NK73092523Mobile Cellular Transceiver System

1 April 28, 2011 Marlene H. Dortch, Secretary Federal Communications Commission Office of the Secretary 445 12 th Street, S.W. Washington, D.C. 20554 Re: Final Request for Confidentiality of Harris Corporation for FCC ID No. NK73092523 (FCC Correspondence Number 39487) Dear Ms. Dortch: Harris Corporation (“Harris”) submits this revised, post grant request for confidentiality. Public disclosure of certain materials included in the above referenced equipment authorization application could reasonably put public safety officials at risk, jeopardize the integrity and value of investigative techniques and procedures, reveal Harris trade secrets due to the nature of the equipment, and harm Harris’ competitive interests. Harris respectfully requests, pursuant to 47 C.F.R. § 0.457(g), 47 C.F.R. § 0.457(d), and 47 C.F.R. § 0.459, that certain documents be held as confidential and withheld from public inspection or be superseded in the Commission’s equipment authorization system by subsequently filed versions. Exhibit A, Exhibit B, and Exhibit C provides listings of Harris’ requested treatment of exhibits, cover letters and correspondence. Exhibit A- Harris respectfully requests that these documents be treated as confidential and withheld from public inspection. Exhibit B- Harris respectfully requests that these documents be superseded in the Commission’s equipment authorization system because the materials have been subsequently replaced with a revised version. Exhibit C- The following documents may be made publicly available without any restrictions. 1. Confidentiality Compliance with 47 C.F.R. § 0.457(g) Section 0.457(g)(5) and (6) of the Commission’s rules—pursuant to 5 U.S.C. § 552(b)(7)(E) and (F)—provides confidentiality if the production of records would either “disclose law enforcement investigative techniques or procedures,” or “endanger the life or physical safety of public law enforcement.” The product FCC ID No. NK73092523 is intended for use by federal, state, and local public safety entities. The nature of the product make it necessary for the descriptions provided in the equipment authorization application and supporting documents/exhibits— including technical information regarding the performance parameters, design and operation of the technology, and information regarding the identity of the entities proposing to use the product—be withheld from public disclosure and treated as H A R R I S C O R P O R A T I O N 600 Maryland Avenue, S.W. Suite 850E Washington, D.C. 20024 phone 1-202-729-3700 fax 1-202-729-3735 www.harris.com 2 confidential under Section 0.457(g) of the Commission's rules. A complete list of documents that Harris respectfully requests be treated as confidential and withheld from public inspection is provided in Exhibit A. To further support Harris’ request for confidentiality and to underscore the need for confidentiality, Harris requests that the Commission condition its equipment authorization application as stated below: Requested Equipment Authorization Conditions: (1) The marketing and sale of these devices shall be limited to federal/state/local public safety and law enforcement officials only; and (2) State and local law enforcement agencies must advance coordinate with the FBI the acquisition and use of the equipment authorized under this authorization. These conditions are respectfully requested to ensure that the product associated with FCC ID No. NK73092523 is limited to its intended use, operated only by federal, state, and local public safety officials, and to prevent and address concerns regarding the proliferation of the equipment to unauthorized users. Providing confidential treatment of the materials included with the equipment authorization application identified as FCC ID No. NK73092523 would be in compliance with Section 0.457(g) of the Commission’s rules—specifically 47 C.F.R. § 0.457(g)(5) and (6). It is crucial to the protection of public safety officials that all materials identified in Exhibit A be treated as confidential and withheld from public inspection. 2. Confidentiality Compliance with 47 C.F.R. § 0.457(d). Likewise, Section 0.457(d) of the Commission’s rules provides that trade secrets may not be routinely made available for public inspection. Harris competes with a number of companies that are developing and marketing similar public safety devices. Harris is careful in protecting proprietary aspects of its equipment design and manufacturing processes due to the sensitive nature of the product. The information for which confidential treatment is sought has been kept confidential from public disclosure by Harris and has not been made available to third parties without the execution of non-disclosure agreements. Disclosure of the technical information disclosed in the attached documents to competitors could compromise Harris' ability to develop and protect this technology as other companies could reverse engineer products using the information provided as part of the equipment authorization application. Moreover, disclosure of technical content would relinquish valuable proprietary information about the technologies Harris has developed and its manufacturing processes. Disclosure would also offer competitors additional unwarranted insight into the state of Harris' product development, thereby allowing competitors an advantage that would otherwise be unavailable to Harris. Therefore, in furtherance of Section 0.457(d) of the Commission’s rules, Harris respectfully requests that all materials identified in Exhibit A be treated as confidential and withheld from public inspection. 3 3. Confidentiality Compliance with 47 C.F.R. § 0.459(b). Pursuant to Section 0.459(b)(1-9) of the Commission's rules, Harris provides the following information in support of its request for confidentiality: (1) The information disclosed in the attached equipment authorization application includes highly confidential and proprietary technical information about …
