At present, China's 5G has been in the stage of commercial promotion, with 993,000 base stations built, accounting for more than two thirds of the world's total, and the number of 5G patent applications also ranks first. But at the same time, 6G has also been put on the agenda. Huawei, which has sufficient communication technology reserves, recently said that it will complete the 6G network in 2030.
Xu Zhijun, the rotating chairman of Huawei, said in the preface of the book "A New Journey of 6G Wireless Communication" that it is expected that 6G will be put into the market around 2030. He believes that the technical environment faced by 6G is more complicated, and cloud computing, big data, artificial intelligence, blockchain, edge computing, heterogeneous computing and endogenous security will all have an impact.
This book was written by Dr. Tong Wen, CTO of Huawei Wireless, and Dr. Zhu Peiying, Senior Vice President. It is the first systematic book about 6G wireless network, which shows the overall vision of 6G in the era of intelligent everything, and expounds the driving factors, key capabilities, application scenarios, key performance indicators and related technological innovations of 6G.
6G innovations include people-centered immersive communication, perception, positioning, imaging, distributed machine learning, interconnected AI, post-industrial 4.0 based on smart connection, smart city and smart life, and super constellation satellites with 3D global wireless coverage. The book also introduces the new air interface and networking technology, communication awareness integration technology and ground and non-ground integrated network technology, and discusses the new network architecture to realize interconnected AI, user-centered network and native trusted function.
Don't think that the 6G era is far away. Huawei has invested 6G since 20 17, and the Ministry of Industry and Information Technology has also conducted research on 6G for a long time. It is necessary to hurry up. It has always been to consolidate a generation, popularize a generation and pre-study a generation. It will be too late when other countries produce 6G results. In fact, in addition to Huawei, ZTE, OPPO, vivo and other companies have already laid out the 6G market in advance, and have organized research teams to study related technologies. It is generally expected that they will also be commercialized around 2030.
China has become the main source country of 6G patent applications. At present, there are more than 38,000 global patent applications in the field of 6G communication technology, of which China ranks first in the world, accounting for 35%( 1.3 million, or about 1.58 million). However, Lu Jianhua, an academician of China Academy of Sciences, said recently that the real demand for 6G should come from the market and focus on solving practical problems. We must avoid speculation and arbitrariness, and we cannot replace application requirements with technology trends.
A little personal thought, output determines demand, first of all, output, and then it is conditional to consider application problems. Before laying 6G, it may be too late to figure out which applications of 6G should be used. Just like when 4G was popularized, no one thought that 4G would promote the development of mobile payment and short video industry.
Anyway, wait and see.
