Cisco Aironet 1140 Series Access Point

Taking Business Mobility Mainstream

The Cisco® Aironet® 1140 Series Access Point is a business-ready,

802.11n access point designed for simple deployment and energy
efficiency. The high-performance platform, which offers at least six times
the throughput of existing 802.11a/g networks, prepares the business for
the next wave of mobile devices and applications. Building on the Cisco
Aironet heritage of RF excellence, the 1140 Series combines the
industry’s most widely deployed 802.11n technology with a sleek
industrial design that blends seamlessly into any enterprise environment.
Designed for sustainability, the 1140 Series delivers high performance
from standard 802.3af Power over Ethernet while decreasing waste with
multiunit eco-packs and Energy Star certified power supplies. As part of
the Cisco Unified Wireless Network, the 1140 Series provides the
industry’s lowest total cost of ownership and investment protection by
integrating seamlessly with the existing network.

RF Excellence

The Cisco Unified Wireless Network with M-Drive technology removes the
mystery associated with design, implementation, and ongoing
optimization of enterprise wireless networks. With Cisco M-Drive
technology, IT has the tools needed to build and operate a high
performance wireless network without the need for extensive RF
engineering skills. Cisco M-Drive technology is a systemwide approach
that manages the corporate RF spectrum, improves wireless coverage,
and increases system capacity and performance. Features include:

Data Sheet

●

Radio resource management (RRM): Automated self-healing optimizes the unpredictability of RF to reduce
dead spots and help ensure high availability client connections. RRM optimizes network capacity and
mitigates interference by continuously monitoring and adjusting access point power and channel settings and
then load balancing clients to enhance wireless coverage.

Data Sheet

●

CleanAir1 technology: Only Cisco offers a comprehensive solution to detect, classify, locate, and mitigate
sources of interference, including non-Wi-Fi sources such as Bluetooth, microwave ovens, cordless phones,
and more. With the ability to visualize performance-impacting interference directly from Wireless Control
System (WCS), you can proactively manage the challenges of a shared wireless spectrum and optimize
network performance.

Environmentally Responsible

The Cisco Aironet 1140 Series offers 802.11n performance with standard 802.3af Power over Ethernet (PoE). At
only 12.95 watts of power, the 1140 Series is the only platform to combine the power of dual-radio 802.11n with the
efficiency of standard PoE. Additionally, the 1140 Series is designed to operate more efficiently during off-peak
hours when fewer clients are connected to the access point.

For quicker staging and installation, you can order the 1140 Series in multiunit eco-packs, which offer 10 Unified or 5
Standalone access points in a single, easy-to-open carton. Eco-packs reduce product packaging by 50 percent,
preserving natural resources and reducing emissions. By eliminating unnecessary components and offering digital
instead of paper documentation, the 1140 Series eco-packs will save over 2200 trees per year, which is equal to the
amount of power required to heat over 65 homes for an entire year.
