5G is here!The golden band is shining!

It may be a historic day for China Radio and Television and even the entire China communications industry.

At 10 am, China Radio and Television announced that 5G network services were officially launched. This marks that China Radio and Television has really realized communication services after taking 3 years of 5G licenses

In the operation of services, the Chinese communication service market has also moved from Sanzudin to the top four. On the same day, 5G of radio and television 5G also officially launched the official website and announced to the outside world

After the content and price of the 5G package, the price of 5G most concerned about users is settled. At this point, China Radio and Television officially opened its own communication operation

Business "career".

In fact, in early June, China Radio and Television also released the three major brand logos and slogans of "China Radio and Television", "5G of Radio and Television", and "Radio and Television Huijia".

The houses of radio and television business halls have also appeared in the new radio and television 5G LOGO. In less than a month, a series of major actions. It is not difficult to see that after three years of brewing, 5G of radio and television 5G has been ready to go.

█ Starting from zero, steadily fight: the preparation process of 5G radio and television

The enthusiasm of the attention of all sectors of society has always been high.

In fact, as early as the national issued 5G licenses, radio and television and the 700MHz band it owned were hot topics in the communications industry.

Earlier in 2019, when the news came out in the workshop, when the radio and television was about to enter the construction and operation of 5G networks, it once aroused the industry in the industry.

Wave. Many people exclaimed that the pattern of China's communication industry may be changing.

Later, the news came true. On June 6, 2019, China Radio and Television and China Mobile, China Telecom, and China Unicom were awarded 5G commercial use from the Ministry of Industry and Information Technology.

The license has become a member of the domestic 5G operator.

Since then, people's attention to 5G radio and television has continued to increase. Everyone has been guessing how the radio and television 5G starts from scratch. Radio and television

Whether it is capable of completing the 5G network and whether it will pose a threat to the three major operators.

In May 2020, the mystery was finally unveiled, and China Radio and Television and China Mobile officially signed a 5G co -construction sharing cooperation framework agreement.

According to the agreement, the two parties will jointly invest in the construction of a 700MHz 5G wireless network at a ratio of 1: 1 to jointly use 700MHz 5G

Line network assets. The two parties will give full play to their respective advantages, carry out resource sharing and co -construction, and speed up the construction of 5G networks in an efficient approach.

In other words, the cooperation between radio and television and mobile will form a "2 V 2" competitive pattern with Telecom Unicom to jointly compete for the domestic 5G market.

Since then, 5G of radio and television 5G has officially entered the implementation stage, clarified the network planning plan, and organized several tenders. Bidding projects include 5G base stations,

It also includes core network platforms, business systems, and customer service systems, which will attract the close attention of the industry each time.

Some bidding project information

According to the information revealed by Song Qizhu, chairman of China Radio and Television Song Qizhu at the World Telecommunications Day Conference in May this year, in 2021 China Radio, Film and Television and China Mobile have completed

The construction of 200,000 700MHz base stations in county and rural areas. In 2022, the construction of 280,000 base stations in the central urban area will be further completed to achieve townships and towns

The above areas are continuously covered and extended widely to the administrative village. It also said that the national radio and television 5G release operations can be achieved as soon as possible with the support of all parties.

In short, three years, the 5G construction work of China Radio and Television seems to be methodical, but it is fierce.

█ Gold frequency band, obvious advantage: 700M infinite value

The core advantage of 5G radio and television 5G is its own 700M frequency band. For a long time, the 700M frequency band has been considered as a golden rice bowl of China Radio and Television, which is operational

The golden band in the eyes of the business.

Why is 700M so important?

This starts with the basic characteristics of radio waves.

Mobile communication is the technology of using radio electromagnetic waves to communicate. Different frequencies have different physical characteristics.

Everyone has learned a formula in the physical class of middle school: the speed of light = wavelength × frequency. The speed of light is a constant value, 300,000 kilometers per second. In other words, none

The wavelength and frequency of wire electromagnetic waves are inverse proportions. The higher the frequency, the shorter the wavelength.

The electromagnetic wave with a short wavelength will be poor, the signal is easily blocked by obstacles, and the transmission distance is shorter.

This means that the transmitting signal of the base station, the higher the wireless electromagnetic wave, the shorter the signal coverage distance, and the smaller the coverage area.

At present, the 5G bands used by China Mobile, China Telecom, and China Unicom are mainly 2.6GHz and 3.5GHz bands. Give by an equipment dealer

The data of each frequency band is compared as follows:

Single stand -alone stations under the same upward edge rate (5Mbps) comparison radius comparison

It can be seen that the coverage of the 700M frequency band is significantly farther, and rural areas can even reach 4.66 kilometers.

As we mentioned earlier, Radio and Television built 200,000 5G base stations in 2021, and 280,000 stations will be built in 2022, adding up to 480,000 stations. Other

The operator must build the zero head of the base station, but it is the characteristic of 700MHz, allowing 480,000 700MHz base stations to achieve full coverage of 5G networks.

