Wi-Fi 6, or IEEE 802.11ax, is an IEEE standard from the Wi-Fi Alliance, for wireless networks . It operates in the 2.4 GHz and 5 GHz bands, [ 9 ] with an extended version, Wi-Fi 6E , that adds the 6 GHz band. [ 10 ]
This time period is called a beacon period (BP). At the beginning of each BP, there is a beacon generation window consisting of w + 1 {\displaystyle w+1} slots each of length aSlotTime . Each station calculates a random delay uniformly distributed in [ 0 , w ] {\displaystyle [0,w]} and is scheduled to transmit a beacon when the delay timer expires.
Traffic indication map (TIM) is a structure used in 802.11 wireless network management frames. The traffic indication map information element is covered under section 7.3.2.6 of 802.11-1999 standard. [1] The IEEE 802.11 standards use a bitmap to indicate to any sleeping listening stations that the access point (AP) has buffered data waiting for it.
In the IEEE 802.11 wireless LAN protocols (such as Wi-Fi), a MAC frame is constructed of common fields (which are present in all types of frames) and specific fields (present in certain cases, depending on the type and subtype specified in the first octet of the frame). Generic 802.11 Frame
Short Interframe Space (SIFS), is the amount of time in microseconds required for a wireless interface to process a received frame and to respond with a response frame. It is the difference in time between the first symbol of the response frame in the air and the last symbol of the received frame in the air.
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
