FCC Test Report FCC ID: ANOTK1TP10SHR Document Number: FCC 19-0195-0 Prepared by T. Murota Attestation Statements according FCC 15.247 for IBM Bluetooth Daughter Card Registergerichth registered in:Vorstandh Board of Directors:7 layers AG, Borsigstrasse 11 Ratingen HRB 3264Dr. Wolfgang Dahm40880 Ratingen, Germany AufsichtsratsvorsitzendehDr. Hans-Jürgen MeckelburgPhone: +49 (0) 2102 749 0 Chairman of the Supervisory Board:Fax: +49 (0) 2102 749 350 Dr. Sabine Grobeckerwww.7layers.com Annex Additional declaration part according FCC 15.247 for Bluetooth devices Version: 2000-01-11 (Annex - Additional declaration part according FCC 15.247 for Bluetooth devices) Page 2 of 5 pages 1 Output power and channel separation of a Bluetooth device in the different operating modes: The different operating modes (data-mode, acquisition-mode) of a Bluetooth device don’t influence the output power and the channel spacing. There is only one transmitter which is driven by identical input parameters concerning these two parameters. Only a different hopping sequence will be used. For this reason the check of these RF parameters in one op-mode is sufficient. 2 Frequency range of a Bluetooth device: Hereby we declare that the maximum frequency of this device is: 2402 – 2480 MHz. This is according the Bluetooth Core Specification V 1.0B (+ critical errata) for devices which will be operated in the USA. This was checked during the Bluetooth Qualification tests (Test Case: TRM/CA/04-E). Other frequency ranges ( e.g. for Spain, France, Japan) which are allowed according the Core Specification are not supported by this device. 3 Co-ordination of the hopping sequence in data mode to avoid simultaneous occupancy by multiple transmitters: Bluetooth units which want to communicate with other units must be organised in a structure called piconet. This piconet consist of max. 8 Bluetooth units. One unit is the master the other seven are the slaves. The master co-ordinates frequency occupation in this piconet for all units. As the master hop sequence is derived from it’s BD address which is unique for every Bluetooth device, additional masters intending to establish new piconets will always use different hop sequences. 4 Example of a hopping sequence in data mode: Example of a 79 hopping sequence in data mode: 40, 21, 44, 23, 42, 53, 46, 55, 48, 33, 52, 35, 50, 65, 54, 67, 56, 37, 60, 39, 58, 69, 62, 71, 64, 25, 68, 27, 66, 57, 70, 59, 72, 29, 76, 31, 74, 61, 78, 63, 01, 41, 05, 43, 03, 73, 07, 75, 09, 45, 13, 47, 11, 77, 15, 00, 64, 49, 66, 53, 68, 02, 70, 06, 01, 51, 03, 55, 05, 04 (Annex - Additional declaration part according FCC 15.247 for Bluetooth devices) Page 3 of 5 pages 5 Equally average use of frequencies in data mode and behaviour for short transmissions: The generation of the hopping sequence in connection mode depends essentially on two input values: 1. LAP/UAP of the master of the connection 2. Internal master clock The LAP (lower address part) are the 24 LSB’s of the 48 BD_ADDRESS. The BD_ADDRESS is an unambiguous number of every Bluetooth unit. The UAP (upper address part) are the 24 MSB’s of the 48 BD_ADDRESS. The internal clock of a Bluetooth unit is derived from a free running clock which is never adjusted and is never turned off. For synchronisation with other units only offset are used. It has no relation to the time of the day. Its resolution is at least half the RX/TX slot length of 312.5 μs. The clock has a cycle of about one day (23h30). In most case it is implemented as 28 bit counter. For the deriving of the hopping sequence the entire LAP (24 bits), 4 LSB’s (4 bits) (Input 1) and the 27 MSB’s of the clock (Input 2) are used. With this input values different mathematical procedures (permutations, additions, XOR- operations) are performed to generate the sequence. This will be done at the beginning of every new transmission. Regarding short transmissions the Bluetooth system has the following behaviour: The first connection between the two devices is established, a hopping sequence was generated. For transmitting the wanted data the complete hopping sequence was not used. The connection ended. The second connection will be established. A new hopping sequence is generated. Due to the fact that the Bluetooth clock has a different value, because the period between the two transmission is longer (and it cannot be shorter) than the minimum resolution of the clock (312.5 μs). The hopping sequence will always differ from the first one. 6 Receiver input bandwidth and behaviour for repeated single or multiple packets: The input bandwidth of the receiver is 1 MHz. In every connection one Bluetooth device is the master and the other one is the slave. The master determines the hopping sequence (see chapter 5). The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection (e.g. single or multislot packet) is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing according to the packet type of the connection. Also the slave of the connection will use these settings. Repeating of a packet has no influence on the hopping sequence. The hopping sequence generated by the master of the connection will be followed in any case. That means, a repeated packet will not be send on the same frequency, it is send on the next frequency of the hopping sequence. (Annex - Additional declaration part according FCC 15.247 for Bluetooth devices) Page 4 of 5 pages 7 Dwell time in data mode The dwell time of 0.3797s within a 30 second period in data mode is independent from the packet type (packet length). The calculation for a 30 second period is a follows: Dwell time = time slot length * hop rate / number of hopping channels *30s Example for a DH1 packet (with a maximum length of one time slot) Dwell time = 625 μs * 1600 1/s / 79 * 30s = 0.3797s (in a 30s period) For multislot packet the ho…

