1, Shanghai, the "Gigabit First City", once again launched 3 Gigabits. The evolution of optical network, 5G, Wi-Fi 6 and communication technology in different directions finally unified the goal: Gigabit.
2. Adding a new infrastructure sample to 3 Gigabit Shanghai smells good.
2065438+081October 24th, 10, the whole city of Shanghai was covered with gigabit optical networks, making it the largest gigabit city in the world. Since then, Shanghai has entered the Gigabit era.
2065438+On March 26th, 2009, the first batch of "Global 5G+ Optical Network Double Gigabit Demonstration Zone" was launched in Lingang Industrial Park. Shanghai has always been one step ahead in the pursuit of Gigabit.
On April 28th, 2020, Shanghai Telecom officially announced that it would upgrade 3G GB and increase the construction of Gigabit Wi-Fi on the basis of 5G+ fixed-line broadband. Shanghai once again entered the "3 Gigabit Era" with a "departure" attitude.
An epidemic, such as the same catfish, has accelerated the construction of new infrastructure. The epidemic has spawned new modes and formats such as fresh e-commerce, online education and telemedicine. Consumption upgrading has a stronger demand for high bandwidth, artificial intelligence and big data. The new economy and new life have never needed new infrastructure so much.
The "Shanghai Action Plan for Promoting New Infrastructure Construction (2020-2022)" published on May 7 (referred to as "Article 35 of New Infrastructure") clearly defines "new network" as a "double gigabit" broadband network with 5G and fixed network. Why should Shanghai Telecom further increase the concept of "Gigabit Wi-Fi"?
In the next three years, Shanghai will take the lead in building a new generation of global information infrastructure benchmark city, which requires its builders to have advanced strategic vision and open innovative thinking. As the first telecom operator in China to propose to build a "three-gigabit city", Shanghai Telecom looks to the future: the future of industrial development, the future of people's life and the future of a city, which will be a gigabit "ubiquitous" ultra-high-speed capital.
Recently, the reporter learned exclusively that on May 17, World Telecommunication and Information Society Day, China Telecom Shanghai Company (referred to as Shanghai Telecom) will announce the signing of the first batch of "3 Gigabit" users, take the lead in creating a number of "3 Gigabit" benchmarks and demonstration application scenarios, and provide best practices for the "Shanghai sample" of new infrastructure.

"Gigabit Closed Loop" of Shanghai Telecom
The evolution of optical network, 5G, Wi-Fi 6 and communication technology in different directions finally unified the goal: Gigabit.
Although the home is already gigabit broadband, Chen Ying, a Shanghai resident, is often troubled by the Internet speed of mobile phones, iPad and laptops. I didn't feel it. "Chen Ying did a test, plug in the network cable can measure the broadband network speed of 900Mbps. After being converted into a Wi-Fi signal, only 200Mbps can be measured at most.
"The previous generation of Wi-Fi 5 (IEEE 802.11AC) has been difficult to keep up with the requirements of the new era for network speed. The speed measurement shows that Wi-Fi 5 can only play 50% of the performance of Gigabit optical networks, or even lower. " Xu, a network expert in Shanghai Telecom Office, told the IT Times reporter that being limited by the old Wi-Fi technology and equipment is one of the important reasons why Gigabit optical networks are difficult to be truly perceived.
Until Wi-Fi 6 appeared.
In 20 19, IEEE (Institute of Electrical and Electronics Engineers) released 802. 1 1ax, which is a new generation of Wi-Fi standard named Wi-Fi 6 by the Wi-Fi Alliance (WFA Wi-Fi Alliance). Compared with the old version, Wi-Fi 6 has the highest transmission rate of 9.6Gbps, higher concurrency, lower delay (within 10ms), wider coverage and lower terminal power consumption. The average throughput of users is increased by at least 4 times, and the number of concurrent users is increased by more than 3 times.
Shanghai has always been willing to be the "leader" in the industrial popularization of the latest technology.
