Network reliability is an important indicator of power terminal communication access network. This paper describes a wireless WAN communication terminal. The terminal has multiple SIM modules built in, which can monitor the communication quality of wireless access network in real time, and automatically switch the network according to the monitoring situation, which can greatly improve the reliability of power terminal communication access network, So as to meet the communication reliability requirements of power business. Combined with the communication quality requirements of power services, two channel quality detection methods and channel switching methods of wireless networks are analyzed.