FCC ID: ANOTK1TP10SHR Document Number: FCC-19-0195-0 IBM Japan Ltd. 1623-14, Shimotsuruma, Yamato-shi Kanagawa-ken 242-8502, Japan August 1, 2002 To whom this may concern OET Requested Information FCC ID : ANOTK1TP10SHR Applicant : International Business Machines Corporation Correspondence Reference Number : 23511 731 Confirmation Number : EA266557 Original Requested Date : July 31, 2002 Subject 1) Can all optional transmitters transmit simultaneously? If no, how is that prevented? If yes, please submit MPE estimation for 2.4 GHz and 5.2 GHz simultaneous. Answer 1) The 2.4GHz PCMCIA option cards transmit simultaneously with the applying device, but the 5.2GHz PCMCIA option card was withdrawn from the application due to the insufficient RF exposure evaluation. Please see the revised exhibit “RF_Exposure_update.pdf” submitted on July/25/2002. Subject 2) Please submit webpage snapshot listing all optional transmitters. Answer 2) The Web page is included in the revised exhibit on July/25/2002. Subject 3) How does this notebook series (slot location and distance to edges, proximity to shielding/metallic structures) compare to laptop used in 5.2 GHz SAR test, and does that SAR test support compliance in the present host? Answer 3) We withdrew the co_location with the 5.2GHz option, so this question is no longer applicable. Subject 4) Source-based time-averaging applies only to fixed transmitters or mobile and portable for occupational use. Please revise RF exposure exhibit accordingly. Subject 5) "Web guidance" for co-located conditions is pending for TCB approval purposes when SAR routine evaluation is needed, and does not apply for this application. Please revise RF exposure exhibit accordingly. Answer 4, 5) Please refer the revised exhibit on July/25/2002. Subject 6) We do not understand the statement: "When the antenna separation from a person's body is closer than 2.5 cm, the near field estimation (i.e. the source- based time- averaging) is not proper method for the RF exposure evaluation. So 5 mW should be considered as the criteria of SAR evaluation for the co-location of transmitters." We think you mean "MPE estimation," not near-field. We think you may intend to apply Suppl C Footnote 14. Please clarify and revise RF exposure exhibit accordingly. Note that if Bluetooth and 5.2 GHz LAN antennas are close together, simultaneous SAR evalution could be needed. Answer 6) The “Web guidance” introduced two evaluation routs for the co-location of standalone transmitters. One is “2% of the source- based time-averaged conducted and radiated output power levels of the dominant transmitter” and the other is “5 mW”. The distance between the PC slot and lap is approximately 1.5cm for all applying PC models, so I thought the former method is not applicable due to near-field. FCC ID: ANOTK1TP10SHR Document Number: FCC-19-0195-0 Anyway we withdrew the 5.2GHz option and revised the RF Exposure evaluation exhibit. We eliminated the “Web guidance” and made a reference to only Suppl C Footnote 14. Please see the revised exhibit on July/25/2002. Subject 7) Please explain how the system uses a BIOS lock or other method, in order to prevent a user from installing unauthorized transmitter modules. Answer 7) The BIOS lock mechanism was basically developed for the customer installation of a mini-PCI type transmitter. But the transmitter modules (both integrated WLAN and Bluetooth) of this applying equipment(ANOTK1TP10SHR) are preinstalled by IBM. Also a broken card will be replaced by IBM ourselves. Therefore there is no phase where an unauthorized transmitter module is installed by a customer in this PC model. Please refer the submittal exhibit “RF_Safety_Info.pdf”. We guide the customers as follows. Subject 8) Page 5 of the DSS test report indicates 32 mW(15dBm) and does not agree with page 19 (100 mW). Please correct. Verify output power. Answer 8) This was a careless miss. The correct specification of the applying transmitter is 20dBm, so we would like to submit an additional page for the replacement in the next page since we can’t revise the test report’s date. Sincerely, August 01, 2002 Shohhei Fujio, Staff Engineer, EMC Engineering, Yamato Laboratory, IBM Japan Ltd. (page 2) i) Installation of the integrated wireless modules The integrated wireless modules (Wireless LAN Mini-PCI Card and Bluetooth card) are preinstalled by IBM, and you are not permitted to install nor replace the integrated modules by yourself.

