What is Wi-Fi 6? The latest innovation of the wireless network is coming, it indicates that there will be more devices to connect to a faster network in the future. I heard the name "802.11ax" may not make you excited, you may haven't heard of it. For most people, its name will be Wi-Fi 6. No matter if you are familiar with the latest generation of Wi-Fi, it is coming to us.
Previously, Wi-Fi Alliance decided to let us generally understand wireless networks by renaming different standard versions. Now, for the first generation Wi-Fi in 1999, we are no longer called 802.11b, but called "Wi-Fi 1".
Wi-Fi 6, as the name suggests, the Sixth Improvement of Electrical and Electronic Engineers Association (IEEE) to improve its wireless local area network (WLAN) technology, and launch a new standard. IEEE is a professional organization that develops telecommunications industry standards. Briefly, Wi-Fi 6 will make Wi-Fi better; although it is not ready to be widely used, it has appeared in some routers and devices.
Wi-Fi 6 has already aroused your curiosity? Let's take a specific explanation of everything about the next generation of wireless LAN and how it will bring you a better streaming video experience.
Why pay attention to Wi-Fi 6?
Because in theory, Wi-Fi 6 can allow you to avoid interlocking with roommates to watch movies, etc., to avoid network blockage. Bill Menezes, Chief Analyst, Gartner, "Wi-Fi 6 will greatly improve throughput in many devices, with the same wireless access point."
Industry analysts said that Wi-Fi 6 will be around 30% from Wi-Fi 5, and the CNET team found that the former was 40% faster than Wi-Fi 5 or even 1320 megabits per second. This is much faster than most devices run separately, but in the case of connecting multiple receivers on a router, Wi-Fi 6 will greatly speed up the speed.
This improvement will not only affect the 5GHz network (the industry is basically turned to the 5GHz network, which provides faster short-range data); it will also make 2.4GHz network speed faster, although this network is usually slower However, there is a better manifestation in solid objects such as penetrating walls.
What is the magic?
Wi-Fi 6 will transmit data more efficiently to achieve the above speed, which mainly has two main reasons. If you imagine Wi-Fi signals into an access point (such as a router) and a transmission between a device (such as a mobile phone), Wi-Fi 6 will provide more information in one transfer while can also More customers send information.
The first method of achieving this is to send more binary code, then convert it to information using each signal. This can be estimated by QAM (orthogonal amplitude modulation). The current Wi-Fi 5 router is 256-QAM, which means they operate based on the 8-bit binary code of each signal. With Wi-Fi 6, this number will jump to 1024-QAM, the 10-bit binary code. More code means sending more information, that is, data will be transmitted to your device more quickly.
Further, Wi-Fi 6 will be equipped with a technique called orthogonal frequency division multiple access (OFDMA), which can be distributed between different subchannels. Menesses said, "it helps to divide the spectrum, allocate bandwidth, mitigate bandwidth and delay in different users." By creating multiple access points, it allows the router to perform simultaneous with multiple different devices Communication.
What kind of revolutionary place?
LEIF-OLOF Wallin said that Wi-Fi 6 is mainly "evolutionary", but he insists that in some use cases, it may "revolutionize" ". That is, in the case where a large number of users need to connect to the wireless network, such as stadiums, shopping centers, conference centers or airports.
In such a high-density environment, different wireless access points may use the same channel to perform data transmission, which can cause conflicts. Wi-Fi 6 will deploy basic service set (BSS) coloring technology, this technology is shared with digital tags (or coloring), so that the network can intelligently determine whether the channel is too busy. If it is too busy, it is transferred to others. Channel, thereby reducing congestion.
Another useful thing for Wi-Fi 6 is the target wake-up time (TWT), which should increase your device's battery life. TWT will manage your device so that those devices that need to be regularly connected to Wi-Fi (such as Internet access) are only connected according to the planning. This will extend the battery life of the equipment, and can also make your wireless channels any unnecessary conflicts.
Who really needs Wi-Fi 6?
Wi-Fi 6 that can better manage channel congestion environments may meet some more demand.
In a research report in Gartner, Analyst Christian Canales pointed out that in the increasing workspace of networking equipment, such as the employees equipped with four wireless devices - laptops, Tablets, smartphones and wearable devices - buildings are becoming more and more intelligent, and new features from Wi-Fi 6 will be large.
Other areas where improved areas include enhanced reality (AR) and virtual reality (VR), and companies are expected to be able to conduct training, product design or visualization tests. Warlin also pointed out that "fanatic game players and position tracking very important use cases will benefit the greatest."
Of course, this is not to say that Wi-Fi 6 does not change from the life of ordinary consumers. Faster bandwidth will bring improvements, especially in families that need strong Internet of Things. For those who complain about their connection speed, Wi-Fi 6 will be as exciting.
Popularization still needs time
Wi-Fi 6 will definitely come - in fact, it has appeared in the router of NETGEAR or ASUS and other brands and Samsung Galaxy S10. But you may have not benefited from this new technology because Wi-Fi is an ecosystem. This means that you must upgrade all your devices and routers to devices that support Wi-Fi 6 can make full use of their faster speed.
Also, if you are still using the cheapest data package, you should not expect your digital life to have any improvements. If the Internet service you purchased is too slow, even if you use the Wi-Fi 6 router, it will not bring too much change. However, there is no need to start comparison prices, because most network services are not fast enough, so it is impossible to give full play to the potential of Wi-Fi 6.
All of this means that Wi-Fi 6 is also a period of time. Wolin emphasized that it is still in the early days, and the terminal equipment is still still needed. "As usual, there is a slight incompatibility between different suppliers for any new standard." He said.
Menesses predicted that by 2022, only 22% of laptops were integrated with Wi-Fi 6 technology. Therefore, in the past few years, you can save some money on the network service fee.
