Console | • Micro USB console (Type A).• RJ45. |
Micro-USB port (reserved) | • Micro-USB port to support remote LTE diagnostics and monitoring tools (Qualcomm CAIT and Spirent UDM) (USB 3.0). |
WLAN interfaces |  Multiuser Multiple-Input Multiple-Output (MU-MIMO) allows transmission of data to multiple 802.11ac Wave 2–capable clients simultaneously to improve the client experience. Prior to MU-MIMO, 802.11n and 802.11ac Wave 1 access points could transmit data to only one client at a time, typically referred to as Single-User MIMO (SU-MIMO).
802.11ac Wave 2 with 2Ă—2:2 MIMO technology uses two spatial streams when operating in SU-MIMO or MU-MIMO mode, offering 867-Mbps rates for more capacity and reliability than competing access points. Flexible deployment through the Mobility Express solution is ideal for small to medium-sized deployments. Easy setup allows the 1000 Series (similar to 1815i) to be deployed on networks without a physical controller. For more information, view the Cisco Aironet 1815i Access Point Data Sheet. |
