Infineon Technologies AG FCC ID: Q2331308 5 §1.1307(b) (1), §2.1091 - RF EXPOSURE According to §15.247(e)(i) and §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. Limits for General Population/Uncontrolled Exposure Frequency Electric Field Magnetic Field Power Density Averaging Time Range (MHz) Strength (V/m) Strength (A/m) (mW/cm2) (minute) Limits for General Population/Uncontrolled Exposure 0.3-1.34 614 1.63 *(100) 30 1.34-30 824/f 2.19/f *(180/f2) 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 * = Plane-wave equivalent power density 5.1 MPE Prediction (Tyco Antenna) 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 Maximum peak output power at antenna input terminal: 0.864 (dBm) Maximum peak output power at antenna input terminal: 1.22 (mW) Prediction distance: 20 (cm) Predication frequency: 2441 (MHz) Antenna Gain (typical): 4.0 (dBi) antenna gain: 2.51 (numeric) Power density at predication frequency at 20 cm: 0.0006095 (mW/cm2) MPE limit for uncontrolled exposure at prediction frequency: 1.0 (mW/cm2) 5.1.1 Test Result The EUT is a mobile device. The power density level at 20 cm is 0.0006095mW/cm², which is below the uncontrolled exposure limit of 1.0mW/cm² at 2441 MHz. Report #: R0702082-247 Page 11 of 34 FCC Part 15 C PCII Test Report
