5G is coming, do we still need to install broadband? Why?

When people are discussing whether 5G will replace home broadband, on June 25th, 65438, the first 5G wireless home broadband community in China has settled in Chengdu, with a network speed of over 400Mbps.

Characteristics of 5G Home Broadband

5G home broadband linearity

5G home broadband is still in the experimental stage and has not been commercialized. It takes a while to enter the ordinary home users for two reasons:

abstract

5G is coming, do we still need to install broadband? I think it is necessary to install broadband, which is more stable than wireless network and has better signal coverage.

Compared with 4G networks, the biggest advantages of 5G networks are large capacity, high speed and low delay. The speed of the 5G network can reach above 1Gbps, and it only takes about 10 second to download a movie with the size of 1G, so the download speed of the 5G network can be comparable to the general broadband network speed.

5G networks all use high-frequency wireless electromagnetic waves. The characteristic of high-frequency electromagnetic wave is that it can transmit more data, that is, the download speed is faster, but its disadvantage is poor penetration and small coverage. Therefore, in order to achieve the expected coverage effect, 5G networks need to build more 5G base stations to enhance signal coverage, which means that operators need to invest more money. However, at present, there are too few mature commercialization of 5G networks, and operators will not actively build networks.

The tariff standard of 5G network is still unknown. Although some operators claim that the unit price of 5G traffic is cheaper than that of 4G traffic, the network speed of 5G is faster, the traffic used increases invisibly, and the tariff of 5G is more expensive, so it is not suitable for applying for broadband.

This is my opinion. The 5G network is coming, and broadband analysis is still needed.

The 5G network is coming, and broadband still needs to be installed. After all, broadband is the main force of the current network, and all walks of life, work, industry and so on are inseparable from wired broadband. 5G has just started and there is still a long way to go.

This year, the 5G network can be called "online celebrity network". Everyone knows the new times network. It is said that the speed is as high as 10Gbp/s and the delay is close to zero. It is said that the cost of 5G is high and the price is expensive, but the speed is super fast, which is still worth looking forward to.

For various reasons, it will take a long time for the 5G network to reach the mature stage. Let me explain in detail why we need to temporarily install broadband.

First, understand the next 5G network.

5G is the fifth generation mobile communication technology, and 5G is the new generation cellular mobile communication technology. The goal of 5G network is high speed, low delay, energy saving, cost reduction, system capacity improvement and large-scale equipment connection.

The biggest advantages of 5G network are: ① the data rate is fast, as high as 10Gbp/s, which is 100 times faster than that of 4G network; ② The network delay is lower than 1 ms, while the current 4G delay is 30-70 ms, which is several times lower than the 4G network delay. It only takes 1 second to download a 2-hour HD movie.

Second, learn more about broadband networks.

Broadband is a network that transmits communication signals through physical network cable or optical fiber, also known as wired network. It is the most widely used network in all walks of life. Because the signal is transmitted through the network cable, it has many advantages such as strong anti-interference ability, small signal attenuation and high speed.

Broadband access network mainly includes optical fiber access, copper wire access, optical fiber/copper wire hybrid access, wireless access and so on. At present, most of them use optical fiber, the speed is at least 100M, and the maximum download speed is 12.5Mbp/s, which can meet the needs of our daily life and work.

Third, the 5G network has just started this year, and it will take a long time to reach maturity and universal use.

1. The construction of Hong Jizhan needs a lot of manpower, material resources, funds and time.

Want to use 5G network, because 5G network is wireless transmission, so we need to use wireless transmission equipment, that is, Hong Jizhan, which is also a common signal tower. The construction of Hong Jizhan is not a small project, which requires a lot of manpower, material resources, funds and time.

The construction of Hong Jizhan is a big project. The cost of building a 5G Hong Jizhan is about 600,000 yuan, while the cost of a 4G Hong Jizhan is only about 6.5438+0.5 million yuan, and the capital cost is four times that of a 4G network. The signal coverage of 5G Hong Jizhan is small, only about 300m, and that of 4G Hong Jizhan is about1200m. Therefore, to achieve the same coverage as the 4G network, the number of buildings in Hong Jizhan is four times that of 4G.

