Data Sheet

Cisco Aironet 1830 Series Access Points

Product Overview

Ideal for small and medium-sized networks, the Cisco® Aironet® 1830 Series delivers industry-leading wireless
performance with support for the latest Wi-Fi standard, IEEE’s new 802.11ac Wave 2 specification, and meets the
growing requirements of wireless networks by delivering a better user experience. The 1830 Series 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

With 802.11ac Wave 2, the 1830 Series provides a data rate of up to 867 Mbps on the 5-GHz radio, exceeding the
data rates offered by today’s high-end 802.11n access points. It also enables a total aggregate dual-radio data rate
of up to 1 Gbps, providing the necessary foundation for enterprise and service provider networks to stay ahead of
the performance and bandwidth expectations and needs of their wireless users.

Due to its convenience, wireless access is increasingly the preferred form of network connectivity for corporate
users. 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 1830 Series delivers
industry-leading performance for highly secure and reliable wireless connections and provides a robust mobility
experience that includes:

● 802.11ac Wave 2 with 3x3 multiple-input multiple-output (MIMO) technology with two spatial streams when
operating in single-user or multiuser MIMO mode, offering 867-Mbps rates for more capacity and reliability
than competing access points.

● Multiuser MIMO (MU-MIMO) allows transmission of data to multiple 802.11ac Wave 2 capable clients
simultaneously to improve 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.

● Transmit beamforming technology improves downlink performance to mobile devices, including one- and
two-spatial-stream devices on 802.11ac, while improving battery life on mobile devices such as
smartphones and tablets.

● Flexible deployment mode through the Mobility Express Solution is ideal for small to medium-sized
deployments that that require 25 or fewer access points. Easy setup allows the 1830 Series to be deployed
on networks without a physical controller.

All of these features help ensure the best possible end-user experience on the wireless network.
