Nowadays, the communication industry is developing rapidly. From BB phones in the 1980s to smart phones today, the development of China’s communication industry has developed from a relatively simple call and short message business at the beginning to diversified services such as Internet surfing, shopping, leisure and entertainment
I. Development status of the communication industry
At present, more than 98% of China’s administrative villages have access to optical fiber and 4G, fulfilling the national 13th Five-Year Plan ahead of schedule. Monitoring data showed that the average download rate in 130,000 administrative villages exceeded 70Mbit/s, basically achieving the same speed in rural and urban areas. By the end of September 2019, China had 580,000 fixed Internet broadband users with access rates above 1,000 Mbit/s. The number of Internet broadband access ports reached 913 million, a year-on-year increase of 6.4 percent and a net increase of 45.76 million over the end of the previous year. Among them, optical fiber access (FTTH/O) ports reached 826 million, a net increase of 54.85 million over the end of the previous year, accounting for 90.5% of the total from 88% at the end of the previous year, leading the world
Ii. Development prospects of the communication industry
China has formed an optical communication industry chain with a complete layout and a complete system, and its industrial scale continues to expand. Optical transmission equipment, optical access equipment and optical fiber and cable products have basically realized domestic production, and have a certain competitiveness in the world. Especially in the system equipment sector, Huawei, ZTE, Fiberhome and other companies have become the leading enterprises in the global optical communication equipment market.
The arrival of 5G network will spread to a wider range of civil and commercial fields. This is not only an opportunity but also a challenge for the communications industry.
(1) Strong support from national policies
The communication equipment manufacturing industry has the characteristics of high added value and high technology content, and always receives great support from our industrial policy. The 12th Five-Year Plan for National Economic and Social Development, the Guide to Key Areas of High-tech Industrialization with Current Priority Development, the Directory for Guidance on Industrial Structure Adjustment (2011), the 11th Five-Year Plan for the Development of Information Industry and the Outline of the Mid-2020 Long-term Plan, the 12th Five-Year Development Plan for Communications Industry, and the High-tech Industries with Current Priority Development The Guidelines on Key Areas of Industrialization (2007) and the Plan for the Adjustment and Revitalization of the Electronic Information Industry all put forward clear opinions on promoting the development of the telecommunications equipment manufacturing industry.
(2) The domestic market is booming
The continuous rapid development of our national economy has promoted the vigorous development of mobile communication industry. Large-scale communication infrastructure investment will inevitably drive the development of related industries. Beginning in 2010, the construction of 3G wireless communication networks, especially TD-SCDMA system, has entered the second phase. The extension of depth and breadth of 3G mobile communication network construction will bring a large amount of mobile communication infrastructure investment, so as to provide a good opportunity for the development of Chinese communication equipment manufacturing industry. On the other hand, the working frequency of 3G mobile communication is mostly between 1800 and 2400MHz, which is more than double the 800-900MHz of 2G mobile communication. Under the same power, with the development of 3G mobile communication, the coverage area of its base station at a higher operating frequency will be reduced, so the number of base stations needs to be increased, and the market capacity of the corresponding base station equipment will also increase. At present, the working frequency of 4G mobile communication is wider and higher than that of 3G, so the corresponding number of base stations and equipment will be further increased, requiring a considerable investment scale。
3) Comparative advantages of Chinese manufacturers
The products of the industry are technology-intensive, and the downstream customers also have higher requirements for cost control and response speed. Our higher education trains a large number of outstanding engineers every year to meet the needs of the industry in technology research and development. Our abundant high quality labor, developed industry supporting, logistics system and tax preferential policies also make our industry cost control, response speed advantage obvious. Technology research and development, manufacturing cost, response speed and other aspects of the advantages, making our communication antenna and radio frequency device manufacturing industry has a strong international competitiveness.
To sum up, under the background of rapid development of mobile Internet and mobile payment, modern wireless communication technology has become the main carrier of information transmission in modern society because of its unique convenience. Wireless network brings unlimited convenience to people, wireless network is gradually spread and rise, so wireless communication engineers will have a great deal to do!
