Abstract: Disclosed an open type electricity meter having an open type communication module. The module comprises a power line communication unit for separating a high frequency power line communication signal from a power line signal; a packet connecting unit for transmitting the communication signal received into the power line communication unit according to frame type to a corresponding processing unit as data, and packets data from a higher processing unit according to frame type to provide the same to the power line communication unit; a low speed data processing unit being connected to the packet connecting unit and installing a TCP/IP protocol engine to perform a remote measurement communication; a high speed data processing unit for performing a communication with the power line communication unit to transmit high speed data to an indoor communication terminal and to transmit the high speed data to an outdoor communication terminal through the packet connecting unit; and a telephony processing unit connected to an external audio processing unit for coding an audio signal from the audio processing unit to be provided to the packet connecting unit and decoding the coded audio signal from the packet connecting unit to be provided to the external audio processing unit. A low voltage distribution network can be applied as communication and subscriber networks to enhance the efficiency of the data communication.
