This document presents the Radio Frequency (RF) exposure evaluation for the device identified by FCC ID 2AS7V-Y-SKR17. The evaluation is conducted in accordance with the guidelines outlined in 447498 D04 Interim General RF Exposure Guidance v01. The document details the formulas and thresholds used to determine whether Specific Absorption Rate (SAR) evaluation is required.
The evaluation considers factors such as transmitter output power, antenna gain, and measurement distance. Formulas are provided for calculating power thresholds based on frequency and distance. The document includes a table of example power thresholds for various frequencies and distances. The calculations demonstrate that the device's RF exposure levels are below the specified thresholds, indicating that SAR evaluation is not required.
The worst-case scenario is analyzed, and the field strength is measured at 90.68 dBμV/m at 3 meters at 2402 MHz. The antenna gain is -0.58 dBi, resulting in an antenna numeric gain of 0.875. The calculated power is 0.401 mW, which is less than the threshold of 2.72 mW. Therefore, the document concludes that SAR evaluation is not necessary for this device.
