Networking standards are advancing, although most users are not likely to update their equipment as quickly as technology advances.

One example is that although the first Wi-Fi 6 routers were released in 2019, chances are you’re not using one yet.

Although, the industry is already preparing to introduce Wi-Fi 7, the next generation of wireless networking technology.

The next Wi-Fi 7 standard is not a radical departure from previous generations. The new standard will continue to operate in the 2.4, 5 and 6 GHz frequency bands. However, it appears that it will improve the reliability and stability of the connection.

What does WiFi 7 offer?

The IEEE 802.11be standard, which will be known as WiFi 7, is titled Extremely High Yield (EHT)and focuses on gradually improving many of the features added in previous standards, including Wi-Fi 6.

WiFi 6 introduced OFDMA, Orthogonal Frequency Division Multiple Access, which allows routers to handle more connected devices and make more efficient use of available spectrum.

The goal of Wi-Fi 7 is to take these efficiencies one step further with OFDMA coordinated, which allows wireless access points (APs) to communicate with each other and provide better performance on larger networks.

WiFi 7 also claims reduce latency in scenarios such as live video streaming and gaming. Latency is the time it takes for the signal to travel from the router or access point to the device and vice versa.

To do this, Wi-Fi 7 will allow devices to transmit and receive data on multiple frequency bands and channels at the same time. This function, called multilink operation, should help in cases where the network configuration is disrupted by outside interference or even simple congestion of nearby devices.

While improving performance or speed is not Wi-Fi 7’s primary goal, it achieves it thanks to the decision to support wider channels. Channels are sub-bands within the main Wi-Fi frequency bands. The 5GHz band, for example, is divided into 45 smaller channels, with individual channel widths ranging from 20 to 80 MHz.

O new 320 MHz Wi-Fi 7 channels they offer a significant speed advantage over Wi-Fi 6 and its seven 160 MHz channels. While not all devices support these wider channels, they are a welcome upgrade for bandwidth-intensive apps. .

Lastly, Wi-Fi 7 will also increase the number of spatial streams to 16. When combined with support for wider channels, Intel estimates that andThe new standard is expected to offer a theoretical maximum data rate of 46 Gbps. That’s more than a 5-fold increase over Wi-Fi 6’s 9 Gbps.

The increased capacity of Wi-Fi 7, lower latency and improved interference management features make it ideal for new technologies such as AR/VR and streaming games, thanks to reduced latency and greater connection stability.

When will we see WiFi 7 compatible devices?

Wi-Fi 7 is far from being a formal specification at the moment. In fact, the IEEE body has not yet named it Wi-Fi 7. Therefore, consumer devices cannot be expected to support this protocol in the short term.

Work on the protocol is scheduled to end in 2023 or 2024. Even so, it may take another year or two for widespread adoption.

 

Also, although it’s been a year since the Wi-Fi 6E was finalized, Most countries have not yet licensed the new 6GHz spectrum for public use. According to the Wi-Fi Alliance, the US, UK and EU countries have licensed the spectrum, allowing it to be used in internal applications.

Ultimately, Wi-Fi 7 can only get serious when we see greater adoption of current standards. But with the slow launch of Wi-Fi 6E, the next generation could still take several years to find a place in our homes.
