BW1684-PCIEB is a single-band(2.4GHz) 4*4 Wi-Fi 6 module.

The module enables the development of advanced high-efficiency wireless Wi-Fi 6 access points, repeaters,and WLAN client solutions. Wi-Fi 6 introduces Orthogonal Frequency-Division Multiple Access(OFDMA) to enhance the multi-user experience. It is an evolutionary step forward from Wi-Fi 5 in that it allows multi-client transmissions in both the uplink and downlink directions. OFDMA multiplexes clients across frequency instead of spatial streams to allow for more concurrent users than MU-MIMO. BW1684-PCIEB supports 40MHz channels and IEEE standardized 1024-QAM modulation. These combined with a 4x longer OFDM symbol length,allow for a maximum PHY rate of 1.15Gbps.It is backward compatible to previous generations and supports MU-MIMO from Wi-Fi 5. Embedded hardware acceleration enables increased system performance and significant reduction in host-CPU utilization in both client and access point(AP) configurations.
