Wi-Fi 6

Rare card · No. 48115

IEEE 802.11ax-2021, or 802.11ax, is an IEEE standard from the Wi-Fi Alliance for wireless networks (WLANs). The standard is marketed as Wi-Fi 6. It operates in the 2.4 GHz and 5 GHz bands, with an extended version, Wi-Fi 6E, that adds the 6 GHz band; these are license-exempt ISM bands. It is an upgrade from Wi-Fi 5 (IEEE 802.11ac), with improvements for better performance in crowded places. This standard aims to boost throughput in crowded places like offices and malls. Though the nominal data rate is only 37% higher than that of Wi-Fi 5, the throughput increases by at least four times, making it more efficient and reducing latency by 75%. The quintupling of overall throughput is made possible by higher spectral efficiency. Wi-Fi 6 has a main feature called OFDMA, similar to how cellular common-carrier networks work. This brings better spectrum use, improved power control to avoid interference, and enhancements like 1024‑QAM, MIMO and MU-MIMO for faster speeds. There are also reliability...
