AIR-AP1852E-E-K9 Cisco Wifi AP 802.11ac Wave 2 4x4 MU-MIMO External Antenna for Flexible Coverage

Cisco AIR-AP1852E-E-K9: Adaptable Wi-Fi 5 with External Antenna Flexibility

The Cisco AIR-AP1852E-E-K9 is a robust 802.11ac Wave 2 Cisco Wireless AP designed for medium-sized enterprises and environments requiring flexible wireless coverage through external antennas. It delivers high performance and enhances client experiences in diverse settings.

High-Speed Wave 2 Performance

This Cisco Wireless AP offers 4x4 MU-MIMO with four spatial streams on the 5 GHz band, achieving theoretical data rates up to 1.7 Gbps. With additional 4x4 MIMO on the 2.4 GHz band (up to 600 Mbps), it provides a total aggregated dual-radio data rate of up to 2 Gbps, ensuring high capacity for numerous devices.

Flexible Coverage with External Antennas

The key differentiator of the 1852E-E-K9 lies in its four RP-SMA connectors for external antennas (sold separately). This allows network administrators to choose specialized antennas to precisely control coverage patterns, optimize signal strength, and adapt to challenging RF environments like warehouses, large open areas, or industrial settings, offering more versatility than fixed-antenna models.

Streamlined Management & Deployment

The AIR-AP1852E-E-K9 supports Cisco Mobility Express, enabling a controller-less setup for up to 25 access points – perfect for quick, cost-effective deployments without a dedicated Cisco Network Switch controller. For larger or more complex networks, it integrates seamlessly with Cisco Wireless LAN Controllers and Cisco DNA Center for centralized control.

Optimized for Modern Devices

Designed to support the increasing proliferation of 802.11ac Wave 2 devices such as smartphones, tablets, and high-performance laptops, this access point ensures an optimized user experience. Its Multiuser MIMO capabilities allow it to communicate with multiple clients simultaneously, boosting overall network efficiency and performance in busy environments.
