NDIS 6 supports exposing 802.11 frames to the upper protocol levels, [2] while previous versions only exposed fake Ethernet frames translated from the 802.11 frames. Monitor mode support in NDIS 6 is an optional feature and may or may not be implemented in the client adapter driver.

Generic 802.11 Frame. The very first two octets transmitted by a station are the Frame Control. The first three subfields within the frame control and the last field are always present in all types of 802.11 frames. These three subfields consist of two bits Protocol Version subfield, two bits Type subfield, and four bits Subtype subfield.
The feature has been implemented for the first time into Microsoft operating systems in Windows 8. This has caused a number of compatibility issues particularly with wireless access points that are not compatible with the standard. Rolling back the wireless adapter driver to one from Windows 7 usually fixes the issue.
IEEE 802.11 RTS/CTS (request to send/clear to send) is the optional mechanism used by the 802.11 wireless networking protocol to reduce frame collisions introduced by the hidden node problem. Originally the protocol fixed the exposed node problem as well, but later RTS/CTS does not, but includes ACKs.
Xpress technology is Broadcom's standards-based frame-bursting approach to improve 802.11 wireless LAN performance. It is a software-based implementation of the frame-bursting originally in the IEEE 802.11e draft specification, and is found in the Wireless Multimedia Extensions (WME) specification.
In protocol standards and implementations, the frame aggregation is usually combined with segmentation and reassembly of frames so that the time slots can be filled to 100%. E.g., an aggregation MAC PDU can be filled with 3.5 frames to ensure the time slot is utilized to 100% and in the next time slot the rest of the fragmented frame is sent ...
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 ...
