What can a 5G network do?

Some people say that 4G is enough, but it doesn't need 5G, and even the implication is that 4G is not needed. This statement is actually untenable.

The main reason for saying this is that "3G/4G was fast when it first came out". I don't understand that the "fast" experience of 3G/4G in the early days was based on the premise that the capacity was less than the upper limit.

The frequency band of 4G naturally limits the upper limit of the data stream that the 4G base station can carry. The base station can only connect a certain number of clients on the premise of promising a single connection bandwidth experience. According to the different busy hours, this number can be slightly higher than the upper limit of the total bandwidth and the divisor of the promised bandwidth of a single connection, but after all, the bandwidth limit determines that this upper limit is very low.

The radiation range of 4G base station is several times larger than that of 5G base station, and its potential connection demand is greater. Considering that its total bandwidth is much narrower, the load of 4G base station is much larger than that of 5G.

I'm already very weak, and I need to move more bricks. How much can each brick weigh?

Mobile phones, watches, computers, tablets, cars, and surveillance should all be networked ... Once the number of connections is close to saturation, the base station will allocate bandwidth-more people, less people.

The number of connections exceeds the limit. Are you going to watch 4G soon?

There is also a saying that "4G is redundant, as long as 3G is fast", and the mistakes made are the same. 3G base stations have lower capacity restrictions than 4G base stations, and the problem of connection overload is more serious.

In the case of only one or two million users, of course, it is very fast. 100 million users, you try?

In fact, you misunderstood the logic of telecom operation. In every network upgrade of telecom operation, increasing the bandwidth of a single customer is not the purpose, but the real purpose is to increase the number of network users. A slight increase in single-client bandwidth is only to increase users' willingness to access the network. In fact, telecom operators are obviously more willing to allocate the same bandwidth capacity to as many users as possible (monthly traffic), rather than giving each user enough bandwidth but limiting the total number of users.

In fact, it is very simple. Improve the single customer experience of 4G, double the price of 4G, force some customers to give up bandwidth, and the rest will be soon. You don't need to add any base stations, how simple it is!

Why is 4G to 5G different from 3G to 4G?

Because by the end of 20 18, 4G users have reached11900,000, and if 3G users are counted, the total number has reached13.3 billion.

To expand the number of users, the new users will only be IOT-that is, IOT users such as robots, drones and sensors, while human users have basically expanded to the end. Therefore, upgrading from 4G to 5G is no longer a 3G-4G mode of "increasing customers and bandwidth", but a real mode of "increasing customers and bandwidth".

People who use the experience of 3G and 4G to calculate 5G have made basic cognitive mistakes here.

It can be expected that the unit price of 5G will be greatly reduced, but the traffic itself is the main charging standard mode, rather than the current monthly mode. In this mode, customers will consciously limit their speed and use high bandwidth only when needed. But even the self-limited bandwidth will be several times that of the current 4G.

As for the feeling that "3G is fast enough" and "4G is fast enough", it is only a special experience of a few people in very few cases. After the explosive development of registered users, this experience has long ceased to exist.

Single station capacity is low. What if you want to hurry? Or simply build more base stations to realize dynamic roaming allocation between base stations.

If you want to keep the speed of 4G unchanged and keep the number of single-station connections from putting pressure on bandwidth, the number and density of 4G base stations will eventually approach the density of 5G base stations-simply losing bandwidth.

Chapter 65438 +0-5G will profoundly change the company form and labor relations.

Well, too many people are dreaming, only thinking about the influence of personal entertainment and people's livelihood services.

This is actually a "million dollar" answer. The 5G license has been issued, and the time limit is not so sensitive, but we can only simply choose the key points.

You know, an enterprise should concentrate all its employees in a place where they can work face to face. In fact, all the reasons are only due to the direct contact of physical space, ultra-high definition, no delay and ultra-stability.

You can calculate how much per capita cost a company located in Guangzhou, Guangzhou, Shenzhen, Suzhou and Hangzhou has paid for this "absolutely reliable ultra-high-definition communication without delay".

Pay the rent or difference between employees (and their families) living in the central city and living in the satellite city.

Paid the rent for the office.

Commuting cost, a big city (commuting time is actually time occupied by unpaid work).

It pays the brain drain cost of employees who have to leave and return to small cities at a certain age because they can't successfully settle in big cities-which means that they often have to recruit and retrain, and they keep losing experienced old employees.

These costs often exceed the disposable income of employees.

Tell a funny joke-for many new people in the workplace who are highly replaceable, they are not as valuable as their desks.

It is a luxury for an enterprise to coordinate all the schedules of employees in relevant departments and call people to a conference room for a meeting, which is a report burned by the deficit.

