A wireless communication apparatus comprising a detecting means for detecting temperature inside the device; and a control means for It detected by the temperature detecting means becomes a preset first threshold value or more when the maximum transmission speed of the device itself can be realized to be limiting.
In order to prevent the improvement in communication speed and increase the output power and the temperature rise due to the small size and low cost to provide a mobile terminal device, a wireless communication apparatus comprising: detecting means for detecting temperature inside the device; and a control means for It detected by the temperature detecting means becomes a preset first threshold value or more when the maximum transmission speed of the device itself can be realized to be limiting.
