Recent years, PLC technology has been transfered into some economies and into reality; however this research has successfully experimented the adaptation of PLC in transferring real time data (also measuring data) to aim at specific applications. The results can illustrate the capacity of PLC application with slow transmission speed to connect with the capacity of high transmission speed with an aim of enhancing technological applications in the power line. The conduct of experiments on system has clearly shown advantages of transmitting data through electric power line which are utilizing the existing electricity transmission infrastructure, no need of making new power-line, saving time and money; these advantages are evidently expressed in buildings which are already fulfilled with interior decoration. The author is hopeful that, in the very near future, we could discover specific places of application to strengthen the practicality of the research.
