WNFQ-255ACN(BT)
802.11ac/abgn Dual-Band
2T2R Wi-Fi M.2 Module
The WNFQ-255ACN(BT) is powered by Qualcomm Atheros radio chip and features 2x2 11ac/abgn
technology for higher throughput performance, reliability and range. It is designed to meet the demanding
performance requirements of critical embedded applications. It supports 2T2R (Support WiFi/BT co-
existence) technology, which runs up to 867Mbps and 1~3Mbps EDR for BT. The WWNFQ-255ACN(BT)
supports 20/40/80MHz and 256-QAM to maximize bandwidth efficiency.
The QCA6174A is a single-die wireless local area network (WLAN) solution to support 2 × 2 multi-
user multiple input, multiple output (MU-MIMO) with two spatial streams IEEE802.11 a/b/g/n/ac
WLAN standards. It's engineered to deliver lower power consumption 1, improved RF coexistence 1, and
complete Microsoft Windows 10 support.
