Hui Zhou Gaoshengda FCC Modular Approval Request Technology Co.,LTD Number:GF305 gy V0., Version: VO3 Date: 01-08-2011 To the FCC or FCC TCB handling this application Hereby we, Company name (grantee) Hui Zhou Gaoshengda Technology Co.,LTD Address NO.75 Zhongkai Development Area, Hulzhou, Guangdong, China City /ZIP / State / Country Huizhou, Guandong, China request modular approval for the certification of our equipment within this application, identified by:

Foc ID: 2AC23-WFTSRL1510C The table below contains the justification for modular approval of this equipment:

Requirement per DA 00-1407 Explanation from grantee (do not write yes/no, but explain why it complies / haw it is achieved) 1. The modular transmitter must have its own RF shielding, Yes

(The modular equip with own RF shielding case) 22. The modular transmitter must have buffered modulation/data inputs (if such inputs are | Yes provided) to ensure that the module will comply with Part 15 requirements under (The modular data inputs are buffered through log conditions of excessive data rates or over-modulation or microcontroler connections) 3. The modular transmitter must have its own power supply regulation. Yes

(RF voltage regulation is handled on the module) 44. The modular transmitter must comply with the antenna requirements of Section 15.203 Yes and 15.204(c). The antenna must either be permanently attached or employ a unique (The modular with permanently antenna, the antenna coupler (at all connections between the module and the antenna, including the _antennaiis FPC Antenna) cable). 5. The modular transmitter must be tested in a stand-alone configuration, je. the module | Yes must not be inside anther device during testing. This i intended to demonsirate thatthe (The modular during testing with @ USB adapter, module is capable of complying with Part 15 emission ims regardless ofthe device ino and the distance is greater than 10cm, so the which it is eventually installed. distance between modular and host system is greater than 10cm ) 66. The modular transmitter must be labeled with its own FCC ID number, and, fthe FCG Yes Dis not visible when the module is installed inside anther device, then the outside of (Please refer to FCC ID label) the device inlo which the module is installed must also display a label referring tothe enclosed module. This exterior label can use wording such as the following: Contains Transmitter Module FCC ID: XYZMODEL1 or Contains FCC ID: XYZMODEL". Any similar wording that expresses the same meaning may be used. The Grantee may ether provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization, 7. The modular transmitter must comply with any specific rule or operating requirements Yes applicable to the transmitter and the manufacturer must provide adequate instructions (Please refer to the modular installation muanual) along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are vvery strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured.

'8. The modular transmitter must comply with any applicable RF exposure requirements. Yes For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, (Please see the MPE report, the modular meets including 15.319(), 15.407(f), 15.253() and 15.255(g), require that Unlicensed PCS, MPE calculation of 47 CFR 1.107 (b)(1).) UNII and milimeter wave devices perfomm routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15,247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Modular transmitters approved under other Sections of Part 15, when necessary, may also need to address certain RF Exposure concerns, typically by providing specific installation and operating instructions for users, installers and other interested parties to ensure compliance.
