5G Key Technology Research Direction

For domestic mobile communication users who have not yet experienced the charm of 4G mobile communication, 5g may still be spent in the mirror, in the fog of the moon; but for the scientific research field, 5g research has already begun, Samsung announced in May, the first 5G core technology-based mobile transmission network was developed to achieve 1 Gbps data transmission rate per second.

What is 5 GB? What is its core? What are the research directions of Key Technologies? What changes will it bring to our lives?

The core of 5g is network convergence.

5G makes up for the shortcomings of 4G technology and further improves system performance in terms of throughput, latency, connection quantity, and energy consumption. It adopts the digital full IP technology to support and group exchange. It is neither a single technological evolution nor a few brand new wireless access technologies, instead, it integrates new wireless access technologies and existing wireless access technologies (WLAN, 4G, 3G, 2G, etc.) to meet different needs by integrating multiple technologies, is a truly integrated network. In addition, due to the convergence, 5G can continue to use 4G, 3G infrastructure resources, and achieve coexistence with 4G, 3G, 2G.

Huawei CTO Tong Wen said that 5G will provide super-capacity bandwidth, and the short-distance transmission rate is 10 Gbps, which is 100 times the current LTE. Due to the integration of various network technologies, 5g can also break the limitations of existing spectrum resources to achieve full spectrum communication. More importantly, by integrating multiple wireless access solutions, 5G technology will completely bring human society into the network society to achieve the interconnection of everything.

Driven by user demand, the number of connected devices will increase by 100 times in the next ten years, and the mobile data traffic will increase by 1000 times. In this context, 5g not only needs to meet ultra-high-speed transmission requirements, but also needs to cope with the large-scale growth of network devices and the different network requirements of different application scenarios, it meets the requirements of ultra-high capacity, ultra-reliability, and anytime, anywhere access.

5G Key Technology Research Direction

To meet the demand for access anytime and anywhere, 5g is inseparable from the support of key technologies such as network system architecture, wireless networking, wireless transmission, new antennas and RF, and the development and utilization of new spectrum, therefore, the research direction is also focused on these aspects.

5G wireless network architecture and Key Technologies

The core of 5g is undoubtedly the convergence of heterogeneous networks. Different from the previous mobile communication technology, the integration and application of technologies need to be considered. The network architecture also has more complex requirements, the following technologies need to be studied: new network architecture supporting high-speed mobile interconnection, high-density, new distributed collaboration and self-organizing networking, and joint allocation of heterogeneous system wireless resources.

Key 5G wireless transmission technologies

5G integrates existing wireless technologies to achieve a total rate of 10 Gbps. In addition, 5g research is inseparable from other new wireless transmission technologies, especially the technical bottlenecks involved in large-scale collaboration, it includes new key technologies such as wireless transmission, array antenna, and low-power RF.

5G mobile communication system business Application Technology

5G is proposed to meet the surging network traffic in the future, regarding 5g business applications and needs, business development models, user experience models, network evolution and development strategies, spectrum requirements, and air interface technical needs, the Research on Signal Propagation Characteristics, measurement and modeling for 5G spectrum applications is also an important direction.

5G mobile communication test and verification technology

The progress and development of communication technology are inseparable from the progress of communication testing technology. The emergence of 5g means that the parameters, precision, and methods to be tested have all changed. Therefore, it is necessary to study the evaluation and testing methods of 5G mobile communication networks and wireless transmission technology, and establish a 5G mobile communication network simulation test and evaluation platform and a Transmission Technology Simulation Test and Evaluation Platform.

What changes does 5g bring to life?

Technically, 5g is suitable for high-speed data transmission, high-population areas or occasions, and high-speed mobile communication, the transmission rate of nearly 10 Gbit/s means that users can transmit a large number of data files without restrictions, instantly download a whole hd movie, and enjoy ultra-HD content such as 3D movies and games and real-time streams. In other words, 5G will allow mobile users to enjoy wireless Internet access experience similar to the current home optical fiber network.

In terms of capacity, transmission rate, accessibility, and reliability, 5g has leap over the previous mobile communication technology. Although 5G will not be commercially available until 2020, carriers in many countries have already begun deployment, and many scientific research institutions and organizations have also conducted relevant research. With the in-depth technical research and the accelerated standardization process, 5G will truly fly into ordinary homes.
