In a significant advancement for business connectivity, the Wireless Broadband Alliance (WBA) has revealed the results of industrial tests for Wi-Fi 7, conducted in collaboration with tech giants such as AT&T, CommScope (RUCKUS Networks), and Intel. These tests, carried out in real-world scenarios, assessed the performance of Wi-Fi 7 in business environments, highlighting substantial improvements in key areas such as efficiency, performance, and latency.

The main goal of these tests was to analyze how Wi-Fi 7 could optimize cutting-edge business applications, such as extended reality (XR) experiences, artificial intelligence (AI), cloud computing, and industrial Internet of Things (IoT). The results were impressive, showing that Wi-Fi 7 is not only faster but also offers greater stability and handling capacity in dense device environments.

How does Wi-Fi 7 compare to Wi-Fi 6E?

Tests conducted on the 5 GHz and 6 GHz bands clearly showed that Wi-Fi 7 is a significant upgrade compared to its predecessor, Wi-Fi 6E. In particular, Wi-Fi 7 was observed to offer nearly double the performance of Wi-Fi 6E in the 5 GHz band using 40 MHz channels. This speed boost is crucial for businesses that require fast and reliable data transfers, especially those relying on bandwidth-intensive applications such as augmented reality (AR), video conferencing, and automation.

Additionally, in the 6 GHz band, Wi-Fi 7 maintained a sustained performance of over 1 Gbps at distances of up to 40 feet from the access point, with 160 MHz channels. This performance, especially in high-density environments like offices with thousands of connected devices, showcases Wi-Fi 7’s ability to support a large volume of simultaneous connections without sacrificing quality.

Companies that depend on real-time collaboration, video conferencing, and AI-driven automation can now enjoy a smoother user experience without the frustrating delays that impact time-sensitive applications.

Moreover, Wi-Fi 7 introduces a new multi-link (MLO) functionality, allowing multiple connections to be managed simultaneously, optimizing spectrum usage, and ensuring stable connectivity even under heavy load. This is particularly important for high-density networks, such as those found in business environments, where solutions are needed to handle thousands of connected devices at once.

Compatibility with existing networks and easy transition

While Wi-Fi 7 introduces a range of technical advancements, it also ensures compatibility with older networks. This is crucial for businesses that do not want to undergo a complete infrastructure overhaul. Tests confirmed that Wi-Fi 7 offers significant improvements in 5 GHz networks, which are still used by many legacy devices. This facilitates the transition to the new technology without affecting older devices, providing a smoother and less disruptive upgrade for businesses.

What to expect from Wi-Fi 7 in the future?

The results of these Wi-Fi 7 tests open the door to a new era of business connectivity. With capabilities such as higher spectral efficiency, greater network reliability, and exceptional performance even in high-density conditions, Wi-Fi 7 is poised to revolutionize the way businesses deploy their networks. Applications that rely on high data transfer speeds and low latency, such as industrial automation, smart offices, and immersive AR/VR experiences, will be the first to take advantage of these advancements.
