Cisco’s Aironet 1852E Access Point (AIR-AP1852E-T-K9C) is a cutting-edge networking solution bringing enterprise-class features to businesses requiring robust, reliable Wi-Fi. With IEEE’s 802.11ac Wave 2 support and 4×4 MIMO technology, the AP accommodates a more significant number of clients and offers faster data transmission, crucial for environments with high-client density. Multiuser MIMO enables multiple clients to receive data simultaneously, increasing user throughput and network efficiency.
This AP also aligns with the latest Wi-Fi standards, solidifying your network’s future-proofing by supporting new Wave 2 devices. Despite its advanced capabilities, the Cisco Aironet 1852E is designed for easy deployment without extensive IT expertise, thanks to the pre-installed Cisco Mobility Express software.
With the T Regulatory Domain, this device is tailored to operate within specific geographic locations, ensuring compliance with local wireless regulations. Four external antennas facilitate superior coverage and signal quality, extending reach and reliability. Moreover, it delivers an enhanced user experience with PHY data rates up to 1.7 Gbps, making it ideal for data-intensive applications like streaming video, collaborative work, and cloud computing.
Options for power include PoE, allowing for flexibility in installation, especially in areas without convenient power outlets. The access point’s sleek design and mountable form factor mean it can be strategically placed for optimal performance without disrupting workplace aesthetics.
Investing in the Cisco Aironet 1852E Access Point represents a commitment to a secure, high-speed wireless network that meets the demands of modern businesses and ensures users remain connected and productive.
AIR-AP1852E-T-K9C 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-AP1852E-T-K9C provides T Regulatory Domain and External antennas. Model number ending in C is, by default, factory-shipped with a Cisco Mobility Express software image.
