NOTIFYING METHOD AND WIRELESS DEVICE

摘要

A RF section (52) periodically receives signals sent from other terminal devices. In the case where the qualities of the signals periodically received are degraded lower than a second threshold value despite the fact that the intensities of the signals periodically received are higher than a first threshold value, a specifying section (72) detects the failure of other terminal device, i.e., the sender of the signals periodically received. A processing section (56), a modulating/demodulating section (54), the RF section (52) and an antenna (50) send signals which include the information of the fact that the failure has been detected and the information relating to the detection position.
