Why should 5G networks be divided into B?

This is because it has different rate limits in different frequency bands, otherwise it will be very stuck at that time. If you are troublesome, I wish you a happy life!

Because although the 5G network is relatively fast and fast, there will be a certain delay line sometimes, so it is necessary to distinguish it.

1.Challenge 1: Security Security is the primary issue facing industry applications.

In the 4G era, wireless public networks have not really entered the core areas of the industry, such as industrial production control, rail transit control, real-time telemedicine, etc., and various industries have solved them in the way of wireless private networks, local area networks, and wired networks. Although the wired method is more reliable and secure, the cost is too high, especially in scenarios where a large number of terminals are accessed. In terms of wireless, it is limited by the limited carrying capacity of the licensed frequency band and the security risks of the unlicensed frequency band.

2.Challenge 2: Network Uplink Enhancement The network uplink enhancement problem is a common problem of 5G in the To-B field. After delving into the needs of the industry, I.

Because of the 5G network, he must be divided. Social networks and military networks, so he scored both. Social networks are given to the usual. The user sent it, but the financial network belongs to the military.

The 5G network is divided into to B. I feel that it may be because the 5G network does not have full coverage now, because there is no way to use Wi-Fi in some places, or only the original 4G or even 2G.

Basic Concepts 1to b, b refers to == business==, Chinese means business, enterprise;

2.to c, c refers to customer, Chinese means consumer, user;

Typical examples: 1) The company's internal business support management platform is a to B product;

2) Enterprise management software, team collaboration software such as Worktile is a to B product;

3)**, e-commerce shopping platforms such as Tmall belong to C products.

Yes, the 5G network is to be differentiated, because it is not the same as the 4G network, there are many kinds of lines.

Because of the 5G network, it is a more complex problem, and it is a multifaceted technology. combined, so he wants to divide it like this, not a single combination of one network.

Because the 5G network also has to distinguish a certain network history, and it is also divided into several types, it is also divided into fast and slow, so it is said to separate this kind of thing.

This is based on his speed, and the way he runs, so it's clear.

The main thing is to distinguish the speed of the network, and then it will be divided into levels, and there is no other role.

If you want to score, it must be if the 5 rounds just came out, then he must need a certain amount of time to engage in this kind of thing.

Because the digital currency first produced by blockchain technology has had a huge impact on the financial field, the research and application of blockchain technology has become an important task in the financial field today.

The 5G network refers to the current Internet café of 5G, and the 5G network is particularly fast.

Why should 5G networks be divided? TOB should be distinct, otherwise how can it be called an unconnected network?

Why should 5G networks be divided? TOB, because his supply network is clearly divided, he can see it clearly, because the 4G network is different.

Why does the 5G network divide this, you can look at some situations on the Internet, or look for some news about 5G on this mobile phone.

Maybe it's because their network isn't necessarily fast, you can look it up.

Due to the huge impact of the digital currency first produced by blockchain technology on the financial field, the research and application of blockchain technology has become an important task in today's financial field. In essence, blockchain technology is still a kind of technical means and tools, and its application in the financial field and in the field of the real economy are parallel, with their relative independence, but also a certain degree of intersection, that is to say, the promotion of the real economy is indirect. 1. Whether financial or physical, one of the bases of the transaction between supply and demand is trust.

With the further popularization and wide application of blockchain technology, enterprises and enterprises, or individuals and individuals can self-organize the issuance of digital currency (digital credit) in the future, and the status of banks will change from the current monopoly operation to equal competition in the market. Therefore, the impact of the widespread application of blockchain technology in the financial field on the real economy is indirect. 2. Blockchain technology is the bridge between reality (entity) and virtuality, and the real world can be reconstructed, reconstructed and redefined in the virtual world through blockchain technology.

For example, the digital currency of real banknotes in the virtual world, the digital transaction in the virtual world, the digital settlement, digital customs clearance, digital documents, bills, etc. in the virtual world of real import and export, which can greatly improve the efficiency of the business process and save the cost of the transaction. At present, all transactions are inseparable from banks, banks play a central role in transactions, and the application of blockchain technology by banks will certainly improve the efficiency of their settlements, which indirectly promotes the efficiency of the real economy, but this impact will gradually weaken in the future. Because the biggest feature of blockchain technology is decentralization, its distributed ledger system is a decentralized network system.

3. The application of blockchain technology is actually the valorization and creditization of the current Internet flow of information, and the information in the Internet (use value, exchange value, cultural value) is reorganized and newly constructed to form the value Internet through the blockchain, which is of great significance.

Zhang Yunyong, president of China Unicom Research Institute, said that the main problem facing the construction of 5G networks lies in funding. Compared with the 4G network, the unit price of 5G wireless base station equipment is high, the high frequency of 5G makes the site more dense, the location of new sites is difficult, and the demand for transmission network is large for 5G large bandwidth, and the cumulative investment in 5G will reach one trillion yuan, about 4 times that of 4G.

It has become inevitable to coordinate and integrate the resources of the whole society and jointly build and share the construction of 5G networks. Zhao Dachun, deputy general manager of China Mobile Communications Group, proposed to carry out 5G network construction with "innovation, coordination, green, openness and sharing", Zhang Yunyong suggested that we should consider increasing the co-construction and sharing of 5G networks, try to avoid duplicate construction of network infrastructure, save overall network investment, alleviate the huge financial pressure that 5G network construction will face, and accelerate the pace of commercialization of 5G. Industry sharing reduces costs and improves efficiency.

