Problems solved by technology

In these application networks, machine equipment terminals have high transmission power and long communication distances. Therefore, the existing M2M technology consumes a lot of power, and the wireless communication module embedded in machine equipment terminals must rely on external power to provide operating driving force. Existing M2M technology cannot be used when an external power supply is connected
