APPARATUS OF DISPLAYING CHANNEL INFORMATION FOR POWER LINE COMMUNICATION AND METHOD THEREOF

摘要

A PLC(Power Line Communication) channel information display device and a method therefor are provided to determine channel information through channel estimation to display the determined information to a user, thereby simply testing whether a channel is usable before a PLC device is installed. A channel information determiner(110) determines channel information which contains bandwidths usable by a user in the current PLC network through PLC channel estimation. A channel information display(120) displays the channel information to the user. The determiner comprises as follows. A data frame transmission time determiner(112) determines data frame transmission time required for transmitting overall data frames through the channel estimation. A hierarchical bandwidth calculator(114) divides size of data to be transmitted at each transmission hierarchy by the data frame transmission time, and calculates the bandwidths usable by the user.
