This document presents the RF Exposure Evaluation for the device with FCC ID 2AYIT-CK1. The evaluation adheres to the criteria outlined in KDB 447498 D01 V06 and FCC PART2.1091, ensuring compliance with Maximum Permissible Exposure (MPE) limits for human exposure to radio frequency radiation. The report details the limits for both occupational/controlled and general population/uncontrolled exposures across various frequency ranges.
The Friis transmission formula is used to calculate power density, considering output power, antenna gain, and distance. Test procedures involve software-controlled transmission and reception at different channels. The report includes tables summarizing field strength, EIRP, output power, and power density at a specified distance for various wireless technologies such as Bluetooth (BT), Wi-Fi (802.11b/g/n), and LTE bands (2, 4, 5, 13, 66). The results demonstrate that the device complies with the MPE limits. Simultaneous transmission analysis is also performed, confirming that the sum of MPE ratios remains below 1.0, ensuring overall compliance.
