FCC ID:2BH4P-STONE1 RF Exposure Evaluation Limits 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 1.1307(b) Limits for Maximum Permissible Exposure (MPE) Frequency range (MHz) Electric field strength (V/m) Magnetic field strength (A/m) Power density (mW/cm 2 ) Averaging time (minutes) (A) Limits for Occupational/Controlled Exposures 0.3–3.0 614 1.63 *(100) 6 3.0–30 1842/f 4.89/f *(900/f 2 ) 6 30–300 61.4 0.163 1.0 6 300–1500 f/300 6 1500–100,000 5 6 (B) Limits for General Population/Uncontrolled Exposure 0.3–1.34 614 1.63 *(100) 30 1.34–30 824/f 2.19/f *(180/f 2 ) 30 30–300 27.5 0.073 0.2 30 300–1500 f/1500 30 1500–100,000 1.0 30 f = frequency in MHz Friis transmission formula: Pd = (Pout*G)/(4*pi*r 2 ) Where Pd = power density in mW/cm 2 , Pout = 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 Pd id the limit of MPE, 1 mW/cm 2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. Test Result of RF Exposure Evaluation BLE Mode Mode Frequency (MHz) Output power to antenna (dBm) Output power to antenna (mW) Antenna Gain (dBi) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result GFSK 2402 -0.6700.86 2.54 0.00017 1.0 PASS 2.4G WI-FI Mode Mode Frequency (MHz) Output power to antenna (dBm) Output power to antenna (mW) Antenna Gain (dBi) Power Density at R=20cm (mW/cm 2 ) Limit (mW/cm 2 ) Result 802.11b 2437 14.776 30.03 2.54 0.00597 1.0 PASS 802.11g 2462 13.660 23.23 2.54 0.00462 1.0 PASS 802.11n20 2462 12.650 18.41 2.54 0.00366 1.0 PASS Remark: The same antenna cannot transmit at the same time, So the transmntting corsideration: The ratio = ANT MPE(MAX) / limit = 0.00597 < 1.0.
