Cisco Aironet 1851i Series Wireless Access Point AIR-AP1815I-H-K9
Product Information
The Cisco Aironet 1815i delivers industry-leading wireless performance with support for the latest
Wi-Fi standard, IEEE’s 802.11ac Wave 2 (Figure 1). It also meets the growing requirements of
wireless networks by delivering a better user experience.
The 1815i 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
By adhering to the 802.11ac Wave 2 standard, the 1815i offers a data rate of up to 867 Mbps on the
5-GHz radio. This exceeds the data rates offered by access points that support the 802.11n standard.
It also enables a total aggregate dual-radio data rate of up to 1 Gbps. This provides the necessary
foundation for enterprise and service provider networks to stay ahead of the performance expectations
and needs of their wireless users.
Due to its convenience, in recent years corporate users have increasingly preferred wireless access as
the form of network connectivity. Along with this shift, there is an expectation that wireless should not
slow down users’ day-to-day work, but should enable a high-performance experience while allowing
users to move freely. The 1815i delivers industry-leading performance for highly secure and reliable
wireless connections and provides a robust mobility end-user experience. Table 1 lists the features
and benefits of the 1815i.
Table 1. Features and Benefits
| Feature | Benefit |
| MU-MIMO | Multiuser (MU) 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 2x2:2 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. |
| Cisco Mobility Express solution | Flexible deployment through the Mobility Express solution is ideal for small to medium-sized deployments. Easy setup allows the 1815i to be deployed on networks without a physical controller. |
| Integrated Bluetooth 4.1 | Integrated Bluetooth low-energy (BLE) 4.1 radio for location and asset tracking (future availability). |
