Open EXHIBIT 13 1 (1) Prepared (also subject responsible if other) No. EAB/RBI/R Per Helmersson Approved Checked Date Rev Reference KI/EAB/RBI/R (P Helmersson) 2003-09-15 B B5KBKRC1311005-1 Federal Communications Commission SP Sveriges Provnings- och ForskningsInstitut Authorization & Evaluation Division Brinellgatan 4 7435 Oakland Mills Road Box 857 Columbia, Maryland 21046 S-501 15 Borås Attention: Equipment Authorization Branch Sweden September 15, 2003 Subject: Certification for FCC ID: B5KBKRC1311005-1 Gentlemen; Ericsson AB requests a Grant of Certification (Type Acceptance) for the above-mentioned FCC Identifier. This base station transceiver is designed for use in the GSM 800 MHz cellular telephone system. The transmitter will operate from 869.4 to 893.6 MHz. The receiver circuit supports 824.4 to 848.6 MHz. The base station operates in the 800 MHz broadband Cellular services as per 47 CFR Part 22 subpart H, 22.901 (d). It meets the requirements of GSM1900 11.10-1 version 4.19.1 specification for operation in GSM cellular systems except for the output frequency range. This base station will in normal mode operate at a nominal power out of 40 watts at the antenna connector. In TCC mode with two transmitters combined on the same frequency is the nominal output power 79 watts. The power output is reducible to ~0.3 watts. The following channels are excluded: Channel 128 – 869.2 MHz and channel 251 – 893.8 MHz. This is because of too wide frequency spectrum at the band edges. This exclusion is done by database settings in the switch software and is a part of the cell planning. Ericsson AB requests confidentiality under CFR 0.459. Confidentiality for the following exhibits is requested: Exhibit 5 CPU Part Schematics Exhibit 5 RF Part Schematics 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 Ericsson’s competitive advantage on these proprietary techniques, we request the above listed exhibits be held as confidential and withheld from the Public Information File. If additional information is needed, please contact me on the below listed number.
