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 4×4 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.
Features and benefits
Feature | Benefit |
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. |
