Webtransmitter measurement for a WLAN station to a specific MCS in signaling mode. Uplink OFDMA synchronization One of the prerequisites for efficient parallel operation of mul-tiple WLAN ax stations is proper synchronization. Triggered by the AP, all stations must start transmitting within ±0.4 µs, (Fig. 2). 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). The very first two octets transmitted by a station are the Frame Control. The fir…
