QCN9274/Super WiFi 7: Explore the unlimited potential of next-generation networks

Wi-Fi provides billions of devices with access to the Internet. According to predictions, by 2024, nearly 4 billion Wi-Fi devices will be shipped every year.

While people are still using versions earlier than Wi-Fi 5, the era of Wi-Fi 7 has quietly arrived.

Wi-Fi has become the most commonly used wireless connection technology for people. From desktop terminals, mobile terminals, home appliances, to cars, Wi-Fi can be seen everywhere. Wi-Fi provides billions of devices with access to the Internet. According to predictions, by 2024, nearly 4 billion Wi-Fi devices will be shipped every year.

With the development of WLAN technology, new applications have appeared in recent years that have higher requirements for throughput and latency, such as 4K and 8K video (the transmission rate may reach 20Gbps), VR/AR, and games (the latency requirement is less than 5ms) , remote office, online video conferencing and cloud computing, etc. Although the newly released Wi-Fi 6 has focused on user experience in high-density scenarios, it still cannot fully meet the needs of the above-mentioned higher requirements for throughput and latency.

Therefore, two or three years ago, Wi-Fi 6 increased the network speed to Gigabit and became the main solution for realizing "double Gigabit" in cities and homes.

It can be said that the capabilities of Wi-Fi are becoming more and more powerful. So, when Wi-Fi 6 has not yet been fully popularized, how powerful is Wi-Fi 7, a "new Internet celebrity"?

A new generation of Wi-Fi standards has emerged

Wi-Fi was born in 1997, and its full name is Wireless Fidelity. With the popularization of network applications, Wi-Fi has brought great convenience to people and has therefore been widely used, making it possible to access the Internet anytime and anywhere. Its impact on human life far exceeds that of most technologies. Some people estimate that the number of devices currently carried by Wi-Fi networks exceeds 20 billion, making it the most important technology for wireless local area networks (WLAN).

Since its birth, Wi-Fi has shouldered the important task of network communication. It has developed for six generations in more than 20 years, which shows its rapid development rate. From 802.11b in 1999 to Wi-Fi 6 in 2019, Wi-Fi speed has increased by a full 650 times in the past 20 years.

With the development of WLAN technology, families and enterprises are increasingly relying on Wi-Fi as the main means of accessing the network. In recent years, new applications have emerged that have higher requirements for throughput and latency, such as 4K and 8K video (the transmission rate may reach 20Gbps), VR/AR, games (latency requirements are less than 5ms), remote office, and online video conferencing. and cloud computing, etc.

Although Wi-Fi 6 has focused on user experience in high-density scenarios, it still cannot fully meet the above-mentioned higher requirements for throughput and latency. A new generation of Wi-Fi is about to emerge, namely the 7th generation Wi-Fi. Standard, seventh generation Wi-Fi wireless network.

Compared with Wi-Fi 6, Wi-Fi 7 will introduce CMU-MIMO technology to support up to 16 data streams, turning 8 lanes into 16 lanes, a proper interstellar highway. Secondly, in addition to the traditional 2.4GHz and The two frequency bands of 5GHz will also be added to support the 6GHz frequency band, and the three frequency bands can work at the same time.

Wi-Fi 7 will bring a new communication technology revolution

In fact, Wi-Fi 6, released in 2019, can already far exceed the speed of 4G when coupled with Gigabit optical broadband. Wi-Fi 7 will provide higher network connection speeds.

So, what are the specific advantages of Wi-Fi 7? To put it simply, the capacity and channels for transmitting data have become larger. If you describe Wi-Fi 7 as a highway, it means that on the Wi-Fi 7 highway, not only can the speed of a car become that of an airplane, but the runway is also as wide as a square.

What’s even more amazing is that Wi-Fi 7 mentioned earlier can support three frequency bands of 2.4 GHz, 5 GHz, and 6 GHz at the same time. Like dining in a crowded restaurant, other people's conversations often encroach on each other's auditory space and people are forced to speak louder. The same goes for Wi-Fi technology.

In dense urban environments, with dozens of devices in homes, neighbors, and people on the street (including buses), access points must drain energy by screaming. Wi-Fi 7 can automatically switch between three frequency bands according to the strength of the signal, and automatically put the signal into the appropriate frequency band. In other words, with a wider channel, different signals can find their own space without consuming too much energy, and the network speed will naturally become faster.

The new features introduced by Wi-Fi 7 will greatly increase data transmission rates and provide lower latency, and these advantages will be more helpful for emerging applications, such as video streaming, voice conferencing, wireless gaming, real-time collaboration cloud, and edge Computing, industrial Internet of Things, immersive AR/VR interaction and telemedicine, etc.

Regarding the future of Wi-Fi 7, quite a few people in the industry are optimistic, believing that Wi-Fi 7, which is "loaded" with many new functions, will bring about a new communication technology revolution.

There are more and more chip solutions and more and more devices are quickly switching to Wi-Fi 7. Wi-Fi 7 is getting closer and closer to reality.
