4×4 MU-MIMO WiFi 6 module for the 5GHz band, Mini PCIe Module, Qualcomm Atheros QCN9074, 4T4R


The first WiFi-6 (802.11ax) Qualcomm based AP solution on module formfactor from SparkLAN. WPEQ-405AX, is based on QCN9074 chipset solution. This is a true enterprise based wireless module that powers 4T4R (4×4) MU-MIMO, in 5Ghz Single band mode, hitting a theoretical speed of up to 4.8Gbps with 160MHz support.

Unlike typical Qualcomm reference design around QCN9074 (PN02.1), WPEQ-405AX shrink the traditional 50mmx50mm M.2 E-Key design to a more popular Mini PCIe Full size formfactor of just 50mm x 30mm, run at 3.3V voltage. Provides a greater versatility to use on more common seen design.

WPEQ-405AX performs both AP and STA functionality with 4 spatial streams, although recommended more for hardware AP applications as it supports 4096-QAM, OFDMA technology, makes it perfect for heavy lifting applications such as Enterprise grade AP, UTM, public [&] transportation Hotspot, and other industrial capable Access Points.
