Data Sheet
Cisco Aironet 1815i Access Point
Ideal for small and medium-sized networks, the Cisco® Aironet® 1815i Access Point
brings a full slate of Cisco high-performance functionality to the enterprise
environment.
Product Overview
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 highperformance 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-today 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.

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).

Prominent Features
Increased wireless performance
The 1815i access point supports the latest 802.11ac Wave 2 standard for higher performance, greater access, and
higher-density networks. With simultaneous dual radios and dual band with 802.11ac Wave 2 MU-MIMO
functionality, this access point can handle the increasing number of high-bandwidth devices that will soon become
a common part of the network.
Wired access
The 1815i allows wired access via a single RJ-45 10/100/1000 auto-detection port. It supports full operation modes
using PoE 802.3af power.
Mounting
These sleek access points with a small form factor are designed with flexible mounting options in mind. You can
mount them directly on the ceiling or a wall. They are also easy to install.
