6G (network)

In telecommunications, 6G will be the sixth generation standard for wireless communications technologies supporting cellular data networks. It is the planned successor to 5G and will likely be significantly faster, at speeds of ~95 Gbit/s. Like its predecessors, 6G networks will be broadband cellular networks, in which the service area is divided into small geographical areas called cells. Several companies (i.e. Nokia, Ericsson, Huawei, Samsung, LG, Apple) have shown interest in 6G. China, South Korea and Japan also reportedly have interest. 6G will likely become commercially available in the 2030s.[1][2][3][4][5]

Amplifier progress

Recent studies have contributed to marked progress in the 6G industry. A group based at the University of California, Santa Barbara has claimed significant progress by building a device that can speed up the process of development and save substantial amounts of time during the design phase. They reported key aspects of the device, including an "n-polar" gallium nitride high-electron-mobility transistor (HEMT), in two papers which were published in IEEE Electron Device Letters.[6][7] The presence of this charge in the transistor gives the device the ability to operate at high frequencies, because the electrons are free to move quickly through it without obstruction. Although the data has not been published yet, the researchers claim it shows promising results, and, according to their plan, they will eventually test the new devices at even higher frequencies than before (140 GHz and 230 GHz, with both firmly in the terahertz range).[8]

Test satellite launch

On November 6, 2020, China successfully launched an experimental 6G test satellite into orbit, along with 12 other satellites, using a single Long March 6 launch vehicle rocket. The satellite will "verify the terahertz (THz) communication technology in space, a breakthrough in space communication", according to the Global Times newspaper.[9][10]
