Abstract
A communication apparatus configured to contactlessly communicate a baseband signal to another communication apparatus includes a transmission unit configured to stop output of a transmission signal, which is to be transmitted to the other communication apparatus, while a reception intensity of a reception signal received from the other communication apparatus is lower than a first threshold value, and a transmission coupler configured to be coupled to a reception coupler of the other communication apparatus by electric field coupling.
Claims12
A communication apparatus configured to contactlessly communicate a baseband signal to another communication apparatus, the communication apparatus comprising:
- a transmission unit configured to stop outputting a transmission signal while a reception intensity of a reception signal received from the other communication apparatus is lower than a first threshold value, wherein the transmission signal is to be transmitted to the other communication apparatus;
- and
- a transmission coupler configured to be coupled to a reception coupler of the other communication apparatus by electric field coupling.
A communication apparatus configured to contactlessly communicate a baseband signal to another communication apparatus, the communication apparatus comprising:
- a proximity detection unit configured to detect proximity to the other communication apparatus;
- and
- a transmission unit configured to stop outputting a transmission signal while the proximity detection unit does not detect the proximity to the other communication apparatus, and configured to output the transmission signal while the proximity detection unit detects the proximity to the other communication apparatus, wherein the transmission signal is to be transmitted to the other communication apparatus.
A method for controlling a communication apparatus configured to contactlessly communicate a baseband signal to another communication apparatus, the method comprising:
- outputting a transmission signal that is to be transmitted to the other communication apparatus;
- and
- stopping outputting the transmission signal while a reception intensity of a reception signal received from the other communication apparatus is lower than a first threshold value.
A method for controlling a communication apparatus configured to contactlessly communicate a baseband signal to another communication apparatus, the method comprising:
- detecting proximity to the other communication apparatus;
- and
- stopping outputting a transmission signal while the proximity to the other communication apparatus is not detected, and outputting the transmission signal while the proximity to the other communication apparatus is detected, wherein the transmission signal is to be transmitted to the other communication apparatus.
