Wi-Fi Access Point Cisco Aironet 1852E-E-K9C 2.4 GHz 802.11ac Wave 2

The Cisco Aironet 1852E-E-K9C is a controllerless Wi‑Fi access point running Cisco Mobility Express software on the AP. It supports IEEE 802.11ac Wave 2 with a 4x4 radio on 5 GHz and an external antenna, offering up to 1.7 Gbps on the 5 GHz radio and an aggregated dual‑radio throughput of up to 2 Gbps. The access point operates on both 2.4 GHz and 5 GHz bands, supports standard Ethernet LAN rates (10/100/1000 Mbit/s), and uses WPA/WPA2 security. Designed for small and medium-sized deployments, it provides secure, reliable wireless connectivity in a compact white enclosure.

Advantages

The device combines controllerless management (Mobility Express) with Wave 2 performance, simplifying deployment and reducing infrastructure needs. External antennas improve coverage and RF flexibility, while dual‑band operation and Gigabit Ethernet uplinks allow integration into existing networks. Built‑in security support for WPA and WPA2 ensures basic protection for user connections.

Suitable for

• Small and medium-sized business offices
• Retail shops and branch locations
• Classrooms and meeting rooms
• Environments requiring simple, controllerless Wi‑Fi management

When it may not be suitable

This access point is intended for small to mid-size deployments; very large enterprise networks or campus environments that require centralized controllers with advanced policy orchestration may need a controller-based solution. Environments demanding the latest Wi‑Fi features beyond 802.11ac Wave 2 (for example, Wi‑Fi 6/802.11ax) will require newer hardware.

Key specifications

• Wireless standards: IEEE 802.11a/b/g/n/ac (Wave 2)
• Radio configuration: 4x4 on 5 GHz (Wave 2)
• Maximum data rate: up to 1.7 Gbps on 5 GHz; up to 2 Gbps aggregated dual‑radio
• Frequencies: 2.4 GHz and 5 GHz dual‑band
• Ethernet: 2 x RJ‑45 ports, 10/100/1000 Mbit/s
• Security: WPA, WPA2
• External antenna: yes
• Color: white
• Weight: 1.41 kg

How to use

Mount the access point in a central location with good line‑of‑sight to client devices and connect it to the network via the RJ‑45 Ethernet port (supporting PoE if available). Use the embedded Mobility Express setup wizard on the AP to configure SSIDs, security (WPA/WPA2), radio settings and administrative credentials. Monitor performance and make adjustments to channel and power settings as needed through the Mobility Express web interface.

What to consider before purchase

• Network size and whether a controllerless solution meets your management needs
• Compatibility with existing switches and PoE capabilities
• Requirement for external antennas and expected coverage area
• Need for newer Wi‑Fi standards (e.g., Wi‑Fi 6) in the near future

Usage recommendations

Place the Cisco Aironet 1852E access point centrally and at an appropriate height to maximize coverage, enable band‑steering to offload capable clients to 5 GHz, and use the Mobility Express interface for straightforward initial setup and ongoing monitoring.
