The Asus RT-AC86U is a commercial IEEE 802.11ac Wi-Fi router built on a Broadcom BCM4366E chipset, which supports operation on 80 MHz bandwidth channels and is capable of transmitting and receiving signals across multiple antennas. It is significant in the CSI sensing research community because it is one of the devices supported by the nexmon CSI Extractor Tool, enabling researchers to extract per-frame Channel State Information from commodity hardware without requiring specialized equipment. Its support for wide-band 80 MHz channels makes it particularly valuable for high-resolution wireless human sensing datasets, as wider bandwidth yields finer delay-domain resolution and richer subcarrier information compared to earlier 20 or 40 MHz setups.
