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.

Response to Questions Posed by Mr. Andrew Leimer, FCC Application Processing Branch July 6, 2005 Re: FCC ID: LDK102056 Applicant: Cisco Systems, Inc. Correspondence Reference Number 29134 731 Confirmation Numbers EA458806 and EA88290 1) Submit an internal photos exhibit. You can cut/paste them from the external photos exhibit. A file is required or the system will lock out the Grant feature. An internal photos exhibit has been uploaded. 2) Explain how this device meets the unique antenna connector requirements of Section 15.203. This device uses reverse polarity TNC connectors for external antenna connections to comply with the unique antenna connector requirement of 15.203. 3) Submit a new Theory of Hardware Operation file. Figure 1 is unreadable. Please view the file before resubmission. A new Hardware Theory of Operation has been uploaded. 3) Submit an MPE exhibit the RF Exposure exhibit. Once again, you can cut/paste it from the Test Report exhibit. An RF exposure exhibit has been uploaded. 4) “Submit a letter explaining how this device meets the definition and requirements for SDR.” 47 U.S.C. Section 2.1 Terms and Definitions. * * * * * (c) * * * Software Defined Radio. A radio that includes a transmitter in which the operating parameters of frequency range, modulation type or maximum output power (either radiated or conducted), or the circumstances under which the transmitter operates in accordance with Commission rules, can be altered by making a change in software without making any changes to hardware components that affect the radio frequency emissions. The hardware and firmware architecture allows alteration of the frequency range and output power in a conducted sense under software control. The “circumstances under which the transmitter operates in accordance with Commission rules,” in particular, will apply to future software releases enacting approved DFS operation in the 5.47-5.725 GHz band. This and any other future operational changes will be implemented completely in software without any hardware component changes “that affect the radio frequency emissions.” The access point has been designed and characterized in advance for compliant operation in the 5.47-5.725 GHz band. Said operation will be made available to customers by Cisco’s future release and controlled distribution of software updates under the allowance of a Class III permissive change. 2.944 Software Defined radios. (a) Manufacturers must take steps to ensure that only software that has been approved with a software defined radio can be loaded into the radio. The software must not allow the user to operate the transmitter with operating frequencies, output power, modulation types or other radio frequency parameters outside those that were approved. Manufacturers may use means including, but not limited to the use of a private network that allows only authenticated users to download software, electronic signatures in software or coding in hardware that is decoded by software to verify that new software can be legally loaded into a device to meet these requirements and must describe the methods in their application for equipment authorization. Future software releases which allow new operational parameters, particularly approved operation in the 5.47-5.725 GHz band, will be released in a conventional manner to Cisco customers. New units shipping from the factory, as well as units already in the field, have unalterable firmware configurations which define the radio’s regulatory domain. These configurations will interact with the new software to restrain the operation within the original regulatory domain. (b) Any radio in which the software is designed or expected to be modified by a party other than the manufacturer and would affect the operating parameters of frequency range, modulation type or maximum output power (either radiated or conducted), or the circumstances under which the transmitter operates in accordance with Commission rules, must comply with the requirements in paragraph (a) of this section and must be certified as a software defined radio. Cisco neither has provided for or expects any third party alteration of software. This includes software installed on existing units as well as future software updates. (b) Applications for certification of software defined radios must include a high level operational description or flow diagram of the software that controls the radio frequency operating parameters. Such descriptions and diagrams are attached to the original filing. See attachments Cisco AP Software Theory of Operation. 2.1043 Changes to certificated equipment. * * * * * (b) * * * (3) A Class III permissive change includes modifications to the software of a software defined radio transmitter that change the frequency range, modulation type or maximum output power (either radiated or conducted) outside the parameters previously approved, or that change the circumstances under which the transmitter operates in accordance with Commission rules. When a Class III permissive change is made, the grantee shall supply the Commission with a description of the changes and test results showing that the equipment complies with the applicable rules with the new software loaded, including compliance with the applicable RF exposure requirements. The modified software shall not be loaded into the equipment, and the equipment shall not be marketed with the modified software under the existing grant of certification, prior to acknowledgement by the Commission that the change is acceptable. Class III changes are permitted only for equipment in which no Class II changes have been made from the originally approved device. NOTE TO PARAGRAPH (b)(3): Any software change that degrades spurious and out-of-band emissions previously reported to the Commission at the time of initial certification would be considered a change in frequency or modulation and would require a Class III permissive change or new equipment autho…
