Features
- MU-MIMO: 802.11ac Wave 2 with 4×4 Multiple-Input Multiple-Output (MIMO) technology with three spatial streams, offering connection rate of up to 2.6 Gbps per radio – roughly double the rates offered by today’s high-end 802.11ac access points
- APPLICATION VISIBILITY AND CONTROL: Network Based Application Recognition (NBAR) deep-packet inspection technology provides application-aware control on a wireless network and enhances manageability and productivity. It also extends Cisco’s Application Visibility and Control (AVC) as an end-to-end solution, which gives a complete visibility of applications in the network and allows the administrator to take some action on the same.
- RADIO RESOURCE MANAGEMENT: Cisco’s Radio Resource Management (abbreviated RRM) allows Cisco’s Unified WLAN Architecture to continuously analyse the existing RF environments, automatically adjusting each AP’s power and channel configurations to help mitigate things such as co-channel interference and signal coverage problems. RRM reduces the need to perform exhaustive site surveys, increases system capacity and provides automated self-healing functionality to compensate for RF dead zones and AP failures
- FLEXIBLE RADIO ASSIGNMENT: Software-defined radio automatically adjusts to dual 5 GHz increasing capacity to onboard more users and things automatically
- HDX HIGH DENSITY EXPERIENCE: Award-winning CleanAir to mitigate Wi-Fi and non-Wi-Fi interference, ClientLink to conserve battery life on mobile devices

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 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
The Cisco AIR‑AP2802I‑E‑K9 is supported in Cisco Digital Network Architecture (Cisco DNA) allows for a total network transformation. but whether you need DNA licensing, and what features you get, depends on your setup (which controller, which firmware, and what DNA tier). I’ll break down the details, so you can see whether in your case DNA support applies, or is needed.
What is “DNA” in this context
-
Cisco DNA (Digital Network Architecture) is Cisco’s subscription/licensing platform for newer networks. It covers visibility, automation, policies, security, analytics, etc. For wireless, DNA involves software subscriptions (e.g. DNA Essentials, DNA Advantage) on controllers (like Catalyst 9800) and sometimes also on the APs. Depending on the controller type (AireOS, Catalyst 9800, etc.), the AP licensing / requirement differs.
Working together, the 2800 Series and Cisco DNA offer such features as:
● Flexible Radio Assignment
● And much more
High-density experience
Here’s a breakdown of “High‑Density Experience (HDX)” as it relates to the Cisco AIR‑AP2802I‑E‑K9 / 2800 Series, what features enable it, and what you get in practice. If you tell me your deployment size (number of clients, area, building layout), I can help you estimate whether HDX will deliver well in your environment. HDX is Cisco’s suite of features (hardware + software + RF design) for handling many wireless clients in one place — think auditoriums, lecture halls, open‑plans, conference centers. It’s meant to improve user experience when many devices are competing for RF spectrum, including legacy (2.4 GHz) and modern (5 GHz / Wave 2) devices
Cross‑AP Noise Reduction / Optimized Roaming Helps when many APs are deployed: reduces interfering overlap, helps clients roam smoothly between APs so they always get good signal and performance.
Cisco ClientLink 4.0 technology to improve downstream performance to all mobile devices, including one-, two-, and three-spatial-stream devices on 802.11a/b/g/n/ac. At the same time, the technology improves battery life on mobile devices, helps reach connection quality; antenna flexibility for certain models to deal with specific coverage challenges.
Dual 5 GHz mode Both radios operating in 5 GHz (if spectrum available and client devices support it) to increase capacity, reduce congestion and interference
Flexible Radio Assignment (FRA)Allows radios to adapt depending on density and RF environment: e.g. one radio serving 5 GHz, or both radios serving 5 GHz (if many high‑capacity devices), or one radio used for monitoring/security/scan while the other serves clients. This maximizes performance depending on conditions
Cisco CleanAir technology enhanced with 160-MHz channel support. CleanAir delivers proactive, high-speed spectrum intelligence across 20-, 40-, and 80-, and 160-MHz* wide channels to combat performance problems due to wireless interference. It detects interference sources (Wi‑Fi and non‑Wi‑Fi), helps mitigate. Improves reliability in noisy RF environments
MIMO equalization capabilities, which optimize uplink performance and reliability by reducing the impact of signal fade.
802.11ac Wave 2 with MU‑MIMO (4×4 with 3 spatial streams)Enables simultaneous transmission to multiple clients, improving throughput in busy environments.
What You Should Expect in Practice with HDX on the 2802I‑E
If you deploy the AIR‑AP2802I‑E‑K9 correctly in a high‑density scenario, here’s what you (and users) can expect:
- Better capacity: more clients can be serviced without undue degradation in throughput.
- More stable connections: less dropped/stuck throughput during busy periods.
- Higher throughput for modern devices (especially those that support 5 GHz, wave 2, MU‑MIMO).
- Lower interference effects, thanks to CleanAir + radio adjustments.
- Flexible deployment options: ability to tune radios / channels for density.
However, there are limitations and things to plan well to get full benefit:
- Spectrum availability: if your 5 GHz environment is constrained (regulatory limits, many neighbours, interference), you may be limited.
- Physical layout: coverage, walls, ceilings, materials will reduce performance. Even HDX can’t override bad placement.
- Client device capability: many older devices don’t support MU‑MIMO, only use 2.4 GHz, etc. Those will still drag down performance somewhat.
- Power & backhaul: PoE+ is needed; also the wired infrastructure must support handling the increased traffic (switch ports, uplinks etc.).
