This paper deals with the absorption of RFenergy in human head caused by hands-free accessories compared to the handset alone. It was reported by others that hands-free kit may bring different influences to the SAR value in human head. The results of this study show the measurements results taken by the DASY4 system. The operating frequency is 1.8 GHZ and a particular designed SIM card is used. Two different mobile phones includingiphone 3GS are used in the measurements. Results presented here are useful in defining the radiation rate caused by adding hands-free close to human body. Research also indicates that using PDAs in front of human head can decrease the SAR value in human head.
