Wi-Fi 7 vs Wi-Fi 6
The Next Generation of Wireless Connectivity: Wi-Fi 7 vs Wi-Fi 6
Wi-Fi 7 is newer than Wi-Fi 6, but that doesn’t mean every home needs it. The difference you’ll notice depends on the router and devices you use, your broadband speed and which Wi-Fi 7 features they support. Wi-Fi 6 is still enough for many households. Wi-Fi 7 is more useful if you have compatible devices, a busy network or a multi-gigabit connection.
Understanding Wi-Fi 6 (802.11ax)
Launched in 2019, Wi-Fi 6 brought a focus on network efficiency, particularly in environments with many connected devices. It introduced technologies like Orthogonal Frequency-Division Multiple Access (OFDMA) and Multi-User, Multiple-Input, Multiple-Output (MU-MIMO) to allow multiple devices to communicate simultaneously without slowing down the network. Wi-Fi 6 supports theoretical maximum speeds of up to 9.6 Gbps.
The Major Leap Forward: Key Features of Wi-Fi 7 (802.11be)
Here’s how Wi-Fi 7 differs from Wi-Fi 6:
- Extreme Speed: The often-quoted 46Gbps figure is a theoretical maximum for a high-spec configuration, not a typical router speed or the broadband speed you’ll get at your address. High-bandwidth activities such as 4K/8K video streaming, augmented and virtual reality, and cloud gaming can benefit from additional wireless capacity when compatible devices and the broadband connection can use it.
- Wider Channels: Compatible Wi-Fi 7 equipment can use channels up to 320MHz on 6GHz, but not every Wi-Fi 7 router or device supports 6GHz or 320MHz.
- Multi-Link Operation (MLO): Multi-Link Operation can let compatible Wi-Fi 7 devices use more than one supported link. How those links are used depends on the router and client device.
- Higher Data Density (4K QAM): 4096-QAM can carry more data per transmission than 1024-QAM when the signal is strong and both devices support it. It doesn’t guarantee a 20% increase in everyday internet speed.
Comparison Table: Wi-Fi 6 vs Wi-Fi 7
| Feature | Wi-Fi 6 (802.11ax) | Wi-Fi 7 (802.11be) |
|---|---|---|
| Max Theoretical Speed | 9.6 Gbps | Up to 46Gbps in a theoretical high-spec configuration; not a household speed |
| Channel Width | 160 MHz | Up to 320MHz on compatible 6GHz equipment |
| Modulation | 1024-QAM | 4096-QAM |
| Key Features | OFDMA, MU-MIMO | MLO and other features, depending on device support |
| Primary Focus | Network efficiency | Higher capacity on compatible equipment |
WiFi 7 vs WiFi 6: Is it Worth It?
You've probably seen WiFi 7 around more and more but is it worth the upgrade from WiFi 6 or 6E? Here's a video describing the real differences so you can decide.
What Does This Mean for You?
For the average household, Wi-Fi 7 offers a significant improvement in performance, especially in busy homes with numerous connected devices. The technology is designed to handle simultaneous high-bandwidth activities such as a family streaming movies in 4K, a teenager gaming online with low latency, and a remote worker on a video call – although actual performance depends on the router, devices and broadband connection.
While Wi-Fi 6 is a solid choice for most people today, if you are looking to future-proof your home network, support the latest multi-gigabit broadband packages, and ensure a smooth experience for the next generation of smart home devices, Wi-Fi 7 may suit you if your devices support it and you’re choosing a multi-gigabit package.

Wi-Fi 7 Frequently Asked Questions
Is Wi-Fi 7 backwards compatible?
Yes, Wi-Fi 7 routers are designed to be fully backwards compatible with all previous Wi-Fi standards, including Wi-Fi 6, 5, 4, etc.
Do I need a new router and new devices for Wi-Fi 7?
To get the full benefits of Wi-Fi 7, you need a Wi-Fi 7 compatible router and devices that support the standard. Your existing devices will still connect, but at their older standard's speed.
Is Wi-Fi 7 available yet?
Yes, Wi-Fi 7 is available. The Wi-Fi Alliance, which certifies Wi-Fi products, launched its certification programme in early 2024. Many companies are already releasing routers and devices that support the new standard.
Is Wi-Fi 7 available in the UK?
