M/A-COM, Inc. is requesting that parts lists, manuals, schematics, block diagrams, tune-up procedure, and operational descriptions for this application not be made routinely available for public inspection. M/A-COM, Inc. considers the information in these exhibits to be classified as trade secrets, pursuant to 47 CFR Section 0.457 and Section 0.459 of the FCC rules. Thank you for your attention to this matter. Daryl Popowitch Regulatory Manager Engineering Project Manager M/A-COM, Inc. – Lynchburg, VA

M/A-COM, Inc. 221 Jefferson Ridge Parkway Lynchburg, VA 24501 Telephone: 434.455.9527 www.macom.com June 8, 2007 M/A-COM, Inc. hereby requests that our grants for OWDTR-0048-E and OWDTR-0050-E list frequencies outside of FCC allocated Part 90 frequencies per FCC 2.807(d). The reason for this request is that M/A-COM, Inc. has United States government and military customers that require use of these frequencies. M/A-COM, Inc. ensures that users other than the United States government and military do not have access to the frequencies outside of the Part 90 allocated frequencies by the following means: Each portable, mobile and base station is configured to specific allocations in our factory prior to shipment to field locations through the use of special and controlled software configuration tools. These software tools are available to M/A-COM and company authorized dealers only. In either case, the requisite rule knowledge and configuration information is available to those configuration personnel.

Ms. Kathy Grzovic Rhein Tech Laboratories, Inc. 360 Herndon Parkway, Suite 1400 Herndon, VA 20170 We certify that we are not subject to denial of federal benefits, that includes FCC benefits, pursuant to Section 5301 of the Anti-Drug Abuse ACT of 1988, U.S.C.862. Further, no party, as defined in 47 CFR 1.2002(b), to the application is subject to denial of federal benefits, that includes FCC benefits.

American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 June 2, 2007 RE: FCC ID: OWDTR-0048-E_ATCB004984 Attention: Kathy Grzovic I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. Please note that the FCC extended frequency band listing requirements state, “Portion of band must not be used solely for a rule part not applied for unless justification in (e), below, applies. Consider splitting rule parts in different line items to remove ambiguity if needed.... For multiple rule part line item, tighter specs must apply where frequency ranges are common between rule parts.” It goes on to say, “The filing must have a justification letter for extended frequencies outside of applied rule part. Operation must be justified under 2.807. For example, Government / Military use or exportation to other countries has been allowed. Justification letter from grantee must indicate marketing plans to ensure USA users, other than those specifically identified, cannot operate device outside bands allowed under the relevant rule parts applied for.” Please note that neither part 90 and part 22 do not appear to have any contiguous operational frequencies between 136 to 150.8MHz. Because the frequency gap from 136MHz to 150.8 is greater than 1/2MHz, this means that the extended frequency band below 150.8MHz cannot be used on an FCC grant for parts 90 or 22. Please revise the 731 form to be in line with the latest FCC extended band listing policy. Alternately, please reference the specific sections of rule parts 90 and 22 that allow operation in the range (136-150.8MHz) mentioned above. Please reference section 2.106 of the FCC rules for specific frequency banding information. 2. Please note that the FCC extended frequency band listing policy for testing states, “Test only on allowed frequencies.” Please note that 143MHz is neither a part 90 nor a part 22 frequency. Please note that in the event justification for the use of 136-150.8MHz can be given, you will still need to retest the device on an actual part 90 and part 22 frequencies. Please retest accordingly. 3. Please note that as of June 2, 2007 RSS119 issue 7 is not a valid test specification. Please retest and/or verify that all testing for Industry Canada is in accordance with the new RSS119 issue 9 specifications. 4. Please note that based on the results of the revised data provided in accordance with the above items, further review comments may be forthcoming. Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination.
