As the latest Wi-Fi standard defined in IEEE 802.11, 802.11ax improves the user access capacity and bandwidth in
high-density access scenarios, reduces service latency, and enhances user experience.
⚫ Multi-user multiple-input multiple-output (MU-MIMO) on both the 2.4 GHz and 5 GHz frequency bands, allowing
an AP to transmit data to and receive data from multiple STAs simultaneously and multiplying the utilization of
radio spectrum resources.
⚫ 802.11ax supports 1024-QAM, delivering 25% higher data transmission efficiency than 802.11ac (supporting
256QAM).
⚫ Orthogonal Frequency Division Multiple Access (OFDMA) technology enables the AP to transmit data to multiple
STAs at the same time using different subcarriers, reducing latency and improving network efficiency.
⚫ Spatial multiplexing technology uses basic service set (BSS) coloring mechanism to enable the AP and STAs to
distinguish overlapping BSSs, minimizing co-channel interference.
⚫ Target Wake Time (TWT) technology allows the AP and STAs to negotiate the sleep and wake time with each other,
thereby improving the battery life of the STAs.
