Wi-Fi 2.4G vs 5G vs 6G: What Actually Differs
2.4G, 5G, and 6G are often treated as three speed tiers of the same thing: 2.4G is slow but far-reaching, 5G is a bit faster, and 6G is the fastest. That is not entirely wrong, but it hides the most important engineering boundaries.
For Wi-Fi, these are first and foremost three different frequency bands. Only after that do you layer on 802.11 version, channel width, modulation and coding, terminal capability, and deployment conditions. In practice, the experience is usually determined not by “which G you chose,” but by which band you put which traffic on, and whether the device and the environment can actually support that path.
