THE CISCO AIRONET 1815I DELIVERS INDUSTRY-LEADING WIRELESS PERFORMANCE WITH SUPPORT FOR THE LATEST WI-FI STANDARD, IEEE’S 802.11AC WAVE 2 (FIGURE 1). IT ALSO MEETS THE GROWING REQUIREMENTS OF WIRELESS NETWORKS BY DELIVERING A BETTER USER EXPERIENCE. THE 1815I EXTENDS SUPPORT TO A NEW GENERATION OF WI-FI CLIENTS, SUCH AS SMARTPHONES, TABLETS, AND HIGH-PERFORMANCE LAPTOPS THAT HAVE INTEGRATED 802.11AC WAVE 1 OR WAVE 2 SUPPORT.

MULTIUSER (MU) MULTIPLE-INPUT MULTIPLE-OUTPUT (MU-MIMO) ALLOWS TRANSMISSION OF DATA TO MULTIPLE 802.11AC WAVE 2–CAPABLE CLIENTS SIMULTANEOUSLY TO IMPROVE THE CLIENT EXPERIENCE. PRIOR TO MU-MIMO, 802.11N AND 802.11AC WAVE 1 ACCESS POINTS COULD TRANSMIT DATA TO ONLY ONE CLIENT AT A TIME, TYPICALLY REFERRED TO AS SINGLE-USER MIMO (SU AND #8209;MIMO). 802.11AC WAVE 2 WITH 2X2:2 MIMO TECHNOLOGY USES TWO SPATIAL STREAMS WHEN OPERATING IN SU-MIMO OR MU-MIMO MODE, OFFERING 867-MBPS RATES FOR MORE CAPACITY AND RELIABILITY THAN COMPETING ACCESS POINTS.
