Product Overview

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:
  • 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.
  • CleanAir 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.