That is to say, in order to cover the signals within the range of 1.200m, a 4G Hong Jizhan needs 1.5 million yuan, but now it needs 2.4 million yuan to build four Hong Jizhan, which is 1.6 times that of a 4G network. According to statistics of relevant departments, the 5G network needs to build 6 million 5G Hong Jizhan and a large number of small base stations.

At present, the tariff of 2.5G is quite high, which is several times that of 4 G.

Things are rare, and 5G is a new thing after all. Just started, the original input cost is high and the starting price is normal; On the other hand, if the starting price is low and the price is raised slowly in the future, no one will want to use it, which is not in line with commercial laws, so the temporary tariff is quite high.

On June 9th this year 10, the three major operators started the 5G reservation activities on their websites. In just a few hours, the number of reserved users reached tens of millions. Subsequently, the official also announced the price of the 5G package, and all of them were discounted, and tactics such as sending phone bills, sending traffic, and sending gifts were used to attract users to book. After the discount, the average price is about 150 yuan, which is tens of yuan cheaper than the current 4 G.

3.5G network needs to be equipped with special 5G equipment to use.

5G network has high frequency and fast network speed. Therefore, if you want to use a 5G network, you need special 5G equipment. At present, most devices in the 4G band cannot receive signals in the 5G high band.

On the other hand, the 5G network has just started, many aspects of technology are immature, and the hardware is also in the research and development stage. In terms of time, it is impossible to put it into use in large quantities at once. In addition, you need to buy hardware equipment, like the current 5G mobile phone, and the cheapest one is nearly 3,000 yuan. Even if you buy a 5G mobile phone, you can't connect the 5G network everywhere, because the temporary coverage area of the 5G network is very small.

4.5G network is mainly used for commercial purposes. If you use it at home, broadband is more dominant.

The 5G network is a high-speed wireless network, and the broadband network at home has been a mature network for decades. It can be said that broadband network is the main network at present, and broadband is standard in all walks of life, work and study, family life, Internet cafes and shopping malls.

Broadband is transmitted through network cable, with small attenuation, high speed and stable signal, which is basically unaffected by any factors. Therefore, it is completely impossible to be replaced by 5G networks for several years, and broadband still needs to be installed.

Fourth, even in the mature stage of 5G, broadband still has many advantages.

The advantages of broadband are not only high speed, small attenuation, stable signal, but also low cost. Moreover, it has a wide coverage in China and a lot of hardware facilities have been built, which is relatively stable. Even when the 5G network is widely used, I think broadband with so much investment and so many advantages may be replaced by the 5G network.

Summary: After the above analysis, broadband will still be installed in the next five years. Even if 5G is widely used, broadband still has many advantages. On the contrary, all aspects of the 5G network are immature, and the construction and development costs are quite high. So broadband network will continue to be used for some time.

Let me answer this professional question for your reference.

With the arrival of 5G, we still need broadband, but not as much as before. Listen to my analysis as follows:

First of all, why don't we need broadband so much now!

Let's talk about the reason why we still need broadband when 5G comes.

5G is coming, do we still need to install broadband? The reliable answer is that broadband is definitely needed.

At present, all three major operators have obtained 5G licenses, and some media tests show that the downlink speed of 5G networks is as high as 1Gbps. In this regard, many people think that there is no need to install broadband at home in the 5G era. In fact, this idea is wrong.

The network speed is not fast after 5G commercialization.

After upgrading 3G and 4G networks, the biggest feeling is that there is a big gap between the speed of media promotion and the speed of actual application.

Take 4G as an example. At first, it was said that the network speed was faster than 100 Mbps broadband. However, after the commercialization of 4G network, the fastest is only about 70M. At present, the 4G network in many areas is only about 30M. Similarly, after the large-scale commercialization of 5G, the network speed will also shrink.

According to past experience, it is good that the network speed of 5G can be stabilized at around 150M after commercialization.

The 5G network fee is more expensive.

As we all know, there is no unlimited traffic package in the current 4G network. The so-called unlimited traffic packages of the three major operators basically start to limit the speed after 20 G.

Similarly, unlimited traffic packages will not be popular in the 5G era because there are too few wireless spectrum resources. There is no unlimited traffic package, and the 5G traffic package is more expensive. Now that the 5G package has not yet come out, even if the traffic per G is only a few cents, the monthly consumption of home Internet access will cost several hundred dollars.

