Abstract
A positioning relation taking an obstacle between communication apparatuses into consideration is grasped to perform opening/closing control with a key. The communication apparatus includes a distance generation section and an inside/outside determination section. The distance generation section generates distance information on the basis of a phase characteristic of a frequency of a propagation channel to and from another communication apparatus. The inside/outside determination section performs inside/outside determination on whether or not an obstacle is interposed between the communication apparatus and the difference communication apparatus, on the basis of the phase characteristic of the frequency of the propagation channel to and from the other communication apparatus. The communication apparatus may further include a key controlling section that controls at least one of locking and unlocking with a key on the basis of the distance information and a result of the inside/outside determination.
