FCC ID : U5MWD-MSB We would like to answer for limited Single Modular Approval in accordance with the requirement of rule part 15.212 as described below No. Requirements Comment Comply (Y/N) 1 The radio element of the modular transmitter has its own shielding Refer to the external photo Y 2 The modular transmitter must have buffered modulation data/inputs (if such inputs are provided) All input to the modules are buffered through microprocessor inputs. Y 3 The modular transmitter must have its own power supply regulation. Internal power regulators Refer to the Block-diagram Y 4 The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). Refer to the internal photo Y 5 The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. The EUT was tested in a standalone configuration via a SD extension cable Refer to the test setup photo Y 6 The modular transmitter must be labeled with its own FCC ID. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module Refer to the user manual Y 7 The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements Refer to the user manual Y 8 The modular transmitter must comply with any applicable RF exposure requirements Refer to the RF exposure statement for more details.

Applicant Address : 7th~8th FL, Miraeasset Venture Tower, 685, Sampyeong-dong, Bundang-gu Seongnam-si, Gyeonggi-do, Korea Kind of Product : WIFI Module Equipment model name : WD-MSB RF power : 14.41 dBm Peak Conducted Antenna type : Chip antenna Antenna Gain : 3.91 dBi Frequency Range : 2412 - 2462 MHz CTK Co., Ltd. 386-1, Ho-dong, Cheoin-gu, Yongin-si, Gyeonggi-do, 449-100, Korea Tel: +82-31-339-9970 Fax: +82-31-339-9855 www.e-ctk.com Page 2 of 2 ** MPE Calculations ** The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user. The MPE calculation for this exposure is shown below. The peak radiated output power (EIRP) is calculated as follows: EIRP = P + G Where, P = Power input to the antenna (mW) G = Power gain of the antenna (dBi) EIRP = 14.41 + 3.91 = 18.32 dBm => 67.92 mW The numeric gain(G) of the antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain / 10) G = Log -1 (3.91/ 10) G = 2.46 Power density at the specific separation: S = PG/(4R 2 π) Where, S = Maximum power density (mW/cm 2 ) P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) S = (67.92)/(4 * 20 2 * π) S =0.014 mW/cm 2 The Maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density at 20cm does not exceed the 1 mW/cm 2 limit. Estimated safe separation: R = √(PG / 4π) Where, P = Power input to the antenna (mW) G = Numeric power gain of the antenna R = Distance to the center of the radiation of the antenna (20cm = limit for MPE) R = √(67.92 / 4π) R = 2.32 cm
