Metaverse and augmented reality, that’s why WiFi 7 will be the pillar of the digital future
The performance of the next generation of connectivity technologies will be at the heart of new application scenarios, including social gaming and edge computing. Analysis by Andrew Davidson, Qualcomm’s Senior Director of Engineering

“The combination of latency, speed and capacity improvements in WiFi 7 will be at the heart of the most advanced use cases in Extended Reality (Xr), Metaverse, social gaming, edge computing and more.” To say it is Andrew Davidson, Senior Director of Engineering of Qualcomm, who with a post published on the company blog has deepened the vision of the group on the role that technology will play in the coming years.

The push of WiFi 6
Davidson points out that WiFi 6 already plays a central role in our lives and economies. “Analysis firm IDC predicts that up to 5.2 billion WiFi 6 devices will be shipped by 2025. Growth like this has many factors, but it’s important to note that WiFi technology has continued to evolve in ways that directly align. to the growing demand. For example, WiFi 6 introduced multi-user functions to improve WiFi performance in densely populated networks, and WiFi 6E expanded these capabilities into the new 6 GHz spectrum band for more broader channels to handle greater speed and lower latency “.
WiFi 7 takes network resources and performance to a new level
Modern high-speed WiFi devices, on the other hand, are increasingly trying to take advantage of the high 5 and 6 GHz bands to deliver the required performance. This reality not only guarantees speed and latency, but frees up the 2.4 GHz band for more suitable applications such as the IoT and devices that operate on the edge of WiFi networks. What perhaps differentiates WiFi 7 from previous technologies is the management and optimization of the various spectrum bands available. “WiFi 7 brings a multitude of features that can be used to deliver extreme speeds, high capacity and low latency to support next generation applications and services,” explains Davidson, noting that WiFi 7’s multi-link capability offers more options. for a client to use the available channels. “The most effective approach is to take advantage of the higher capacity, higher peak speeds and lower congestion of the high bands, allowing devices to switch between them, lowering latency.”
WiFi 7 also doubles the possible bandwidth of the channel to 320 MHz, significantly improving user data rates, and thanks to an innovative solution called “Preamble puncturing”, it can cancel the interfered spectrum while still making the contiguous channel possible. .
Enable new experiences and use cases with WiFi 7
“WiFi 7, in addition to elevating the performance of the applications we use today, will also enable many new experiences,” adds Davidson. “Consider the more advanced Extended Reality (XR) applications, which are extremely latency sensitive to the point that these devices become non-functional unless very low latency metrics are achieved. Immersive and lifelike Xr experiences require exceptionally high video quality with very high refresh rates requiring very high speed and bandwidth. ” Furthermore, the network needs extreme capacity to support a large number of users using these applications simultaneously. Cloud gaming, social gaming and metaverse are further applications that the Qualcomm engineer believes will challenge the boundaries of wireless technology and for which Wi Fi 7 will provide ample performance.
“In corporate networks, intelligence and value are moving to the edge,” concludes Davidson. “The edge-cloud is a key component of corporate digital transformation. The low latency and bandwidth that WiFi 7 can provide, even in dense, high-traffic scenarios, will become vital for many business-critical applications. It goes without saying that WiFi 7 is set to quickly become a prerequisite for supporting high-traffic use cases such as offices, entertainment venues and more. ”
