RF Exposure evaluation FCC ID: 2BD9Z-CAST-LB540 Exposure category: General population/uncontrolled environment EUT Type: Production Unit Device Type: Mobile Device 1. Reference According to §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to §1.1310 and §2.1091 RF exposure is calculated. KDB447498 D01: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 2. Limit Limits for Maximum Permissible Exposure (MPE)/Controlled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 3.0 – 30 30 – 300 300 – 1500 1500 – 100,000 614 1842/f 61.4 / / 1.63 4.89/f 0.163 / / (100) * (900/f 2 )* 1.0 f/300 5 6 6 6 6 6 Limits for Maximum Permissible Exposure (MPE)/Uncontrolled Exposure Frequency Range(MHz) Electric Field Strength(V/m) Magnetic Field Strength(A/m) Power Density (mW/cm²) Averaging Time (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 3.0 – 30 30 – 300 300 – 1500 1500 – 100,000 614 824/f 27.5 / / 1.63 2.19/f 0.073 / / (100) * (180/f 2 )* 0.2 f/1500 1.0 30 30 30 30 30 F=frequency in MHz *=Plane-wave equivalent power density 3. MPE Calculation Method Predication of MPE limit at a given distance Equation from page 18 of OET Bulletin 65, Edition 97-01 S=PG/4πR² Where: S=power density P=power input to antenna 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 4. Antenna Information CAST-LB540 can only use antennas certificated as follows provided by manufacturer; Antenna No. Model No. of antenna: Type of antenna: Gain of the antenna (Max.) Frequency range: 2.4GWIFI / PCB antenna 1.95dBi for 2400-2500MHz 5.8GWIFI / PCB antenna 2.64dBi for 5745-5825MHz 5. Manufacturing Tolerance 2.4GWIFI Mode Max.