Customer's time is more precious. You can't invite customers to a meeting with the team, but the result is a high probability of getting stuck-even a 5% probability is a high probability. (It is expected that this proportion will be greatly reduced after the commercialization of 5G.) Therefore, enterprises have to gather around port cities and set up offices and R&D centers. The reason for getting together is actually to be closer to upstream and downstream enterprises and closer to customers and suppliers. Only in this way can we achieve "high reliability, no delay and super clear" communication at the lowest cost.

—— In short, the central city of Guangzhou, Guangzhou and Shenzhen is essentially just a super-large conference room.

But what is the cost of this "super conference room"?

Most importantly, it pays the opportunity cost of "unable to hire the most suitable candidate in the whole country/local time zone or even the whole world". All major central cities in the world are facing this embarrassing situation-the use of locally available talents has long lost its cost performance, and the newly added population has no skills, but the cost is high from the beginning. The same level of salary is very attractive to people with the same skill level in second-and third-tier cities, but this part of human resources can't be used, which leads enterprises to give up a lot of business. This has buried a large number of potential positions and international competitiveness.

Beishangguangshen is not only an extremely expensive super conference room, but also a "overcrowded human resources desert".

When the cost of change is lower than the constant cost, change will come, which is the dynamic essence of all social changes.

The "constant" cost has flooded the chin of enterprises, and because of the basic concept of "enterprises share social responsibility", this cost line is in danger of moving up further. Sino-US relations have cooled down, and the tension of global supply chain has expanded dramatically. China's repositioning in the global supply chain has exerted great pressure on human resources from the outside to the inside.

However, the cost of change is declining-5 G construction will become a heavy weight on the other side of the scale.

This means that the revolution of business activities will change the functional orientation of central cities.

-"But what does this have to do with 5G? 4G and fiber +wifi are not enough? "

For a project, you are the project supervisor, you are in Shanghai, your boss is talking about financing in Beijing, your chief programmer is on vacation in go to dali recently, and the customer's docking person is attending an industry conference in Shandong. Your project construction manager debugs the equipment at Party A's site and usually stays in an express hotel. How to connect them all with optical fiber?

What a coincidence! How can it be so extreme?

Perhaps, it seems extreme that all of them happen together (in fact, this is a very common thing in current business practice. If you want to say that it is extremely rare, you can only say that your industry is not so good-the more profitable the industry, the narrower the range of stakeholders will be). So if one or two of these key stakeholders can't get together, is it "extremely rare"?

It happens every day, so to speak

What is the ideal solution to the problem?

—— Several people synchronously check the pictures sent back by the on-site personnel, then switch to the scheme of the scheme group synchronously, then switch to the private chat channel of the two bosses to discuss the scheme locally, then switch to the relevant personnel to ask questions synchronously and randomly, then switch to the business personnel to explain the memo, and record the video.

A problem can be solved in two hours, and there are no hidden dangers.

The premise is that you can call this group of roles smoothly and stably. You can't keep clients and bosses waiting.

Why do you ask everyone to leave a wifi and an optical fiber? What is the probability that each of them has at least 4G links compared with the probability that all of them have high-speed optical fibers? I won't say anything else. It is extremely unlikely that there will be high-speed wifi on the project site.

But if one link in this chain is broken, there is only endless waiting. Wait until A is free, wait until B is free, wait until CD is available, wait until ABC is available, and then you find that the initial demand is distorted between layers of reporting. B thinks it's A, D thinks A says D. After the contract is signed, the engineer says "it's over" to the business and reports it to the business. Business executives really dare not ask customers to sign again-"It is estimated that no one will die, and I have already jumped ship when something happened."

Do you see it? Why does a stable and extensive wireless mobile network have to enter this era? Why is the so-called "high-speed optical fiber+indoor Wi-Fi+ unable to withstand 4G with a large number of terminals accessing at the same time"?

There needs to be a ubiquitous 5G that can withstand the access of a large number of devices-the narrow radiation range of 5G just means that it is almost impossible to "explode the access number" with its access capability. Otherwise, please ask your business manager to try to connect 4G in the customer's office building. Thousands of people fight with you in one building! There are all pedestrian streets nearby! Why not ask him to answer the customer's wifi? The customer wants you to connect to the visitor network-it's polite, and people usually don't connect you, okay? The networks of R&D center and headquarters are not allowed to connect their own people at will. Who knows if you are an expert in growing Trojan horses in the industry? Luckily, I got in touch with you. Guess how much bandwidth I left for you? Just answer it for you. Do you really dare to report it in front of the boss?

Come on, why not find a fiber +wifi6?