Located at No.211,century avenue, Pudong, Shanghai, the Information Life Experience Hall has just set up a brand-new exhibition area-HOL. A thin optical fiber connects all information access ports in the "home" and converts broadband signals into Wi-Fi 6 signals through the home optical fiber gateway. The IT Times reporter measured on the spot that the wireless Internet access rate of mobile phones supporting Wi-Fi6 exceeds 900Mbps.
"In theory, there is no upper limit to the bandwidth of optical fiber. After the whole house is fiberized, the future network speed will increase from Gigabit to 10 Gigabit or even higher, and there is no need to rewire. " On May 5th, Xu Jun, a national model worker known as "the first person to access optical fiber in China", reformed the all-optical network+Gigabit Wi-Fi network in a user's home. He told the IT Times reporter that it only took more than two hours to transform the network of a villa, and the wireless Internet access rate test exceeded1.200mbps..
Using optical fiber to build a brand-new home network, using Wi-Fi 6 to present the "original" Gigabit rate, the third generation communication technology entered the Gigabit era, which perfectly closed the obsession of Shanghai with "Gigabit".
The IT Times reporter learned from Shanghai Telecom that up to now, Shanghai has achieved optical network coverage 100%. By the end of June, 5G will fully build the commercial network capacity of 5G SA, basically form a competitive 5G mobile Gigabit network covering the central city and major towns, and complete the large network Wi-Fi6 Gigabit coverage of ChinaNet in a number of public places such as transportation hubs, commercial squares and tourist attractions.

"Two feet" Gigabit
"Fiber-optic broadband, 5G and Wi-Fi 6 are all communication technologies that have evolved to the fifth generation, and the three should be synchronized." Wei Leping, executive deputy director of the Communication Science and Technology Committee of the Ministry of Industry and Information Technology and director of the Science and Technology Committee of China Telecom Group, told the IT Times reporter.
Although the construction of 5G is in full swing, Wi-Fi still carries the world's major data traffic. The Wi-Fi Alliance mentioned in a report entitled "Next Generation Wi-Fi 6: The Future of Wireless Connection" that Wi-Fi carries more than half of the global data traffic. In Japan, Wi-Fi accounts for 83% of smartphone traffic, and in Germany, Wi-Fi accounts for more than 87% of all smartphone traffic.
This means that in more scenarios, Wi-Fi still has its habits and advantages that cannot be ignored.
"In the construction practice of many projects, we often encounter the situation that the mobile signal is not stable enough and the optical fiber broadband wiring is limited," said Wang Junwei, deputy director of Lujiazui Branch of Shanghai Telecom. For example, there are often some large-scale activities in Zheng Da Square, but there are shops on both sides. Previously, the use of optical fiber network was easy to bring inconvenience to the store. "If you have Wi-Fi 6, you can not only solve this problem, but also synchronize high-definition images to large advertising screens in shopping malls for more people to see."
"In addition to home applications, Wi-Fi 6 is also very useful in crowded indoor places such as shopping malls, airports, railway stations and campuses." Xu is responsible for the technical research and application promotion of Gigabit Wi-Fi. He told reporters that Gigabit technology, that is, "wireless", is more suitable for outdoor, high mobility and other places, especially in the early stage of 5G network construction. The construction price of Wi-Fi 6 is relatively low, and many technologies like 5G have greatly improved its performance in all aspects. Therefore, 5G and Wi-Fi 6 should coexist and complement each other for a long time to come. Telecom operators can quickly deploy Wi-Fi 6 to provide cities and industries with full-scene, seamless coverage of Gigabit mobile networks.
Gartner predicts that by 2023, the market size of Wi-Fi 6 will reach $5.2 billion, with a compound annual growth rate of 1 14%. At present, ASUS, ZTE, Huawei, Xiaomi and other manufacturers have launched Wi-Fi 6 routers.
In this new technological transformation cycle, the advance layout of Shanghai Telecom will undoubtedly accelerate the release of industrial dividends and play an important role as a weather vane for the industrial chain.

