The AIR‑AP2802I‑E‑K9 is a Cisco Aironet 2800 Series enterprise-class wireless access point designed for demanding indoor environments. It implements 802.11ac Wave 2 technology and delivers robust connectivity with internal antennas in the E regulatory domain. This model is ideal for large-scale deployments, offering high‑throughput, seamless roaming, and intelligent RF management.
Core Features
802.11ac Wave 2 & MU-MIMO
Supporting 4x4 MU‑MIMO with three spatial streams and beamforming, the AIR‑AP2802I‑E‑K9 can deliver theoretical PHY rates up to 5.2 Gbps across dual‑band radios (2.4 GHz and 5 GHz).
Flexible Radio Assignment & HDX
Equipped with Cisco’s Flexible Radio Assignment, it can dynamically assign its dual radios into multiple modes: dual‑band serving, dual 5 GHz client service, or security monitoring. Combined with High‑Density Experience architecture—including CleanAir® interference mitigation, ClientLink 4.0, and cross‑AP noise control—this ensures top-tier performance in crowded deployments.
Internal Antenna & Regulatory Domain
The AIR‑AP2802I‑E‑K9 includes internal omnidirectional antennas optimized for the E regulatory domain: 2.412–2.472 GHz and multiple 5 GHz ranges (excluding 5.600‑5.640 GHz). This compact design supports aesthetic installations while meeting regulatory compliance requirements.
