5G commercial use: antenna technology is the foundation

With the commercial use of 4G licenses in my country, as of the first half of 2015, the 4G communication network has fully covered areas above the township level. At present, the construction of mobile communication network continues to accelerate. According to statistics, as of September 2015, the total number of mobile communication base stations in my country reached 4.077 million, of which the total number of 3G/4G base stations reached 2.944 million, accounting for 72.2%. 3G/4G network services Quality and coverage continued to improve.

But this is just the beginning. LTE construction is in the ascendant, and 5G mobile communication technology has been extensively studied. my country may be the first to launch a 5G communication network, and the peak rate of 5G will reach 10G per second. The current antenna system is difficult to meet such a high network demand.

Qiao Yueshan, deputy director of the Department of Electronics of the Ministry of Industry and Information Technology, attended the meeting and delivered a speech, saying, "my country will strive to occupy an important position in the development of 5G, and at the same time, the commercial use of 5G will also strive to be at the forefront of the world. Although the antenna system accounts for the new mobile network composition The proportion is small, but as the connection of the terminal link independently, it plays an important role in the performance of the communication system.”

A few days ago, IMT-2020 currently defines new technologies such as large-scale antennas, new multiple access, high-frequency communication, ultra-dense networking, new network architecture, full-duplex, low-latency, high-reliability communication, and the Internet of Things. Among them, large-scale antenna technology, based on active antenna and 3D-MIMO technology, can greatly improve the spectral efficiency and power efficiency of wireless communication, and is the most potential research direction to support 5G mobile communication.
