Support & Resources
Aironet 1852I-E-K9 Wi-Fi Access Point, 802.11ac Wave 2, with internal antenna (AIR-AP1852I-E-K9)
- MU-MIMO: 802.11ac Wave 2 with 4x4 Multiple-Input Multiple-Output (MIMO) technology with four spatial streams when operating in single-user MIMO mode and three spatial streams while operating in multi-user MIMO mode, offering 1.7 Gbps rates for more capacity and reliability than competing 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
- SECURITY: Securing the Device: Cisco Umbrella (OpenDNS), Identity PSK (iPSK), IP and DNS ACLs. Securing the Air: Spectrum Intelligence, Wireless Intrusion Detection (WIDS). Securing the Network: 802.1x on AP, AAA profiling and policy
- PEACE OF MIND: Limited lifetime hardware warranty
