Page 7 of 9 Report No.: 190716004RFC-2 3.2.1.2 RSS-102 Issue 5 According to RSS-102 Issue 5, system operating under the provisions of this section shall be operating in a manner that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure. According to RSS-102 Issue 5, system operating under the provisions of this section shall be operating in a manner that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure. RF exposure evaluation is required if the separation distance between the user and/or bystander and the device’s radiating element is greater than 20 cm, except when the device operates as follows: • below 20 MHz6 and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1 W (adjusted for tune-up tolerance); • at or above 20 MHz and below 48 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 4.49/ƒ0.5 W (adjusted for tune-up tolerance), where ƒ is in MHz; • at or above 48 MHz and below 300 MHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 0.6 W (adjusted for tune-up tolerance); • at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10-2 ƒ0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz; • at or above 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 5 W (adjusted for tune-up tolerance). In these cases, the information contained in the RF exposure technical brief may be limited to information that demonstrates how the e.i.r.p. was derived. 3.2.2 Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. 3.3 MPE CALCULATION METHOD FCC 47 CFR Part 1 Subpart I S = PG/4πR^2= EIRP/4πR^2 S = power density (in appropriate units, e.g., mw/cm2) 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, the power gain factor is normally numeric gain. R = distance to the center of radiation of the antenna (in appropriate units, e.g., cm) 3.4 MPE CALCULATION RESULTS Note: For the test results, the EUT had been tested with all conditions. But only the worst case was shown in test report. 3.4.1 For WLAN For Wi-Fi function, operating at 2412MHz to 2462 MHz for IEEE802.11b/g/n 3.4.1.1 Antenna Type: Chain 0: PIFA Antenna 3.4.1.2 Antenna Gain: Chain 0: 2412MHz to 2462 MHz: 3.52 dBi Shenzhen UnionTrust Quality and Technology Co., Ltd.
