Wi-Fi 7, what it is and how the near-zero latency standard works

I received router compatible with the Wi-Fi 7 they have already seen the light in 2023 but, obviously, many new products are planned for 2024 ready to use this new standard in all respects.

Furthermore, one of the main problems encountered by users is that there aren’t many devices yet on the market capable of supporting this new technology but the arrival of the new routers will also correspond to a greater diffusion of the various ones smartphone, tablet e PC compatible with the new standard with many companies also considering a “retroactive certification” for products already on the market.

Now with the official presentation which took place at CES 2024 in Las VegasWi-Fi 7 is ready for mass diffusion and we will certainly hear a lot more about it in the next few weeks, especially about the next hi-tech products coming out.

The development stages of Wi-Fi 7

As is well known, the “old” Wi-Fi 5 uses two frequencies: 2.4 GHz and 5 GHz. The first passes through walls better and has a more extensive coverage while the second manages to send more data per second.

The direct evolution of this standard is, clearly, the 6 GHz frequency with the first devices compatible with the Wi-Fi 6 which in recent years have become increasingly common, especially in the category of top of the range.

Furthermore, the 6 GHz frequency is also used by some mobile telephone operators for data transmissions, such as those used for 5G.

One of the key functions of the Wi-Fi 6 it is the so-called “Uplink Multiple User Multiple-Input Multiple-Output” (UL MU-MIMO). Behind this complicated name is the evolution of technology, which already exists and works on routers Wi-Fi 4 by 5, Multiple-Input Multiple-Output (MIMO).

We are talking about a system that sends data packets along multiple paths via different antennas to maximize the transmission speed

Wi-Fi 6 initially used the Multiuser MIMO (MU-MIMO), i.e. sending a signal to multiple users at the same time, always using the MIMO technology.

Direct evolution is l’Uplink MU-MIMOwhich especially improves the uplink, i.e. the “uplink” connection, for upload performance higher.

The technologies that will bring users into the Wi-Fi 7 standard will arrive during 2024. Among these the CMU-MIMOwhich can be imagined as a “Collaborative” MU-MIMO: with different routers they communicate with each other and collaborate to transmit data together following the MIMO standard.

If up to 8 antennas can work together in MIMO with Wi-Fi 6, with Wi-Fi 7 they will be able to collaborate up to 16 antennasimproving the coverage and the transmission speed exploiting the transmission power of the antennas of multiple routers and access points simultaneously.

Where are we at with Wi-Fi 7?

Durante il CES 2024 il Wi-Fi 7 was presented by Wi-Fi Alliance which illustrated to the Las Vegas public all the new features regarding the features arriving with the diffusion of the new standard.

According to initial estimates, it seems that in 2024 they will be more than 233 million devices capable of adopting Wi-Fi 7.

A number destined to grow and which, by 2028it will touch i 2.1 billion products between smartphones, PCs, tablets, AR/VR viewers and much more.

A big step forward for users and their devices that they can count on connections (Still) more reliable come on higher speedsready to perform all modern uses ranging from “simple” entertainment on the web (between streaming platforms and consoles) and up to new technologies for productivity strawberry la smart homeincreasingly dominant within our homes.

What changes with the arrival of Wi-Fi 7

Naturally there will be many advantages of the advent of Wi-Fi 7 compared to previous generation protocols.

First of all, support will be guaranteed for one higher channel bandwidth (from 160 MHz to 320 MHz) capable of bringing a download speed really important (around 2 GB/s in wireless mode).

Simply put, this means that you will have a connection four times faster than the current Wi-Fi 6 standard.

Moreover, it will be possible pair two wireless bands combining them as if to create a single Wi-Fi network. This discussion refers to what has already been said in the previous paragraph and, by exploiting MLO (Multi-Link Operation) technology, it will be possible to further increase the bandwidth and, naturally, improve the signal stabilityfor significantly more connections reliable and much more efficient.

An MLO system also offers many advantages in terms of latencywith all due respect to gamers who will be able to count on one much more responsive connection. Furthermore, with the transition to Wi-Fi 7 there will also be less interference on the network

Naturally, as always happens with the advent of new technologies, older devices will not be able to directly use the new standards and will not benefit from the benefits just described

This technology is obviously backwards compatible but to make the most of its potential it will be necessary purchase one of the new devices arriving on the market in the next few months.
