Dual 5 GHz radio role, with both radios operating in the 5 GHz band, actively serving client
devices to maximize the benefits of 802.11ac Wave 2 and to increase client device capacity.
–
Wireless Security Monitoring and 5 GHz role, where one radio serves 5 GHz clients, while the
other radio scans both 2.4 GHz and 5 GHz for wIPS attackers, CleanAir interferers, and
rogue devices.
• Multiuser Multiple-Input Multiple-Output (MU-MIMO) technology with 3 spatial streams.
• Cross-AP Noise Reduction, a Cisco innovation that enables APs to intelligently collaborate in real
time about RF conditions so that users connect with optimized signal quality and performance.
• Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage
range that offers the fastest data rate available.
• Cisco ClientLink 4.0 technology for improved downlink performance to all mobile devices,
including one-, two-, and three-spatial-stream devices up to 802.11ac Wave 1 and Wave 2. The
technology also improves battery life on mobile devices.
• Cisco CleanAir technology enhanced with 160MHz channel support. CleanAir delivers proactive,
high-speed spectrum intelligence across 20-, 40-, and 80-, and 160-MHz-wide channels to combat
performance problems arising from wireless interference.
• MIMO equalization capabilities, which optimize uplink performance and reliability by reducing
the impact of signal fade.
The AP supports the following operating modes:
• Centralized
• Sniffer
• FlexConnect
• Monitor Mode
• Service Provider Option 60 (DHCP Option 60)
