Communication apparatus, and method and program for controlling the same

摘要

A communication apparatus comprises a reception unit that receives a reception signal from a metal cable and extracts reception data; a transmission unit that sends a transmission signal obtained by modulating transmission data with a frequency included in a first frequency band to the metal cable; an interference signal detection unit that detects a signal used in wireless communication, modulated by a frequency included in a second frequency band, and transmitted over the metal cable as an interference signal; and a signal transmission control unit that instructs the transmission unit to modulate transmission data using a frequency included in a third frequency band that does not have any frequency band overlapping the second frequency band when the interference signal is detected and a frequency band overlapping both the first frequency band and the second frequency band exists.

1. A communication apparatus, comprising:
a reception unit that receives a reception signal from a metal cable and extracts reception data; a transmission unit that sends a transmission signal obtained by modulating transmission data with a frequency included in a first frequency band to said metal cable; an interference signal detection unit that detects a signal used in wireless communication, modulated by a frequency included in a second frequency band, and transmitted over said metal cable as an interference signal; and a signal transmission control unit that instructs said transmission unit to modulate transmission data using a frequency included in a third frequency band that does not have any frequency band overlapping said second frequency band when said interference signal is detected and a frequency band overlapping both said first frequency band and said second frequency band exists.
