【Abstract】 Based on the existing electric power communication system resources, this paper gives the design and implementation of a voice gateway based on Wi-Fi technology, which can set up voice communication network in emergency site, and can communicate with the emergency command center through the satellite network. The voice gateway combines the Wi-Fi technology and the IP PBX soft switch architecture, overcomes the defects of traditional voice communication mode, and improves the electric power communication system ability to ensure the stable operation of power grid. The practical test results have proven that the designed equipment can meet the application requirements.更多还原
