4G** will completely change the way we work and play

Recently, several heavyweight communications operators around the world seem to have talked about the possibility of big or small movements on 4G. U.S. operators have alerted the House of Representatives because of wars over 4G and quasi-4G services, and have had to rely on the creation of new laws to regulate the market; the British government warned O2 UK companies not to use legal acts as an excuse to undermine the upcoming launch of the country. In the LTE spectrum auction, the UK regulatory agency communications office also expressed support for its proposed auction rules; SK Telecom, Korea’s largest mobile operator, announced that it will launch its 4G LTE network from July 1st to meet the needs of smartphone and tablet users for high-speed wireless networks. The demand for access, but experts have claimed that South Korea’s 4G is 3.9G... When 3G hasn’t had time to be recognized by many people, 4G is rushing again. What does 4G mean to humanity?

● 4G creates "a huge wireless ecosystem"

Scott Schneider, in his recently published book "The New World of Wireless: How to Compete in the 4G Revolution," said that when consumers just felt that they had figured out 3G wireless gadgets, they came again. It is time to master the fourth-generation wireless technology. What is 4G? He explained that the fourth-generation wireless technology will be faster and more impactful than all wireless technologies we have experienced before. Schneider predicts that 4G will completely change our working methods and entertainment methods. It will create "a huge wireless ecosystem" and "a ecosystem of innovations one after another."

Schneider further explained the "big wireless ecosystem" of 4G in an interview. 4G includes several aspects. First, it is much faster. The second major change is that new wireless technologies are more like "clouds," which means that many devices can be interconnected through different types of networks. The third major change is that things that are still happening behind the scenes will one day become very apparent. That is the connection between the items and the equipment, that is, the concept of the Internet of Things that we propose.

● China 4G is not far away Although the application of 3G in China is only a matter of recent years, the real life of 4G expatriates is no longer far away. On July 1, the relevant experts of China Mobile participating in the TD-LTE test disclosed that the current TD-LTE scale trial network conducted by China Mobile has completed the network supporting work in the province, and the first batch of system equipment manufacturers that have entered the market have completed the core The test of the network is carrying out the next phase of wireless network testing. By the end of December of this year, all vendor testing will be completed.

At the end of 2010, the Ministry of Industry and Information Technology approved the approval of China Mobile to undertake the "TD-LTE scale trial network" construction project. “2011 will be the first year of TD-LTE commercialization, and 26 TD-LTE trial networks will be established worldwide.” Wang Jianzhou, chairman of China Mobile, has repeatedly appealed for the acceleration of TD-LTE deployment.

It is reported that China's TD-LTE is also 3.9G. Professor Zeng Jianqiu of Beijing University of Posts and Telecommunications pointed out that technically speaking, this is not 4G, but 3.9G. The theoretical data transmission speed is higher than the current 3G standard and is also referred to as quasi 4G. It has application in Shanghai World Expo and Guangzhou Asian Games. After the completion of TD-LTE, it does not mean that the previous 3G and 2G networks are no longer needed. TD-SCDMA can be smoothly upgraded to TD-LTE, and some of them can even rely on software upgrades. "An important sign of the 4G era is that the speed will be at least 10 times the 3G rate, and the bandwidth will be wider." Zeng Jianqiu predicted that the real 4G era will come several years after its development.

● The 4G era peaks and turns?

Whoever has the leading communication technology can control the future. Can China become a leader one day? According to GSA data, as of April this year, the number of operators worldwide announced the deployment of LTE has reached 196. As one of the versions of LTE technology, LTE TDD technology is increasingly being favored by operators as a global solution for asymmetric spectrum. Statistics show that at present, 18 operators or government agencies in the world have conducted experiments or demonstrations of LTE TDD, and China Mobile is the main driving force for this strong growth momentum.

The market research institute In-Stat recently released the latest research report. Its wireless communications analyst Chris Kissel said that currently the US LET4G operator's investment and efforts in this technology are continuous and large-scale, so the leading advantages in global mobile communications technology will be replaced, Asian wireless operators' The technological advantage will return to the North American market. It is expected that the US LTE4G investment will account for more than 25% of the global market, and its user growth will exceed the sum of Europe and Asia.

The fourth-generation mobile communications long-term evolution technology LTE4G technology has a good momentum of development in the world. LTE4G, as an important mobile broadband technology, will be the most important wireless technology standard in the future. It is expected that the number of global LTE4G users will reach by 2014. It will exceed 150 million.

4GLTE is far from universal, but new news has been reported from Sweden. Ericsson has developed 5G technology equipment that is 10 times faster than LTE, 3GPP Release10. Experts predict that this is a very young technology and should not be out of the laboratory until 2013. Text / reporter Cao Fang ● link ●

● What is 4G?

4G is the abbreviation of the fourth generation of mobile communication and its technology. It is a technology product that integrates 3G and WLAN and can transmit high-quality video images, and the quality of image transmission is comparable to that of high-definition television. The 4G system is capable of downloading at 100 Mbps, 2,000 times faster than dial-up Internet access, and uploading at speeds up to 20 Mbps, and can satisfy almost any user's requirements for wireless services. In terms of prices most concerned by users, 4G and fixed broadband networks are comparable in terms of price, and billing methods are more flexible and mobile. Users can determine the required services according to their own needs. In addition, 4G can be deployed in areas not covered by DSL and cable modems, and then extended to the entire region.
