In the first session of the General Assembly was held on the eve of the global 5G, it announced that its Bell Labs China to achieve a breakthrough in high-speed wireless transmission and use of millimeter-wave spectrum, by using them on a large scale in the millimeter wave band MIMO technology (Multiple Input Multiple Output technology) to achieve a significant improvement of capacity and related efficiencies. Nokia Telecommunications China Shanghai Bell, executive vice president and joint management team, responsible for Technology and Innovation Gui Luoning believes that the future 5G has six key technologies, and Bell Labs will conduct innovative research in these key technologies, so as to create great value.
Strengthen innovation in key technologies
According to reports by the peak transfer rate of more than 50Gbps prototype, Bell Labs China in the 28GHz millimeter wave band successfully up to 100bps / Hz spectral efficiency, the transmission rate allows users to complete more high-definition movies in 8 seconds download. This technique results-5G Internet network operators to achieve a tactile, low latency high-definition virtual reality (HD-VR) and other business innovation provides the foundation for future applications.
Gui Luoning According to reports, in the millimeter wave solutions, Nokia Bell Labs China with an innovative low-latency air-interface to ensure that the millimeter wave band to achieve efficient wireless transmission, improve end-user experience; through massive MIMO and beam tracking, including innovative physical layer technology to ensure the large system capacity and spectral efficiency. Ultra-high-speed transmission and high-performance millimeter-wave spectrum, allowing operators of high-speed mobile services with a better user experience, through application of wireless backhaul and other areas to achieve greater flexibility 5G network deployment.
In addition to millimeter wave technology, Gui Luoning said other key technologies in 5G Bell Labs also strengthen innovation. As the industry’s most concerned about the new air interface technology, in order to achieve future demand for all things Internet-compatible frame structure 5G empty, the waveform must exhibit great flexibility, and to automate the network on the basis of intelligence and programmable technology. Gui Luoning told reporters, Bell Labs is currently working on a new flexible frame structure, regardless of the scene is high-bandwidth, ultra-dense connections, low latency or low power, there can be adapted to flexible frame structure. In the new wave, Bell Labs has been achieved from 3.75KHz to 120KHz to business and the type of user-defined minimum air interface access unit with software-defined way.
In his view, the network delay, the new air interface can be supported from 0.125 ms to 4 ms; in broadband networks capable of rising from 20M to 1G. The new network architecture, the new air interface, large-scale antenna array technology, LTE + 5G WiFi technology as well as the formation of the low-frequency range of access, depending on the software to adjust the different types of access services.
Things are developing new unknown
Model Bell Labs Consulting shows that in 2020, WiFi is expected to meet 67% of global consumer demand, and 14% of the demand will appear with the current 3G, LTE, small base station of the popularity of new technologies and 5G be satisfied, the remaining 19% of the demand can not be met. Therefore, network operators need to accelerate the development of NFV, SDN and cloud and other 5G technologies and new business models to address the needs of scarcity.
Gui Luoning believes Things (IoT) is developing a network of new uncharted territory. By 2020, the number of devices connected to the Internet of Things is expected to be in 2014 to grow to 1.6 billion by 2020 from 20 billion to 46 billion between. Wherein the cellular networking equipment will reach 1.6 to 4.6 billion between 2020. Despite the use of large scale networking devices, sensors and video cameras but which did not have much equipment in proportion, so the cellular flow of things produced in 2020 in the proportion of total mobile data traffic is only 2%.
However, recent data obtained from the point of view, things traffic signaling traffic generated will be much higher than data traffic. For example, a typical networking device consumes 1MB traffic needs to be connected to data processing or 2500, and the same flow rate via a mobile video connection that is capable of being exhausted.