Optical fiber and Wi-Fi are not enough. Because modern business activities are very mobile. Decision-makers in enterprises rarely have the habit of standing by in a fixed place for a long time. A large number of enterprise businesses involve front-line staff, and there is no fixed ideal network condition. Wifi and optical fiber LAN settings are unfamiliar and unpredictable, which will bring unpredictable risks to online collaboration. When you clear the schedules of all parties concerned and find that one or two key people have connection problems, this kind of waste is unforgivable. Often have serious consequences.

4G can't solve this problem perfectly. It is precisely because of the wide radiation range of 4G that the possibility of congestion within its radiation range is unpredictable. In particular, many businesses often involve areas with high population density-such as shopping malls, stations and downtown areas. The competition of 4G bandwidth has become a serious uncertain factor. As long as there is a 10% chance of problems, it will be a disaster when large-scale coordination is needed, which will cause participants to distrust the whole model, among which customers are the most sensitive and critical. Few companies dare to take this risk casually. Therefore, 4G can only be used for one-on-one collaboration in a very small range.

Second, the future teamwork will be closer than people think, and it is not enough for simple text information and audio information, even so-called high-definition video.

I'll give you a simple and concrete scene. The ideal way for an art team using unreal engine to cooperate should be as follows: in the same scene, the person in charge of plants is adjusting the plants in the whole scene, the designer in charge of specific buildings is adjusting the buildings, the person in charge of motor vehicles is adjusting the vehicles, and the person in charge of lighting is setting the lights and constantly debugging the experience. All these people are influenced by the achievements of others. A huge tree must cross the railway bridge, and the chimney of the train must ensure that it does not touch the branches. Their ideal way of working is to work in the same scene. You can see the update you just made at any time, even if there is a certain delay, it is far better than a person working hard to complete a picture, and then save it and submit it to the scene, waiting for the supervisor or Party A to tell you that the chimney is high and the color is not harmonious enough.

Everyone and everyone synchronize the status quo of the whole project. Everyone should have their own perspective, their own decisions, and their own sub-teams should be coordinated.

Architectural design, mechanical design, software design-it can be said that any complex system design is more inclined to such a cooperative mode of "everyone is on the same page".

How much bandwidth is needed? There is no upper limit. So is this "just the special needs of some advanced enterprises, not ordinary enterprises"?

Unfortunately, if the intellectual property involved in your enterprise does not require this level of coordination. You will be wiped out by some (unmanned) basic public services in the foreseeable future, and the future is in jeopardy. The more coordination you participate in, the safer you will be.

This trend is non-negotiable, those who follow it will prosper, and those who go against it will die.

You will think that 5G bandwidth is too much for you. This does not mean that you can be happy that "I can save a lot of traffic charges", but that you should think about how to strengthen your intellectual depth. If you can't think of the answer, you will be reduced to ashes by the enterprise that thought of the answer.

On the most superficial level, whoever can make faster, deeper and better use of the new network environment with high mobility and large bandwidth can better get rid of the ultra-high land cost in China's central cities and get a 30-50% cost reduction benchmark. This is already a great comparative advantage. This advantage, whether in reducing costs or improving profits, is overwhelming or even devastating to competitors who do not have this ability.

I'll give you a simple tip, because I have to bypass some of my confidentiality needs, so I can only mention it vaguely:

1) Intelligence-intensive enterprises will quickly embrace online virtual teamwork-it is revealed that Microsoft's team has begun to support helmet-mounted virtual conference room interaction.

2) In the future, a large number of online collaboration tools, tailored new workflow, new contract framework, new human resources framework and employment model, as well as matching corporate culture and professional ethics are needed. At the management level, consulting institutions that provide business management consulting needed for form transformation will get a huge opportunity. -but this premise is that you have to lay out a few years in advance and have real cases to take.

3) In terms of market, enterprises that take the lead in completing structural innovation will begin to take advantage of this strategic advantage and attack traditional enterprises with slow change across industries. Just as internet companies attack traditional manufacturing industries with the help of internet advantages.

4) On the technical level, online collaboration tools such as worktile, teambition, trello, slack, webEX, Teams, Zoom and teamviewer will make great progress. For enterprises with weak IT adaptability, it is a major crisis in the medium and long term. Therefore, IT consulting industry and small-scale agile development team, please think about how to win the trust of customers and win the new office system orders of these enterprises.

5) In terms of hardware, the helmet-mounted virtual office environment is expected to explode in the next three to five years.

6)5G will change the distribution of real estate prices. Job opportunities in central cities do not necessarily require "living in central cities" as a prerequisite. Go online at the appointed time and just stay at the venue.

7) It will eliminate some jobs and promote others. Think about whether your position is in this ranks. Old-timers with average ability who enjoy the success just because they are "locals" must study hard and improve their strength.

I want to know what it means to you in this big change.

This will change everyone's lifestyle and can't be summarized as "downloading videos faster". For some people, time may be running out. Take action quickly.
