WM-1431 802.11ax Dual Band Mini PCIe Wireless Module

General Description

1.1. Product Overview
WM-1431 is a 802.11ax Dual Band Mini PCIe wireless module, backward compatible with 802.11ac/a/b/g/n, the module was built based on MaxLinear WAV654 chipset (previous chipset named Intel WAV 654), which provide advanced 2x2x2 Concurrent Dual Band 802.11ax Wi-Fi systems. They are designed to support very high throughput, low latency, extra low host CPU consumption and enhanced reach and coverage. The PCIe 3.0 interface and Super Thick MAC acceleration allow the MaxLinear Home Wi-Fi Chipset WAV600 Series device to be connected to any network or media processor with minimal CPU load impact on the host processor, even with the maximum throughput of a 2×2 + 2×2 802.11ax system (up to 2.5 Gbps effective throughput).
WM-1431 supports 2T2R (2×2) Wi-Fi 6 technology, which runs up to 2,402Mbps at 5G or runs up to 574Mbps at 2.4G in theory. The WM-1431 supports 20/40 bandwidth in 2.4GHz band and 20/40/80/160 MHz bandwidth in 5GHz band.
