China News Service Client Beijing, June 10 (Reporter Wu Tao) Recently, news about the 5G network in the 700MHz band has continued, including China Mobile and China Radio and Television 5G co-construction and sharing cooperation, several listed companies announced their participation in the formation of China Radio and Television Network Co., Ltd. Companies and so on, the focus is on the construction of China Radio and Television 5G network.

　　What does this mean and how does it affect ordinary users?

700MHz band 5G network is coming

　　Recently, according to incomplete statistics, at least 10 listed companies have announced that they have participated in the formation of China Radio and Television Network Co., Ltd., including Gehua Cable, Oriental Pearl, and Guiguang Network.

　　Many analysts believe that this means that China's broadcasting and television 5G network construction is accelerating. The broadcasting and television network companies have been separated by provinces for a long time. This integration has a great relationship with the acceleration of China's broadcasting and television 5G construction. Some netizens ridiculed: You might not believe it. If you use China Mobile in the future, I will use Oriental Pearl!

　　At the business level, on May 20, China Mobile also announced that it will carry out 5G co-construction and sharing cooperation with China Radio and Television, which includes the two parties jointly investing in the construction of a 700MHz 5G wireless network at a 1:1 ratio, jointly owned and entitled to use 700MHz 5G wireless Network assets.

　　Specifically, China Mobile will undertake 700MHz network operation and maintenance, and China Radio and Television will pay China Mobile the network operation and maintenance costs. Before the commercialization of the 5G network in the 700MHz band, China Radio and Television paid to share the China Mobile network to provide services to its customers.

　　In fact, on April 1, the Ministry of Industry and Information Technology issued a document to adjust the frequency usage plan of the 702-798MHz frequency band for mobile communication systems, and plan the frequency band 703-743/758-798MHz for the frequency division duplex (FDD) working mode. Mobile communication system. At that time, it is not difficult to see that the 5MHz network in the 700MHz band is rapidly advancing.

Why push 5G network in 700MHz band?

　　Aren't the three major operators of 5G networks already under construction? The latest news shows that more than 10,000 5G base stations are added every week. Why should we push a 5G network in the 700MHz band?

　　According to the Ministry of Industry and Information Technology, planning to use the 700MHz frequency band for mobile communication systems will provide valuable low-band spectrum resources for 5G development, and will promote the coordinated development of 5G high, medium and low frequency bands.

　　"The low frequency band below 1GHz has good propagation characteristics, which can better support 5G wide area coverage and communication experience in high-speed mobile scenarios and massive device connections, further advancing 5G multi-scenario applications." Ministry of Industry and Information Technology said.

　　Independent telecommunications analyst Fu Liang said that 700MHz may be used for 5G coverage in a short period of time, and can also solve network coverage problems in edge areas.

　　The industry generally believes that the 700MHz frequency band has low signal propagation loss, wide coverage, strong penetration, high transmission efficiency, low base station construction scale, and low network cost. Therefore, it is also known as the "gold band" and has always been coveted by various operators. Resources.

　　In addition, more than 56 countries or regions around the world have started or plan to deploy frequency division duplex (FDD) 4G networks in the 700MHz band. The 703-748/758-803MHz solution is the most widely used and fully utilized frequency planning solution for spectrum resources, and supports the evolution to 5G systems.

　　According to the Ministry of Industry and Information Technology, the use of the 703-743/758-798MHz frequency band for FDD-based mobile communication systems is compatible with mainstream global planning solutions and is conducive to sharing the global industrial foundation.

Pay attention to this when buying 5G mobile phones in the future!

　　Having said so much, what does it have to do with ordinary users? First of all, users may be able to speed up the use of China Radio and Television 5G network, even if it is not in the 700MHz band, they can also share the network using China Mobile. Don't be afraid to go abroad. China Mobile also provides international service transfer services for China Radio & TV for a fee.

　　In addition, it also involves small details of buying a mobile phone: can the 5G mobile phone you buy support 5G network in the 700MHz band? Where to look? 5G mobile phones often have instructions such as "support n41, n78" on the detailed parameters. It actually refers to which 5G band numbers are supported.

　　According to the Ministry of Industry and Information Technology, China Mobile obtained two 5G frequency bands, 2515MHz-2675MHz and 4800MHz-4900MHz, with band numbers n41 and n79, respectively.

　　China Unicom has obtained the frequency band of 3400MHz-3500MHz, the frequency band number is n78, and China Telecom has obtained the frequency band of 3500MHz-3600MHz, the frequency band number is also n78.

　　The Ministry of Industry and Information Technology plans to use the frequency band 703-743/758-798MHz for the FDD mobile communication system as n28. (The frequency band number of 703MHz-748MHz/758MHz-803MHz is n28, which almost coincides with the plan of the Ministry of Industry and Information Technology.)

　　However, the reporter observed that few mobile phones now support the n28, including the latest Huawei P40. I don't know if the follow-up mobile phone manufacturers will make up for this shortcoming. After all, after supporting 700MHz network, it is really a full Netcom mobile phone. (Finish)
