We, Ericsson AB, hereby request that the Exhibits/Items listed below be withheld from public inspection in accordance with Sections 0.457 and 0.459 of the Commissions Rules. This due to the following reasons:

GSM Base Stations (BS) are designed strictly based on the technical specifications of the international project 3GPP (the 3rd Generation Partnership Project). The competition in this field is very intense and a less advanced solution/design could get an unfair advantage by accessing the information as listed below from common domain. As we believe that we have implemented groundbreaking solutions and designs into our recent BS/Radio Unit (RU) compared to the previous BS/RU, the listed Exhibits/Items need to be protected from disclosure to our competitors in the industry. As the FCC/IC records have in-depth information and a very wide distribution, we believe that you can understand our concerns. We are strong in our belief that all vendors in the industry need to compete by their own merits. We regard these Exhibits/Items to be our intellectual property and therefore as confidential information. As our BS are generally installed in restricted places, public access is not possible thought some types of our BS under certain circumstances can be installed in an unrestricted place, but the doors on all of our BSs are key-locked and can be opened only be by authorized personnel. It is therefore individual modules within our BS that should not be revealed to the public. There are advanced technical and design solutions/information in the Exhibits/Items, as mentioned above, that we regard as Ericsson proprietary, with actual and potential patents pending. The information can be advantageous to our competitors as well as sources seeking ways to hack past the built in security functionality. These solutions or information thereof are not accessible even for our customers or partners unless non-disclosure agreements for particular item(s) have been signed. Confidential product information can be found in, but not necessarily limited to, internal photos of the BS and the RU, block diagrams, schematics diagrams, and parts lists as well as certain documents, such as the users manuals. Those documents can only be accessible by the customers who purchase out BS and accept the conditions and therefore are provided with unique information access tools.

Each party agrees that all confidential documents, work product and information (including all computer code, internal photographs of products, block diagrams, schematic diagrams, technical and/or user manuals, related materials, and the existence of this Agreement) received or otherwise obtained from the other party pursuant to this Agreement, whether before or after the Effective Date, will be, and will be deemed to have been, received in confidence and will be used only for the purpose of carrying out the obligations of, or as otherwise contemplated by, this Agreement. In addition, each party agrees that public access to all confidential equipment supplied will be restricted either by installation of the equipment in a restricted area or by physically securing the equipment by other means, including, but not limited to, using a key-lock that can only be opened by authorized personnel. Without the other partys prior written consent, neither party may disclose any such information to any third party or grant access to the confidential equipment to any unauthorized person, and each party will disclose such information only to such of its officers, employees and agents that have a need to know such information for the purposes contemplated hereby. However, the provisions of this Section will not apply to any such information that (i) is or becomes generally available to the public without the fault or negligence of either party, (ii) is already in the possession of the receiving party without being subject to another confidentiality obligation, (iii) is or becomes available to the receiving party on a non-confidential basis from a source other than the disclosing party; provided that such source is not bound by a confidentiality obligation of the disclosing party, (iv) is required to be disclosed pursuant to an arbitration proceeding conducted in accordance with this Agreement, or (v) is required to be disclosed pursuant to a requirement of any governmental authority or any statute, rule or regulation; provided that the party required to disclose such information of the other party provide to the other party notice of such requirement of any such disclosure and cooperates with the other party to prevent or restrict any such disclosure to the extent allowed by applicable law.

Ericsson AB requests a Grant of Certification (Type Acceptance) for the mentioned FCC Identifier above. This radio base station transceiver has been changed by using a different power transistor in the final transmitter stage. The new transistor has equivalent RF characteristics as the old one. Some matching components around the transistor are also changed. The base station transceiver will in normal mode operate at a nominal power out of 46.3 dBm for GMSK and 43 dBm for 8-PSK at the antenna connector when using combiner unit CDU-G, CDU-J or CDU-K. In TCC mode with two transmitters combined on the same frequency the nominal output power is 49 dBm for GMSK and 45.7 dBm for 8-PSK. The power output is reducible to ~0.3 watts. The transmitter path in CDU-G CDU-J and CDU-K is identical. Due to the too wide frequency spectrum at the band edges the output power has to be reduced in some cases. In both GMSK and 8-PSK mode the output power in channel 128 869.2 MHz and channel251 893.8 MHz has to be reduced to a maximum of 37.9 dBm. Ericsson AB requests confidentiality under CFR 0.459. Confidentiality for the following exhibits is requested:

Exhibit 4 Block diagram Exhibit 5 Part 1 Schematics Exhibit 5 Part 2 Schematics Exhibit 9 Internal photos Exhibit 10 Components and Tune Up Exhibit 12 Circuit description The Radio Base Station (RBS) is always installed and placed in an area with access only to authorize personal. Sensitive information, such as internal photos and manuals is not available for general public in any form. Only customer with a Non-Disclosure Agreement (NDA) in place will get access to sensitive information. So the only way a competitor could get technical information on the RBS is from FCC records. Justification of this request is in order to protect the large investment in developing this technology and to facilitate the circuit miniaturization utilized in this design and protect the innovative design as well as proprietary techniques which are implemented. In order to protect Ericssons competitive advantage on these proprietary techniques, we request the above listed exhibits be held as confidential and withheld from the Public Information File. We further certify that the applicant nor any party to the application is subject to a denial of Federal benefits, that includes FCC benefits, pursuant to section 5301 of the Anti-Drug abuse Act of 1988, 21 U.S.C. Section 862.
