Abstract:
1. A data transfer system in which wireless data transmission is carried out between a first device and a second device that each include an ultra wideband (UWB) wireless device which includes an ultra-short-range wideband antenna, the data transfer system comprising: a ranging section, provided in the UWB wireless device of at least one of the first and second devices, configured to measure a distance to the other of the first and second devices; a determination section configured to determine, based on a measurement result by the ranging section, whether or not the first device is in or on the second device; and a data transfer section configured to establish, using the ultra-short-range wideband antenna, a connection between the first and second devices when the first device is in or on the second device, wherein the ultra-short-range wideband antenna's characteristics regarding both a reflection characteristic and coupling characteristic become favorable for the UWB communication in a near field within one wavelength of a frequency used in the UWB communication.
