Conventional multi master modems have the problem of response delay. Signal amplification by power amplification circuit and network unification by a master modem and multi CBU using Power Line Communication have been studied to control efficiently Reefer Container. And then we improved response delay via a master modem and multi CBU control method by reducing communication layer. The delay time for controlling the 100 containers was maximum 400 seconds; however, the delay time was reduced to 10 seconds by multi CBU. The signal reduction could be amplified from 13Vp-p to 24Vp-p by using developed power amplification circuit. The reliability of Power Line Communication Chip-Set was very stable in transmission test at reliability of 10??.
