    摘要： A method of distributing group identifiers IDs (GIDs) in a power line communication (PLC) network, a method of receiving the GIDs, an authentication apparatus, and a PLC apparatus are provided. The authentication apparatus includes: an authentication mode storing unit which stores an authentication mode having a value including one of an authentication authorized mode and an authentication unauthorized mode; a GID request receiver which receives a GID request message from a PLC apparatus; and a GID transmitter which, if the authentication mode is the authentication authorized mode, transmits a GID corresponding to the PLC apparatus to the PLC apparatus. Authentication is realized in a PLC media access control layer distributing the GIDs between a PLC apparatus and an authentication apparatus, so manually inputting a GID into the PLC apparatus is not necessary. Further, the GIDs are distributed via the authentication apparatus, thereby centrally managing the GIDs.

    摘要： Provided is an apparatus and method of displaying power line communication channel information. The apparatus for displaying power line communication (PLC) channel information includes a channel information determining unit which performs PLC channel estimation and determines channel information including a bandwidth which is available for a user in a power line communication network; and a channel information displaying unit which displays the channel information to the user. Since channel information is determined through channel estimation and displayed to a user, it is possible to easily check whether a channel can be used before installing a power line communication (PLC) device. In an application, information on kinds of a service which can be selected by the user or expected quality of the service can be previously checked. Accordingly, the user can know whether the communication can be performed, without installing a communication device or executing a communication application which requires much time and effort. Accordingly, it is possible to reduce time and effort necessary for finding an adequate communication point.
