RF EXPOSURE Limit 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. Limits for Maximum Permissible Exposure (MPE) Frequency Electric Field Magnetic Field Power Density Averaging Time Range(MHz) Strength(V/m) Strength(A/m) (mW/cm²) (minute) Limits for Occupational/Controlled Exposure 0.3 – 3.0 614 1.63 (100) * 6 3.0 – 30 1842/f 4.89/f (900/f)* 6 30 – 300 61.4 0.163 1.0 6 300 – 1500 / / f/300 6 1500 – 100,000 / / 5 6 F=frequency in MHz *=Plane-wave equivalent power density Test Data 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: 28.44(dBm) Maximum peak output power at antenna input terminal: 0.698(W) Prediction distance: 10.4(cm) Predication frequency: 928(MHz) Antenna Gain (typical): 6 (dBi) Power density at predication frequency at 10.4 cm: 3.08(mW/cm²) MPE limit for controlled exposure at prediction frequency: 3.1 (mW/cm²) Test Result: Pass
