The 5G Spring Festival is here. On the 10th, the Spring Festival transportation curtain opened, the realization of 5G signal coverage of the Guangzhou-Shenzhen-Hong Kong high-speed rail formally put into the Spring Festival transportation, has become our country 5G construction development in the application landing another milestone event. All say 5G changes society, the new year, this kind of change is happening.
On the 10th, the first day of the Spring Festival, this year's Spring Festival Movement achieved a historic breakthrough, with the 5G signal-covered Guangzhou-Shenzhen-Hong Kong high-speed rail into the Spring Festival, the first 5G Spring Festival.
The guangshen-hong kong high-speed rail 5g coverage project was created by guangdong mobile in conjunction with guangxi railway group and Huawei, starting in september 2019. Due to the high density of daily trains in Guangzhou-Shenzhen-Hong Kong high-speed rail, the railway department itself production task is tight, the construction of 5G coverage of tunnels and stations along the line can only be carried out late at night, and finally in a relatively short time before the Spring Festival.
“There are three scenarios for the 5G coverage of high-speed rail in Guangzhou, Shenzhen and Hong Kong. Guangdong mobile sources told reporters.
It is reported that in the railway scene, the planning and construction of more than 300 5G signal base stations along the Guangzhou-Shenzhen-Hong Kong high-speed railway line, realizing the merger of 12 equipment residential areas, thus reducing the frequency of switching in the high-speed train movement and providing a more stable coverage effect; while in the station scene, the Guangzhou-Shenzhen-Hong Kong high-speed railway passes through six stations, such as Guangzhou-South, the large station platform and station hall, has a dense flow of people and large capacity, covering through the 5G distributed Pifei station, which is more than the traditional indoor distributed base station.
There are two main models of 5G network construction, one is NSA and the other is SA. NSA is a \"non-independent network\" that relies on the existing 4G base station and 4G core network for the construction of 5G network.
NSA is based on the current 4G network construction, so it is better to deploy, the construction cost is relatively low, but in the use of the effect, this 5G network cannot reflect the low delay, slicing operation and other characteristics, SA is the opposite, the construction cost is high, but the use of good results.
Since the second half of last year, the three major carriers have taken the lead in laying some of the 5G networks through the NSA, but with the arrival of 2020, the choice of 5G network construction will also change.
Guangzhou-Shenzhen-Hong Kong high-speed rail can be said to be the first test in this respect. Guangdong Mobile said China Mobile's 5G network construction this year will move towards the SA network, and the 5G signal of the Guangzhou-Shenzhen-Hong Kong high-speed rail is still being optimized, with a 5G network upgrade expected to be completed before the Spring Festival to better support the \"5G smart high-speed rail \"application.
“Shenzhen will build up a total of 10,000 base stations in 2020, taking the lead in realizing the full coverage of 5G infrastructure and independent networking throughout the country, and implementing application demonstration projects such as Intelligent Internet Connected Automobile to create the city with the most active innovation and the most abundant application scenarios. On January 8, at the eighth session of the sixth session of the Shenzhen Municipal People's Congress, the Shenzhen Municipal Government looked forward to it.
Looking across the country, Tang Xiongyan, chief scientist at China Unicom's Network Technology Research Institute, said China Telecom and China Unicom had built a shared 5G wireless access network to achieve NSA sharing and control deployment of the NSA, with SA as the target, starting the evolution of the network to SA in the first quarter of 2020.
On September 9,2019, China Unicom and China Telecom signed the 5G Network Co-construction and Sharing Framework Cooperation Agreement. Under the cooperation agreement, China Unicom will work with China Telecom in the nationwide targeting of 200 MHz 5G band (3400 MHz -3600 MHz) to build a 5G access network.
Just a few days ago, the Ministry of Industry and Information Technology issued a license to China Radio and Television Network Co., Ltd.(hereinafter referred to as \"China Radio and Television \") to use the frequency band 5G test frequency, agreeing to deploy the 5G network in 16 cities such as Beijing. The move heralds the official acquisition of 5G frequency rights.
Compared to the three major operators in the 5G sector is in full swing, radio and television 5G progress is very little seen in the newspaper. On November 23,2019, China Radio and Television opened its first radio and television 5G base station in Changsha and the world's first 700 MHz 5G base station.
In late 2019, China Radio and Television Chairman Zhao Jingchun revealed that radio and television 5G would be officially commercialized in 2020. Time to 2020, radio and television will also usher in their own 5G network construction really start the year.
It is understood that in the development of 5G, China Radio and Television will base itself on the resources of 100 million cable television home users throughout the country, and promote the development of radio and television differentiation with wired wireless coordination, including radio and television communication coordination, communication and monitoring coordination, and it will cooperate with the State Grid Company in the field of 5G.
“In terms of networking and co-operation, radio and television networks focus mainly on the combination of industry and scene rather than mass base stations and personal consumer services. Radio and television network related people said to reporters. This is why China Radio and Television has begun to work with the State Grid Corporation.
“SA is a fully independent 5G core network, is a 5G target architecture network, with 5G large bandwidth, low delay, wide connection network capabilities. Using SA network slicing and MEC technology can greatly reduce network delay, improve service deployment agility and high service reliability. With the large-scale deployment of SA network this year, it will enable the whole industry to innovate applications, detonate vertical industry applications and achieve the vision of'changing society'. Analysis by Cai Weiwen, General Manager of Guangdong Mobile Planning Technology Department.
In addition to co-operation with Guangzhou Railway, Guangdong Mobile is also cooperating with China Southern Power Grid, Shaogang,Huawei, TCL and Midea in the vertical field.
It is reported that in 2019, the country opened a total of 10,000 5G base stations, according to the Ministry of Industry and Information Technology's goal,2020 will strive to achieve all prefecture-level cities across the country to cover 5G network. (Reporter Yao Pai)
