Flexible Radio
Assignment
Assignment
Allows the access points to intelligently determine the operating mode of serving radios based on the RF
environment. The access points can operate in the following modes:
environment. The access points can operate in the following modes:
● 2.4-GHz and 5-GHz mode: One radio will serve clients in 2.4-GHz mode, while the other serves clients in 5-
GHz mode.
● Dual 5-GHz mode: Both radios inside the access point operate on the 5-GHz band, maximizing the benefits of
802.11ac Wave 2 and increasing client device capacity.
● Security Monitoring and 5-GHz mode, One radio will serve 5-GHz clients, while the other is scanning the full
spectrum for wIPS attackers, CleanAir interferers, and rogue devices.
Dual 5-GHz radio support
Enables both radios to operate in 5-GHz client serving mode, allowing an industry-leading 5.2 Gbps (2 x 2.6 Gbps)
over-the-air speeds while increasing client capacity.

Smart antenna connector An intelligent second physical antenna connector is included on 2800 Series models with an external antenna. This
connector provides advanced network design flexibility for high-density and large open-area environments such as
auditoriums, convention centers, libraries, cafeterias, and arenas/stadiums, allowing two sets of antennas to be
connected and active on a single access point.

160-MHz channel support Supporting channels up to 160 MHz wide, Dynamic Bandwidth Selection allows the access point to dynamically
switch between 20-, 40-, 80-, and 160-MHz channels, depending on the RF channel conditions, providing the
industry’s best-performing wireless network.

802.11ac Wave 2 and Beyond
The Aironet 2800 Series extends 802.11ac speed and features to a new generation of smartphones, tablets, and
high-performance laptops, providing a greater end-user experience. Whether your project involves wholesale
changes to your current wireless network or upgrading your legacy Wi-Fi deployments (802.11a/b/g/n/ac wave 1
deployments), the 2800 Series can handle the job.
The 2800 Series supports 802.11ac Wave 2, providing a theoretical connection rate of up to 5.2 Gbps
—that’s
roughly 4x the rates offered by today’s high-end 802.11ac access points. The boost helps you stay ahead of the
performance and bandwidth expectations of today’s mobile worker, who usually uses multiple Wi-Fi devices
performance and bandwidth expectations of today’s mobile worker, who usually uses multiple Wi-Fi devices
instead of just one. As such, users are adding proportionally larger traffic loads to the wireless LAN, which has
outpaced Ethernet as the default enterprise access network.
Cisco DNA Support
Pairing the 2800 Series access points with the Cisco Digital Network Architecture (DNA) allows for a total network
transformation. Cisco DNA allows you to truly understand your network with real-time analytics, quickly detect and
contain security threats, and easily provide networkwide consistency through automation and virtualization. By
decoupling network functions from the hardware, you can build and manage your entire wired and wireless network
from a single user interface.
