VR Entertainment Ltd VR Real Feel Alien Blasters (63737), VR Shooting/ Blaster Weapon (95503, 73521, 73522, 73525, 74038, 00887, 50960, 02069, 03060)
Analysis Report The Equipment Under Test (EUT) is a 2.4GHz Transceiver (VR gaming device) designed to be operated as a controller via BLE (2402-2480MHz with 2MHz channel spacing). The EUT is powered by 3*1.5V AAA battery. After being paired with the app, the EUT would be able to interact with the app. Antenna Type: Internal integral antenna Antenna Gain: 0dBi Nominal rated field strength: 91.1dBμV/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 94.1dBμV/m at 3m in frequency 2.4GHz, thus; The EIRP = [(FS*D) ^2*1000 / 30] = 0.771mW Conducted power = Radiated Power (EIRP) – Antenna Gain So; Conducted Power = 0.771mW. The SAR Exclusion Threshold Level: = 3.0 * (min. test separation distance, mm) / sqrt(freq. in GHz) = 3.0 * 5 / sqrt (2.480) mW = 9.53 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.
