The Aruba AP-224 and AP-225 wireless access points support the IEEE 802.11ac
standard for high-performance WLAN. This access point uses MIMO (Multiple-in,
Multiple-out) technology and other high-throughput mode techniques to deliver
high-performance, 802.11n 2.4 GHz and 802.11ac 5 GHz functionality while
simultaneously supporting existing legacy wireless services. The AP-220 Series
access point works only in conjunction with an Aruba Controller.
