Foreword In adopt with the Human Exposure IEEE C95.1, and according to the FCC 1.1310. The Maximum Permissible Exposure (MPE) is obligated to measure in order to prove the safety of radiation harmfulness to the human body. The Gain of the antenna used is measured in an Anechoic chamber. The maximum total power to the antenna is to be recorded. By adopting the Friis Transmission Formula and the power gain of the antenna, we can find the distance right away from the product, where the limit of the MPE is. 2.

The following shows only our observation have the greatest emissions.] According to OET BULLETIN 56 Fourth Edition/August 1999, equation for predicting RF fields, by the Friis Transmission Formula: Power density at the specific separation (portable): 22 22 /10345.1 )20(4 585.166.42 4 cmmW R PG S − ×= × == ππ Estimated safe separation: cm PG R320.2 4 585.166.42 4 = × == ππ Remarks: "The safe estimated separation that the user must maintain from the antenna is at least 2.320 cm." Where: S = power density (in appropriate units, e.g. mW/cm2) P = power input to the antenna (in appropriate units, e.g., mW) 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 (appropriate units, e.g., cm) The Numeric gain G of antenna with a gain specified in dB is determined by: G = Log -1 (dB antenna gain/10) G = Log -1 (2 / 10) = 1.585
