According to one embodiment, a communication apparatus includes a communication unit that establishes at least one proximity wireless connection with a communication partner apparatus. The communication apparatus includes a connection monitoring unit that monitors the communication unit and detect establishment of the wireless connection. The communication apparatus includes an execution control unit that identifies an establishment history of a plurality of the wireless connections based on a result of monitoring by the connection monitoring unit and, based on the establishment history, controls a process execution unit that executes at least one process.

Communication apparatus, processing method and computer-readable recording medium

A wireless communication device has a power receiving wireless communication unit configured to receive power and perform wireless communication utilizing the power, a storage unit configured to store a portion of the power, and a first wireless communication unit configured to perform wireless communication faster and more efficiently than the power receiving wireless communication unit by utilizing the power stored in the storage unit, when amount of the power stored in the storage unit exceeds a first reference level. The power receiving wireless communication unit includes a power receiver configured to receive power and supply a portion of the power to the storage unit, and a second wireless communication unit configured to perform wireless communication slower and less efficiently than the first wireless communication unit by utilizing the power received by the power receiver.

Wireless communication device, power transmitter, and IC card device

A wireless communication device according to an aspect of this invention includes a main body antenna to communicate with the antenna of a wireless card, and an antenna position setting unit capable of setting a plurality of types of positional relationships between the antenna of the wireless card and the main body antenna.

Wireless communication device adjusting antenna position and wireless communication method of adjusting antenna position

A wireless communication system performs wireless transmitting and receiving of data between first and second communication devices. The device transmits from the first communication device to the second communication device a prescribed signal by a prescribed carrier signal having a prescribed carrier frequency. The prescribed signal transmitted from the first communication device is received in the second communication device. The device generates in the second communication device a signal of prescribed frequency which is phase synchronous with the prescribed carrier signal. Transmission data is spread spectrum modulated using the signal of prescribed frequency generated in the generating step. The spread spectrum modulated signal is transmitted from the second communication device to the first communication device. The first communication device receives the spread spectrum modulated signal transmitted from the second communication device.

Wireless communication system and data storage medium

A read request signal containing a command, an address, etc. is subjected to two-phase modulation with the first carrier of a first frequency and the resultant signal is then transmitted to a radio card. After the transmission of the read request signal, the first carrier is kept transmitted to the radio card. Upon reception of the read request signal, the radio card generates a power supply voltage and an operation clock and sends response data to the read request signal to a radio card reader/writer. Unlike in the prior art, therefore, the reception of power or the reception/transmission of data need not be performed intermittently so that a large amount of data can be received or transmitted continuously at a high speed.
