Σ2: Max MPE ratios. Because the WIFI and WCDMA, WIFI and LTE can be operated simultaneously, for detailed calculation results please refer to the table above, so standalone SAR measurements are not required. Note For a more detailed features description, please refer to the RF Test Report. **********************THE END**********************
