Cable Communication

The AMR (Auto Meter Reading) is needs to prepare separate IPs and communication lines for remote communication because DCU (Data Concentration Unit) and wideband modem are identical system required the resource to communication. It is the purpose of the literature to improve system stability and data reliability by means of integrating broadband cable communication part and PLC communication part within DCU. A PLC has some draw-backs in wideband communication because of absences of international standard specifications and the characteristic of power line. We integrated broadband cable modem and PLC modem in DCU. Therefore, the communication system is designed with unified board. PLC modem and broadband cable modem are designed to meet ISO/IEC12139-1 and international specified DOCSIS2.0 standard, respectively.

Medium voltage broadband power line communication is the key component of distribution automation communication. In this paper, medium voltage broadband buried cable communication system was studied. The buried cable communication channel model was established; Reference to the IEEE P1901 standard requirements, the broadband power line communication system based on OFDM was simulated; the transmission rate was tested with the experimental system. The simulation results and actual tests show that the broadband buried cable communication system has good performance and high transmission rate which can meet the requirements of distribution network automation.