Look at the current home broadband, the monthly traffic is unlimited, and the tariff is only tens of dollars per month.

5G network is not as stable as broadband.

Compared with broadband, 5G network has a fatal disadvantage: instability. Because the frequencies of the 5G network are all high frequency bands, it is doomed that the signal penetration is relatively poor, which is worse than the signal penetration of the 5G frequency band of gigabit wireless routing.

Many home TVs are placed in the living room, and the penetration of 5G signals into the living room will be weakened, and the network speed will also drop. Without good network coverage, it is unrealistic for families to replace broadband with 5G.

In the final analysis, although the 5G network has advantages, it is not realistic to replace home broadband. Regardless of stability, tariffs or Internet speed, 5G is not dominant. What's more, 5G itself is the last mile of wireless access technology, and the cost is definitely higher than the last mile of wired broadband access technology.

Many netizens think that there is no need to install broadband when 5G comes, which is actually a wrong understanding. At least before the full popularization of 5G, ordinary home broadband is still necessary.

First of all, we must clarify the difference between 5G network and home broadband. 5G is a wide area network, and all devices are directly connected to the external network, which means that you can also directly access your home Internet devices from the external network, which increases some risks. Broadband is a local area network, and devices under broadband need to go through a layer of routers to connect with the external network. Many netizens may think that the router is not very important, but it is the first firewall to protect the home network, and many network attacks are actually filtered out by the router. If some smart home devices are directly exposed to the external network without a router, there is a risk of being invaded and monitored by a third party.

And in many cases, the efficiency in the local area network is higher. For example, two computers transmit data to each other, which can be transmitted directly through the router under the local area network, which is fast and safe. However, if it passes through the 5G network, the data needs to bypass the WAN, which is not only inefficient, but also the possibility of data leakage.

Secondly, 5G network is not necessarily faster than home broadband. Although the 5G network promoted by operators can reach 1.5Gbps at the earliest, the speed of ordinary home broadband is usually only 200Mbps. But in fact, the theoretical test speed and actual speed of 5G will be very different. Just like the theoretical network speed of 4G can be 100Mbps, but it is actually only 30Mbps. Therefore, after the official popularization of 5G, it is good for ordinary users to get 500Mbps bandwidth.

In the past two years, the speed of home broadband has been continuously upgraded, and Jiangsu Telecom has begun to promote 1000Mbps( 1Gbps) broadband. Because home broadband is based on optical fiber network, it will not be affected by signal fluctuation and building occlusion. Therefore, compared with the 5G network, the network quality of home broadband is more stable. With the popularization of WiFi 6 standard, the transmission quality of home LAN will be greatly improved, and the transmission speed of intranet will be faster than that of 5G network.

The most important thing is traffic charges. Now is the end of the 4G network, and the three major operators have not yet achieved "unlimited traffic". Even the package with large traffic will slow down when it reaches 40GB. In the early days of the 5G network, although the network speed has become faster, traffic restrictions will still exist, and people will be more careful when using the 5G network to avoid excessive traffic. Moreover, home broadband is generally unlimited traffic, even if it is downloaded at full speed for 24 hours, it will not charge more.

Therefore, I think that in the early days of the 5G network, home broadband is still necessary. Only when the 5G network is fully popularized, the traffic tariff is reduced, and the traffic usage is no longer limited, will the 5G network gradually replace the home broadband. But even so, the home LAN is still necessary and cannot be completely replaced by the 5G network.

Now as long as there is 4G, there is basically no need for WIFI.

What is 5g? Do you really understand?

China has blown 5g into the sky. As far as I know, the download speed can reach 1g, and the fastest can reach 10G.

Now let's look at the text web page, which is tens of K, the web page with pictures may be several m, and a 2-minute video is less than 10m m.

And 4g can meet these needs now.

The arrival of 5g will definitely have a new round of speed-up, but it is certainly not as dreamy as blowing. First of all, your hardware can't keep up with his speed. Our current ssd hard disk has a maximum write speed of about 400 megabytes, and the mobile phone hard disk is the same as the computer hard disk. In other words, his 5g is faster, with a maximum of 400 megabytes, which is the largest.

