A very good question. 5G and Wi-Fi 6 are both new generation communication technology standards. They target different application fields and usage scenarios, and there is also a small amount of overlap. Their survival is far greater than competition.
As a key infrastructure that supports society’s “digital, networked, and intelligent” transformation, 5G has attracted much attention. 5G has many new application scenarios, such as edge computing, Internet of Things, autonomous driving, big data, artificial intelligence, telemedicine and other advanced scenarios, all of which require basic support from 5G.
1. High speed
The maximum speed can be up to 100 times that of 4G, and there is room for improvement in this speed.
2. Low latency
A new scenario for 5G applications is driverless driving and industrial automation, and the latency requirement is 1 millisecond or even lower.
3. Large network capacity
Provides connection capabilities for hundreds of billions of devices and covers all kinds of application services.
4. Low power consumption
In order to support large-scale IoT applications, 5G greatly improves user experience by reducing power consumption and promotes the rapid popularization of IoT products.
5. Internet of Everything
In the 5G smart era, not only mobile phones and computers and other Internet devices are connected to the Internet, but more and more different types of devices and public facilities need to be connected to the Internet. 5G Make it possible for these smart devices to be interconnected.
1. New generation technical standard
Wi-Fi 6 is a new generation technical standard with a maximum transmission speed of 9.6Gbps, which has reached the first 873 times that of Wi-Fi.
2. Application scenarios
Wi-Fi is a very successful wireless communication technology. As early as July 1999, Apple began to Wi-Fi was introduced in iBook laptops. After more than 20 years of development, Wi-Fi has changed our lives to a great extent.
Now with the large-scale commercialization of 5G technology, Wi-Fi has to face this new and powerful challenge. At this another crossroads of history, where will it go? Only time will tell.
First of all, WIFI 6 is not just needed by our ordinary users!
The purpose of WIFI 6 is in the smart home area, because its maximum number of connections is more than 200! (This number comes from the public data of Xiaomi’s AX3600)
Therefore, ordinary users cannot use it, because many foreign evaluation agencies have said that it is not as good as WIFI 5 on the existing 80 MHz frequency band. There is not much improvement in speed. The 160 MHz frequency band is not yet open.
Currently, most of the people using WIFI6 are concentrated in large enterprises and users with many smart devices at home, such as Xiaomi Family Bucket users.
The meaning of 5G is different. It can be said that 5G is changing our lives step by step.
Truly fully intelligent autonomous driving, telemedicine, etc.
It is changing our lives, although the current 5G is pseudo 5G and not the real 5G. Because in terms of performance and speed, the current 5G has not yet reached the peak state of 5G.
The speed of 5G makes "loading" a thing of the past, and the low latency makes the Internet of Everything a smart lifestyle that every household will have!
5G allows everyone to experience its convenience and speed, and WIFI 6. For those of you who are transitioning to WIFI 5, you will really feel that the experience after the upgrade is not great. .
After 5G, WIFI6 is ushered in. Which one has the greatest use?
What you see is WIFi6, and the router I use is WIFi6+. Since there is no WIFI6 mobile phone, I have not yet experienced the pleasure brought by speed.
Speaking of 5G and WIFI6, each has its own technical advantages, and each has its best application scenarios. Therefore, the two are interdependent, have long-term existence, and have complementary advantages.
Speaking of uses, it is economical and affordable to choose WIFI6 in indoor environments, and 5G is preferred in outdoor environments, with WIFI6 as a supplement. For special applications, especially those that require high network speed and stability, 5G should be considered first. Therefore, in general, these two technologies should be in an integrated and complementary cooperation mode, and should not be mutually exclusive.
WIFI6 is an important complementary technology for 5G networks and an important supporting technology for indoor scene applications. It will not replace 5G technology!
Both use the same underlying physical technology to improve network speed and capacity. Because there are significant differences between carrier wireless systems and unlicensed wireless systems, such as cost, infrastructure layout, management control levels, etc., the former will not replace the latter. The application of 5G technology will definitely lead to the rapid development of IoT technology. Wireless technology is a necessary technology for connecting IoT devices, so each has its own advantages in terms of use.
With the advent of WIFI6 technology, smart home applications are no longer useless.
WIFI6 is very friendly to the expansion of indoor WIFI communication distance, so it is good for smart home applications. Nowadays, all aspects of people's lives have improved, and smart homes have begun to enter the homes of ordinary people. Among them, most of the complaints are that the application is inconvenient. The fundamental reason is that the communication problem has not been effectively optimized. With WIFI6, this kind of problem can be solved. You only need to set up POD in every house indoors, so mobile devices can be connected to the Internet with a few calls anywhere in the house, and they can communicate with each other.
