Januar 2006 00:26 Betreff: Response to Inquiry to FCC (Tracking Number 244611) Seite 1 von 1 2006-01-16 Inquiry: Dear Sir/Madam We are a TCB and we have received an application for Certification of a CDMA 2000 PCMCIA data card. The current FCC policy requires a TCB to ask for advice from FCC prior to certifying a CDMA 2000 device. We hereby ask for guidance regarding SAR review procedures. Sincerly EMCC DR. RASEK Klaus Knoerig Response: Thank you for your inquiry - please see attached and below. Investigations by FCC Lab into 3G technologies and SAR measurement systems issues are continuing. Oct05 TCB training notes included the following: - 3G technologies - 1) TCBs must request advice from FCC prior to certifying a device. Preferably a KDB correspondence should be used for this communication. 2) Current advise that we will give for CDMA-2000 and UMTS is: to digest preliminary info documents provided by OET/Lab (CDMA-2000 or WCDMA), then perform reviews of tests to best extent possible. TCBs in their review should apply good engineering judgment and current procedures such as Supplement C to the exten! t applicable. Additional guidance information is under development. Info documents for other technologies have not been developed at present. 3) When unsure how to address a particular point in their review, TCB should again contact OET/Lab for specific advise. 4) Request-for-info correspondence and FCC response should be included as EAS cover-letter exhibit in the filing, to demonstrate that TCB has requested and reviewed info prior to certification. FYI: CDMA-2000 = IS-2000 = 3GPP2 WCDMA = UMTS = 3GPP Do not reply to this message. Please select the Reply to an Inquiry Response link from the OET Inquiry System to add any additional information pertaining to this inquiry.

Januar 2006 00:26 Betreff: Response to Inquiry to FCC (Tracking Number 603426) Seite 1 von 1 2006-01-16 Inquiry: Dear Sir/Madam We are a TCB and we have received an application for Certification of a USB CDMA 2000 data card. The current FCC policy requires a TCB to ask for advice from FCC prior to certifying a CDMA 2000 device. Please find attached external photos and SAR test setup photos. We believe that this device could be used in body-worn configuration for example when connected to a laptop or tablet pc. Do you agree that this device can be certified as a portable device for body-worn use? We hereby ask for guidance regarding SAR review procedures. Sincerely EMCC DR. RASEK Klaus Knoerig Response: Please see response sent to same inquirer today in KDB244611 for overall CDMA-2000 device setup and review info. Exact device normal use configurations are unclear from info at hand. Most USB-connectored small devices are expected to have normal use positions as inserted into laptop computers and used within 20 cm of a person's body, in which case Part 22/24 devices are subject to SAR routine evaluation. FYI note also e.g., from Oct05 TCB training notes: - "Direct-connected" USB (without integral cable) differs from most PCMCIA in that port alignment may be horizontal (H), vertical (V), and 180 degrees H or V, with respect to a notebook computer host - Grantee is responsible for SAR compliance in all such intended use positions - 1-host SAR testing is accepted for many Part 15 and some licensed-service USB-dongle transmitters – 3-host SAR test results have been filed for some licensed-service USB dongles – IDB/KDB Mar04 webpost RFx Procedures 7)b), 7)c) are applicable Do not reply to this message.
