1 FCC APPLICATION INQUIRY RESPONSE L82-228870: SIEMENS GIGASET 2400 DESK STATION Correspondence Number: 3392 September 17, 1998 1.0 Overview This package was compiled to reply to inquiries made by Mr. Joe Dichoso of the FCC regarding the Type Certification Application for the Siemens Gigaset 2400 Desk Station. Each Inquiry item is listed below followed by the response. 2.0 Inquiry Responses (1) The confidential letter requests only the technical description and the schematic to be held confidential. No technical description was submitted. Two block diagrams were submitted but one was marked confidential and the other was not. Please verify & correct this situation. Answer: A copy of the technical description of the Gigaset 2400 Desk Station is was submitted to the Commission via the ‘add attachments’ option on the electronic filing site on September 17, 1998. The technical description has been revised such that it is no longer Siemens-Confidential. The only portion of this application that should be confidential are the schematics. The correct block diagram was forwarded to the Commission via the ‘add attachments’ option of the electronic filing site on September 17, 1998. (2) The photo of the main board was dark & unfocused. Please submit a clear photo. Answer: Photos of the front & back of the main board were retaken & resubmitted to the Commission via the ‘add attachments’ option on the electronic filing site on September 16, 1998. The main board without the shield was not re-photographed but can be if need. (3) Please show compliance with the 20 dB down requirement at the band edges, when the device is in the highest and lowest channels. Also show compliance with the restricted band requirements (15.205) for the 2483.5 to 2500 MHz restricted band. 2 Answer: Plots of emission bandwidth were taken of the device at the highest and lowest channels and are included in Appendix A of this attachment. A data sheet indicating radiated emission measurements at the low end of the 2483.5 MHz Restricted band are also contained in this Appendix. Based on the measurement procedures contained in Section 15.205 for signals above 1 GHz, the Siemens 2400 Desk Station is compliant with this specification. (4) The 20 dB bandwidth was 903 kHz while the channel separation was only 864 kHz. The channels must be separated by atleast the 20 dB bandwidth. Try using a smaller but appropriate RBW for the 20 dB bandwidth measurement. Answer: The occupied bandwidth was remeasured at bottom, top and middle of the transmit band using a 30 kHz RBW and 100 kHz VBW. Lowering the RBW provides better resolution of the spectrum for a ~700 kHz bandwidth signal. (5) Section 15.247(a)(1) indicates that the system receivers shall have input bandwidths thatn match the hopping channel bandwidths of their corresponding transmitters and shall shift frequencies with the transmitted signals. Please explain how the device complies withthis rule when a packet is repeated or when multiple packets are sent. What is the receiver input bandwidth? How does the receiver shift frequencies and determine which frequencies to shift to in order to synchronize with this transmitter. Answer: The IF bandwidth determines the receiver bandwidth. The IF bandwidth at 3 dB down is 700 kHz. This is equal to the bandwidth of the transmitter. Each base has its own pseudo random hopping sequence. When the mobile is registered with a base, it is given the same hopping sequence and is thus synchronized with that base. Any blocked frequencies are told to the mobile by the base. The phone does not repeat packets, and it does not use multiple packets. Bad packets are dropped. (6) Please provide the calculation method used for RF Output Power. Answer: Calculation of the output power in watts is based on the following formula found in Industry Canada NIR-E document: 3 Power (ERP) = (E * r) / (30) 1/2 Where: E = radiated electric field level in V/m r = distance from the EUT to the measurement antenna The