Abstract
Receiving sensitivity deterioration in wireless communication due to a spurious radiation wave generated from a card reader/writer is suppressed in a case where a mobile phone terminal is provided with a contactless IC card reader/writer or a contactless IC card. The mobile phone terminal provided with the contactless IC card reader/writer performs measurement of a wireless status upon reception (step S) and transmission power wetting (step S), and when an instruction to start a reader/writer function is inputted from a user (step S), wireless status deterioration due to spurious radiation from the reader/writer is predicted (step S). Then, the mobile phone terminal judges whether control to reduce the transmission speed is necessary or not, on the basis of a value of the deterioration predicted wireless status (step S), and when judged necessary, the transmission speed is reduced (step S).