According to the industry, the coverage of a single 700MHz 5G base station is about three times that of 3.5GHz 5G. This is a huge competitive advantage. Pick

Building 5G with a 700MHz band will save a lot of capital costs (equipment, sites, electricity bills, labor, etc.), and significantly reduce network construction and operation and maintenance costs. Therefore, it is called the golden band.

It is worth mentioning that because the wavelength of 700MHz is longer, for high -speed moving objects, the same angle of incident is the same as Doppler, and

That is to say, the negative impact of the Doppler effect is smaller. For high -speed moving scenes such as high -speed rail and highways, the 700MHz band can reach better

Signal quality.

This powerful coverage is also obvious to the changes brought by the user terminal. In theory, under the same prerequisite, the mobile terminal

The better the signal quality, the higher the transmission efficiency, the lower the power consumption, and the terminal standby and use time will increase accordingly.

█ Light dressing, post -hair advantage: 700MHz mode innovation

Based on the 700M band resources, China Radio and Television is based on a co -construction sharing agreement for 5G construction. It is a major innovation in the operating model. 5G radio and television

It does not need to take the old road of "heavy assets and long cycles" of traditional operators, but has chosen a new way for "light assets and fast operations".

This platform -based platform -based operation model will greatly reduce investment and avoid the risk of operating later in construction. Radio and television can be in such a short time

The realization of 5G number in the middle is benefited from the solid foundation laid by this innovative model. In the future, this model will also help radio and television 5G to achieve long -term holdings

Continuous high -quality development has formed a unique competitive advantage.

As we all know, since the third telecommunications industry reorganization in 2008, the three major operators of mobile, telecommunications, and Unicom have been formed in China. This

The pattern has continued to this day, it has been 14 years.

The addition of radio and television is undoubtedly a re -activation of the entire communication industry. We need such fresh blood, with a "challenge

The attitude of the "person entered, breaking the existing pattern and activating more innovation.

And there is no old network for radio and television, and there is no historical burden. It will be easier to paint on a piece of white paper. Co -construction sharing with China Mobile

The construction cost of hardware has been greatly reduced, and it will be more conducive to the introduction of new technologies and architectures for radio and television.

Of course, for ordinary consumer users, a wider 5G signal coverage also gives more people in remote areas to enjoy the opportunity to enjoy 5G services.

For corporate customers, radio and television 5G also has a strong attraction. Based on the high -quality network of rapid deployment of 700M, the radio and television can be shortened

Business deployment duration and new business as soon as possible.

From a macro perspective, for equipment vendors and industry chains, the addition of emerging operators will bring more demand and orders, surrounding 700M

The new industry chain can stimulate the further development and prosperity of the industry, making 5G cake larger.

█ Content operation, business integration: the long -view goal of 5G radio and television 5G

5G in the game is not as simple as building a network.

According to the 5G development plan of China Radio and Television, you can see a large blueprint for construction: "IP, cloud, intelligent, intelligent, and integrated" technology evolution

The direction, as well as the network construction target of "cloud network collaboration, solid shift fusion, advanced function, controllable, controllable". These are based on China Radio and Television themselves

The media content attribute advantages are built, and the final purpose is to build a full -fusion business body of "mobile phone+TV+broadband+voice+satellite+x"

Tie.

In addition, there is another killer in radio and television. It is understood that the new 5G NR broadcast format developed by radio and television innovation is leading the world

Standard evolution. Reliated by the 700MHz 5G network to build a national broadband cluster command system, it has also been approved.

The excavation of 5G application scenarios for radio and television not only updates the product form, but also extend to the in -depth integration of basic forms, organizational forms, and even channel ecology.

combine. With the "seamless" fusion of ground data TV broadcast networks, 5G networks, and wireless broadband networks, radio and television will develop end -to -end IP transmission,

Comprehensive wireless new form and new business.

In terms of platform construction and TOB applications, radio and television are actively exploring and increasing progress. They promoted the 5G application platform and the country of radio and television

Major projects such as the Industrial Internet Security Platform and the Specialty of the Chinese Academy of Science

Radio and television 5G application case.

With the official opening of the 5G service of the radio and television 5G service, the radio and television network will use the Lord to support the integration of the media, serve cultural and people's livelihood, and promote the development of the digital economy.

The important role of Lijun and main channels. In the digital transformation of all walks of life, 5G also has a lot of room to play, and the prospects are expected.

█ Conclusion

Of course, the official launch of the network service of the 5G of radio and television is only the first step in the long journey.

The construction of a communication basic network is a long -term process. Xiao Zaojun needs to remind everyone that it is necessary to look at the network experience of 5G of radio and television 5G rationally.

Give them more time. It is believed that over time, 5G of radio and television 5G will definitely develop rapidly, bringing users a more satisfactory experience and service.

After the radio and television 5G sailing, what kind of wonderful performance will it bring, let's wait and see!
