AIR-AP1852I-C-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 4×4 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-AP1852I-C-K9 provides C Regulatory Domain and internal antennas.
