The Cisco® Aironet® 1140 Series Access Point is a business-ready, indoor access point designed for simple deployment and energy efficiency. The 1140 Series is a dual-band, 802.11n access point with integrated antennas. It can be ordered in a controller-based* (lightweight) or Standalone (autonomous) version. It may also be ordered with a single-band 802.11g/n (2.4-GHz) radio for use in regulatory domains that do not allow 802.11a (5-GHz) operation.
*The Cisco Unified Wireless Network supports two architectural options - standalone and controller-based. The standalone solution does not require controllers and is ideal for small scale or distributed deployments. The controller-based option is recommended for businesses of any size and deployment topology. It is the most scalable solution and delivers the greatest flexibility and feature velocity for distributed or centralized deployments.
