American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 December 19, 2004 RE: FCC ID: STENRPCS10D_ATCB002017 Attention: Jay Kim I have a few comments on this Application. Please note that further comments may arise in response to answers provided to the questions below. 1. As this device has two antenna inputs it is not an amplifier as defined by the FCC. AS this device appears to be more in line with what the FCC calls a booster or repeater operating in the PCS bands it would therefore be a PCB equipment code. Please correct your 731 form to be in line with the accepted FCC rules. 2. Please note that this is a licensed device not subject to part 15 except as a digital device. As such, please explain why the part 15 2-condition statement has been included in the label. 3. Please provide the manual for this device. 4. Please note that for booster and other subclasses of amplifiers it is important that the device reproduce the input faithfully. This means that in order to determine if this is properly being done, the input plots are also required. Please provide all input plots for all signals provided in the report. Please provide input and output for all modulation types used in the booster. 5. Please note that as this device is a subclass of amplifier that operates over a range of frequencies, intermodulation testing is also required. Please provide the necessary intermodulation test data in accordance with FCC rules. 6. Please note that the FCC ID needs to be on the outside of the device. Please provide a location drawing showing the label on the outside, or alternately, please provide evidence that the location of the label is acceptable. 7. Please provide the necessary rf exposure information for this device. Dennis Ward mailto:[email protected] The items indicated above must be submitted before processing can continue on the above referenced application. Failure to provide the requested information may result in application termination. Correspondence should be considered part of the permanent submission and may be viewed from the Internet after a Grant of Equipment Authorization is issued. Please do not respond to this correspondence using the email reply button. In order for your response to be processed expeditiously, you must submit your documents through the AmericanTCB.com website. Also, please note that partial responses increase processing time and should not be submitted. Any questions about the content of this correspondence should be directed to the sender.

Description of EUT 2.1 Summary of Equipment Under Test ♦ FCC ID : STENRPCS10D ♦ Date of Test : 2004.12.07 – 2004.12.14 ♦ Model No. : LGNR 1900CD-10S ♦Freq. Range : - Downlink: 1945 ~ 1950MHz - Uplink: 1865 ~ 1870MHz ♦ Power Rating : AC110V, 50/60Hz ♦ EUT Type : RF Repeater(CDMA), 1900MHz PCS Block D . Report Number: ESTR0412-005 Dates: December 14, 2004 Page 5 of 26 FCC ID: STENRPCS10D EUT Type: RF Repeater (CDMA) 3. DESCRIPTION OF TEST 3.1 RF Power Output - The EUT is a bi-directional amplifier repeater on A-band frequency for broadband PCS. Downlink input (from Base station direction) is connected to a signal generator. Downlink output is connected spectrum analyzer through proper attenuator. The input to the amplifier is set such that the maximum power output is achieved at customer supplied antenna connector. The power measurement method of Uplink is also same way. 3.5 Occupied Bandwidth The signal (Down/Up) input is connected to the signal generator. The input to the amplifier is set such that the maximum power output is achieved at the customer supplied antenna connector (at the antenna connector of base station). Maximum Allowable Downlink Power Output is 40dBm and Maximum Allowable Uplink Power Output is 25dBm. The signal output is connected to the spectrum analyzer. The VBW is set to 3 times the RBW. The sweep time is coupled. 3.6 Spurious and Harmonic Emission at Antenna Terminal The various conducted spurious and harmonic frequencies is measured by means of a calibrated spectrum analyzer. The spectrum is scanned from the lowest frequency generated in the equipment up to 20GHz. Set the RES BW to 1% of the emission bandwidth to show compliance with the -13dBm, limit, in the 1MHz bands immediately outside and adjacent to the top and bottom edges of the frequency block. For the Out-of-Band measurements a 1MHz RBW was used to scan from 30MHz to 10xfo of the fundamental carrier for all frequency block. A display line was placed at -13dBm to show compliance for spurious, and harmonics. Inter-modulation Attenuation Test (3 Signal Method) Blocks Tested: A-F Downlink/Uplink Modulation Tested: Three input signals are chosen such that in the 15MHz channel blocks the lowest and highest channels are selected in addition to the second lowest channel. In the 5MHz channel blocks the lowest and highest channels are selected in addition to the second lowest channel. 3.7 Radiation Spurious and Harmonic Emissions Radiation and harmonic emission are measured outdoors at our 3 meters test range. The equipment under test is placed on a wooden turntable 3 meters from the receive antenna. The receive antenna height and turntable rotations were adjusted for the highest reading on the receive spectrum analyzer. A half wave dipole was substituted in place of the EUT. This dipole antenna was driven by a signal generator with the level of the signal generator being adjusted to obtain the same receive spectrum analyzer reading. This level is recorded. For readings above 1GHz, the above procedure is repeated using horn an…