In the future, a large number of 5G services and traffic will occur indoors, but compared with the mainstream 4G frequency band, the 5G frequency band is higher, and the transmission loss and penetration loss are increased, making it more difficult for signals to reach the indoor from the outside. At the same time, since traditional passive chambers only support 1T1R or 2T2R, in order to meet the high-capacity requirements of 5G, it is necessary to upgrade to 4T4R or higher-order MIMO, which will greatly increase the complexity of engineering implementation.

If technology needs to improve, it needs to be shared with others and let people suggest improvements.

The internet itself is all about sharing.

5G should be necessary for sharing.

Because the current sharing technology is very developed.

If technology needs to improve, it has to be shared with others.

The 5G indoor will face new renovation and construction, the scale of the project is large, and it needs to support higher and wider 5G frequency bands and more MIMO, and the equipment cost of the new digital room division will naturally be higher, resulting in an increase in the total indoor investment in the 5G era.

Because 5G networks, especially wireless except for radio and all core networks, need to use SDN, NFV and cloud to achieve more reasonable sharing and management of resources, so the resource pool can be sliced to achieve slicing

The Internet has made people's lives easier, and now I don't have to go out to buy things, order food, or even go to the company for work. The reason why there has been such a big change, is because the current network technology is very developed, in the past, the 2G network can only be played, the 3G network can be loaded, the 4G network can watch TV, and now the 5G network has appeared, not the frequency and speed of the network are much faster than the 4G, when building the base station, it is necessary to make great changes to the original 4G, do you know how many kilometers the base station of the 5G network is built a?

The specific installation density is not qualitative, here let's estimate according to the standard of 3G, at present, 5G base stations are mainly laid in urban areas, and the network demand in urban areas is greater, about one kilometer, about one kilometer in the suburbs, and some in rural areas, the base station density is about five kilometers.

There is an introduction to this aspect on the Internet, because of signal problems, its coverage area is small, from 2G to 4G It seems that the coverage area is getting smaller and smaller, which is an inevitable development, so it needs more base stations than 4G.

Because the frequency of the band used in 5G is high and the wavelength is short, and the transmission distance is shorter than that of 4G, it is necessary to build more base stations than 4G.

The 5G network has established many base stations in order to make the 5G network popular, and there are multiple base stations, which proves that there are more people available, more people available, and more people are tried, and finally it becomes the mainstream or even the only one.

Let me talk about it, mainly the requirements for 5G speed and popularization.

First, as a new technology, 5G technology must be popularized and must require the support of corresponding hardware equipment, and the base station is the most basic one.

Second, 5G technology should provide such a fast speed, the number of base stations must be large, because the law of radio signal attenuation is the same, in order to achieve the purpose of rapid communication, it is required to access the base station as close as possible, so it is also required to have more base stations and more power.

First of all, the frequency of the 5G network is much faster than that of the 4G network, but the larger the frequency of the base station, the faster its attenuation will be, so the density of the base station is denser than the original. So far, the three major operators have made their own general deployment, the density of the base station of Unicom home is about 3 to 4 times that of the original, the mobile home has reached about six times, and the telecom home is also more than three times, although the current signal antenna has made great progress, but based on the high frequency decay intensity, the number of base stations laid is indispensable.

Because there are many mobile phones now, if there are fewer networks and base stations, it will not be enough, so it is necessary to design more before it can be used.

The spectrum of 5G is much higher than that of 4G, and the 4G of the three major operators is mainly concentrated nearby, and according to the 5G spectrum plan, the total 200MHz bandwidth is most likely to be equally divided between China Unicom and China Telecom, and may be allocated to China Mobile. According to the attenuation formula, the greater the frequency, the greater the attenuation, it is expected that the density of Unicom and Telecom's 5G base station will be more than 3 times that of 4G, and the density of mobile base stations will be 6 times that of 4G, even if 5G has a revolutionary optimization of antennas and radio frequency, it is expected that the base station density of Unicom and Telecom is 2 times that of 4G, and the mobile one is slightly greater than 3 times. In fact, in the central area of the city and the suburbs, the density of the base station has a large number of overlapping coverage areas, remove this part of the overlapping area, 5G coverage of the central area of the city needs about 200-300 meters of a 5G base station, the suburbs about 500 meters -1 km about 1 5G base station, the rural area needs a kilometer of a 5G base station.

There are so many networks to be established, which shows that there are many people who use the Internet in today's society.

The propagation capacity is very poor, and the higher the frequency, the faster the attenuation.

I don't know, I said I asked.

The network has built many base stations in order to popularize the 5G network, and there are multiple base stations, which proves that there are many people available, and there are many people available.

Why is only Huawei able to do 5G SA networking, and what is the difference between NSA and SA networking?

The main reason is that in the SA networking mode, the 5G network and base station are completely independent of the previous 2G, 3G, and 4G.

The NSA networking mode is upgraded on the basis of the existing 4G network, with little investment.

1. In 2019, the NSA will be the mainstay, and the SA will be piloted, and in 2020, it will evolve to the SA, and the international mainstream frequency bands will be adopted initially.

2. Among them, NSA is a non-standalone network, which refers to the deployment of 5G network capabilities using existing 4G networks. SA stands for standalone network, which refers to a 5G network that is built separately.

3. Among the 5G mobile phones currently on the market, some mobile phones support both NSA and SA, and some mobile phones only support NSA. In the future, NSA and SA networks will coexist, and there will be no situation where NSA phones will soon be unusable. Phones that support SA at the same time support NSA.

In order to quickly solve these problems in the early stage, this is the NSA mode networking.