Conclusion: The uses of 5G and WIF6 are determined based on the actual situation, so no one has a greater use. After all, the work scenarios are different.
Hello, host! Let me write my main points at the front: 5G and WIFI6 both have great uses. There is no "who is the biggest", because comparison without application conditions cannot produce results.
To understand this issue, first let’s understand what technologies 5G and WiFI6 are respectively.
5G technology: The fifth generation of mobile communication technology is the latest generation of cellular mobile communication technology, following 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems. extend. The main advantage of 5G networks is that data transfer rates are much higher than previous cellular networks, up to 10Gbit/s, which is faster than current wired Internet and 100 times faster than previous 4G LTE cellular networks. Another advantage is lower network latency, with faster response times, generally less than 1 millisecond, compared to 30-70 milliseconds for 4G.
WiFi6 technology: The sixth generation WiFi standard, formerly known as 802.11 ax. Wi-Fi 6 mainly uses OFDMA, MU-MIMO and other technologies. MU-MIMO (Multi-User Multiple Input Multiple Output) technology allows the router to communicate with multiple devices at the same time instead of communicating sequentially. MU-MIMO allows the router to communicate with four devices at once, and Wi-Fi 6 will allow communication with up to eight devices. Wi-Fi 6 also utilizes other technologies such as OFDMA (Orthogonal Frequency Division Multiple Access) and transmit beamforming, both of which improve efficiency and network capacity respectively. Wi-Fi 6 has a maximum speed of 9.6Gbps. A new technology in Wi-Fi 6 allows devices to plan communications with routers, reducing the time required to keep the antenna powered to transmit and search for signals, which means reduced battery consumption and improved battery life, ideal for electronics mobile device.
WiFi6 will go hand in hand with 5G
I think "5G replaces Wi-Fi" is to some extent a prejudice without understanding the application scenarios. The application scenario models of 5G and Wi-Fi are different: 5G is a wide area network technology and is more used in outdoor scenarios; Wi-Fi is mainly used in indoor environments, which is why I firmly believe that 5G and Wi-Fi will be the best in the long term. Save it.
Further analysis can be done from the following perspectives:
1. Traffic costs
Let’s assume that one day in the future, 5G will completely replace Wi-Fi. Then on the one hand, operators will It is necessary to launch truly unlimited traffic packages to make up for the network traffic needs of computers, tablets, smart homes and other hardware in home and work scenarios. Otherwise, the cost will far exceed the current broadband cost, and the current broadband of the three major operators is not It's expensive, and they may even give you various gifts such as phone bills, thousand-yuan phones, TV Internet packages, etc. On the other hand, the influx of a large number of devices that existed under Wi-Fi networks in the past into 5G networks will inevitably squeeze network bandwidth and reduce user Internet speeds.
2. Network coverage
A major feature of the 5G network is the use of ultra-high frequency spectrum, which is 24Ghz to 52Ghz. The 4G network frequency band is 1.8Ghz to 2.6Ghz. The higher the frequency, the higher the frequency. The higher the signal, the weaker the ability to cross obstacles, so the 5G signal is easy to weaken to some extent, especially in closed elevators, basements, etc. Although operators can make up for it by deploying a large number of micro base stations, it also means that it is necessary to It costs more; Wi-Fi can be brought into basements and every corner of the building through routers and wired networks, while 5G networks will inevitably leave signal dead spots, making it easier for users to manage networked devices under the same Wi-Fi.
3. Network capacity
Before describing this part, we must first mention a calculation formula: total network capacity = bandwidth x spectrum efficiency x number of terminals. Compared with 4G network, 5G network has higher network speed, larger bandwidth and more stable signal, bringing a better Internet experience. However, as the author mentioned above, the total network capacity is There is a limit. The large bandwidth of 5G does not mean that it can accommodate an unlimited number of receiving devices. Too many access devices will put a very high burden on the base station. At this time, Wi-Fi is needed to offload traffic to reduce the burden on the base station.
4. Faster network speed
The first impression that 5G gives consumers is that it is fast, but in fact Wi-Fi 6 is faster. The single-stream peak rate of Wi-Fi 6 can reach 1.2Gbps, while the peak rate of 5G network is 1Gbps. Therefore, throughout the 5G era, the network speed of Wi-Fi 6 may continue to be slightly higher than that of 5G networks.
