ASUS has introduced its flagship dual-band AC3100 wireless PCIe x1 adapter with four antennas and a maximum supported throughput of 2167 Mbps (270 MB/s). The card is powered by Broadcom’s flagship 802.11ac Wave 2 system-on-chip for Wi-Fi adapters and to show its best, it has to be connected to a router featuring another high-end Broadcom SoC.

The ASUS dual-band AC3100 wireless (PCE-AC88) PCIe adapter is based on the Broadcom BCM4366 SoC introduced early last year. The BCM4366 supports 4x4 802.11ac MU-MIMO technology and can thus use four 802.11n (2.4 GHz/5 GHz) or four 802.11ac (5 GHz) streams. The PCE-AC88 is a small half-height card that features PCIe x1 interface (the Broadcom chip supports PCIe 3.0, but exact data rate of the card is not given) and is equipped with a large big red cooler, and it is particularly large compared to other WiFi heatsinks. The device features four RP-SMA connectors for antennas as well as a special external magnetic base for the antennas which may be installed on top of a desktop PC or positioned somewhere else for better radio performance.
