Everyone expects instant access to the internet, and that’s partly because Wi-Fi standards have advanced so far in the last few years. Wi-Fi 8 is up next, but it’s a little different from its predecessors. No speed bump has been deemed necessary this time around, but what you can expect is increased reliability, seamless hand-offs between different devices and routers, and lower latency. With Wi-Fi woes on the decline, many folks are still making do with Wi-Fi 6, though most homes will have Wi-Fi 6E or Wi-Fi 7 devices in them by now. If you’re in the market to upgrade, all the best routers or mesh systems I recommend now support Wi-Fi 7. You don’t need to consider Wi-Fi 8 for quite a while yet (the standard hasn’t even been finalized), but we can still take a peek at what Wi-Fi 8 has in store to see what's coming. What Is Wi-Fi 8? The eighth generation of Wi-Fi represents a change in focus. While previous incarnations of the Wi-Fi standard have promised higher connection speeds, Wi-Fi 8 seems to be more about improving the basics: reliability, stability, and lower latency. Wi-Fi 8 also promises seamless roaming, keeping devices connected as you move and cutting down on dropped connections and dead zones.

In case you’re wondering, the IEEE is the Institute of Electrical and Electronics Engineers, the folks responsible for these new standards (and yes, they love acronyms). As with all the previous standards, Wi-Fi 8 will be backward compatible, meaning if you buy a Wi-Fi 8 router, it’ll still function just fine with devices on older standards.
But to take advantage of the new features and performance enhancements it promises, you'll also need to upgrade your devices. That means buying new routers and mesh systems, yes, but also new smartphones, laptops, TVs, and other gadgets. What Benefits Does Wi-Fi 8 Bring? There’s a pleasing list of improvements we can expect from Wi-Fi 8, but the headline is Ultra High Reliability (UHR). Wi-Fi 7 was focused on Extremely High Throughput (EHT), but now that speeds are generally great, the focus has shifted to ensuring connections are more reliable. This isn’t a complete list, but here are a few of the features that will enable UHR Multi-Access Point Coordination (MAPC): There’s a bundle of features designed to help access points cooperate instead of interfering with each other. This should improve performance, extend coverage, and reduce power requirements. There’s a bundle of features designed to help access points cooperate instead of interfering with each other.

Seamless Roaming Domain (SRD): Many Wi-Fi drops, which may translate as videos buffering or calls dropping out, are caused by your device switching its connection from one access point to another. SRD is designed to minimize the latency and packet loss that occurs during handoffs.

Low Latency Indication (LLI): This allows devices to share their latency requirements, so a gaming stream (where latency is crucial) can cut in line and take priority. Combined with things like TXOP Preemption and High Priority EDCA, we can expect much better prioritization and more effective Quality of Service (QoS) functionality, so you can ensure the kids streaming Netflix doesn’t interrupt your work video call.
