Know About Wi-Fi 7, Transfer Speeds and Bandwidth Are Increasing

As of this writing, Wi-Fi 7 is not yet officially launched. But there is a lot of work being done on the specifications. Here's what you need to know.

Wi-Fi 6 was invented some time ago. Today, 6E Wi-Fi devices are coming to the market. And get ready, Wi-Fi 7 is coming soon. This is what to expect from next-generation wireless connectivity and when the first compatible products are launched.

As you might have guessed, Wi-Fi 7 is all about speed boosts. Therefore, hardware capable of supporting it will be able to enjoy higher throughput than before. Technically, we're talking about IEEE 802.11be Extremely High Throughput (EHT) here, with the official Wi-Fi 7 naming, expected to be announced soon.

In the IEEE paper – particularly interesting for a technical discussion of Wi-Fi 7 – the standard is described as promising not only for transfer speeds and bandwidth, but also “for some revolutionary changes to Wi-Fi, which will form the basis for the evolution of Wi-Fi in the future. front." MediaTek promises that the standard will be a realistic replacement for wired Ethernet connections.

What are the advantages of Wi-Fi 7 for the general public?

Until this standard hits devices, some of the specs we'll be talking about are subject to change, but this should give you an idea of ​​where Wi-Fi is headed. If we had to sum it up, we would say that the general public would have access to higher speeds.

Like Wi-Fi 6E, Wi-Fi 7 operates in the 2.4, 5, and 6 GHz frequency bands, supporting up to 30 Gbps. That's a big step up from the 9.6Gbps maximum promised by Wi-Fi 6E, although as usual these are just theoretical numbers, a far cry from what you might get at home.

How does the Wi-Fi 7 trick improve its performance?

Wi-Fi 7 uses a lot of tricks to improve performance. One of them is the use of single channel bandwidth of 320 MHz, compared to 160 MHz in the previous generation. This will increase the speed and throughput for your device. Coupled with the adoption of 6 GHz, it will help reduce the interference between essential devices with all smartphones, tablets, laptops, consoles, smartwatches, smart speakers, etc.

Another important aspect is latency. And again, there will be improvements. Wi-Fi 7 will employ various techniques to ensure that the maximum number of requests is served with minimum delay. One of them is Multi-Link Operation (MLO), which introduces a better way for the product to keep multiple connections open across multiple ranges at the same time.

The technology known as MU-MIMO (Multi-User, Multiple-Input, Multiple-Output) also plays an important role here: the maximum number of streams supported for client devices will increase from 8 to 16, enabling offering more capacity in less time. smaller.

Many of the improvements to Wi-Fi 7 – from Time-Sensitive Networking (TSN) to Quadrature Amplitude Modulation (QAM) to Orthogonal Frequency-Division Multiple Access (OFDMA), for example – require great technical knowledge to understand, but they all contribute to transferring data. faster, to more devices simultaneously and more efficiently.

The goal is to meet the needs of today's Internet users who spend a lot of time watching or streaming videos, making video calls, playing online, immersing themselves in virtual and augmented reality and of course, by connecting dozens of devices on a single wireless router in one corner of their home. .

Coordination between access points will also make it possible to obtain a better network with Wi-Fi 7, so that mesh networks, which have been well democratized in recent years, can manage data and devices more efficiently.

The idea is always to be able to connect more of your devices, at higher speeds, even mobile devices.

What Wi-Fi 7 can't do, of course, is increase the connection speed where you live and until an internet service provider offers something better, this improved Wi-Fi technology won't change your life. Therefore, the first parties to benefit are business and industry.

It will also be a while before we see the first Wi-Fi 7 compatible devices. While the specs have been under consideration for several years, this new generation may not make its official debut before the end of this year and the first consumer products won't be long after. In other words, don't worry, your new Wi-Fi 6 or 6E router still has some free time.

As always, Wi-Fi 7 devices will be backward compatible: they will work perfectly with your old equipment. Because of this, you can update your accommodation little by little, without changing everything at once.
