Next-Generation Fibre Speeds Will Require Rapid Deployment of Wi-Fi 8

With rising adoption of fibre broadband, in-home networking risks becoming the new bottleneck that slows user speeds, rather than the connection to the home, as it was in the past. That’s why the arrival of Wi-Fi 8 equipment in 2026 is so important: it’ll improve the reliability and robustness of home wireless networks, which will increase the actual speeds that users receive at home. As a result, the gap between the theoretical peak speeds that are promised and the real-world speeds experienced will narrow.

It may seem strange to be discussing Wi-Fi 8 now, when Wi-Fi 7 support is far from common on users’ current devices. It matters now — even when most phones, smart home devices and notebook PCs remain on Wi-Fi 7, 6 or even older Wi-Fi standards — because Wi-Fi access points will benefit from the new standard, even if devices don’t support it. Wi-Fi 8 includes many enhancements to improve the connections between mesh Wi-Fi nodes that are essential for delivering a great experience throughout the home.

Once the new standard is installed, Wi-Fi access points and customer-premises equipment will have a long life. During this period, users will upgrade many of their devices with newer models that support Wi-Fi 8, allowing them to enjoy further improvements in the robustness of their Wi-Fi connection.

Dramatic Fibre Speed Increases Make Wi-Fi 8 Essential

Another important reason to move to the new Wi-Fi standards now is the rapid increase in adoption of fibre to the home (FTTH) and fibre to the building (FTTB), the latter being common in apartment blocks. Subscribers of FTTH or FTTB in the EU and the UK reached 160 million in September 2025, almost double the 83 million of September 2020. The penetration rate has reached 42% of all households.

Fibre is now important even in rural parts of Europe. Rural FTTH and FTTB coverage for the EU and the UK reached 65% in 2025, up from 25% five years earlier, according to the FTTH Council Europe. Overall FTTH and FTTB coverage increased from 42% to 77% in the same five-year period.

Gigabit passive optical networks (GPON) are now being upgraded to the next generation, called XGS-PON. With speeds that are typically ten times faster, XGS-PON can be deployed with existing fibre, and only the active equipment in the central office and customer’s premises needs upgrading.

Some markets have already seen a very large shift to XGS-PON: 100% of fibre networks in Switzerland support it, with 75% in France, 72% in Iceland and 60% in Hungary. It enables speeds of approximately 10 Gbps, more than 10 times the 950 Mbps that’s typical with GPON networks. Once speeds exceed 1 Gbps, even many Ethernet-based wired home networks will struggle to support such high speeds, unless households have upgraded to 2.5 Gbps or higher Ethernet, which is considerably more expensive.

Fibre is important not only because it enables very-fast peak speeds but because the real speeds are much more predictable and less affected by shared capacity — known as contention — or by existing infrastructure. Cable broadband is afflicted by contention, and performance of copper-based DSL technology depends on the length and quality of existing copper cabling. Like those older technologies, Wi-Fi suffers a big gap between advertised and actual performance. However, Wi-Fi 8 aims to resolve that issue.

How Wi-Fi 8 Improves Real-World Performance of Home Networks

With fibre speeds rising, suppliers of customer-premises equipment must combine XGS-PON capabilities with Wi-Fi that’s fast enough to share the fibre connection throughout the home. Fortunately, Wi-Fi 8 devices will launch in 2026. The major Wi-Fi chipset suppliers have all announced Wi-Fi 8 silicon: Broadcom in October 2025, MediaTek at CES 2026 in January and Qualcomm at MWC 2026 in March.

Several new features of Wi-Fi 8 make connections more robust, especially in noisy environments or where more than one Wi-Fi access point creates a single mesh network. These technologies will make the actual speed and performance that users receive closer to the advertised peak performance than with older Wi-Fi versions.

For example, seamless roaming domain (SMD) will make latency, or network responsiveness, better when moving between access points. Some companies have added additional capabilities to further boost performance. For example, ZTE has an in-house AI-positioning engine that uses beamforming to better sense the location of a user device and then adjust the antenna arrays accordingly, in real time. ZTE claims that its solution has a roaming latency of 10 milliseconds and can extend the coverage distance by 50%.

ZTE also uses its smart antenna technology to enhance network quality with Wi-Fi 8’s dynamic sub-band operation (DSO) feature. DSO aims to improve performance when a variety of devices connect with different channel capabilities, such as when one device can support a full 320 MHz Wi-Fi 8 channel, but another can only connect with, say, 80 MHz. ZTE’s DSO solution uses AI scheduling to deliver these benefits, which, the company reports, achieves up to 100% peak-rate improvement to match the speeds of XGS-PON fibre connections to the home.

Another key feature in Wi-Fi 8 that enhances performance for mesh networking is in-device coexistence (IDC). This seeks to improve coordination with other wireless technologies that share the same unlicensed spectrum as Wi-Fi, such as Bluetooth, ultrawideband and Zigbee. This allows the IDC feature to improve the stability and reliability of Wi-Fi in environments where many other devices are also present. This will be important in homes with a high degree of technology and will be especially useful in multidwelling units, such as apartment blocks where wireless signals spill over from nearby homes and can cause increased interference.

Similarly, high-priority enhanced distributed-channel access (HIP EDCA) aims to improve latency to better support time-sensitive applications like gaming and video chat. Again, suppliers often use AI models to differentiate their implementation, such as the one used by ZTE. The company claims that this improves signal stability by 60% and reduces transmission delay of critical packets by 25%.

Combining Fibre and Wi-Fi into Customer-Premises Equipment

Many consumers receive their home broadband routers and Wi-Fi access points from their broadband service provider. This is one reason that Qualcomm uses its business brand, Dragonwing, in its chipsets for home equipment and not its long-standing Snapdragon chipset brand. At MWC 2026, ZTE launched an example of this type of integrated offering with the ZTE Linkpro plus Wi-Fi 8 solution, which combines XGS-PON with Wi-Fi 8.

The rise of fibre broadband is making the move to Wi-Fi 8 more urgent, to avoid Wi-Fi becoming a bottleneck in many homes and to support the increased number of devices being used. Unusually, Wi-Fi 8 has the same peak theoretical speed (23 Gbps), maximum channel size (320 MHz) and best modulation (4096 QAM) as its predecessor, Wi-Fi 7, and supports the same bands (2.4 GHz, 5 GHz and 6 GHz). Its improvements focus on better robustness and reliability, improving the real-world Wi-Fi 8 experience for users. For once, the hype isn’t about peak speed, but real performance that users should notice.
