Anti-miss alarm system, method, and shoe supporting anti-miss alarm using wireless personal area network

摘要

An anti-miss alarm system, method, and a shoe supporting the anti-miss alarm is provided. The anti-miss alarm method receives a radio signal emitted from a portable article having an interface for a wireless personal area network (WPAN), extracts channel status information from the radio signal, calculates a relative distance from the portable article based on the channel status information, and outputs alarm signals in a stepwise manner according to the relative distance. A mobile terminal includes an interface of a WPAN, a control unit, and an output unit. The interface receives radio signals emitted from a portable article having a similar interface. The control unit extracts channel status information from the radio signals and estimates a relative distance from the portable article based on the channel status information. The output unit controllably outputs alarm signals in a stepwise manner according to the relative distance. The shoe is similar
