KTL EMC Test Report: 7F1040WUS1 Appendix G:MPE Calculation OET Bulletin No. 65, Supplement C 01-01 47 CFR §§1.1307 and 2.1091 2.1091 Radio frequency radiation exposure evaluation: mobile devices. A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimetres is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. In this context, the term ‘‘fixed location’’ means that the device is physically secured at one location and is not able to be easily moved to another location. Transmitting devices designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the 20 centimetre separation requirement. Prediction of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 where: S = power density P = power input to the antenna G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the centre of radiation of the antenna Maximum peak output power at the antenna terminal: 2.52 dBm Maximum peak output power at the antenna terminal: 1.78648757 mW Antenna gain (typical):-1.9dBi Maximum antenna gain:0.645654229numeric Prediction distance: 20 cm Prediction frequency: 2475 MHz Result Prediction Frequency (MHz) Maximum allowable antenna gain: (dBi) Power density (S) at prediction frequency: (mW/cm 2 ) MPE limit for uncontrolled exposure at prediction frequency: (mW/cm 2 ) Result 247534.492698550.0002291Pass 2 4R PG S Ä Ä

The apparatus was set up and exercised using the configurations, modes of operation and arrangements defined in this report only. Particular operating modes, apparatus monitoring methods and performance criteria required by the standards tested to have been performed except where identified in Section 1.7 of this test report (Deviations from Test Standards). For emissions testing, throughout this test report, “Pass” indicates that the results for the sample as tested were below the specified limit (refer also to Section 2, Measurement Uncertainty). Where relevant, the apparatus was only assessed using the monitoring methods and susceptibility criteria defined in this report. All testing with the exception of testing at the Open Area Test Site was performed under the following environmental conditions: Temperature : 17 to 23 °C Humidity : 45 to 75 % Barometric Pressure : 86 to 106 kPa All dates used in this report are in the format dd/mm/yy. This assessment has been performed in accordance with the requirements of ISO/IEC 17025.
