Analysis Report The equipment under test (EUT) was a 915MHz wireless self-emptying rain collector for measuring rainfall and temperature. The wireless rain collector sensor is fully assembled and calibrated for easy installation. It works together with a Display Main Unit which can remember the data for monitoring and analyzing the weather status. The EUT transmits data by a low power radio frequency to the Display Main Unit up to 150m away. Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength: 93.8dBμV/m at 3m Maximum allowed field strength of production tolerance: +/- 3dB According to the KDB 447498: Based on the Maximum allowed field strength of production tolerance was 96.8dBμV/m at 3m in frequency 2.4GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 1.436mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 1.436mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (0.915) mW = 15.68 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.

The EUT uses a permanently attached antenna which, in accordance to section 15.203, is considered sufficient to comply with the pervisions of this section. 2. Pursuant to FCC part 15 Section 15.215(c), the 20 dB bandwidth of the emission was contained within the frequency band designated (mentioned as above) which the EUT operated. The effects, if any, from frequency sweeping, frequency hopping, other modulation techniques and frequency stability over excepted variations in temperature and supply voltage were considered.