In order to ensure the stability of the 5g network, many base stations need to be built. The transmission that the base station relies on must be optical fiber, which means that the broadband at home cannot be replaced, so it can be replaced. What about tariffs? People have built such an infrastructure, so it will never be abandoned.

There is the most realistic problem, the speed is fast, can it be used? You can download 34t movies at 400 megabits per second every day. Don't forget that our ssd hard disk 1t costs almost 900, while the mechanical hard disk can't write at 400 megabits per second.

Invited to answer questions in this industry.

5G is coming. For the time being, broadband needs to be developed and installed, but in the later period of 5G coverage, these optical fibers will gradually become the transmission resources of 5G base stations.

In the early stage of 5G, the main product that can replace broadband indoors is 5G CPE, but it can't replace broadband in China.

A typical application of 5G is called wireless home broadband. This service is a home broadband networking service with 5G as wireless access through wired (network cable) or wireless (WIFI) CPE products.

However, it is difficult for this business to develop greatly in China, because of the high fiber coverage in China, and fttp is too common in China now. In the online experience, wired optical fiber access is far superior to the current 5G outdoor coverage indoor mode.

Europe and the United States and other countries prefer this wireless home broadband because of the lack of optical fiber resources. As far as the United States is concerned, the hottest product for operators to promote 5G is also this wireless home broadband.

The three major domestic operators will vigorously promote gigabit home broadband in the early stage of 5G.

At present, the three major domestic operators are all carrying out double gigabit construction. This double gigabit refers to outdoor 5G and indoor fttp Gigabit construction.

In other words, in the next few years, China's wired and wireless networks will further "speed up", with the goal of popularizing Gigabit.

It is basically hopeless to expect 5G Hong Jizhan to cover indoor Gigabit. The working frequency band of 5G is relatively high, the indoor penetration attenuation is relatively large, and the average download speed of 500Mbps can be guaranteed outdoors. The indoor part basically considers some indoor shallow coverage.

After the outdoor 5G coverage is completed, individual homes will be covered by 5G, and operators will deploy 5G through base stations.

The characteristics of 5G are a large number of small base stations, and individual families have family-level small base stations, which mainly belong to pico base stations and flying base stations.

This pico base station can use GPON deployed optical fiber at home. In fact, the gigabit fttp of the current operator has also laid the transmission foundation for the future 5G pico base station at home.

When the price of small base stations drops to a certain extent, it will start to guide small base stations into households, which is a trend in the future of 5G.

At that time, because the power and coverage distance of these pico-base stations are similar to those of current home wireless routers, they can also replace wireless routers.

Moreover, due to the change of network structure, the cost of domestic traffic will be greatly reduced, so that the monthly subscription system can be realized like fttp now, and the tariff can be accepted by users.

All in all, in the early stage of 5G, it was difficult for 5G to replace broadband in the home field, but in the later stage of 5G, small base stations can replace broadband, and now broadband optical fiber will not be wasted.

5G is coming, do we still need to install broadband? I think it is necessary to install broadband, which is more stable than wireless network and has better signal coverage.

Compared with 4G networks, the biggest advantages of 5G networks are large capacity, high speed and low delay. The speed of the 5G network can reach above 1Gbps, and it only takes about 10 second to download a movie with the size of 1G, so the download speed of the 5G network can be comparable to the general broadband network speed.

5G networks all use high-frequency wireless electromagnetic waves. The characteristic of high-frequency electromagnetic wave is that it can transmit more data, that is, the download speed is faster, but its disadvantage is poor penetration and small coverage. Therefore, in order to achieve the expected coverage effect, 5G networks need to build more 5G base stations to enhance signal coverage, which means that operators need to invest more money. However, at present, there are too few mature commercialization of 5G networks, and operators will not actively build networks.

5G wireless home broadband: no fttp, no network cable to enter the home. The receiving equipment of 5G signal is directly installed at home, which converts 5G signal into wifi signal and network signal to solve the access problem of home network. As for the media accessing the home through the Internet, we can look back, from the 56K optical cat, ADSL optical cat and residential broadband connected by telephone lines to fttp now, and there may be 5G access in the future, which deeply feels the development of communication technology.
