TRANSMITTER MODULAR APPROVAL ATTESTATION February 26, 2008 Federal Communications Commission Re: Application Modular Approval Certification for FCC ID: R68MPBGPRO Gentlemen: The following attestation addresses the eight requirements to support modular approval as required by the FCC Public Notice DA00‐1407 “Part 15 Unlicensed Modular Transmitter Approval” 1 The modular transmitter has its own RF shielding and does not rely upon the shielding provided by the device into which it is installed in order to comply with Part 15 limits. 2 The modular transmitter has buffered modulation/data inputs. All inputs to the modules are buffered through the radio circuitry. 3 The modular transmitter has its own power supply regulator. 4 The modular transmitter has an antenna that complies with section 15.203 and 15.204(c) of the FCC rules. It has a Reverse Polarity‐SMA type of connector at the transmitter end and is soldered to the antenna (depending on OEM configuration). The antenna used with the module was tested with the module. 5 The modular transmitter was tested in a stand‐alone configuration without a chassis during testing to show compliance with Part 15 emission limits. The transmitter module complies with the AC line conducted requirements found in Section 15.207. AC power lines. 6 The modular transmitter will be labeled with its own FCC ID. Also, the OEM host manufacturer will be informed to display a label referring to the enclosed module. The exterior label will read as follows: “Contains Transmitter Module FCC ID: R68MPBGPRO” or “Contains FCC ID: R68MPBGPRO”. 7 The modular transmitter is manufactured so that the user cannot influence the operation of the transmitter that will operate outside of the scope of the regulations. 8 The modular transmitter meets the MPE calculations of 47 CFR 1.1307(b)(1). If there are any additional questions or if further information is needed, please contact us at your earliest convenience at (949) 454‐8295. Sincerely, Rick Candelas Aegis Labs, Inc.

MPE Calculations Systems operating under the provision of 47 CFR 1.1307(b)(1) shall be operated in a manor that ensures that the public is not exposed to radio frequency energy levels in excess of the FCC guidelines. The EUT will only be used with a separation of 20 centimeters or greater between the antenna and the body of the user or nearby persons and can therefore be considered a mobile transmitter per 47 CFR 2.1091(b). The MPE calculation for this exposure is shown below. Using the Antennas with highest output power: The peak radiated output power (EIRP) is calculated as follows: Antenna Frequency (GHz) Power input to the antenna (P) (dBm) Power gain of the antenna (G) (dBi) EIRP (P+G) (dBm) EIRP Log -1(dBm/10) (mW) Wanshih (PN: WSS007) 2.4 20.37 5.00 25.37 344.35 EIRP = P + G Where P = Power input to the antenna (mW). G = Power gain of the antenna (dBi) The numeric gain (G) of the antenna with a gain specified in dB is determined by: Antenna Frequency (GHz) Antenna Gain (G) (dBi) Numeric Antenna Gain Log -1(dBm/10) (dB) Wanshih (PN: WSS007) 2.4 5.00 3.16 G = Log -1 (dB antenna gain/10) Power density at the specific separation: Antenna Frequency (GHz) Power input to the antenna (P) (mW) Numeric Power Gain of the Antenna (G) (dB) Maximum Power Spectral Density S=PG/(4R 2 π) (mW/cm 2 ) Maximum Power Spectral Density Limit (mW/cm 2 ) Wanshih (PN: WSS007) 2.4 108.89 3.16 0.069 1.00 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) The maximum permissible exposure (MPE) for the general population is 1mW/cm 2 . The power density at 20cm does not exceed the 1mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules.
