EUT Description Product Name: GPS Tracker Model Name: ES610 Hardware Version: ES110-MB-H103 Software Version: LLB0003.1.4 RF Exposure Environment: Uncontrolled GSM/GPRS Support Band: GSM850/ PCS 1900 GSM 850: 824.2MHz to 848.8MHz Tx Frequency Range: PCS 1900: 1850.2MHz to 1909.8MHz GSM 850: 869.2MHz to 893.8MHz Rx Frequency Range: PCS 1900: 1930.2MHz to 1989.8MHz Type of modulation: GMSK Antenna Type: Internal GSM 850: 2dBi Antenna Peak Gain: PCS 1900: 2dBi Page: 3 of 5

Report No. : UL05420141126FCC027-1 2. RF Exposure Evaluation 2.1 Limits 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 1.1307(b) LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) Frequency Electric Filed Magnetic Filed Power Density Average Time Range(MHz) Strength Strength (mW/cm2) (Minutes) (V/m) (A/m) (A)Limits for Occupation/Control Exposures 300-1500 -- -- F/300 6 1500-100,000 -- -- 5 6 (B)Limits for General Occupation/UnControlled Exposures 300-1500 -- -- F/1500 6 1500-100,000 -- -- 1 30 F= Frequency in MHz Friis Formula Friis transmission formula: Pd = (Pout*G)/(4*Pi*R2) Where Pd = power density in mW/cm2 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/cm2 . 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. 2.2.Test Procedure Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. The temperature and related humidity: 18℃and 45％ RH. Page: 4 of 5

Report No. : UL05420141126FCC027-1 2.3.Test Result of RF Exposure Evaluation This device is evaluated by mobile device with general population/uncontrolled exposure condition For this device, the calculation is using the most conservative values, and the results are as follows: Maximum Calculated Antenna Average Average Output RF Exposure at MPE Limit Test Mode Gain Power EIRP Power d = 20cm (mW/cm2) (dBi) (dBm) (mW) (dBm) (mW/cm2) GSM 2 32.81 23.81 381.1 0.076 0.55 850 PCS 2 30.30 21.30 213.8 0.043 1.00 1900 The averaged power calculated method are shown as below: Averaged power=Maximum burst averaged power(1 Tx Slot)-9dB Duty cycle =12.5% Average EIRP Power=Average Power+Antenna Gain Calculated Peak Average RF Exposure ERP EIRP MPE Limit Test Mode EIRP EIRP at (dBm) (dBm) (mW/cm2) (mW) (mW) d = 20cm (mW/cm2) GSM 31.57 33.72 2355.0 296.5 0.059 0.55 850 GPRS 31.97 34.12 2582.3 325.1 0.064 0.55 850 PCS --------- 28.88 772.7 97.3 0.019 1.00 1900 GPRS --------- 28.95 785.2 98.9 0.020 1.00 1900 The frame-averaged power calculated method are shown as below: Average EIRP=Peak EIRP-9dB Duty cycle =12.5% This device can pass RF exposure limit.
