frequency band of3G: TDD_ (TD-SCDMA) 1880 MHz-1900 MHz and 2010 MHz-2025 MHz.
frequency bands of4Gare 1880-1900 MHz, 2320-2370 MHz and 2575-2635 MHz.
5G Frequency and Frequency Band: V15.0.0version TS38.104 specification released in December 2017. The frequency range of 5GNR is defined as different FR: FR1 and FR2, respectively. Frequency range FR1 is commonly referred to as 5GSub-6GHz (below 6GHz) band, and frequency range FR2 is 5G millimeter wave band. As we all know, TDD and FDD are two duplex systems in mobile communication system. In4G, FDD and TDD are divided into different frequency bands. In 5GNR, FDD and TDD are also divided into different frequency bands. At the same time, new SDL (supplementary downlink) and SUL (supplementary upstream) bands are introduced.
The fifth generation mobile phone mobile communication standard, also known as the fifth generation mobile communication technology, foreign language abbreviation: 5G. It is also an extension of 4G and is under study. At present, there are no public specifications or official documents of any telecommunications company or standard-setting organization (such as 3GPP, WiMAX Forum and ITU-R) referring to5G.China(Huawei),Korea(Samsung Electronics),Japanand the European Union are investing considerable resources in developing 5G networks.