method used in this application to calculate ERP goes through the following steps: (a) Determine the peak level in dBμV/m (b) Translate this level to μV/m using the following formula μV/m = 10^((dbμV/m)/20) (c) Translate this level to V/m by dividing by 1X10 6 (d) Calculate ERP based on the formula at the beginning of this section for a test distance of X meters. (7) How does this device comply with the RF Safety Requirements? Answer: Based on a conversation with Kwok Chan of the Commission on September 16, 1998, the following RF Safety analysis is provided: The power used for evaluation to the RF Safety Hazard Specification can be derated based on the percentage that the transmit signal is actually present over time. For the Gigaset 2400 Desk Station, the duty cycle of the transmit signal over time is 1/8. The Power level used for comparison to the OET-65C limit can be calculated as follows: Ref. Power = (Peak Power) * (Duty Cycle) = (0.469 watts) * ( 1/8) = 0.0586 watts This figure is below the threshold (<0.2 watts at 2450 MHz for cordless phone handsets and most other trasnmitters using monopole or dipole type antennas as an integral part of the device) for this device. The Gigaset 2400 Desk Station uses an integral monopole antenna. Based on this criteria, special warnings or instructions are not required to show compliance for this device. (8) Indicate the manufacturer of the Spread Spectrum Chip. Answer: The manufacturer of the spread spectrum chip is Siemens Semiconductors, Munich, Germanuy. The parts used are a PMB 4729 for the Gigaset 2400 Desk Station and a PMB 4724 for the Gigaset 2400 Handset. 4 (9) The transmitter cannot coordinate its hopping sequence with the hopping sequence of other transmitters, or vice versa, for the purpose of avoiding simultaneous occupancy of individual hopping frequencies by multiple transmitters. Provide a description on how the device complies with this rule. Answer: The hopping frequency sequence is determined by the uni…

1 FCC APPLICATION INQUIRY RESPONSE L82-228870: SIEMENS GIGASET 2400 DESK STATION Correspondence Number: Unknown September 24, 1998 1.0 Overview This package was compiled to reply to inquiries made by Mr. Joe Dichoso of the FCC regarding the Type Certification Application for the Siemens Gigaset 2400 Desk Station. Each Inquiry item is listed below followed by the response. 2.0 Inquiry Responses (1) Based on the bandwidth plot of the device, transmitting on Channel 95, the device is not 20 dB down at the bandedge of 2843.5 MHz. It is only 10 dB down at the bandedge. Also, if the peak radiated field strength of the fundimental is 128 dBuV/m, the peak field strength at the restricted band frequency is 118 dBuv/m, (128-10 = 118 dBuv/m). This is 44 dB above the peak limit of 74 dBuV/m. Please correct/explain. Answer: The original version of Part 15 (Oct 1996) version that we were using showed the limit for this section (15.247(c)) shall be either 20 dB down or meet 15.209, whichever has the least attenuation. The revised (July 1998) version of this document states the 20 dB criteria without a ‘least attenuation’ criteria. The appropriate portions of 15.205 must also be met. Following the last correspondence regarding this application, an inspection of the EUT was made. It was found that the cover of the RF compartment on the device was notsecured properly. This was corrected and the bandedge and occupied bandwidth tests redone. All bandedges are now within the 20 dB criteria. The occupied bandwidth still meets the requirements of the Rules. All of these tests were made with the EUT in fixed freuqency mode. Measurements of the emissions of the EUT in fixed frequency mode set to Channel 95 were made at the base of this restricted band. Measurements were made using average detection criteria in accordance with Section 15.205 (b) of the Rules (measurement above 1 GHz). All emissions in this area were below the 15.205/15.209 limit. Data indicating compliance with the 15.205 