US Patent 11683753 Wireless transmission system and power saving method thereof

A wireless transmission system comprises an antenna component, a wireless module including a processing unit and a power controlling unit, a tuner connected between the antenna component and the wireless module, and a sensor connected to the wireless module. The tuner is configured to adjust an output bad of the power controlling unit according to a received signal strength indication of the wireless transmission system being greater than a predetermined threshold value, such that multiple different load values are provided for the power controlling unit. The sensor is configured to detect and record a current consumption value corresponding to each load value. In response to the wireless module emitting signals via the antenna component, the processing unit selects the load value corresponding to the lowest of the current consumption values and applies the selected load value to the output load of the power controlling unit.
