China's 5G promotion group officially released the "5G Network Architecture Design" white paper at the first global 5G conference on June 1, which reflects the latest achievements of China's 5G network technology research, which means that China's research from the 5G concept has entered The stage of substantive advancement - 5G is really coming.
In the terms 3G, 4G, 5G, etc., "G" is an abbreviation for the English "GeneraTIon" (the xth generation). In other words, 5G literally means the 5th generation mobile communication technology. There are many video users on the 4G network, and the video consumes a lot of bandwidth, so 5G will soon become a necessary technology. The first generation is analog technology; the second generation realizes digital voice communication; the third generation is the well-known 3g technology, characterized by multimedia communication; the fourth generation is the 4g technology that is being rolled out, and its communication rate is greatly improved, the logo Entering the era of wireless broadband.
China Unicom has been more active. At present, China Unicom has given a 5G planning timetable. It plans to complete the key technology layout of the 5G end-to-end network architecture and complete the 5G OpenLab construction to meet the 5G service demonstration and single-point technical performance verification. It is expected to realize Unicom in 2020. 5G network commercial.
Some analysts believe that in the 4G era, with the advantage of the policy of giving away, China Mobile has already been riding the dust, and China Telecom and China Unicom can only follow and warm up. But when it comes to 5G, there will be no more standards for different networks. The same 5G standard will be used globally. The technology and standards will have the true right to speak. If China Mobile leads again, Telecom Unicom has little chance of catching up, and even the ability to compete will be very reluctant.
The final 5G standard has not yet been determined in the industry. Bill Smith, president of AT&T Network Operations, predicts that the exact definition of 5G will be finalized in 2018, and then the International Telecommunication Union (ITU) will develop the 5G standard in 2019. The standard will clearly define what the “5G†network should look like, as well as key performance indicators such as the uplink and downlink rates.
According to recent preliminary experiments in the communications industry, we can still get a general idea of ​​what the future 5G technology will be. In short, compared to 4G, 5G will have faster network speeds and lower power consumption. So we will see a range of new wireless products, such as more smart home devices and wearable computing devices.
In theory, 5G's network speed can reach 40 times that of 4G, which can transmit 8K resolution 3D video in real time, or download a 3D movie in 6 seconds. In contrast, downloading via a 4G network takes 6 minutes. However, in the development of communication technology in the past, there will always be a big gap between the laboratory situation and the real environment. The theoretical peak rate is only a dream in the actual use of the user, and the user available rate is much lower than the theoretical value.
In simple terms, 5G will be faster and consume less than 4G, bringing a new range of wireless products. Li Zhengmao, vice president of China Mobile, once said that the telecom equipment in the 5G era has been greatly reduced: "In the 4G to 5G era, the transmission cost per bit has been reduced by 1000 times. Then we also hope that the price of telecom equipment will also be reduced by 1000 times. The cost is determined by the operators. The key to profitability in the data age."
Although any generation of technology development cannot be a repetition of the previous generation of technology, if the new generation of technology is the same as the previous generation technology, then what is a new generation, so 3G technology is different from 2G, 4G is different from 3G, its technical principle The way to solve problems, the way to deploy, and the ability to achieve are different, but there is no foundation for the previous generation of technology, or the next generation does not inherit the technology of the previous generation, and the revolutionary upgrade is also a castle in the air. The 5G era has arrived! Who has more opportunities for China Mobile, China Unicom and China Telecom? We will wait and see!
