The advantages of 802.11ac are multiuser MIMO communications, optionally 160 MHz wide channels, and completely moving out of the crowded 2.4 GHz band. MIMO requires somewhat more processing power on the receiving end to process, and a different antenna design. However, the dramatically increased speeds, combined with the release of devices that support 802.11ac, make it a worthwhile consideration for upgrading your wireless network.
Aruba’s 320 Series features support for 802.11ac Wave 2, in 4X4:3 configuration for MU-MIMO (rated at up to 1,300 Mbps), and 4X4:4 for SU-MIMO (rated at up to 1,733 Mbps). Being an enterprise-grade access point, it can support 255 users per radio. The AP-325 (left) contains eight integrated omni-directional downtilt antennas, while the AP-324 (right) has four dual-band external RP-SMA antenna connectors.
