POWER LINE COMMUNICATION APPARATUS, ACCESS POINT EQUIPMENT AND METHOD FOR MANAGING QUALITY OF COMMUNICATION SERVICE

摘要

The present invention provides a power line communication apparatus for managing communication quality. The power line communication apparatus comprises: a power line communication unit for transmitting and receiving data signals through a power line; a communication quality monitoring unit for monitoring the communication quality of each relay equipment based on the intensity of a data signal received from each relay equipment or based on whether a data signal is received; and a link approval request unit for transmitting a communication link approval request signal to second relay equipment when the communication quality of communicatively connected first relay equipment among the relay equipment corresponds to communication link change standards. Thus, a transition to a better environment is enabled by grasping the deterioration of communication quality or a communication-disabled state due to various environment changes in the power line communication, and maintenance costs can be reduced by reducing power consumption.
