Box 35815 Pittsburgh, PA 15251-3315 Applicant: MIKROTIKLS SIA Pernavas 46 Riga, Latvia LV-1009 Equipment: FCC ID: TV7-CRD FCC Rules: Part 15.247 Gentlemen: The 731 form and application have been electronically submitted and any attachments will be up loaded to your web site to be used in obtaining a grant of certification. Short-term Pursuant to DA 04-1705 of the Commission’s pubic notice, we request short-term confidential treatment for the following information until 45 days after the Grant Date of Equipment Authorization in order to ensure sensitive business information remains confidential until the actual marketing of the device: External Photos File Name CRD ExtPho.pdf Internal Photos File Name CRD IntPho.pdf Test Setup Photos File Name CRD TSup.pdf User Manual File Name CRD UserMan.pdf Permanent MIKROTIKLS SIArequests that the material in the Schematics File Name Conf CRD Schem.pdf Block Diagram File Name Conf CRD BlkDia.pdf Operational Description File Name Conf CRD OpDes.pdf be withheld from public disclosure in accordance with Section 0.459 of the Commissions Rules, 47 C.F.R. 0.459, following grant of the application.

June 25, 2007 Timco Engineering Inc. 849 NW State Road 45 Newberry, FL 32669 Office of Engineering and Technology Federal Communications Commission Columbia, MD 21046 Applicant: MIKROTIKLS SIA Pernavas 46 Riga, Latvia LV-1009 Re: Confidentiality for submittal information regarding FCC ID number TV7-CRD PRODUCT: Broadband wireless internet access point transmitter operating under part 15.247. Dear Sirs: MIKROTIKLS SIA requests that the material in the Schematic, block diagram, and Operational Description be withheld from public disclosure in accordance with Section 0.459 of the Commissions Rules, 47 C.F.R., following grant of the application. In support of this request, MIKROTIKLS SIA submits the following: Long Term Confidential Files Include Schematics File Name Conf CRD Schem.pdf Block Diagram File Name Conf CRD BlkDia.pdf Operational Description File Name Conf CRD OpDes.pdf Short Term Confidential files include External Photos File Name CRD ExtPho.pdf Internal Photos File Name CRD IntPho.pdf Test Setup Photos File Name CRD TSup.pdf User Manual File Name CRD UserMan.pdf 1. Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, block diagram, and Schematics, which are segregated from the non-confidential exhibits of the application, are those for which confidentiality is sought. 2. Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission: The proceeding is that involving the application for equipment authorization (certification) under FCC ID No: TV7- CRD 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 This material includes a detailed theory of operation, circuit diagrams, (schematic diagrams) and any detail Parts List. As such, this material is treated as highly confidential business information. 4. Explanation of the degree to which the information concerns a service that is subject to competition: The material for which confidentiality is sought is employed in the design and manufacture of this transmitting equipment that is offered on a highly competitive basis. Customers for this equipment have a variety of competing sources. 5. Explanation of how disclosure of the information could result in substantial competitive harm: Disclosure would, in effect, give away the fruits of the labors of MIKROTIKLS SIA’s engineering personnel, who have designed the equipment and the manufacturing process. Disclosure would also offer competitors additional unwarranted insight into the state of the product development, thereby allowing competitors an advantage, not available to MIKROTIKLS SIA 6. Identification of any measures taken by the submitting party to prevent unauthorized disclosure: The information for which confidential treatment is sought is kept confidential by MIKROTIKLS SIA and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties: To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of this radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure: This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. This equipment is designed for commercial, industrial, and governmental applications. As such, unlike most consumer equipment, this equipment could be used for more than a decade in some cases. As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers

Subject: Permanent Confidentiality request for FCC ID TV7-CRD To Whom It May Concern, Pursuant to sections 0.457 and 0.459 of CFR 47, the applicant requests permanent confidential treatment of the following information, accompanying this application: Block Diagramms Schematics The above materials contain trade secrets and proprietary information not customarily released to the public.
