FCC ID: 2ALCD-H7A RF EXPOSURE EVALUATION EUT Specification EUT Wireless Voice Intercom Doorbell Model Name H7A Frequency band (Operating) WLAN: 2.412GHz ~ 2.462GHz WLAN: 5.18GHz ~ 5.32GHz / 5.50GHz ~ 5.70GHz WLAN: 5.745GHz ~ 5825GHz Others( 467.63792MHz) Device category Portable (<20cm separation) Mobile (>20cm separation) Others ___ Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Max. output power 90.56 dBuV/m (-4.6975dBm)(0.3391mW) Antenna gain 0 dBi Evaluation applied MPE Evaluation SAR Evaluation Standard Requirement Portable Device According to §15.247(i) and §1.1307b(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. See KDB 447498 D01 General RF Exposure Guidance V6, section 4.3.1. The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, 16 where ·f(GHz) is the RF channel transmit frequency in GHz ·Power and distance are rounded to the nearest mW and mm before calculation17 ·The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. FCC ID: 2ALCD-H7A Measurement Result Channel Frequency (MHz) Max Output power (dBm) Max Output power (mW) Calculation Value (Note 1) Threshold Value 467.63792 -4.6975 0.3391 0.0464 3.0 EIRP=E-104.8+20logD= 90.56 -104.8+20log3= -4.6975dBm Note 1: Calculation Value =[(max. power of channel, mW)/(min. test separation distance, mm)] ·[√f(GHz)]. Fox example: 0.3391/5*√0.46763792= 0.0464 ≤3.0 According to KDB447498 D01 V6, threshold at which no SAR required is ≤3.0 for 1-g SAR, separation distance is 5mm, and no simultaneous SAR measurement is required. Standard Applicable According to 2.1093 this is a portable device. According to KDB 447498 D01 V6, Appendix A SAR test exclusion thresholds for below table, the power level 22mW at 5mm. Measurement Result: This is a portable device and the Max. peak output power is -4.6975dBm(0.3391mW) lower than low threshold 22mW at 5mm in general population category; The SAR measurement is not necessary.
