Overview:

Product Overview

The Cisco Aironet 1840 Access Points delivers an ideal blend of predictable performance in a compact form factor. Packed with 802.11ac Wave 2 features and Bluetooth Low Energy (BLE) for location-based services, this platform is ideal for small to mid-size enterprise deployments.

Ideal for small and medium-sized networks, the Cisco Aironet 1840 delivers industry-leading performance for enterprise and service provider markets via enterprise-class 4x4 MU-MIMO, four-spatial-stream access points that support the Institute of Electrical and Electronic Engineers (IEEE) 802.11ac Wave 2 standard. Integrated BLE radio enables location-based use cases such as wayfinding and asset tracking. The Aironet 1840 Access Point extends support to a new generation of Wi-Fi clients, such as smartphones, tablets, and high-performance laptops that have integrated 802.11ac Wave 1 or Wave 2 support.

Features and Benefits:

802.11ac Wave 1 and 2 capabilities
The IEEE 802.11ac standard delivers a better experience in typical environments, and a more predictable performance for advanced applications such as 4K or 8K video, high-density high-definition collaboration apps, all-wireless offices and Internet-of-Things (IoT).
Multiuser Multiple-Input Multiple-Output (MU-MIMO) technology
Supporting four spatial streams, MU-MIMO enables access points to split spatial streams between client devices, to maximize throughput.
Intelligent Capture
Intelligent Capture probes the network and provides DNA Center with deep analysis. The software can track over 240 anomalies and instantaneously review all packets on demand, emulating the onsite network administrator. Intelligent Capture allows for more informed decisions on your wireless networks.
Cisco Mobility Express
Mobility Express is designed for networks of all sizes, including small and medium-sized businesses and distributed enterprises. It provides industry-leading wireless LAN technology without the need for a physical controller or additional licenses.
Bluetooth 4.2
Integrated BLE 4.2 radio to enable IoT use cases such as location tracking.

Cisco DNA support

Pairing the Aironet 1840 Access Points with the Cisco Digital Network Architecture (DNA) allows for a total network transformation. Cisco DNA allows you to truly understand your network with real-time analytics, quickly detect and contain security threats, and easily provide network-wide consistency through automation and virtualization. By decoupling network functions from the hardware, you can build and manage your entire wired and wireless network from a single user interface.

Working together, the Aironet AP1840 and Cisco DNA offer such features as:

Cisco DNA Spaces
Apple FastLane
Cisco Identity Services Engine
Cisco DNA Analytics and Assurance
And much more

The result? Your network stays relevant, becomes digital-ready, and is the lifeblood of your organization.
