IoT is the current mainstream trend in technology. In this way, we will discuss the industrial changes and market opportunities of the digital revolution, and will further analyze the technology and application fields of IoT.

In recent years, advanced countries have carried out power grid upgrade plans. To promote energy conservation and carbon reduction policies, Taiwan has advanced the Automated Metering Infrastructure (AMI) as one of its national energy conservation and carbon reduction plans, with 4G/5G and other communication industries included in the plan. The development and integration of smart grid applications and 5G communication technology will be important industrial advances worth paying attention to.
