THIS MUST BE SIGNED BY THE APPLICANT/AGENT AND SHOULD BE PLACED ON APPROPRIATE LETTERHEAD Request for Confidentiality Date: 2012-3-12 Subject: Confidentiality Request for: _ AZYHF-A11X Pursuant to FCC 47 CRF 0.457(d) and 0.459 and IC RSP-100, Section 10, the applicant requests that a part of the subject FCC application be held confidential. Type of Confidentiality Requested Exhibit Short Term Permanent Block Diagrams Short Term External Photos Short Term Permanent* 1 Internal Photos Short Term Permanent Operation Description/Theory of Operation Short Term Permanent Parts List & Placement/BOM Short Term Permanent Tune-Up Procedure Short Term Permanent Schematics Short Term Test Setup Photos Short Term Permanent* User’s Manual *Note: ______(Insert Explanation as Necessary)______ ______ Hi-flying Electronics Technology Co.,Ltd.______ has spent substantial effort in developing this product and it is one of the first of its kind in industry. Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confidentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of ___(specify number of days not to exceed 180 ) 2 ___ days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705. NOTE for Industry Canada Applications: The applicant understands that until such time that IC distinguishes between Short Term and Permanent Confidentiality, either type of marked exhibit above will simply be marked Confidential when submitted to IC. Sincerely, By: __ ________________________ ________ SEN XIE ________________ 1 - The asterisked items (*) require further justification before permanent confidentiality will be allowed. These also currently require review by the FCC under their Permit-But-Ask policy before the grant is issued and can delay completion of an application. Further justification should be added to the note above. One such example for a potted device would be: “The EUT is FULLY potted using a non-removable epoxy based material. Removal of potting material causes irreparable damage to internal circuitry. See photographs exhibits that outline the device before and after potting.” 2 - Please refer to http://acbcert.com/documents/misc-docs/Memo-Short-Term-Vs-Standard-Confidentiality.pdf for complete details.

Test Report Report No.:RZA1202-0233MPE01 Page 2 of 6 Maximum Permissible Exposure Type of EUT: Embedded WiFi module FCC ID: AZYHF-A11X Manufacturer: Hi-flying Electronics Technology Co.,Ltd. Model: HF-A11x Maximum conducted output power (measured) and antenna Gain: According to section 1.1310 of FCC 47 CFR Part 1, limits for maximum permissible exposure (MPE) are as following Band Maximum average conducted output power (dBm) Antenna Gain (dBi) 802.11b 15.65 0.8 802.11g 11.98 0.8 802.11n HT20 11.84 0.8 802.11n HT40 12.25 0.8 TA Technology (Shanghai)Co.,Ltd. Test Report Report No.:RZA1202-0233MPE01 Page 3 of 6 Note1. Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. Limits for occupational/controlled exposure also apply in situations when an individual is transient through a location where occupational / controlled limits apply provided he or she is made aware of the potential for exposure. Note2: General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure. TA Technology (Shanghai)Co.,Ltd. Test Report Report No.:RZA1202-0233MPE01 Page 4 of 6 The maximum permissible exposure for 1500~100000MHz is 1.0. So IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. No change to the antenna or the device is permitted. Any change to the antenna or the device could result in the device exceeding the RF exposure requirements and void user’s authority to operate the device. Band The maximum permissible exposure 802.11b 1.0 mW/cm² 802.11g 1.0 mW/cm² 802.11n HT20 1.0 mW/cm² 802.11n HT40 1.0 mW/cm² TA Technology (Shanghai)Co.,Ltd. Test Report Report No.:RZA1202-0233MPE01 Page 5 of 6 RF Exposure Calculations: The following information provides the minimum separation distance for the highest gain antenna provided. This calculation is based on the conducted power, considering maximum power and antenna gain. The formula shown in OET Bulletin 65 is used in the calculation. Equation from OET Bulletin 65, Edition 97-01 is: S= PG / 4∏R 2 where: S = power density (in appropriate units, e.g. mW/cm 2 ) P = power input to the antenna (in appropriate units, e.g., mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (appropriate units, e.g., cm) 802.11b: PG = 15.65dBm+(0.8dBi)=16.45dBm=44 mW 802.11g PG = 11.98dBm+(0.8dBi)=12.78dBm=19 mW 802.11n HT20 PG = 11.84dBm+(0.8dBi)=12.64dBm=18 mW 802.11n HT40 PG = 12.25dBm+(0.8dBi)=13.05dBm=20 mW R =20 cm ∏= 3.1416 Solving for S, the power density at 20 cm is Band Test Result (mW/cm 2 )Limit Value (mW/cm 2 ) 802.11b 0.009 1.0 802.11g 0.004 1.0 802.11n HT20 0.004 1.0 802.11n HT40 0.004 1.0 Note: For mobile or fixed location transmitters, minimum separation distance is 20cm, even if TA Technology (Shanghai)Co.,Ltd. Test Report Report No.:RZA1202-0233MPE01 Page 6 of 6 calculations indicate MPE distance is less. This means that according to OET Bulletin 65 (Edition 97-01), Supplement C (Edition 01-01), the equipment fulfills the requirements on power density for general population/uncontrolled exposure and therefore fulfills the requirements of 47 CFR Part 15.247 (b) (5)
