Balance control is a very challenging technology development project in the field of artificial intelligence and robotics because it requires very high demands for sensor data acquisition and command transmission. Under the guarantee of the ultra-low delay characteristics of the 5G network, the precise control of the robot is likely to be placed in the cloud, which not only ensures the control effect, but also greatly reduces the cost, making further extensive application possible.
We have some understanding of the industry's expectations for 5G, but when we entered the 2016 China International Information and Communication Exhibition, we were still shocked by the industry's enthusiasm for 5G.
At the moment when 4G technology is widely popularized, 5G has reached a critical period of technology development. Therefore, although the 5G commercial era has not yet arrived, at this year's communication exhibition, 5G has become the main battleground for all parties, whether it is the three basic operators, or major equipment suppliers such as Huawei, ZTE, Ericsson, and Nokia. The 5G latest technology achievements were exhibited in large size and great efforts, and the 5G card position war was launched in advance.
At the Huawei booth, 5G has gradually moved from concept to product. Huawei demonstrated the two evolution directions of the 5G network, three core technologies and four deployment architectures, and explained the evolution of the future 5G network in a comprehensive way. It also showed the 5G high-frequency and low-frequency prototypes of the 64T64R. Since the beginning of this year, Huawei and Deutsche Telekom have released the industry's first 5G end-to-end slicing prototype, and together with China Mobile, completed the world's first high-low frequency hybrid networking side verification, and together with Vodafone completed the 5G ultra-low latency air interface test based on CloudRAN. verification. With the completion of the testing of 5G key technologies and the launch of 3GPP standardization, Huawei expects 5G to be gradually commercialized around 2020.
Not long ago, ZTE successfully completed the 5G wireless side key technology test of China's 5G test. In this test, ZTE took the lead in verifying the key technologies in the 5G high frequency and low frequency fields, and successfully passed all the tests of several air interface key technologies including high frequency, new multiple access, new waveform, Massive MIMO and so on. In this exhibition, ZTE's â€œSpeed â€‹â€‹Networkâ€ exhibition area, the audience experienced the most cutting-edge 5G core technology. ZTE has launched an upgraded version of Pre5GMassive MIMO2.0, which achieves 2Gbit/s speed after 16-stream and 3-carrier aggregation, bringing unprecedented speed experience to people. At the same time, ZTE's 5G high-frequency prototype base station also made a wonderful appearance.
5G is the most important theme of mobile communication giant Ericsson's participation in this exhibition, including 5G prototype, 5G plug-in, quasi 5G core network, 5G virtual reality auto-driving, 5G cloud robot and 5G drone, etc. . Among them, Ericsson and China Mobile Guangdong and Sun Yat-sen University demonstrated the world's first real-world automatic driving and remote-controlled driving. The demonstration site shows the driving of the vehicle in different scenarios in the automatic driving and remote driving modes. For example, in the automatic driving mode, a car located on the campus of Zhongshan University 2,200 kilometers away is used to carry out automatic path finding and avoiding obstacles. Visitors in the Beijing exhibition hall can pass two screens, respectively, from the driver's perspective and the car. Look at the car's travel from an outside perspective. Also, the UAV network will be a key to the future 5G battlefield, and Ericsson believes that the 5G end-to-end delay can be reduced from 50ms in the LTE network to 15ms. It is reported that Ericsson cooperated with China Mobile Jiangsu Wuxi Branch to conduct 5G drone test in Wuxi. This test is part of the national 5G special science and technology project. It is also the world's first UAV to pass 5G technology on the carrier's cellular network. Verification is an important milestone for 5G technology.
In the "Leading Innovation, Serving China" exhibition area, Nokia and Shanghai Bell rely on 5G technology to showcase the auto-driving scene of the Internet of Vehicles. Utilizing the characteristics of 5G technology, the reaction delay of driverless cars can be reduced from the previous 50ms to 3ms, which improves driving safety and greatly reduces the accident rate. At the same time, the data shows that autonomous driving will increase the traffic density by more than 4 times, reduce pollution emissions by more than 10%, and improve the livable environment of the city. In addition, through the demonstration of the Industry 4.0 robot, participants can also experience the advantages of 5G short delay and high reliability. At the same time, the strong support from 5G makes life more colorful. The 5G multi-connection and large-scale connection technology demonstrated by Nokia and Shanghai Bell at the site has improved the network capacity, realized a large-capacity connection of a single base station, and ensured high reliability and robustness, making the network drop in the past. At the same time, the excellent low-latency characteristics of the mobile edge computing MEC have already helped China Mobile to provide multi-angle real-time broadcasts at the Shanghai Circuit. Moreover, this technology can also be used in special object scenarios such as unmanned driving with high latency requirements, as well as industrial control and other fields. In addition to the above solutions, Nokia and Shanghai Bell also showed AirscaleBBU, FastMile, AdvancedHetnet equipment wall, small base station, 1830FrontHaul mobile prequel and so on. These programs and products have revealed to the participants the fact that a new life in the future must be an interconnected society where Internet access can be made everywhere and everywhere.
There are also three major operators that are gradually improving their independent innovation capabilities and are actively taking action in the 5G field.
At this exhibition, the audience on the China Telecom booth can watch the real-time status of data transmission of 5G analog equipment. The large-scale antenna technology (MassiveMIMO) in this exhibition is a phased achievement of China Telecom. It is reported that from the recent 2018, China Telecom will continue to carry out in-depth 5G network evolution framework and key technology research and technical concept verification, propose 4G to 5G evolution technology solutions according to their own needs, grasp the technical development and standard direction, and timely develop some key technologies. Laboratory tests and field tests.
In China Mobile's 5G exhibition area, the audience can experience the 5G three typical application scenarios of â€œEnhanced Mobile Broadbandâ€, â€œLarge Connection Internet of Thingsâ€ and â€œLow Time Delay and High Reliability Communicationâ€. China Mobile is also launching chip-based samples and 3D-MIMO commercial products based on narrow-band Internet of Things for the first time. The audience can experience the IDC cloud inspection robots and virtual reality/augmented reality motion games independently developed by China Mobile, and feel the upcoming Internet of Everything in advance. era. It is reported that China Mobile has advanced its layout and led the 5G demand, and actively promoted the development of 5G standards, technical verification, industrial chain construction and product maturity. The establishment of the 5G Joint Innovation Center has brought together 42 partners including equipment manufacturers and vertical industry manufacturers, focusing on six key work areas: basic communication capabilities, Internet of Things, Internet of Vehicles, Industrial Internet, Cloud Robotics, and Virtual/Augmented Reality. To jointly promote the development of 5G innovation.
In the future communication segment, China Unicom will showcase a number of leading-edge technologies and devices based on 5G networks, including Massive MIMO technology that can support 5G big data rate transmissions greater than 10Gbps, and flexible implementation of different regional differentiated services for future new base station implementations. Demand for 5G virtualized base stations.
