Wi is Fi: Understanding Wi-Fi 4/5/6/6E/7/8 (802.11 n/AC/ax/be/bn)

Wi-Fi technology evolution (Wi-Fi 4 through 8) is rapidly advancing to keep pace with broadband speeds, but CIOs must recognize that client device capabilities—not router specifications—are the primary constraint limiting organizational wireless performance, with most devices capped at 2×2 MIMO delivering ~900 Mbps on Wi-Fi 6. Marketing claims of aggregate multi-gigabit speeds are misleading; IT leaders should focus procurement decisions on practical metrics like DFS channel support, 160 MHz capability, and real-world distance performance rather than manufacturer hype. Strategic investment in mid-range Wi-Fi 6 access points and understanding client limitations will yield better ROI than pursuing cutting-edge Wi-Fi 7/8 infrastructure prematurely.
