Cisco Aironet 1840 Series Access Point

Product Overview

Ideal for small and medium-sized networks, the Cisco® Aironet® 1840 Series 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 1840 Series t 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. 

With the 1840 Series, you can secure remote workers or the micro-office. Any Cisco Aironet or Catalyst access point can function as an OfficeExtend access point (OEAP). With an OEAP, an employee at home or in a temporary micro-office will have access to the corporate SSID and the corporate network without the need to set up a VPN or have any advanced technical know-how. 

Cisco User Defined Network, a feature available in Cisco DNA Center, allows IT to give end users control of their very own wireless network partition on a shared network. End users can then remotely and securely deploy their devices on this network. Perfect for university dormitories or extended hospital stays, Cisco User Defined Network grants both device security and control, allowing each user to choose who can connect to their network. (Available second half of calendar year 2020.) 

The Wi-Fi 6 readiness dashboard is a new dashboard in the Assurance menu of Cisco DNA Center. It will look through the inventory of all devices on the network and verify device, software, and client compatibility with the new Wi-Fi 6 standard. After upgrading, advanced wireless analytics will indicate performance and capacity gains as a result of the Wi-Fi 6 deployment. This is an incredible tool that will help your team define where and how the wireless network should be upgraded. It will also give you insights into the access point distribution by protocol (802.11 ac/n/abg), wireless airtime efficiency by protocol, and granular performance metrics. 

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. 

* Available in a future release.

Cisco DNA support

Pairing the 1840 Series Access Points with Cisco 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 1840 Series and Cisco DNA offer such features as:  

• Cisco DNA Spaces  
• Fast Lane  
• 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.
