Power line communication apparatus, power line communication system, and registration processing method
Abstract:
A power line communication apparatus controls a transmission using a plurality of parameters. The power line communication apparatus includes: a registration processor which performs a registration process for achieving a state to be communicable with another power line communication apparatus through a power line by use of transmission data based on a first parameter set at a first value and a second parameter set at a second value, a parameter controller which changes the first parameter to the third value to lengthen a communicable distance and the second parameter to the fourth value to shorten the communicable distance when the registration process has ended in failure. When the registration process has ended in failure, the registration processor retry the registration process by use of transmission data based on the first parameter set at a third value and the second parameter set at a fourth value.
