In order to prevent malfunctions of medical equipment caused by radio transmitters and other devices using radio waves, setting the separation distance according to the transmission output has been advised. Mobile phones are wireless transmitters that are used commonly within medical institutions and have many opportunities for unintentional proximity to medical devices. In order to suppress the output of the 4G handset, we set the parameters of the indoor base station system (IMCS) appropriately and measured the output of the 4G handset. It was found that the output of 10 mW in burst in the operating room and ICU setting that is well below the average power of 80 mW in burst of PHS. As PHS has a limited impact on medical devices and is used in medical institutions, it is consdered that the 4G mobile phone can be used in the operating room and ICU without affecting the medical equipment by setting the parameters of the 4G IMCS appropriately.
