Abstract: This Paper is about power-line voice communication over the low-voltage network. Power-line communications is the use of in-house power supply network for communication perseverance. Power-line network has very widespread arrangement in every building and power-line is developed for transmission of power at 50-60 Hz and 230 volts. Hence use of Power-line network for transmission of voice with power supply has increased considerations. The communication approach that eventually could be used for voice transfer over the power-line network is described. Power transmission is achieved by using the principle of superimposition of voce over power in power-line cables. The structure described can be improved and reformed for future requirements.
