Cisco 1852E Series Aironet Wireless Wifi Access Point AP AIR-AP1852E-D-K9
AIR-AP1852E-D-K9 is one of the Cisco Aironet 1850 Series Access Points. Cisco 1850 AP
series is ideal for small and medium-sized networks. This series supports enterprise-class
4x4 MIMO, four-spatial-stream access points that support the IEEE’s new 802.11ac Wave 2
specification. The 1850 Series extends support to a new generation of Wi-Fi clients, such as
smartphones, tablets, and high-performance laptops that have integrated 802.11ac Wave 2
support. The model AIR-AP1852E-D-K9 provides E Regulatory Domain and External antennas.

The Aironet 3800 Series is packed with the features and capabilities that have made Cisco the industry leader, at a
price point that is ideal for managing wireless growth, capacity, and coverage gaps in dense indoor environments.
With the 3800 Series, you can secure remote workers or the micro-office. Any Cisco Aironet or Catalyst access point
can function as an OfficeExtend Access Point (OEAP). With an OEAP, an employee at home or in a temporary
micro-office will have access to the corporate SSID and the corporate network without the need to set up a VPN or
have any advanced technical know-how.
Cisco User Defined Network, a feature available in Cisco DNA Center, allows IT to give end users control of their very
own wireless network partition on a shared network. End users can then remotely and securely deploy their devices on
this network. Perfect for university dormitories or extended hospital stays, Cisco User Defined Network grants both
device security and control, allowing each user to choose who can connect to their network.
