RF EXPOSURE EVALUATION According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environment impact of human exposure to radio frequency(RF) Radiation as specified in ß1.1307(b) FCC ID: 2BRGN-DL-BTSW EUT Specification EUT Bluetooth switch module Frequency band (Operating) BLE: 2.402GHz ~ 2.480GHz Device category Portable (<20cm separation) Mobile (>20cm separation) Exposure classification Occupational/Controlled exposure (S = 5mW/cm 2 ) General Population/Uncontrolled exposure (S=1mW/cm 2 ) Antenna diversity Single antenna Multiple antennas Tx diversity Rx diversity Tx/Rx diversity Max. output power BLE BLE 1M: 2.86 dBm BLE 2M: 2.87 dBm Antenna gain (Max) -0.58dBi Evaluation applied MPE Evaluation SAR Evaluation Page 2 of 3 Limits for Maximum Permissible Exposure(MPE) Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density(mW/cm 2 ) Average Time (A) Limits for Occupational/Control Exposures 300-1500 -- -- F/300 6 1500-100000 -- -- 5 6 (B) Limits for General Population/Uncontrol Exposures 300-1500 -- -- F/1500 6 1500-100000 -- -- 1 30 Friis transmission formula: P d =(P out *G)\(4*pi*R 2 ) Where P d = Power density in mW/cm 2 , P out =output power to antenna in mW. G= gain of antenna in linear scale, Pi=3.1416 R= distance between observation point and center of the radiator in cm=20cm P d the limit of MPE, 1mW/cm 2 . If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. For multiple RF sources: Multiple RF sources are exempt if: in the case of fixed RF sources operating in the same time-averaging period, or of multiple mobile or portable RF sources within a device operating in the same time averaging period, if the sum of the fractional contributions to the applicable thresholds is less than or equal to 1 as indicated in the following equation Evaluated k : the maximum reported SAR or MPE of fixed, mobile, or portable RF source k either in the device or at the transmitter site from an existing evaluation at the location of exposure. Exposure Limit k : either the general population/uncontrolled maximum permissible exposure (MPE) or specific Absorption rate (SAR) limit for each fixed, mobile, or portable RF source k.