5. Terminal types have changed
Since the popularization of Wi-Fi, all walks of life have begun to go wireless, and smartphones, tablets, computers, cars, etc. have all become networked devices. . If 5G replaces Wi-Fi, then all Internet-connected devices in the future must be equipped with a SIM card or eSIM, which will cause great inconvenience to the use of the device, and the price of the device will also rise as a result, making users redundant. purchase and learning costs.
The above is my opinion, I hope it can answer the original poster’s doubts.
5G and Wi-Fi 6 are both the latest versions of their respective technologies. 5G is the next generation of cellular networks after LTE and LTE Advanced. Everyone with a cell phone is known to have cellular networks broadcast from towers, which are designed to cover wide areas.
The promise of 5G may sound familiar, as the new generations all offer similar benefits: faster data speeds, greater capacity and lower latency. But 5G differs from past cellular networks in that it operates in unlicensed spectrum, allowing access to bandwidth not available in previous generations, allowing for faster processing and enhanced connections.
In the age of the Internet of Things, this could be crucial. "It provides the ability to connect not just millions of devices for IoT or massive machine-to-machine communications, but billions of devices," said Chris Pearson, president of advocacy group 5G Americas. Device connectivity. ”
“Any enterprise that wants a very secure, reliable network with many service capabilities end-to-end will choose 5G as their first choice.
”
In the case of 5G, Wi-Fi 6 (or 802.11ax) is the latest standard for wireless network transmission – and like 5G, it promises to be more powerful than previous generations. Faster, broader, and smarter.
But the biggest difference is that Wi-Fi 6 also brings new possibilities for capabilities not available in older wireless standards. Uses Orthogonal Frequency Division Multiple Access. With OFDMA, the access point can be configured to allocate its entire channel to a single user at a specified time, or the channel can be set up to accommodate multiple users simultaneously (for low-bandwidth applications ideal for the program). Result: Improved efficiency, reduced wait time or latency
"What you can do is, you can say I need to remove this much traffic from the network, And I will arrange for these devices to use different slots and avoid each other so that we can better optimize the network. " MacPherson said.
MacPherson said that with the rise of the Internet of Things, this has become a necessity. High-density environments used to be limited to stadiums and concert halls, but as enterprises use more and more devices, plus personal devices like smartwatches, the enterprise has become a high-density environment
While the adoption of 5G and Wi-Fi 6 is still in its early stages, But both have huge potential for businesses. All sectors can benefit from faster data speeds and less latency, but industries that rely more on connected devices and mobility will gain from these new technologies. Maximum benefits.
“If you are a smart grid and want to better monitor the grid and better understand how to manage power, having 5G IoT sensors, devices and capabilities will be an opportunity,” said Pearson .
For Wi-Fi 6, MacPherson said OFDMA scheduling can optimize battery usage of devices, which will be particularly useful for the industry, he said: "We are already seeing improvements in these early deployments, but As software becomes more complex and scheduling algorithms become more complex, we will see these increases. "
"Maybe there are limitations on the factory floor because you can't run fiber optics to every robot and you can't connect fiber optics to certain endpoints to enable intelligent automation," Pearson said. "When you When you see what 5G can do, you start to think about spending a little more money to do it. ”
The same advantages that can help businesses become more efficient will also help their workers get their jobs done. As more employees seek to achieve this with the support of remote work and mobility Work/life balance, strong connections with collaborative technology are imperative Remote working is enabled by technologies such as video conferencing and digital telephony, and these need to be synchronized correctly to be effective, says McPherson. You don't want someone talking on the screen and then hearing the voice sound like it's from those old Japanese movies. You want it to be synchronized, and you want it to be real-time. "
While the benefits can be huge, as with adopting new technology, there will be adjustments. "We are entering a time where people can come up with new ideas, new business plans and new ways of doing business," predicted Pearson. era. I think it's positive for workers, but they also have to develop. "
MacPherson said that while some may prefer 5G or Wi-Fi 6 as the best way forward, it is actually a joint effort of the team. "Some enthusiasts believe that Wi-Fi 6 solves all problems, and some believe 5G solves them all. But the answer lies in the middle. "
"We support a bright future with 5G," said Pearson of his organization, 5G Americas. "But we also think Wi-Fi 6 plays a very healthy role. "
For a company like Cisco, MacPherson said the goal is a seamless network experience. "It's not just doing good technology, but the ability to connect technologies together," he said.
