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.
ā« 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.
ā« 802.11ax supports 1024-QAM, delivering 25% higher data transmission efficiency than 802.11ac (supporting
256QAM).
ā« 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.
ā« Spatial multiplexing technology uses basic service set (BSS) coloring mechanism to enable the AP and STAs to
distinguish overlapping BSSs, minimizing co-channel interference.
ā« 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.