restricted band is included with this submission. (2) Redo the output power tests with the EUT in fixed transmit (non-hopping) mode. Perform the ERP calculation based on the following formula: 2 P(EIRP) = {(E * d)^2 } / 30 Answer: Radiated emissions data for Channels 00, 46 and 95 are included with this document. Calculations of ERP based on the corrected formula are included with this data. We request that the Comission correct the 731 data as necessary. For all measurements, the test distance was 1 meter. (3) Re-evaluation the RF Safety issue based on the revised EIRP results. Answer: Based on a conversation with Kwok Chan of the Commission on September 16, 1998, the following RF Safety analysis is provided: The power used for evaluation to the RF Safety Hazard Specification can be derated based on the percentage that the transmit signal is actually present over time. For the Gigaset 2400 Desk Station, the duty cycle of the transmit signal over time is 1/8. The Power level used for comparison to the OET-65C limit can be calculated as follows: Ref. Power = (Peak Power) * (Duty Cycle) = (0.192 watts) * ( 1/8) = 0.024 watts This figure is below the threshold (<0.2 watts at 2450 MHz for cordless phone handsets and most other trasnmitters using monopole or dipole type antennas as an integral part of the device) for this device. The Gigaset 2400 Desk Station uses an integral monopole antenna. Based on this criteria, special warnings or instructions are not required to show compliance for this device. (4) Resend the Photo to the L82-228870 file Answer: Photo was resent on September 24, 1998. 3 APPENDIX EIRP AND RESTICTED BAND DATA 4 Radiated Data Sheet Siemens Business Communication Systems Gigaset 2420HS Desk Station SERIAL #:505MEASUREMENT DISTANCE (m): 1 DATE: Septmber 24, 1998MEASUREMENT HEIGHT: 1 meter PROJECT #: 99-016EUT Orientation: 180 EIRP Freq.ChannelRecordedAntennaCableCorrectedEIRP SettingLevelFactorLossLevel (MHz)(dBuV)(dB/m)(dB)(dBuV/m)(Watts) 2401.00.097.726.81.6126.10.1358 2440.846.098.026.81.6126.40.1455 2483.195.099.226.81.6127.60.1918 Corrected Level = Recorded Level + Antenna Factor + Cable Loss COMMENT #1: All measurements for this test based on peak measurement methods COMMENT #2: TEST ENGINEER:______________________ APPROVED BY: ______________________ John O’BrienJeffery Lenk 5 Radiated Data Sheet Siemens Business Communication Systems Gigaset 2420HS Desk Station SERIAL #:505MEASUREMENT DISTANCE (m): 1 DATE: Septmber 16, 1998MEASUREMENT HEIGHT: 1 meter PROJECT #: 99-016EUT Orientation: 180 RESTRICTED BAND TEST Freq.NotesRecordedAntennaCableCorrectedLimitMargin and LevelFactorLossLevel (MHz)Polarization(dBuV)(dB/m)(dB)(dBuV/m)(dBuV/m)(dB) 2483.5(1) Vertical26.526.81.654.963.5-8.6 2483.5(1) Horizontal26.226.81.654.663.5-8.9 Corrected Level = Recorded Level + Antenna Factor + Cable Loss COMMENT #1: All measurements are average measurements COMMENT #2: Test Distance 1 meter TEST ENGINEER:______________________ APPROVED BY: ______________________ John O’BrienJeffery Lenk 6 Occupied Bandwidth Data Sheet Siemens Business Communication Systems Gigaset 2420HS Desk Station SERIAL #:505PROJECT #: 99-016 DATE: September 24, 1998 COMMENT #1: Channel Setting = 00 COMMENT #2: 20dB Bandwidth = 685 kHz TEST ENGINEER:______________________ APPROVED BY: ______________________ John O’BrienJeffrey Lenk 7 Occupied Bandwidth Data Sheet Siemens Business Communication Systems Gigaset 2420HS Desk Station SERIAL #:505PROJECT #: 99-016 DATE: September 24, 1998 COMMENT #1: Channel Setting = 46 COMMENT #2: 20dB Bandwidth = 683 kHz TEST ENGINEER:______________________ APPROVED BY: ______________________ John O’BrienJeffrey Lenk 8 Occupied Bandwidth Data Sheet Siemens Business Communication Systems Gigaset 2420HS Desk Station SERIAL #:505PROJECT #: 99-016 DATE: September 24, 1998 COMMENT #1: Channel Setting = 95 COMMENT #2: 20dB Bandwidth = 708 kHz TEST ENGINEER:______________________ APPROVED BY: ______________________ John O’BrienJeffrey L…
