Wireless Broadband Alliance sees Wi-Fi 7 gains in offices

The Wireless Broadband Alliance has published its Phase 2 enterprise field trials report on Wi-Fi 7 Multi-Link Operation, with findings that point to performance gains for commercial Wi-Fi 7 devices in live office environments.

The trials, conducted with AT&T, RUCKUS Networks and Intel, examined Multi-Link Operation using Enhanced Multi-Link Single Radio with commercial access points and client devices. Testing focused on enterprise conditions, including simultaneous Wi-Fi 7 clients, co-channel interference on the 6 GHz band and mixed traffic loads such as throughput and real-time RTP flows.

The report found uplink throughput improved by as much as 116% under interference, while uplink latency for real-time traffic fell by up to 66%. It also recorded downlink throughput gains of up to 75% under co-channel interference and one-way downlink latency reductions of up to 44%.

In cleaner spectrum conditions, downlink throughput rose by up to 42% and uplink throughput by up to 139%. The largest gains appeared in 40 MHz configurations, which are widely used in enterprise deployments where spectrum contention is common.

Enterprise use

The report places the results in the context of office and campus networks that support cloud applications, video meetings, unified communications, virtual desktop infrastructure, logistics systems, voice services and location-based tools. In these settings, network consistency and response times can matter more than peak speed.

Enhanced Multi-Link Single Radio allows a device to listen on more than one band at the same time and shift traffic to the most suitable band as conditions change. In practice, the client alternates between links but transmits or receives on only one band at a time.

WBA argues this approach can help enterprises manage interference across the 5 GHz and 6 GHz bands without redesigning channel plans or relying on wider channels. It adds that the single-radio approach may reduce cost and power demands compared with more complex client designs.

Tiago Rodrigues, President and Chief Executive Officer of the Wireless Broadband Alliance, said: "Enterprise Wi-Fi has become the foundation for cloud, collaboration and real-time operations, so performance is measured in consistency and responsiveness, not just peak speed. These trials show that MLO is a step change in reliability, helping networks stay stable when conditions get challenging and demand spikes. For IT teams, that means fewer performance cliffs, smoother experiences for latency-sensitive applications and better use of available spectrum. By validating Wi-Fi 7 with commercial equipment in a live enterprise environment, WBA is giving the industry the real-world evidence it needs to accelerate adoption and deliver seamless interoperable Wi-Fi at scale."

Partner views

The work drew support from network operator, infrastructure and semiconductor participants, reflecting a broader industry effort to establish how Wi-Fi 7 performs outside laboratory testing. The use of commercial equipment in live enterprise settings is central to the report's conclusions.

"These results demonstrate the practical enterprise value of Wi-Fi 7 Multi-Link Operation. The trials showed that eMLSR can intelligently use 5 GHz and 6 GHz resources to sustain stronger throughput and lower latency, especially when interference would otherwise undermine performance. What is particularly important is that these benefits were demonstrated with commercial equipment in a live enterprise setting, showing that single-radio MLO can deliver meaningful gains in reliability, efficiency and responsiveness without adding unnecessary complexity," said Cameron Dunn, Co-Chairman of the Wireless Broadband Alliance and Assistant Vice President of In-Building Solutions at AT&T Services.

Intel said the results align with the direction of client device support for the standard. The company took part in the trials and is represented on the alliance's board.

"These trials underscore the step-change Wi-Fi 7 MLO brings to enterprise connectivity. Intelligent switching between 6 GHz and 5 GHz delivers higher speeds, lower latency, and stronger reliability under interference. And with Intel Wi-Fi 7 laptops already supporting MLO, enterprises can realize these gains today," said Necati Canpolat, Sr. Staff at Intel, Project Lead and Wireless Broadband Alliance Board Director.

For network suppliers, the findings are likely to be watched closely by organisations weighing upgrades to office, education, hospitality and industrial wireless systems. Many of these sites face dense device usage, contested spectrum and increasing dependence on real-time applications.

"These trials clearly demonstrate real-life benefits of Wi-Fi 7 and MLO - lower latency, higher reliability and performance improvement under interference. At RUCKUS, we see Wi-Fi 7 and MLO as key enabling technologies to deliver purpose-driven networks that offer superior business outcomes in demanding environments like K-12 schools, university campuses, hotels, manufacturing plants, warehouses, and stadiums," said Saurabh Mathur, Vice President of Product Management at RUCKUS Networks and Wireless Broadband Alliance Board Director.
