At present, the 5G communication technology that the public hopes have just completed the first stage, and it has been a long time since it was officially commercialized. However, some people have begun to think about 6G before 5G. A few months ago, Google selected "6G" as one of the most popular words. A Fortune 500 company recently revealed its research on 6G. The Ministry of Industry and Information Technology of China even made it clear that China has begun to study 6G.
5G has not yet tasted it, I began to think about 6G? I heard that it is also related to the blockchain.
At the MWCA 2018 Mobile World Congress in Los Angeles, US Federal Communications Commission (FCC) Commissioner Jessica Rosenworcel stated in a speech that 6G will move to the terahertz (THz) frequency and introduce blockchain-based dynamic band sharing technology. In fact, from 1G to 5G in the near future, in order to increase capacity and speed, the spectrum of mobile communication is increasing, and the frequency band is getting higher and higher, and 5G has entered the millimeter wave band.
However, as the frequency band is gradually increased, its signal coverage will become smaller and smaller, and the solution is to build more base stations. Therefore, in the future, we may be surrounded by base stations everywhere. In addition, in 2015, the FCC launched CBRSD (Public Wireless Broadband Service) in the 3.5 GHz band to dynamically manage different types of wireless traffic through a centralized spectrum access database system to improve spectrum efficiency.
Members of the Rosenworcel said that CBRS is highly creative, efficient and forward-looking, and in the future, a smarter, more distributed and dynamic spectrum sharing access technology, namely blockchain + dynamic spectrum sharing, can be realized.
The blockchain is a distributed database that can be updated securely without the central intermediary. In the future, the use of blockchain as a low-cost alternative to dynamic spectrum sharing technology can be explored, which not only reduces the management cost of dynamic spectrum access systems but also improves spectrum efficiency. It is also possible to further increase the access level and access to users. He pointed out that the use of decentralized distributed ledgers to record various wireless access information can further stimulate new technological innovations and even change the way the wireless spectrum is used in the future.
