Page 1 of 2 Declaration of Electromagnetic Field Health Compliance To whom it may concern, As to the product RRU3261 made by Huawei Technologies Co., Ltd., we declare that it complies with the Basic restrictions/Reference levels for electric, magnetic and electromagnetic fields as specified in following standards(s): Nr. Standard 1 47CFR FCC Part 1 & OET Bulletin 65 The compliance is demonstrated based on the following calculation model assessment: 1. The power density according to far-field model is: 2 ),( 4R GP S      Where: P = input power of the antenna. G = antenna gain relative to an isotropic antenna. , = elevation and azimuth angles. R = distance from the antenna to the point of investigation. 2. For single or multiple RF sources, the calculated power density should comply with following: 1 ,   i iLimit i S S Where: i S = the power density when the f is i . iLimit S , = the reference level requirement for power density when f is i . 3. The calculation of the power density or safe distance is: NOTE 1: The RF exposure evaluation is base on the far-field and the radiation exposure is over-estimated. NOTE 2: The maximum output power level is taken into account as a worst case for the purpose of the calculation of power density or safe distance. NOTE 3: The minimum antenna feed cable loss (assumed no cable loss) is taken into account as a worst case for the purpose of the calculation of power density or safe distance. NOTE 4: The maximum antenna radiation exposure orientation and maximum antenna gain is taken into account as a worst case for the purpose of the calculation of power density or safe distance.
