IEEE 802.11be, dubbed Extremely High Throughput (EHT), is a wireless networking standard in the IEEE 802.11 set of protocols [9] [10] which is designated Wi-Fi 7 by the Wi-Fi Alliance. [ 11 ] [ 12 ] [ 13 ] It has built upon 802.11ax , focusing on WLAN indoor and outdoor operation with stationary and pedestrian speeds in the 2.4, 5, and 6 GHz ...

802.11b has a maximum raw data rate of 11 Mbit/s and uses the same CSMA/CA media access method defined in the original standard. Due to the CSMA/CA protocol overhead, in practice the maximum 802.11b throughput that an application can achieve is about 5.9 Mbit/s using TCP and 7.1 Mbit/s using UDP.
A candidate no longer has to pass an exam for the expert level Certified Wireless Network Expert (CWNE) certification. In addition to passing the CWNA, CWSP, CWAP and CWDP a candidate must also provide: 3 professional endorsements, 3 years of documented enterprise Wi-Fi experience, 2 other current valid networking certifications and ...
In 2018 The Wi-Fi Alliance created the simpler generation labels Wi-Fi 4 - 6 beginning with Wi-Fi 5, retroactively added Wi-Fi 4 and later added Wi-Fi 6 and Wi-Fi 6E. [24] [25] [26] Wi-Fi 5 had Wave 1 and Wave 2 phases. Wi-Fi 6E extends the 2.4/5 GHz range to 6 GHz, where licensed. Listed in historical and capacity order.
Common Wi-Fi routers and IoT devices (including those compliant with IEEE 802.11n/ac/ax/be, or Wi-Fi 4/5/6/7) predominantly operate within the sub-7 GHz range. The widespread global adoption of these frequencies has at times resulted in pronounced network congestion, particularly in the 2.4 GHz and 5 GHz bands.
