The Wi-Fi Alliance officially launched the Wi-Fi 7 certification standard, sparking debates on whether homeowners and gamers need to upgrade their existing Wi-Fi 6 (802.11ax) routers. Here is what actually changed under the hood.
1. Channel Width Doubled to 320 MHz
In Wi-Fi 6 and 6E, the maximum single contiguous channel bandwidth was 160 MHz. Wi-Fi 7 doubles this to 320 MHz in the pristine 6 GHz spectrum band, delivering theoretical peak transfer speeds exceeding 40 Gbps.
2. Multi-Link Operation (MLO)
Traditionally, a phone or laptop connects to either the 2.4 GHz, 5 GHz, or 6 GHz frequency band. With Multi-Link Operation (MLO), a Wi-Fi 7 client transmits and receives data across multiple frequency bands simultaneously. This drastically slashes latency and virtually eliminates buffering spikes during competitive gaming and video calls.
Should You Upgrade Now?
If you already own a robust Wi-Fi 6 router and gigabit internet, upgrading immediately may offer diminishing returns until more client devices (laptops, phones) have Wi-Fi 7 chipsets. However, if your current router is older Wi-Fi 5 (802.11ac) or struggles with network congestion in crowded apartment complexes, jumping straight to Wi-Fi 7 provides future-proof performance.
