  • Patent number: 9019396
    Abstract: A wireless communication device, a memory device, a wireless communication system, a wireless communication method, and a program recordable medium are possible to attach positional information to image data without changing a hardware configuration of a device such as a digital camera capable of outputting image data. A memory I/F unit receives the image data to which positional information is attached from another device. A memory unit stores the image data input to the memory I/F unit. A storage data analyzing unit extracts the positional information from the image data when image data is stored in the memory unit. A system control unit causes the extracted positional information to be wirelessly transmitted from an RF unit to another wireless communication device.

  • Publication number: 20130272276
    Abstract: A wireless communication includes: a communication unit; a storage unit; a transmission buffer; and a controller. The communication unit wirelessly communicates with a reception terminal. The storage unit stores information relating to a timing at which the reception terminal changes from a first state to a second state. The first state is a state of being able to receive data and continues for a first period. The second state is a state of being unable to receive data and continues for a second period. The first period is extended by a fixed duration when the reception terminal in the first state receives data. The transmission buffer temporarily stores segmented data constituting transmission data to be transmitted to the reception terminal. The controller controls the communication unit to wirelessly transmit dummy data to the reception terminal by the timing if the segmented data is not stored in the storage unit.
