The Cisco Aironet 1852E Access Point, model AIR-AP1852E-F-K9C, is a cutting-edge solution for small to medium-sized networks seeking enterprise-class performance. It stands out with 802.11ac Wave 2 technology, which supports multi-user MIMO (MU-MIMO). This feature means the access point can communicate with multiple devices simultaneously, substantially improving network efficiency and throughput. Its 4×4 MIMO with four spatial streams ensures robustness and increased data transfer rates, reaching speeds up to 1.7 Gbps, which is vital for bandwidth-intensive applications.
This model also includes Cisco Mobility Express, designed to streamline wireless network setup and operation without the complexity of traditional enterprise systems. The Cisco Mobility Express software is easy to deploy, without the need for a physical controller, making it cost-effective and less complex for businesses with limited IT resources.
Robust security is another crucial factor for any wireless network, and the AIR-AP1852E-F-K9C delivers with advanced encryption and authentication protocols to protect sensitive data. Cisco’s commitment to security ensures that your wireless network is safeguarded against threats.
External antennas offer the flexibility to optimize coverage and signal reliability in challenging environments. These antennas can be positioned for maximal range and coverage, adapting to any physical office layout or location demands.
Additionally, investment protection is assured with the AIR-AP1852E-F-K9C’s support for both older 802.11n devices and the newest 802.11ac Wave 2 standards. This backward compatibility coupled with future-proofing means your network is ready for the next generation of wireless devices.
Finally, choosing a reputable brand like Cisco ensures that you have access to global support and a comprehensive warranty, providing peace of mind that you have reliable assistance whenever needed. This makes the Cisco Aironet 1852E Access Point an intelligent purchase for businesses looking for durability, high performance, and scalability.
AIR-AP1852E-F-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-F-K9C provides F Regulatory Domain and External antennas. Model number ending in C is, by default, factory-shipped with a Cisco Mobility Express software image.
