Latest white paper reveals 802.11ax will fast track 5G use cases by several years
With nearly 70 percent of smartphone data being carried over Wi-Fi networks, it is clear that cellular deployments in licensed spectrum have not kept pace with consumer demands for wireless data. This has led to the acceptance of Wi-Fi as an important complement to cellular access, and 3GPP’s definition of its 5G core network re-enforces the ability to better integrate Wi-Fi networks as well as its 5G New Radio (NR). While Wi-Fi can complement cellular access and expedite 5G time-to-market, the WBA has released its latest paper to demonstrate how deployment of 802.11ax can lead to early delivery of some 5G use cases by several years and can deliver many of the market requirements as a standalone technology today – all backwardly compatible and can meet the deployment requirements with a strong return on investment and time to market.
The paper identifies the newly introduced features of 802.11ax that address the real business challenges operators and enterprises are looking to solve. These include:
- Multi-User MIMO Uplink & Downlink to increase channel capacity when servicing multiple, simultaneous devices, providing a significant capacity boost for enterprise and carrier networks, large public venues and multi-dwelling buildings.
- Dual Band Frequencies supporting 2.4 GHz and 5GHz to expand spectrum usage possibilities, as well as New Frequency Ranges. This includes the extension of support to the 6GHz band, enabling new swathes of spectrum to be leveraged to deliver improved performance whilst maintaining support to all previous Wi-Fi generations, creating access to wide market
- Flexible Channel Sizes and Resource Units will allow operators to offer more efficient IoT support, such as connections that require lower data rates to use narrow dedicated channels to save power. This also means carriers are able to support both broadband based services as well as IoT over the same network.
- The new Target Wake Time feature allows IoT devices to sleep to reduce access contention and wakeup in scheduled time slots thereby significantly improving device battery life.
In addition to the specific features, the WBA highlights the business advantages of the new standard, from investment effectiveness, speed to market and capacity and density improvements. The paper recognises four key drivers of higher Return on investment (ROI) of Wi-Fi for retailers, manufacturers, service industries, transportation and communities in particular: low cost of deployment; return on investment of unlicensed spectrum; the user value of ubiquitous access; and the free, service-based model of Wi-Fi, over the paid-for access-based model for cellular.
“Investment in 802.11ax offers operators and enterprises a compelling proposition to dramatically accelerate the delivery of 5G use cases, at a much lower cost,” said Tiago Rodrigues, General Manager at the WBA. “However, it shouldn’t be viewed as ‘just the next evolution in Wi-Fi technology’ that can complement cellular. The WBA has developed this paper as part of its venture to raise awareness of 802.11ax as a standalone technology, providing new capabilities which can be used by the entire industry to address a whole new set of opportunities and use cases.”
The WBA and its members invite other industry players to join its Enhanced Wi-Fi 802.11ax work group, which aims to ensure the technology is ready for operator deployment. With plans for early trials of 802.11ax in end-to-end real-life operator networks, work is already underway to examine the key 802.11ax features for deployment scenarios, define the guidelines for the technology, and validate the compelling technical and business benefits of the standard.

“Wi-Fi has rapidly revolutionised nearly every aspect of the last two decades, and the pace of its change on society and economy has been staggering,” said Kishore Raja, vice president of engineering at Boingo Wireless and contributor to the white paper. “As we enter the 5G era, 802.11ax evolves the Wi-Fi standard even further with key features to support a range of next generation use cases, which the WBA reviews at length in this latest white paper.”
“This paper highlights that it is the service-based economic model of 802.11ax which is setting the direction of how 5G will need to evolve as it attempts to target new vertical opportunities,” said Dr. Mark Grayson, Distinguished Engineer at Cisco and Chief Editor of the white paper. “802.11ax isn’t just about better Wi-Fi,” said Dr Mark Grayson, “it’s about a raft of new capabilities that significantly increase the diversity of use cases that can be addressed using Wi-Fi.”
About the Wireless Broadband Alliance
Founded in 2003, the mission of the Wireless Broadband Alliance (WBA) is to resolve business issues and enable collaborative opportunities for service providers, enterprises and cities, enabling them to enhance the customer experience on Wi-Fi and significant adjacent technologies.
Building on our heritage of NGH and carrier Wi-Fi, the WBA will continue to drive and support the adoption of Next Generation Wi-Fi services across the entire public Wi-Fi ecosystem, having a focus on four major programmes: Carrier Wi-Fi Services, Next Generation Wireless & 5G, IoT, and Connected Cities. Today, membership includes major fixed operators such as BT, Comcast and Charter Communication; seven of the top 10 mobile operator groups (by revenue) and leading technology companies such as Cisco, Microsoft, Huawei Technologies, Google and Intel. WBA member operators collectively serve more than 2 billion subscribers and operate more than 30 million hotspots globally.
The WBA Board includes AT&T, Boingo Wireless, BT, Cisco, Comcast, Intel, KT Corporation, Liberty Global, NTT DOCOMO and Orange. For a complete list of current WBA members, please click here: https://www.wballiance.com/join-us/current-members/.
