ASUS today announced PCE-AC88, a dual-band 802.11ac Wi-Fi PCI Express® (PCIe®) adapter that instantly upgrades a desktop PC to the latest ultra-fast wireless standard. PCE-AC88 is the first PCIe adapter to feature a 4x4 (4 transmit, 4 receive) MIMO design that delivers AC3100-class speeds of up to 2100Mbps on the 5GHz band and 1000Mbps on the 2.4GHz band. For the best signal reception, PCE-AC88 includes a magnetic antenna base that allows flexible placement of the four detachable external antennas on any suitable surface. PCE-AC88 allows PC users to take advantage of the latest high-speed 802.11ac routers, which offer wireless speeds that match or exceed wired Gigabit Ethernet networking speeds. When paired with a 4x4 802.11ac router, PCE-AC88 unleashes the full performance and coverage potential of the 4x4 MIMO technology, but it is also backward-compatible with all existing Wi-Fi standards.
