1. A wireless terminal device comprising:
- a first communication unit which performs wireless communication by a first wireless communication system defined in IEEE 802.11;
a display unit;
a controller which, when power of the display unit is turned OFF in an active state of the first wireless communication system, determines whether or not data communication is being performed by the first wireless communication system, andwhen it is determined that the data communication is not being performed by the first wireless communication system, makes the first communication unit transfer to a power save mode defined in IEEE 802.11.
