Ericsson Internal EXHIBIT 13 1 (2) Prepared (also subject responsible if other) No. EJIAXIA TA8AKRC161436-1 Approved Checked Date Rev Reference CBC/XRV/D Xiaoying Jiang 2015-01-28 A Federal Communications Commission Authorization & Evaluation Division 7435 Oakland Mills Road Columbia, Maryland 21046 Attention: Equipment Authorization Branch TUV SUD BABT Octagon House, Concorde Way Fareham, Hampshire, PO15 5RL United Kingdom January 28, 2015 Subject: Request for Confidentiality To Whom It May Concern: 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 Commission’s Rules. This due to the following reasons: Ericsson 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)/Radio Dot (RD) compared to the previous BS/RU/RD, the listed Exhibits/Items need to be protected from disclosure to our competitors in the industry. As the FCC 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. 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, RU and the RD, block diagrams, schematics diagrams, and parts lists as well as certain documents, such as the user’s manuals. Those documents can only be accessible by the customers who purchase our BS/RU/RD and accept the conditions and therefore are provided with unique information access tools.

Ericsson Internal EXHIBIT 13 1 (1) Prepared (also subject responsible if other) No. EJIAXIA TA8AKRC161436-1 Approved Checked Date Rev Reference CBC/XRV/D Xiaoying Jiang 2015-01-28 A Federal Communications Commission Authorization & Evaluation Division 7435 Oakland Mills Road Columbia, Maryland 21046 Attention: Equipment Authorization Branch TUV SUD BABT Octagon House, Concorde Way Fareham, Hampshire, PO15 5RL United Kingdom January 28, 2015 Subject: Certification for FCC ID: TA8AKRC161436-1 To Whom It May Concern: Ericsson AB requests a Grant of Certification (Type Acceptance) for the above mentioned FCC Identifier. This base station transceiver (Remote Radio Unit – RRUS 82 B41) is designed for use in LTE mobile telephone system. The transmitter and receiver will operate from 2496 MHz to 2690 MHz. It supports Channel Bandwidth of 20 MHz. This base station transceiver (RRU) supports modulation type QPSK, 16QAM and 64QAM. This base station transceiver (RRU) is appropriate to use in different Ericsson radio base stations without re-measurement and re-filing when introducing a new base station type. The base station transceiver (RRU) operates in the Broadband Radio Service and Educational Broadband Service band as per 47 CFR Part 27 subpart M. It meets the requirements of 3GPP specification for operation in LTE cellular systems. This base station transceiver (RRUS 82 B41) will in normal mode operates at a nominal power out of 10 and 20 watts at each of the output connector. The Exhibit 8 user manuals submitted with this application is generic and may cover multiple products. This application is only valid for the model specified in the Exhibit 12 circuit description. Ericsson AB requests confidentiality under CFR 0.459 according to attached letter. 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. If additional information is needed, please contact me on the below listed number.
