Abstract:
1. A power line communication apparatus for controlling a transmission using a plurality of parameters, comprising: 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, wherein when the registration process has ended in failure, the registration processor retries the registration process by use of transmission data based on the first parameter set at a third value; and a parameter controller which changes the first parameter to the third value and the second parameter to the fourth value when the registration process has ended in failure to adjust a communicable distance, wherein the first parameter is a signal intensity of a transmission signal for representing the transmission data, wherein the second parameter is an information volume to be superimposed on a carrier for transmitting the transmission data, and wherein the parameter controller increases the signal intensity to lengthen the communicable distance, and increases the information volume to shorten the communicable distance.