We want to provide you with the best connectivity experience and ensure your experience is seamless. ”
In the past year, two new standards have been released and constructed, one is 5g and the other is WIFI 6. These are technical standards for two different application scenarios. 5g It is mainly for outdoor use, while WIFI 6 is mainly for small area places such as home venues.
5g means the fifth generation of mobile communications. It is in parallel relationship with the 4G technology we are now commonly using, mainly. Mobile phones implement mobile voice communications and data services through the operator's base station.
WIFI 6 is the sixth generation of WIFI technology. In fact, a more accurate description should be the WIFI version that has developed to the sixth generation. . Its standard is 802.11 ax, but it was changed to the more popular name of WIFI 6 by the WIFI Alliance. Now we mainly use 802.11n, which is WIFI 4, and 802.11 AC, which is WIFI 5.
5g, like WIFI 6, has higher speeds, larger capacity, and lower latency. Of course, just having a 5g base station and WIFI 6 router is useless! You also need a mobile phone, a flat-screen TV, etc. Only when terminals meet the same standards can they enjoy these better technologies. As a new technology, new standards will become mainstream in the future!
1. 5G is mainly a mobile communication technology< /p>
In fact, 5G is mainly mobile communication technology, that is, cellular communication technology. Although it seems to have many similarities with WIFI 6, the most important thing in 5G is voice calls.
< p> At the same time, based on the 5G network, in addition to voice calls, it also supports edge computing, Internet of Things, autonomous driving, big data, artificial intelligence, telemedicine and other technologies.
Other technologies. The main reason is that the coverage is farther and the coverage is wider. At the same time, operators have unified coverage across the country.
2. WIFI 6 is mainly a wireless data transmission technology.
WIFI technology is mainly a wireless data transmission technology. Wireless data transmission technology is not used for voice calls, as everyone knows. It is mainly that each device is connected to the network through wireless technology, such as computers, smart homes, etc., through a WIFI technology. A relatively small local area network, and then each device is connected to it for data transmission.
It can be seen that these two technologies have certain similarities, but they have some differences. Different applicable scenarios, there is no saying which one is more useful. After all, the two technologies have different functions and cannot be directly compared.
5G and WiFi 6 are two major network technologies that go hand in hand, and no one is more useful. First of all, the two are just different application scenarios, one is mainly indoors and the other is mainly outdoor. For us ordinary people, the two are complementary.
Generally speaking, 5G and WiFi 6 coexist. Rather than a competitive relationship, they are all the latest technologies in their respective fields and will contribute to the benefit of mankind.
Be invited to answer industry questions.
5G and WiFi are in a competitive and cooperative relationship. In the early stage, there was mostly cooperation, but in the later stage, there was mainly competition. The overlapping area of ??5G and WiFi is mainly indoor application scenarios, including some home-level applications and enterprise-level applications. Judging from the application scenarios of the two, the use of 5G is greater than that of WiFi applications.
WiFi technology is a wireless LAN technology and an extension of the fixed network. WiFi technology emerged because some devices need to exchange data through wireless technology.
WiFi technology started with IEEE 802.11b in 1999 and continued to IEEE 802.11ax in 2019. In between, there are also IEEE 802.11a in 1999, IEEE 802.11g in 2003, and IEEE 802.11n in 2009. In 2013, IEEE802.11ac went through 6 major versions.
In 2019, the WiFi Alliance renamed WiFi and defined them as WiFi 1 to WiFi 6 in order of appearance. Now the WiFi 6 we often mention is IEEE 802.11ax.
The advent of WiFi 6 is relatively similar to that of 5G, and it is also considered to be a technology of the same period as 5G.
5G can achieve a theoretical maximum access speed of 9.6Gbps, which is relatively close to the speed of 5G.
WiFi 6 has not changed from previous WiFi application scenarios. WiFi 6 technology based on unlicensed frequencies is mainly used in indoor places, such as inside homes and some offices. In areas, transportation hubs such as stadiums, train stations, and airports, and commercial scenes such as shopping malls, a small number of industrial IoT devices use WiFi as the access technology.
Compared with the previous generation of WiFi technology, the main performance improvement of WiFi 6 is more towards the support of Internet of Things devices, with high speed, low latency and large bandwidth. Connection is the technical feature of WiFi 6, which is relatively similar to the three major application scenarios of 5G.
WiFi technology is a local area network technology and its application range is within 1 km. Compared with WiFi technology, 5G is a wide area network technology that supports large-scale movement of terminals and global roaming, which WiFi technology cannot achieve.
In addition, since WiFi cannot ensure the security of the device, some devices with relatively high security requirements will not use WiFi to connect, such as some public facilities and industrial IoT equipment. wait.