Stimulate consumption potential
What is more imaginative is the consumption potential stimulated by the upgrade of family Gigabit Wi-Fi.
Internet speed always makes people "it's a long story" about home Wi-Fi, which limits the popularity of consumption in many industries.
VR, which has been on fire but has never been on fire, is still difficult to get rid of the "little scorpion" on its head. According to the data, the requirement of cloud VR for game bandwidth is 80Mbps~ 1Gbps, and the delay is less than 20ms~8ms, which can really solve the problem of dizziness. After Gigabit home Wi-Fi network, not only the game response time is faster, but also people can wear lighter helmets and play mobile VR games in various rooms at home. This may promote great changes in the entire VR hardware and content industry.
After the outbreak, Shanghai clearly proposed that by the end of 2022, Shanghai should be built into a leading highland for the development of "online new economy" with international influence.
Telecommuting, online finance, online entertainment, online exhibitions, fresh e-commerce, non-contact distribution, new mobile travel, online education and other new scenes closely related to residents' lives mostly occur at home, which means that faster and more stable wireless network support is needed.
"After breaking the bottleneck of home Wi-Fi network speed, the network economy will have more ways to play. Ultra-high-speed networks bring more immersion, interactivity and real-time, and XR (augmented reality, including augmented reality AR, virtual reality VR and mixed reality MR) technologies and industries will usher in a favorable market. " Pei Zengyu, a researcher at the Center for International Public Studies at Fudan University, said.
For example, the popular 5G slow live broadcast and live broadcast with goods have a sense of scene, but the perceptual impact brought by the secondary picture is far from enough, but what if you are in the "scene"? Sitting in a hologram with VIA? Wei Leping believes that although many business models are still not perfect, the "road" must be repaired first. "There will never be a car on the narrow road. Once the road is wide, it won't be long before the car is full. "
Coupled with the 5G under construction, gigabit network transmission that can be connected anytime and anywhere will make consumers put forward more extreme requirements for the network economy and become the new potential of the new economy.

Necessities of "Shanghai sample"
Ruijin Second Street, with profound historical and cultural background, has the most beautiful urban area in Shanghai, where Sun Yat-sen, Zhou Enlai, Zhang Xueliang and Ba Jin once lived. Two-thirds of the area under its jurisdiction is located in Hengfu Scenic Area, with 68 historical protection buildings.
"We should take good care of these' antiques'," said Miller Wen, director of Ruijin Second Sub-district Office. In this year's work plan, new technical terms such as high-speed network, Internet of Things and artificial intelligence have appeared. In the past, when dealing with "garbage classification", Ruijin Second Street cooperated with Shanghai Telecom to intelligently supervise "garbage timely delivery", which provided valuable reference for the protection of street historical buildings. "What technology can do is to find and warn in advance.
In the planning, the ultra-high-definition camera will "slowly broadcast" the renovation process of old buildings, and use AI technology to warn the violation of the Regulations on the Protection of Historical Sites and Excellent Historical Buildings in Shanghai; At the same time, use the sensor to "appreciate" the spring warmth and summer coolness of the old house, and let the century-old building "tell" new stories through big data.
This year, Shanghai further promoted "one network office" and "one network unified management". The municipal government clearly put forward that it is necessary to display the panoramic view of the city in a digital way, rely on technical means for intelligent management and efficient disposal, intelligently and accurately predict and prevent potential risks, strengthen the construction of "neuron" perception system, and comprehensively grasp the basic signs of urban operation.
In the "35 Articles of New Infrastructure" of Shanghai Edition, four key areas are defined: the construction of "new network" with a new generation of network infrastructure as the main body; Construction of "new facilities" focusing on innovative infrastructure; Build a "new platform" based on comprehensive infrastructure such as artificial intelligence; Construction of "new terminal" based on intelligent terminal infrastructure.
"Running the city like embroidery" requires the joint efforts of these "new forces" and a gigabit network covering the whole city.
Optical network, 5G, Wi-Fi 6, 3g Shanghai, it smells good.
