ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS. THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY. The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense. The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense. You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: • Turn the television or radio antenna until the interference stops. • Move the equipment to one side or the other of the television or radio. • Move the equipment farther away from the television or radio. • Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.) Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.

In this mode, DFS is supported as well as the channels in the 5470-5725MHz band. Mode 2 Running in managed “Light Weight Access Point Protocol (LWAPP)” mode, where a group of access points are managed by a central switch. In this mode, DFS is not supported at this time, and the channels in the 5470-5725MHz band are disabled. Both DFS and the 5470-5725MHz band will be supported in this mode by the July, 2007 deadline. In both modes, the DFS mechanism is controlled in the access point's IOS software image. Best Regards, Jim Nicholson EMC Compliance Engineer

Page 1 of 4 AIR-AP1131AG Antenna System Design Specification 1. Introduction The AIR-AP1131AG access point is a dual band, simultaneous AP supporting 802.11b and 802.11g in the 2.4 GHz band and 802.11a in all the available 5 GHz bands. As such, the product contains a total of 4 antennas. There are two antennas for the 2.4 GHz band and two antennas for the 5 GHz band. The design and operation of these antennas is covered in this document. 3. Antenna Design An inverted-F antenna will be used for both bands. This antenna type is shown in the Figure 1 below. It is formed by bending a monopole antenna down over a ground plane and then driving the resultant antenna away from the grounded end to achieve a 50 Ω driving point impedance. Typically, these antennas are built using a flat plate, rather than a wire, for VSWR bandwidth considerations. 9/08/2004 AIR-AP1131AG Antenna System Design Specification A printed version of this document is an uncontrolled copy.