In the development process of 5G, it is difficult for 5G base stations to achieve comprehensive coverage in the early stage. Operators’ 5G construction mainly focuses on outdoor coverage, with some indoor shallow coverage taken into account. This is indoor area, it needs to be supplemented by WiFi 6.
Along with 5G, there will also be an increase in the speed of fiber-to-the-home broadband, and the promotion of 1000M-level broadband will also be the speed increase of fixed networks that operators will carry out in the 5G era.
Gigabit broadband is obviously not enough with WiFi 5. WiFi 5 with the current terminal configuration can basically only support a transmission rate of 867Mbps, so it also needs to support WiFi 6 with a higher transmission rate.
And with the increase of smart home devices in the home, the access terminal restrictions of traditional WiFi 5 routers have also restricted the development of smart homes. In this area, the support of WiFi 6 is also needed.
At present, China's three major operators also have requirements for supporting WiFi 6 for 5G mobile phones, which also illustrates the necessity of WiFi 6 in the early stage of 5G.
As operators’ 5G outdoor coverage improves, eventually operators will begin to shift to indoor partial 5G coverage. Here, 5G small base stations are mainly used for coverage. Small base stations based on 5G will be able to provide home-level and indoor-level coverage, and due to changes in the network structure in the later stages of 5G and the introduction of edge computing, home-level 5G access will be available on a monthly basis like the current fiber-to-the-home system. , at this stage, 5G will directly compete with WiFi 6 in home scenarios.
To achieve this, the price of small base stations is the biggest problem. The current price of 5G pRRU is still at the level of 10,000 yuan, which is difficult to popularize. .
All in all, WiFi 6 is a wireless LAN technology that mainly covers indoors, while 5G is a wide area network technology that can cover both indoors and outdoors. In terms of application scenarios, 5G is wider than WiFi 6 of. In the early stages of 5G, the application scenarios of WiFi 6 will partially overlap with 5G. However, in terms of home scenarios and some special indoor scenarios, WiFi 6 will be an important supplement to 5G. In the later stages of 5G, who will ultimately gain the upper hand between 5G and WiFi 6 depends on how the industry chain develops and how operators make decisions. In terms of technology, 5G can replace WiFi 6, but WiFi 6 cannot replace 5G. of.
I am Lechuang IoT! Let me answer this question. I mainly work on the Internet of Things and industrial automation.
Different application scenarios of 5G and WiFi6 will have different developments. It is a bit premature to say which one has the greatest use. Let’s take a look at 5G and WiFi6 respectively.
1 What is 5G?
The fifth generation of mobile communication technology, referred to as 5G. It is the latest generation of cellular mobile communication technology and a new extension after 4G (LTE-A, WiMax), 3G (UMTS, LTE) and 2G (GSM) systems.
5G
2 5G network characteristics
High speed, based on Gbit/s as the standard, can meet the transmission of large amounts of data such as high-definition video and virtual reality; Low latency, about 1ms, can meet real-time applications such as autonomous driving and telemedicine; Ultra-large bandwidth can provide connection capabilities for hundreds of billions of devices to meet various Internet of Things communication applications; Spectral efficiency is more than 10 times higher than that of 4G, etc. . The above four points are the differences between 5G and previous generations of mobile communications, and are also the result of the gradual transformation of mobile communications from technology-centered to user-centered.
3 What is WiFi6?
WiFi 6 is actually the 6th generation wireless technology - 802.11 ax. The biggest significance brought by WiFi6 is lower latency and more stable connection.
Comparison of WiFi generations
4 latest applications of WiFi6
Lei Jun focused on WiFi6 in Xiaomi 10 (Xiaomi’s ten-year dream); Hisense in 2020 At the spring new product launch conference, Xiaomi launched the first TV equipped with WiFi 6 in China; on April 17, Xiaomi’s first WiFi6 router went on sale.
Lei Jun introduces WiFi6
5 5G and WiFi6
WiFi 6 is a wireless LAN technology that mainly covers indoors, while 5G is a wide area network technology that can cover indoors and outdoors. In terms of application scenarios, 5G is broader than WiFi 6. In the early stages of 5G, the application scenarios of WiFi6 will overlap with those of 5G, but in smart home scenarios and some special indoor scenarios, WiFi6 will be an important supplement to 5G. However, in the later stages of 5G, whether it is 5G or WiFi 6, it will depend on the development of the industry chain and the choice of operators, which will determine who has greater development use.
