China Has Launched the World's First 6G Satellite

World's first 6G satellite launched by china On November 6, They successfully launched a Long March 6 rocket and sent a payload of 13 satellites into orbit.The satellite uses Terahertz waves that could send data at speeds several times faster than 5G.Terahertz communication is one of the key technologies in the development of sixth-generation networking system. It went Into Orbit Along With 12 Other Satellites From the Taiyuan Satellite Launch Center from the Shanxi Province.The satellite, known as Tianyan-5, is a remote-sensing satellite jointly developed by the University of Electronic Science and Technology of China, Chengdu Guoxing Aerospace Technology, and Beijing Weina Xingkong Technology.Tianyan-5 launched aboard the Chinese-built rocket with Earth-observing satellites from the Argentinian company Satellogic.In a sun-synchronous orbit, the satellites will provide high-resolution images covering 1.5 million square miles (4 square kilometers) a day with high enough resolution to discern individual trees in a forest. 

The satellite could help stop illegal-logging in forests and manage crop disasters.It involves use of high-frequency terahertz waves to achieve data-transmission speeds many times faster than 5G is likely to be capable of.Terahertz waves, which are submillimeter waves sitting between microwave and infrared light on the electromagnetic spectrum, have been used to achieve data rates greater than 100-Gbps. Unfortunately, Terahertz waves share an Achilles’ Heel with the millimeter waves used in 5G(FIFTH GENERATION). Water vapor in Earth’s atmosphere is a strong absorber of Terahertz radiation, limiting the range of THz applications. The same issue continues to slow the widespread development of 5G, and will likely hinder the rollout of 6G if it uses Terahertz waves.The telecoms industry is still several years away from agreeing on 6G's specifications, so it is not yet certain the tech being trialled will make it into the final standard.
