FCC ID: VBNAHDB-01 To Whom It May Concern, Pursuant to FCC 47 CRF 0.457(d) and 0.459, Section 10, Nokia Solutions and Networks requests that a part of the subject FCC and/or IC application listed below be held permanently confidential and permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Operating Description Block Diagram Complete Circuit Diagrams Instruction Book Internal Photographs Parts List Exhibit 5 Exhibit 6 Exhibit 7 Exhibit 8 Exhibit 9 Exhibit 14 Confidentiality of the User Manual is maintained by requiring that any party that is supplied a user manual must first sign a non-disclosure agreement. Currently only cellular system operators have access to these manuals. Internal photos are kept confidential by virtue of the fact that the end product is a non-

consumer product, certified and housed in a sealed enclosure, and is only accessible by trained /approved maintenance personnel. Further, the Applicant has spent substantial effort in developing this product, some aspects of which are deemed to be trade secret and proprietary. Having the subject information easily available to our competitors in this market would negate the advantage we have achieved by developing this product. Not protecting the details of the design will result in financial hardship.
