Choosing the Cisco Aironet 1852E, specifically the AIR-AP1852E-Z-K9 model, means selecting a top-tier access point catering to the needs of modern wireless networks. With enterprise-class 4×4 MIMO and support for up to four spatial streams, the device maximizes the efficiency of wireless communication. It is built to handle the latest Wi-Fi standard, 802.11ac Wave 2, offering significant bandwidth and user capacity improvements over its predecessors.
This AP is especially suited for small to medium-sized enterprises (SMEs) looking to deploy a robust wireless network without dealing with the complexity often associated with enterprise solutions. The inclusion of external antennas allows for a more flexible installation and the ability to tailor coverage to specific areas, ensuring optimal signal strength and reducing dead spots.
Equipped to support both Multi-User MIMO (MU-MIMO) and single-user MIMO (SU-MIMO), the Aironet 1852E can transmit to multiple devices simultaneously, improving throughput and efficiency. The high data rates of up to 1.7 Gbps make it not just future-proof but also capable of handling the heavy traffic associated with a large number of devices, including those that are 802.11ac Wave 2 enabled.
Security is a critical concern, and this access point delivers robust security features, ensuring safe communication channels for sensitive data. It supports 802.11r, which allows for fast roaming, a feature essential for environments where mobility is paramount.
For organizations requiring uninterrupted, high-speed wireless access for applications such as HD video streaming, large file transfers, and seamless voice communications, the Cisco Aironet 1852E is an excellent investment which ensures satisfying end-user experiences while providing the stability and reliability expected from a Cisco product.
AIR-AP1852E-Z-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-AP1852E-Z-K9 provides Z Regulatory Domain and External antennas.
