Understanding Wi-Fi 8 and the Future of Wireless Reliability

The Secret Sauce for Better Connectivity? Better Collaboration.  

There are many tweaks, adjustments, and net new features in Wi-Fi 8 that improve upon the experience of previous Wi-Fi standards. We’ll focus on a few of the most important, but a clear theme emerges in nearly all of them: better collaboration in devices, between devices, and between elements of the infrastructure. A key principle here is that more efficient use of spectrum, better awareness of latency-critical use cases, and coordination between access points all adds up to less interference, less competition, and more seamless connection and roaming.  

• Improved coordination between multiple access points: Previous versions of Wi-Fi have already focused on making better use of RF shaping to adjust for devices struggling on the network. But Wi-Fi 8 introduces new techniques for access points to unify in this effort. One example is Coordinated Beamforming, which takes advantage of beamforming technologies developed in the past and allows multiple access points to beamform in conjunction with each other. This means two access points can functionally steer signal to serve underperforming devices at the periphery of the network, extending an additional line of support to under-served clients.  
• Improved spatial reuse: Wi-Fi 6 introduced the concept of BSS Coloring, which allowed an AP to transmit at the same time as another AP when their coverage was overlapping, given that interference is below a given threshold. The result of this was APs making individual judgments about safe intervals to communicate without destructively impacting neighboring access points. Now, in Wi-Fi 8, these channel scheduling decisions are coordinated by multiple access points, leveraging the other’s available information to extend this concept further and resulting in even better network efficiency.  
• Intelligent sub-channel allocation: Older Wi-Fi devices may only be able to fully utilize 20MHz of bandwidth, which means that reserving any more than that for them on the access point translates to wasted space. New Dynamic Sub-Channel Operation (DSO) allows the network to grant smaller portions of frequency to devices that utilize less, and to reserve more for devices that require more throughput and lower latency. This sharing of the existing channel space further subdivides available spectrum to give every device the allocation it needs without wasting space that could be used for other devices. And this allocation can be adjusted on the fly by the access point if utilization increases or decreases.  
• Better on-client coexistence mechanisms: A very common issue on clients is the need to coordinate multiple wireless systems within a single device. In particular, Bluetooth shares the 2.4 GHz range with Wi-Fi, and device manufacturers must account for the coexistence between these two protocols in order to avoid shouting over one another. Previously this was done solely on-device without assistance from the infrastructure, but now Wi-Fi 8 introduces TXOP-level coordination support from Wi-Fi stations. In this model, stations are able to broadcast when they’re unavailable at the TXOP level and therefore provide information that can help Bluetooth and Wi-Fi devices schedule appropriately. Increased coordination means less guesswork at the device level and more efficient use of available time over air.  
• High-Priority Quality of Service (QOS): Some applications absolutely demand low latency and their packets carry a high priority – think of AR/VR applications, voice calls, or remote robotics control. Their traffic is the utmost priority on a network of devices all competing for access, and dropped traffic on any of these is immediately a problem for the quality of the use case in general. Wi-Fi 8 builds on previous packet prioritization techniques to account for the most extreme outliers in data loss, allowing latency-sensitive devices to receive network priority and to ensure the best possible performance.  
• Better roaming between APs: A predictable point of failure for Wi-Fi devices is when they roam from one access point to the next, or when they drift off of the Wi-Fi network and have to hand off to another connection like LTE. In both of these scenarios, there is a gradual shift of the client’s behavior as it approaches the edge, preparing to make the transition to another network when conditions hit a threshold. Wi-Fi 8 has some solutions for this, and can utilize multiple links to connect to the next access point before dropping the first, as well as new handoff protocols that ensure the transition is smooth with no jitters or drops. Additionally, changes to the modulation and coding scheme table introduce more gradual steps for rates to adjust as signal decreases, leading to a smoother transition to the network’s edge. 

These features of Wi-Fi 8 all enable the same thing: better utilization of the available spectrum and better coordination on both ends of the connection. This generation of Wi-Fi is building towards a profound change: that improving Wi-Fi service is about more than just chasing the highest speeds. It’s about fully utilizing the spectrum and mechanisms available to ensure all devices have the bandwidth they need and receive the priority they deserve. It all adds up to the best possible user experience, which is what users ultimately notice in the end: consistent connections, better service, and uninterrupted experiences powered by Wi-Fi. As a final note the improvements Wi-Fi 8 brings will not provide any advantage in a single AP network, the power of the enhancements arrives when multi-AP mesh and enterprise networks work to provide a higher quality of service.  

The Road Ahead for Wi-Fi 

Wi-Fi 8 has only just recently been announced, and as has often been the case historically it is still in ongoing development. Certification and the first early compatible devices aren’t expected until early 2028, and there is lots of work to be done in the meanwhile.  

For your next generation of Wi-Fi developments, many of the foundational features that are further enhanced in Wi-Fi 8 are already present in Wi-Fi 6 and Wi-Fi 6E devices. This includes features like BSS Coloring, Target Wake Time, the opening of the 6 GHz spectrum, and more designed to dramatically expand available frequency and improve device latency on the network. While Wi-Fi 8 will make significant and meaningful improvements to these mechanisms, in many ways there is untapped potential for Wi-Fi efficiency on the table now in the form of these Wi-Fi 6/6E devices.
