Investing in the Cisco Aironet 1852E Access Point (AIR-AP1852E-B-K9C) ensures you harness the full potential of 802.11ac Wave 2 technology, capable of supporting high-density environments with multiple clients such as smartphones, tablets, and laptops. With its 4×4 MIMO four-spatial-stream configuration, this access point provides significant improvements in user experience by increasing throughput and reducing latency during peak usage times.
One of the key advantages of the AIR-AP1852E-B-K9C is its adaptability. The external antennas offer flexible mounting options, making it easy to optimize coverage patterns for maximum efficiency across varied deployment scenarios. Additionally, the access point supports both single-user and multiuser MIMO, making it capable of communicating with multiple devices concurrently, vastly improving network efficiency and user bandwidth.
Ease of setup is another benefit, as it comes preconfigured with the Cisco Mobility Express solution, allowing for simple and fast configuration without the need for a physical controller. Network administrators can easily manage the system, reducing setup time and costs.
Furthermore, the AIR-AP1852E-B-K9C model operates within the B Regulatory Domain, providing compliance with regional regulations for wireless communication. Employing this access point means you can confidently expand your network’s wireless capacity with a product designed for optimal performance and regulatory adherence.
Choosing Cisco’s Aironet 1852E also sets a solid foundation for future-proofing your network infrastructure. As connected devices continue to evolve, having an access point capable of handling the demands of next-generation wireless standards is a savvy investment, ensuring your network remains capable and performant as new technologies emerge.
AIR-AP1852E-B-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-B-K9C provides B Regulatory Domain and External antennas. Model number ending in C is, by default, factory-shipped with a Cisco Mobility Express software image.
