Analysis Report Report No.: 13051823HKG-001 The Equipment Under Test (EUT) is a Streaming Media Box, equipped with HDMI, USB, LAN, SD Interface, audio and video output. The EUT contains a 2.4GHz WiFi module (RL-UM02L) operates in the frequency range from 2412MHz to 2462MHz at 802.11b,g,n HT20 (11 channels with 5MHz spacing), while 2422MHz to 2452MHz at 802.11n HT40 (7 channels with 5MHz spacing). The EUT is powered by an external AC/DC adaptor with 5VDC output. The adaptor accepts 100 – 120VAC only. WiFi Antenna Type: Internal, Integral (single antenna) 802.11b, 802.11g, 802.11n (HT20): 2412MHz – 2462MHz, 11 channels, 5MHz spacing 802.11n (HT40): 2422MHz – 2452MHz, 7 channels, 5MHz spacing The WiFi modules was tested in according with the following power output and in actual application the below limit shall not be exceeded. Operating Mode Nominal Radiated Field Production Antenna Strength Tolerance Gain 802.11b 100.8dBµV/m at 3m ±3dB 0dBi 802.11g 98.6dBµV/m at 3m ±3dB 0dBi 802.11n (HT20) 95.2dBµV/m at 3m ±3dB 0dBi 802.11n (HT40) 93.6dBµV/m at 3m ±3dB 0dBi According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 103.8dBµV/m at 3m in frequency 2.412GHz at 802.11b mode, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 7.2mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 7.2mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.462) mW = 9.56 mW Since the above conducted output power is well below the SAR Exclusion threshold level, so the EUT is considered to comply with SAR requirement without testing.
