Similar to Wi-Fi 6E with the ability to use 3 bands, but the speed of Wi-Fi 7 will be twice as fast. Will this put the name Wi-Fi 6 into the past?
Wireless networking, also known as Wi-Fi, is already very familiar with today’s 4.0 life. But now there are quite a few different standards for this type of network, namely Wi-Fi 5, Wi-Fi 6, Wi-Fi 6E and soon Wi-Fi 7 (known as 802.11 by ‘industry’ people) beige).
Without going too deep into the technical details, the article will give an overview of Wi-Fi 7 and its improvements over its predecessor standards, and explain some of the reasons why people use it. Users should not rely too much on this new Wi-Fi standard.
How is Wi-Fi 7 different from Wi-Fi 6 (and 6E)?
For many people, Wi-Fi 6 is still quite new. Maybe you don’t even own a Wi-Fi 6 router.
And of course, what you can expect from a Wi-Fi upgrade: Better reliability, faster speeds, and wider range. In theory, Wi-Fi 7 should provide all three of these aspects.
Wi-Fi 7 with many outstanding features will give twice the speed of Wi-Fi 6E.
Wi-Fi 7 will still use the 2.4GHz, 5GHz, and 6GHz bands. It can work faster and in theory, better coverage by taking advantage of the ability to use the aforementioned 3 bands at the same time.
Compared to Wi-Fi 6E, Wi-Fi 7 will have 3 main advantages, including:
– Channel widths up to 320MHz (Wi-Fi 6E is limited to 160MHz). So a Wi-Fi 7 router that can provide 4 streams at the same time has a maximum speed of 9.6Gbps.
Multi-link operation allows the 5GHz and 6GHz bands to be used together to act as a single connection. This will give very fast speeds, but a device that supports this feature is required.
– Wi-Fi 7 supports very high QAM (4K-QAM). With QAM is the method of sending more data per 1Hz frequency. Wi-Fi 5 supports 256-QAM and Wi-Fi 6 is 1024-QAM. Wi-Fi 7 quadruples this to 4096-QAM, which is why it’s called 4K-QAM.
The companies that make Wi-Fi 7 chips promise that the new standard will replace wired Ethernet cables. But this information seems to be exaggerated. Basically, Wi-Fi works differently than wired networks.
With a Wi-Fi connection, data can only be sent in one direction at a time, while data can be sent in both directions simultaneously when traveling over an Ethernet cable. The most recognizable comparison here is a walkie-talkie and a telephone. With walkie-talkies, you have to talk, wait, and listen for a response. But during a phone call, you can talk to the other person at the same time.
So while Wi-Fi 7 uses some clever technology to work faster, it will never replace network cables.
When will Wi-Fi 7 be available?
Although Wi-Fi 7 is still under development, there have been reports of Qualcomm and MediaTek announcing chips that support this connection standard.
In May 2022, Qualcomm announced four chip lines 1620, 1220, 820 and 620, which can be used in home routers as well as Mesh systems. Later that month, MediaTek also announced the Filogic 880 with a top speed of 36Gbps, a chip with dual Wi-Fi 7 and Bluetooth 5.3 waves for phones, laptops, TVs and set-top boxes.
It is still unclear when the above manufacturers will announce products using Wi-Fi 7 chips. But there are many predictions that the first Wi-Fi 7 routers will go on sale in 2023, but will not provide a “huge” 9.6Gbps speed.
The standard may not even be certified until 2024, leaving implementation behind a fog. It will probably be a while before we see a phone, laptop, or tablet using Wi-Fi 7.
Should you expect Wi-Fi 7?
The answer at the moment is no, if you have ever looked at the price of the Wi-Fi 6E router and its Mesh system. Surely the first Wi-Fi 7 device will be very expensive.
It’s also possible that the price issue will fade, but betting to buy a device before Wi-Fi 7 is certified is extremely risky. Because your devices may not be compatible with the latest standard.
If you are looking for a new router, consider keeping your existing Wi-Fi router compatible and investing in a Wi-Fi Mesh system to provide good coverage. than. In addition, even a good 5 Mesh Wi-Fi system will still provide excellent speed and coverage without having to cost too much.
Mesh technology is increasingly being applied widely to remove “dead spots” of Wi-Fi in large, relatively thick homes.
