s FCC ID: NE3PCS101 February 7, 2006 TIMCO Engineering 849 NW State Road 45 Newberry, Florida 32669 RE: Confidentiality Request for FCC ID: NE3PCS101 Dear Sir or Madam, In accordance with Section 0.459 of the commission rules, Siemens ICM, LLC requests confidentiality for the following Exhibit Types: Operational Description, Parts List/Tune-up Info, Schematics, Block Diagrams, User Manuals, and Internal Photographs. This request is based on the following reasons: Siemens serves a market both new and technically very advanced. Hence competition among equipment providers is very high, with millions of dollars at stake. Siemens’ applications for certification contain technical information regarding technology it spent millions of dollars to develop. If classified as non- confidential, Siemens’ competitors would gain an unfair advantage at Siemens’ expense. User Manuals are not available to the general public in any form. User Manuals are sellable items, made available only to legitimate Siemens customers (mobile telephone operators who own FCC licenses for the appropriate frequency bands). It is Siemens’ policy to provide User Manuals to a third party only upon execution of a Mutual Non-Disclosure Agreement (“NDA”). Siemens base stations are normally installed in a restricted area, accessible only by Siemens or its customer. When not installed in a restricted area, such as a rooftop, Siemens base stations are always locked with temper-proof hardware and locks, again accessible only by Siemens and its customer. Accordingly, only authorized persons, who also previously signed an NDA, have access to the inside of a Siemens base station cabinet. By not classifying User Manuals and Internal Photographs as confidential, the FCC allows Siemens’ competitors (or anyone else) to access to Siemens’ confidential and proprietary information via the FCC’s web site. This would cause irreparable damage to Siemens and place Siemens at a competitive disadvantage. For these reasons, Siemens strongly requests confidentiality for the following Exhibit Types: Operational Description, Parts List/Tune-up Info, Schematics, Block Diagrams, User Manuals, and Internal Photographs.
