NE3PCS010850MHz FLEXCU AND FDUAMCO

s FCC ID: NE3PCS010 March 7, 2005 TIMCO Engineering 849 NW State Road 45 Newberry, Florida 32669 RE: Confidentiality Request for FCC ID: NE3PCS010 Dear Sir or Madam, In accordance with Section 0.459 of the commission rules, Siemens ICM, LLC requests confidentiality for the following Exhibit Types: Operational Description, Parts List/Tune-up Info, Schematics, Block Diagrams, User Manuals, and Internal Photographs. This request is based on the following reasons: Siemens serves a market both new and technically very advanced. Hence competition among equipment providers is very high, with millions of dollars at stake. Siemens’ applications for certification contain technical information regarding technology it spent millions of dollars to develop. If classified as non- confidential, Siemens’ competitors would gain an unfair advantage at Siemens’ expense. User Manuals are not available to the general public in any form. User Manuals are sellable items, made available only to legitimate Siemens customers (mobile telephone operators who own FCC licenses for the appropriate frequency bands). It is Siemens’ policy to provide User Manuals to a third party only upon execution of a Mutual Non-Disclosure Agreement (“NDA”). Siemens base stations are normally installed in a restricted area, accessible only by Siemens or its customer. When not installed in a restricted area, such as a rooftop, Siemens base stations are always locked with temper-proof hardware and locks, again accessible only by Siemens and its customer. Accordingly, only authorized persons, who also previously signed an NDA, have access to the inside of a Siemens base station cabinet. By not classifying User Manuals and Internal Photographs as confidential, the FCC allows Siemens’ competitors (or anyone else) to access to Siemens’ confidential and proprietary information via the FCC’s web site. This would cause irreparable damage to Siemens and place Siemens at a competitive disadvantage. For these reasons, Siemens strongly requests confidentiality for the following Exhibit Types: Operational Description, Parts List/Tune-up Info, Schematics, Block Diagrams, User Manuals, and Internal Photographs.

Module Name Siemens Part No. Serial No. Test No. FCU850V1 S30861-U2409-X-04/01 UEB/SN216141 1, 2, 3, 4, 7 FDUAMCO850V2 (in 2:2 mode) S30861-U2413-X-04/01 RMX/S3000013 1, 2, 3, 4, 7 FCU850V1 S30861-U2409-X-04/01 UEB/SN216150 5 FCU850V1 S30861-U2409-X-04/01 UEB/SN216141 5 FDUAMCO850V2 (in 4:2 mode) S30861-U2413-X-05/01 RMX/S9600181 5 FCU850V1 S30861-U2409-X-04/01 UEB/SN216150 6 FCU850V1 S30861-U2409-X-04/01 UEB/SN216141 6 FDUAMCO850V2 (in 4:2 mode) S30861-U2413-X-05/01 RMX/S9600181 6 For a functional description of the modules, please refer to the appropriate related parts and exhibit sections of this certification application. The tests were conducted with the modules installed in a BS-240XLU II. Worst-case measurement data is reported. To comply with the FCC rules (§2.1051, §22.917), the maximum transmit power at the antenna port of channel numbers 128 (869.2 MHz) and 251 (893.8 MHz) is decreased according to the following table. Type of ECU Carrier Frequency [MHz] Channel No. Maximum RF power output GMSK Maximum RF power output 8PSK FCU850V1 869.2 128 38.8 dBm = 7.6 W 41.8 dBm = 15.1 W FCU850V1 893.8 251 38.2 dBm = 6.6 W 41.5 dBm = 14.1 W A complete description of the transceiver’s calibration/tuning procedure is included in the Parts List and TuneUp exhibit section of this application. FCC ID:NE3PCS010 NE3PCS010_FDUAMCO850V2_FCU850V1.doc Page 5/63 09/02/2005 2 Measurements 2.1 General description 2.1.1 EUT configuration and operating conditions If not stated otherwise, the following standard setup procedure for the EUT under test was used: A BSC simulator is used to control the EUT and is connected to the EUT via the A bis Link. For detailed test system equipment configuration please refer to Fig.1 on page 6. The transmitter modules were tuned up according to the procedure described in the TuneUp exhibit section of this application. During the measurements, one carrier channel was tested at a time. The carrier was set to the maximum power level with all timeslots activated to ensure the maximum emission amplitudes during all measurements. A pseudo random bit pattern was applied to the digital modulator. This ensures that the measurements of the emission characteristics of the transmitter are pursuant to § 2.1049. 2.1.2 Selected carrier test frequencies The measurements were performed at 3 selected carrier test frequencies, according to the following table: Carrier Test Frequency [MHz] Remark 869.2 lowest possible carrier frequency 881.6 frequency at the middle of the band 893.8 highest possible carrier frequency 2.1.3 Modulation characteristics The EUT supports two types of modulation: GMSK and 8PSK. The modulation characteristic of the GMSK and the 8PSK modulation is defined in standard 3GPP TS 05.04. During all measurements described below, a pseudo random sequence was applied to the digital modulator to ensure that the emission characteristics of the transmitter are pursuant to § 2.1049. FCC ID:NE3PCS010 NE3PCS010_FDUAMCO850V2_FCU850V1.doc Page 6/63 09/02/2005 2.1.4 Measurement test configuration If not stated otherwise, the following measurement configuration was used to perform all measurements (see figure below): Freq. Stand. Abis GPIB FSIQ BTS 30 dB HF Test PC, BSC-Sim Fig. 1 – Measurement Test Configuration The EUT is controlled by a BSC simulator via the serial A bis Link. The RF output signal is connected to a spectrum analyzer (FSIQ26, Rohde&Schwarz) via a high power 30 dB attenuator. The attenuator is used to protect the input of the spectrum analyzer from high RF power levels. A description of the analyzer …
