When will China Unicom pilot 5g network open? How fast will 5g network go on the market

Four seas network: Recently, China Unicom and ZTE opened the first 5g test point in Shenzhen, with a test speed of 2gbps. The first 5g new airport base station in the outfield marks the coming of the 5g era. When will the 5g era be commercially available? Let's take a look at it!

According to the report 5g in China: outlook and regional comparison released by China Academy of information and communication on the 29th, 5g business will be realized in China in 2020, and there will be 428 million 5g users in 2025.

According to Wang Zhiqin, vice president of China Academy of information and communications, as of the end of April 2017, China's 4G users had reached 849 million, accounting for 62.9% of mobile users, with explosive growth in mobile traffic.

The report predicts that in the early 5g network personal consumption market, enhanced mobile broadband (embB) will be the core application scenario, and 5g's main services after commercial use will include applications based on 4K / 8K Ultra HD video, augmented reality (AR) and virtual reality (VR).

Pan Feng, deputy chief engineer of Institute of industry and planning of China Academy of information and communication, thinks that in order to meet the needs of such high bandwidth applications, the core goal of 5g in the early stage will be to expand the capacity of wireless network and divert the pressure of 4G network, so as to meet the increasing demand of mobile broadband data flow. There may be some new terminal types in 5g era, but it is expected that smart phones will still be the main terminal types in the early stage of 5g business, and the pricing of early 5g smart phones may be higher than 4G due to key factors such as chips and RF modules.

Technical index

The landmark capability index is "Gbps user experience rate". A group of key technologies include large-scale antenna array, ultra dense networking, new multiple access, full spectrum access and new network architecture. Large scale antenna array is one of the most important technical means to improve the spectrum efficiency of the system, which will play an important supporting role in meeting the capacity and rate requirements of 5g system; ultra dense networking can achieve a hundred times capacity improvement by increasing the deployment density of base stations, which is one of the most important means to meet the capacity growth requirements of 5g; new multiple access technology can transmit signals by superposition To improve the access capacity of the system, it can effectively support the needs of 10G network equipment connection; the full spectrum access technology can effectively alleviate the huge demand of 5g network for spectrum resources by effectively using various spectrum resources; the new network architecture based on advanced technologies such as SDN, nfv and cloud computing can realize a more flexible, intelligent, efficient and open 5g new network centered on users.

Obstacles exist

The first is regulation and licensing. Fixed network and mobile network have a long history of different supervision and operation licenses. For example, in many countries, fixed line operators were the first monopolies with similar carrier and pricing restrictions. For example, the broadband capacity wholesale to Internet service providers is regulated by the state. Others rely on spectrum resources allocated by the state.

Next is the organization. In many cases, mobile operators are controlled by fixed network operators or their subsidiaries. The integration of fixed and mobile networks needs to be re examined by the country's competition authorities. Competition authorities are more likely to operate separately than in a merger. There are also different strategies of the enterprise, for example, Vodafone is completely dominated by mobile business. The other is that the shareholders of network operators are very resistant to the merger when they think of the entanglement between layoffs and labor unions or the collision of corporate culture after the merger.

Other barriers include standards. The open standard of technology interoperability is very important for the telecom industry. Standardization also needs extensive efforts and cooperation. Now there are different standards organizations in mobile and fixed network fields 3GPP and ETSI are very successful in mobile standardization. ITU-R is very authoritative in spectrum allocation. ITU-R has been put into the network standardization requirements of imt-2020 (5g) technology.
