Key Takeaways
- Speed: Wi-Fi 6 (802.11ax) is about 40% faster than Wi-Fi 5 (802.11ac).
- Congestion: It handles many devices (phones, IoT, laptops) much better at the same time.
- OFDMA: A technology that splits channels to send data to multiple devices at once.
- Battery: "Target Wake Time" helps devices save energy.
Wi-Fi 5 was built for a world where you had one laptop and one phone. Wi-Fi 6 is built for the modern smart home with 50 connected devices fighting for bandwidth.
The Secret Sauce: OFDMA
Imagine a delivery truck (Wi-Fi Packet).
In Wi-Fi 5, the truck could only carry one package to one house at a time, even if the truck was mostly empty.
In Wi-Fi 6, the truck can carry packages for 5 different houses in the same trip.
This is called Orthogonal Frequency-Division Multiple Access (OFDMA), and it drastically reduces lag when multiple people are streaming or gaming.
Do I need a new router?
Yes. To get Wi-Fi 6 speeds, you need a Wi-Fi 6 router and a Wi-Fi 6 device (like an iPhone 11 or newer, or a modern laptop). If you connect an old laptop to a Wi-Fi 6 router, it will still work, but at older speeds.
