This document presents the Radio Frequency (RF) exposure evaluation for the ARSRUR device, adhering to FCC guidelines outlined in KDB 447498 D01 V06 and part 2.1093. The evaluation determines whether the device meets the Specific Absorption Rate (SAR) test exclusion thresholds for general population exposure conditions, specifically for standalone 1-g head or body and 10-g extremity SAR.
The report details the calculations and measurements performed to assess RF exposure levels for various operating frequencies, including Bluetooth (BT) and Wi-Fi bands (2.4G, 5.1, and 5.8 GHz). The evaluation considers factors such as maximum power output, tune-up tolerance, minimum test separation distance, and RF channel transmit frequency. The results are compared against established SAR limits to ensure compliance.
The document includes tables summarizing the field strength, EIRP, maximum tune-up power, frequency, minimum distance, calculated thresholds, and limits for each operating band. The conclusion states that a SAR test is not required because BT and WIFI cannot transmit simultaneously, and the calculated thresholds are below the specified limits.
