Scientific and technological developments for domestic mobile communications users not experience 4G mobile communications in terms of charm, 5G perhaps Flower in the Mirror, mist month; but for the research community, 5G studies have departed, Samsung announced in May, pioneered the development of The first mobile transmission network based on 5G core technology was implemented to realize a data transmission rate of 1Gbps per second.
What is 5G and what is its core? What are the key research directions? What changes will it bring to our lives?
The core of 5G is network convergence
5G makes up for the inadequacies of 4G technology and further improves system performance in terms of throughput, latency, number of connections, and energy consumption. It adopts digital all-IP technology, support and packet switching. It is neither a single technological evolution nor several new wireless access technologies, but integrates new wireless access technologies and existing wireless access technologies (WLAN, 4G, 3G, 2G, etc., is a truly integrated network by integrating multiple technologies to meet different needs. And, due to convergence, 5G can continue to use 4G, 3G infrastructure resources and achieve coexistence with 4G, 3G, and 2G.
Huawei CTO Tong Wen stated that 5G will provide super-capacity bandwidth, and the short-distance transmission rate is 10Gbps, which is 100 times that of current LTE. Due to the convergence of multiple network technologies, 5G can also break the constraints of existing spectrum resources and realize full-spectrum communication. More importantly, 5G technology can completely eliminate human society through the integration of multiple wireless access solutions. Bring it into the network society and realize the interconnection of all things.
With the drive of user demand, the number of networked devices will increase by a factor of 100 over the next decade, and mobile data traffic will grow by a factor of 1,000. Under this background, in addition to meeting ultra-high-speed transmission requirements, 5G also needs to deal with the large-scale growth from networking devices and different application scenarios to meet different network requirements, satisfying high-capacity, ultra-reliability, and anywhere Accessibility and other requirements.
5G Key Technology Research Direction
To achieve the need for anytime, anywhere access, 5G is inseparable from the support of key technologies such as network system architecture, wireless networking, wireless transmission, new types of antennas and radio frequency, and the development and utilization of new spectrum. Therefore, the research direction is centered on these developments.
5G Wireless Network Architecture and Key Technologies
The core of 5G is undoubtedly the convergence of heterogeneous networks. It differs from previous mobile communication technologies. It needs to consider the integration and application of technologies. Its network architecture also has more complicated requirements. It is necessary to study the following technologies: The new type of high-speed mobile interconnection is supported. Network architecture, high-density new distributed collaboration and ad hoc networking, and heterogeneous system wireless resource joint deployment technologies.
5G wireless transmission key technologies
To achieve a total 10Gbps service rate, 5G incorporates existing wireless technologies. In addition, 5G research can not be separated from other new wireless transmission technology research, especially the need to break through the technical bottlenecks involved in large-scale collaboration, including large-scale collaborative configuration of wireless transmission, array antennas, low-power configurable radio and other new key technology.
5G mobile communication system business application technology
5G is proposed to meet the future surge in network traffic, 5G service applications and requirements, business development model, user experience model, network evolution and development strategy, spectrum requirements and air interface technology requirements, signal propagation characteristics for 5G spectrum applications Research on measurement, modeling and modeling are also important directions.
5G mobile communication test and verification technology
The advancement and development of communication technology can not be separated from the progress of communication test technology. The emergence of 5G means that the parameters, accuracy, and methods that need to be tested all change. Therefore, it is necessary to study the evaluation and testing methods of 5G mobile communication networks and wireless transmission technologies, and establish 5G mobile communication network simulation test evaluation platforms and transmission technology simulation test evaluation platforms.
