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 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.
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.
Integrated BLE 4.2 radio to enable IoT use cases such as location tracking.
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.
