Any links to online stores should be assumed to be affiliates. The company or PR agency provides all or most review samples. They have no control over my content, and I provide my honest opinion.

MediaTek is the last of the three big vendors to announce its range of WiFi 7 chips. Qualcomm announced its WiFi 7 Networking Pro series at the start of May, and Broadcomm has four WiFi 7 products within its ecosystem which were announced back in April.

While the development of WiFI 7 is ongoing and the final version isn’t expected until 2024, I’d expect we may start to see some consumer hardware in 2023. It is quite possible that the next generation of flagship mobile chipsets will be the first to feature WiFi 7, but this could be an over-optimistic guess.

Penta-Band Mesh & MLO

Two of the interesting features of the brief included panta-band support and MLO.

Multi-Link Operation is one of the standout features of WiFi 7. This allows separate bands to be combined for increased throughput.

What was new to me was the pentaband support. With WiFi 5 you had triband with a single 5Ghz band used for the backhaul. Then WiFi 6E brought with it quadband, giving you the three separate bands on the client end and a dedicated 5Ghz band between access points.

Thanks to MLO, you can now have a fifth band allowing a 5Ghz and 6Ghz band for backhaul. This would maximise throughput while avoiding the range issues you’d face trying to use just 6Ghz as the backhaul.

With a 4×4 radio using MLO you’d have a theoretical 19Gbps fronthaul and 17Gbps on the backhaul.
