Page 2 of 2 Report No.: GTI20190176F-2 Friis transmission formula: Pd=(Pout*G)\(4*pi*R2) Where Pd= Power density in mW/cm2 Pout=output power to antenna in Mw G= gain of antenna in linear scale Pi=3.1416 R= distance between observation point and center of the radiator in cm Pd the limit of MPE 1mW/cm2. If we know the maximum gain of the antenna and total power input to the antenna, through the calculation, we will know the distance where the MPE limit is reached. Measurement Result Max. Power Power Channel Tune up Max. Tune up Antenna Measured density at density frequency tolerance Power Gain Power 20cm Limits (MHz) (dBm) (dBm) (dBi) (dBm) (mW/cm2 ) (mW/cm2 ) 2405 9.67 9±1 10 2 0.00315 1 2440 9.68 9±1 10 2 0.00315 1 2480 -0.04 0±1 1 2 0.00040 1 Note For a more detailed features description, please refer to the RF Test Report. **********************THE END********************** CTC Laboratories, Inc. 1-2/F., Building 2, Jiaquan Building, Guanlan High-Tech Park, Shenzhen, Guangdong, China Tel.: (86)755-27521059 Fax: (86)755-27521011 Http://www.sz-ctc.org.cn For anti-fake verification, please visit the official website of Certification and Accreditation Administration of the People’s Republic of China : yz.cncaic.cn
