Cisco 1000 Series lightweight access points come equipped with internal radios and sectorized antennas, with the 1020 and 1030 models supporting RP-TNC connectors to connect optional external antennas. These multimode 802.11 a/b/g access points provide maximum deployment flexibility and investment protection. In addition, all models are UL 2043 rated to accommodate nearly all building deployment scenarios, such as installation in plenum air spaces. These devices support IEEE 802.3af Power over Ethernet (PoE) and auto MDI/MDIX, and offer standards-based, over the air quality of service (QoS), providing additional deployment flexibility. Using the Lightweight Access Point Protocol (LWAPP), Cisco lightweight access points can automatically detect the best available Cisco wireless LAN controller and download appropriate policies and configuration information with no hands-on intervention.
