Title:
COMMUNICATION DEVICE, COMMUNICATION SYSTEM, AND LOCKING/UNLOCKING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/038890
Kind Code:
A1
Abstract:
The present invention performs locking/unlocking control on the basis of a positional relationship determined in consideration of obstacles between communication devices. This communication device comprises a distance generation unit and an inside/outside determination unit. The distance generation unit generates distance information on the basis of phase characteristics of the frequency of a propagation channel between the communication device and an other communication device. The inside/outside determination unit determines whether an obstacle is present between the communication device and the other communication device on the basis of the phase characteristics of the frequency of the propagation channel between the communication device and the other communication device. The communication device may further comprise a lock control unit that controls at least one of locking and unlocking on the basis of the distance information and a result of the inside/outside determination.
