Wireless communication device and wireless communication method

A wireless communication device comprising:

• a first wireless module which receives data;
• a second wireless module which is capable of receiving data and which has a longer communication distance than the first wireless module, wherein a communication speed of the first wireless module is faster than a communication speed of the second wireless module;
• a storage which stores data received by the first wireless module or by the second wireless module;
• a communication judging module which judges whether the first wireless module is continuing to receive the data, or has disconnected communication;
• a threshold value retaining module which retains a threshold value used to judge whether or not to permit a switch of the communication from the first wireless module to the second wireless module;
• a remaining volume monitoring module which judges, in response to a judgment by the communication judging module that the first wireless module has disconnected the communication, whether a volume of remaining unreceived data to be incorporated into the data received by the first wireless module before disconnection of the communication is smaller than the threshold value retained by the threshold value retaining module;
• a controller which switches the communication from the first wireless module to the second wireless module, the second wireless module receiving the remaining unreceived data, in response to a judgment by the remaining volume monitoring module that the volume of remaining unreceived data is smaller than the threshold value;
• and
• a display;
• wherein when the remaining volume monitoring module judges that the volume of remaining unreceived data is not smaller than the threshold value, the controller judges whether or not it is possible to continue the communication by the first wireless module after disconnection, and
• wherein the controller has a movement instructing module which instructs, when the controller judges that it is not possible to continue the communication by the first wireless module, a user to move and enter a range where the communication by the first wireless module is possible by displaying an indicator on the display.
