The Cisco Aironet 1852i Access Point, AIR-AP1852I-BK910, stands out as a leading enterprise-grade solution for any small to medium-sized business or organization requiring robust, high-speed wireless connectivity. With the AIR-AP1852I-BK910’s support for the latest 802.11ac Wave 2 standard, it delivers speeds up to 1.7 Gbps that can efficiently handle more devices and high-bandwidth activities like streaming and video conferencing. What makes this access point particularly relevant for modern wireless networks is its implementation of Multiuser MIMO (MU-MIMO), which enables it to communicate with multiple devices simultaneously, reducing wait time, and significantly improving user experience.

Furthermore, the access point’s 4×4 MIMO with four spatial streams allows a wider coverage area and enhanced performance. It also facilitates better network reliability through features such as Maximal Ratio Combining (MRC), beamforming, and support for 20-, 40-, and 80-MHz channels.

Deployment flexibility is another critical feature of the Aironet 1852i. With its internal antennas and support for B Regulatory Domain, it is ready for installation in a wide range of geographical regions, meeting regulatory compliance while minimizing setup complexity. Safety is enhanced, thanks to integrated 802.11 DFS (Dynamic Frequency Selection) that helps avoid interference with radar signals.

Administrators will benefit from the access point’s intuitive management features, whether deploying a single AP or a large network. The included ports and interfaces offer options for connectivity and power (including PoE), while the model’s scalability ensures that growing network demands can be met with ease.

For organizations valuing uptime, the pack of 10 access points ensures redundancy, so business operations continue unhindered if an AP goes down. All these features, combined with Cisco’s reputation for reliability, make the AIR-AP1852I-BK910 a sound investment for creating or upgrading a wireless network ready to tackle the challenges of modern digital demands.

AIR-AP1852I-BK910 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-BK910 provides B Regulatory Domain and internal antennas. It also ships with 10 access points.
