The speed at which we browse the Internet is about to change. arrival from WiFi 7 to the market will be a significant jump in quality in streaming and online games. So understand what it is, how it works and what are the benefits of WiFi 7 is the first step in preparation.

You first routers compatible with WiFi 7 were announced in late 2022, but none have yet gone on sale. 2023 is still expected to be a year of technology development, so that in 2024 it will be able to reach its full potential.

Will WiFi 7 revolutionize the way we use the Internet?

What is WiFi 7?

WiFi 7 is a trademark IEEE 802.11b and Extremely High Throughput (EHT). This standard focuses on making full use of the spectrum resources of the three bands – 2.4 GHz, 5 GHz and 6 GHz. greater speed and efficiency.

To give you an idea, while WiFi 5 reaches a transfer rate of 6.9 Gbps, WiFi 6 operates at 9.6 Gbps. already WiFi 7 can reach an impressive 46Gbps. The idea is to reduce buffering scenarios, response time delays, or network traffic congestion.

How does WiFi 7 work?

How is it possible that WiFi 7 offers more bandwidth and double the speed? Much due to better use of the 6 GHz band. Allowing a channel width of up to 320 MHz, WiFi 7 supports more simultaneous connectionsat higher speeds without sacrificing stability.

This is not only an increase in the number of antennas, but also an increase in the number of spatial streams: from 8 to 16. This characteristic will be extremely useful in scenarios with several devices connected to the network, such as in environments with connected home resources.

The modulation format adopted in WiFi 7 is also better. 4096-QAM (or 4K-QAM) allows each symbol to carry 12 bits instead of 10 bits, resulting in Up to 20% faster transmission speed than the 1024-QAM standard used in WiFi 6..

Finally, in WiFi 6, the user can only send and receive data in the assigned resource unit (RU). In WiFi 7, multiple RUs can be assigned to a single user, which improves transmission efficiency.

What are the benefits of WiFi 7?

There are several benefits of WiFi 7 over previous generations. This seventh generation promises the smoothest and most dynamic online experience we’ve ever seen. Benefits can be seen in almost every area, from audio and video streaming to online gaming.

1. Transfer rate up to 46Gbps

Without a doubt, this is one of the main advantages of WiFi 7: high transmission speeds. The nominal limit is 46 Gbps, which is 4.8 times more than WiFi 6.

2. Latency up to 100 times lower

Latency reduction would be another big benefit. Even in the worst case, the gain can be up to a hundred times better than WiFi 6. This will be extremely useful for the development of the use of applications in augmented reality and virtual reality, in addition to streaming in 8K. Responsiveness will be the same as that of a wired network.

3. Large network bandwidth

While WiFi 5, WiFi 6, and WiFi 6E operate on 20, 40, 80, and 160 MHz channels, WiFi 7 will be able to operate at frequencies up to 320 MHz with multi-channel operation (MLO). This means an increase in network bandwidth up to 5 times compared to the previous generation.

WiFi 7 x WiFi 6E x WiFi 6 x WiFi 5: version comparison

In the table below, you can see the differences between the specifications of each WiFi version. WiFi 5, released in 2013, was a significant step forward in the world of connectivity.

On the other hand, WiFi 7 will be able to go further by offering faster transfer speeds, more network bandwidth and lower latency, all without leaving aside compatibility with previous generations. In other words, your new WiFi 7 router will support all connections that current models support.

When will WiFi 7 be available?

The WiFi 7 launch window is expected to occur sometime between 2023 and 2024. Therefore, although there is no official date, the first routers compatible with this technology are expected to hit the market by the end of next year.

At the end of 2022, TP-Link announced its first line of WiFi 7 routers with three models: Archer BE900 supporting up to 24Gbps; Archer GE800, gamer model; and Deco BE95, a Mesh version that supports up to 33Gbps.

ASUS also announced the WiFi 7 model during CES 2023, which is the ROG Rapture GT-BE98 with support for transfer rates up to 25Gbps. None of the templates are available yet.

Qualcomm has already confirmed that the Snapdragon 8 Gen 2 is compatible with WiFi 7, but with support for data rates up to 20Gbps. Intel and MediaTek also promised news on the subject in 2023.

Their supported throughput ratings are still nearly 50% below the technology’s maximum potential, but still significantly higher than current models reaching 10Gbps.
