Test Report #: BOTHO-003-15001_MPE FCC ID: 2AEUPBHACM001 Date of Report: 07-17-2015 IC: 20271- BHACM001 4 RF Exposure Limits and FCC and IC Basic Rules For the specific described radio apparatus the following basic limits and rules apply for both, FCC and IC where not indicated differently. 4.1 Power Density Limits acc. to FCC 1.1310(e) / RSS-102 i5, cl. 4: FCC Frequency Range (MHz) Power density (mW/cm2) Averaging time (minutes) 1500 – 100.000 1.0 30 IC 300 – 6000 0.02619 x f (MHz) 0.6834 6 4.2 Routine Environmental Evaluation Categorical Exclusion Limits acc. to FCC 2.109(c) / RSS-102, cl. 2.5 (rounded to 1 decimal point): FCC operating frequency > 1.5GHz: excluded if ERP < 3.0W / 34.8dBm; IC 300MHz ≤ operating frequency < 6 GHz: excluded if EIRP < 0.0131 x f (MHz) 0.6834 Per KDB 447498 D01 FCC allows calculative estimation of RF exposure for mobile applications when routine environmental evaluation categorical exclusion applies and also for fixed applications. When categorical exclusion cannot be claimed for mobile applications MPE measurement is required for TCB approval. RSS-102 of Industry Canada does generally not require RF exposure evaluation for fixed or mobile applications which stay below the given exclusion limits. 4.3 RF Exposure Estimation (MPE Estimation) Having available the source based average output power and peak antenna gain or the ERP/EIRP of the specified device and for a known minimum distance of it’s radiating structures from the body of persons according to it’s use cases (at least 20cm) the power density at that distance can be estimated by the following formula for plane-wave equivalent conditions (far-field conditions), when ground reflection is neglected. PG S 4R 2 where: S = power density (mW/cm2 or W/m2) P = power input to the antenna (mW or W) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (cm or m) Page 5 of 6

FCC / IC Limits for Total EIRP duty Routine Environmental Transmission Max. simultaneous trans cycle Evaluation excluded? Mode EIRP missions intra-band Applicability, (worst cases only) EIRP dBm % dBm dBm Wi-Fi 2.4 GHz 21.96 44 n.a. 36.9 / 34.3 yes Result: The equipment is categorically excluded from Routine Environmental Evaluation. 5.2 Compliance with MPE (Power Density) limits Limits: Smax @ 1850MHz and @ 2400MHz = 1.0mW/cm2; The highest power density is resulting from the formula: S = EIRP / 4*π*r2; The power density is calculated for the minimum distance r = 20cm; Highest source base time peak EIRP with WLAN 2.4GHz: 21.96dBm; Resulting maximum power density at 2400MHz: S(2400MHz) = 0.031 mW/cm2 Result: The equipment fulfills the MPE limits for the minimum distance between the antenna and the human body of 20cm. 5.3 Simultaneous Transmission MPE Test Exclusion (per KDB 447498 D01) not applicable. 5.4 Maximum allowed Antenna Gain – Gmax not applicable since fixed internal antenna is used in the product. 6 Revision History Date Report Name Changes to report Report prepared by 2015-07-17 BOTHO-003-15001_MPE First Version Danh Le Page 6 of 6
