher data-bandwidth and reliable connectivity on a 2.1GHz spectrum. Standalone 5G works on an independent network designed and deployed solely to enable 5G on a 3.5GHz spectrum.
