China Radio and Television Zeng Qingjun

Build an ubiquitous network and achieve high-quality development

Zeng Qingjun, deputy general manager of China Radio and Television Network Group Co., Ltd., said that compared with the other three major operators, the biggest difference between China Radio and Television is content.

focuses on the characteristics and advantages of the industry and positiones the new 5G network of national cultural communication. Zeng Qingjun said that China Radio and Television will consolidate the integrated planning and construction of national and provincial responsibilities, and improve 5G load-bearing capacity; adhere to the IP, fiberization and intelligence transformation and upgrading direction of cable TV networks, and gradually realize unified technical standards; promote the evolution of the end-to-end service system of integrated networks, promote multi-screen interaction, large screens connect small screens, and small screens back to large screens; gather special channels and high-quality content, create authoritative releases, realize precise delivery, and enhance the value of single users.

China Radio and Television has always promoted the development of 5G broadcast technology in the world. 5G broadcast technology has broadcast and multicast. The NR broadcast network does not perceive users and does not need to access the network. It can receive broadcast content in idle states. That is to say, users can receive TV programs without inserting SIM cards. This is a cross-operator technology. Multicast requires the network to sense users and need to enter the connected state to receive data.

Zeng Qingjun pointed out that 5G NR broadcasting is a technology that China Radio and Television focuses on 3GPP. Its biggest feature is that it does not change the base station hardware of 5G mobile phone R15, but receives broadcast signals through software upgrades. The 5G NR broadcast service entrance uses APP as the main method, covering a rich video resource, including live channels, interactive videos, VR videos, 360-degree panoramic videos, etc.

It is understood that China Radio and Television has two transmission methods for 5G NR broadcasting. One is to use radio and television transmission towers, such as the Oriental Pearl, Beijing Radio and Television transmission tower, etc., to put 700M on the tower and use 5G technology to transmit the TV signal. As long as the 5G mobile phone is updated, it can also receive broadcast signals without a SIM card. At present, pilot projects of radio and television transmission towers in many places such as Beijing, Nanjing, and Shanghai have been completed, achieving long-distance and large-scale signal coverage, and revitalizing radio and television transmission towers and station resources. The other is broadcast signal based on 5G cellular base stations, which is mainly 480,000 5G base stations jointly built and shared with China Mobile for broadcast signal transmission. Through broadcasting, everyone can experience high-definition videos with no lag, no congestion, broadband VR, and 360-degree high-definition videos.

During this year's Winter Olympics, China Radio and Television achieved coordinated coverage of 5G broadcast signals of multiple Winter Olympic venues such as the Bird's Nest Stadium, Water Cube, National Stadium, National Speed ​​Skating Stadium, Wukesong Stadium and National Alpine Skiing Center through radio and television towers and cellular base stations. 5G NR radio provides new live broadcast services such as multi-camera perspective and 360-degree panoramic perspective for viewers in the Winter Olympics.

In addition, China Radio and Television has built a national emergency broadcast central-level platform based on 5G and cable TV networks to enhance emergency broadcast service means, expand coverage, and improve service quality. Download software on your mobile phone to respond to emergency broadcasts, which is very efficient. At present, China Radio and Television is building an emergency broadcast network covering the whole country, which is also a major measure to combine 5G and content.

Finally, Zeng Qingjun said that China Radio and Television will create a radio and television 5G network integrating content, network, wired, wireless, large screen and small screen, providing differentiated services and bringing a better experience to Chinese 5G users and cable TV users.

China Tower Dou Li

Technology innovation empowers new digital infrastructure

Dou Li, director of the technical department of China Tower Co., Ltd., said that as of the end of March this year, China Tower has undertaken a total of 1.391 million 5G construction needs.In order to undertake the demand for 5G construction, China Tower has focused on innovation in three aspects: First, reduce the cost of existing transformation. Up to now, 97% of the 5G base stations undertaken by China Tower are achieved through sharing existing resources. China Tower has carried out a series of innovations in improving the capacity of existing resources by reducing the cost of existing resources. Second, it is to control the cost of new towers. China Tower has carried out a series of innovations around building new towers, room divisions, and power supply products; Third, it has carried out a series of innovations around saving operating costs, including electricity costs. Through a series of innovations, China Tower has served several telecommunications companies and jointly created the Chinese speed of 5G construction with several telecommunications companies, so that my country's 5G construction continues to lead the world.

Dou Li specifically introduced the innovative cases of China Tower in his speech. For example, in response to the problems of high 5G frequency band, large loss and difficult coverage, China Tower has increased innovation and developed and launched a new 5G leaky cable with internationally leading coverage performance, and launched two patented technologies for tower independent intellectual property rights. The first technology is a high-frequency optimization technology. By optimizing the radiation performance of 5G high-frequency bands, it makes the cable leakage propagation more balanced. The second technology is segmented coupling technology, which distributes more energy to the cover edge by gradually troughing the leakage cable, and the coverage distance is longer. Through a series of innovations, the new type of leaky cable coverage distance is more than 1 times higher than the previous leaky cable, which reduces the investment in 5G tunnel coverage by more than 50%.

It is worth noting that in order to give full play to the unique resource advantages of China Tower's 2.1 million site, China Tower is accelerating the evolution and upgrading of the "communication tower" to the "digital tower". Through this evolution, China Tower hopes to further expand the sharing articles and enrich the sharing connotation.