Murota 2/5 Figure C: Antenna Gain of Bluetooth Daughter Card 2. RF Exposure evaluation of Cisco Aironet Wireless 802.11b The applying equipment is a compact size laptop computer. The built_in antenna for the integrated mini-PCI wireless LAN transmitter is categorized as a mobile device by FCC CFR 47 section 2.1091, because two antenna are located at the same height hence the separation distance between the antennas and the human body is 20cm or more. As shown in the following photos, the applying equipment satisfies the requirement of antenna separation. Antennas are located at the same height The separation distance between the antenna and the human body (lop) is about 21cm . FCC Test Report FCC ID: ANOTK1TP10SHR Document Number: FCC 19-0195-0 Prepared by T. Murota 3/5 The conducted peak output power of the IEEE802.11b Wireless LAN Adapter is 19.9dBm and the maximum antenna gain is 1.42dBi as shown the previous Figure A. Therefore the peak radiated output power(EIRP) is calculated as follows. EIRP = P + G = 19.9 dBm + 1.42 dBi = 21.32 dBm (135.5 mW) Then, the maximum power density at 20cm distance is calculated as : S 1 = EIRP/(4 % R 2 % o) = 0.0270 mW/cm 2 When an operator will use the transmitter during 30 minutes continuously in normal operation, the time-averaging of exposure is : S 1 % 30 = 0.809 < (1mW/cm 2 ) % 30 So the source-based time-averaging duty factor is considered as 100% duty. Therefore the WLAN transmitter meets the MPE requirements for general Population/Uncontrolled exposure. 3. RF Exposure evaluation of Bluetooth transmitters The applying laptop PC (ThinkPad X30 Series) supports three kinds of Bluetooth devices as follows. FCC ID Grantee Name Product Name Granted Date EIRP in FCC test report PI4BT-ULTRA Bluetooth Ultraport Module May/22/2001 1.4 mW User’s option PI4BT-IBM-PCII TDK Systems Europe Ltd. Blutooth PC Card II August/21/2001 1.0mW Applying transmitter ANOTK1TP10SHR IBM Japan, Ltd. Blutooth Daughter Card 2.29mW FCC Test Report FCC ID: ANOTK1TP10SHR Document Number: FCC 19-0195-0 Prepared by T. Murota 4/5 When a customer operates the applying PC on his lap, the sufficient separation distance (min. 20cm) between the antennas of above transmitters and the person’s body (lap) can not be maintained. But the footnote of the Section 3 in Supplement C to OET Bulletin 65 states “ 14 Both conducted and radiated output power should be considered in near-field exposure conditions. The output indicated in the above (500 mW) is appropriate when the device and its antenna are both operating at more than 2.5 – 3.0 cm from a person’s body, such as certain hand-held terminals. If a device, its antenna or other radiating structures are operating at closer than 2.5 cm from a person’s body or in contact with the body, SAR evaluation may be necessary when the output is more than 50 – 100 mW, depending on the device operating configurations and exposure conditions.” Also the latest conditions for co-located transmitters of Web guidance (http://hraunfoss.fcc.gov/ eas_public/LSI_GET/37) states “SAR compliance for co- located transmitters in standalone independently operated product – when SAR evaluation is required for TCB approval, except for the transmitter( s) with the highest output (non- simultaneously transmitting dominant transmitters – AMPS/ TDMA/ CDMA), the output of other co-located transmitters should be less than 2% of the source- based time-averaged conducted and radiated output power levels of the dominant transmitter or 5 mW, whichever is higher.” When the antenna separation from a person’s body is closer than 2.5 cm, the near field estimation, which is used for the calculation of EIRP to estimate the source- based time-averaged MPE limit, is not proper method for the RF exposure evaluation. So 5 mW should be considered as the criteria of SAR evaluation for the co-location of transmitters. The total output power of the three Bluetooth transmitters in the above table is 4.69mW. Therefore those transmitters can co-locate with the dominant transmitter(WLAN) without SAR evaluation. FCC Test Report FCC ID: ANOTK1TP10SHR Document Number: FCC 19-0195-0 Prepared by T. Murota 5/5 4. Other supported PCMCIA cards with SAR compliance The applying equipment supports the following option wireless PCMCIA card plugged in the PC card slot, which complies to the SAR requirement.
