Abstract
An operation method and a radio device for controlling a power switch of a radio based on moving speed. The radio device includes a speed estimator and an operator. The speed estimator is used for estimating the moving speed of the radio device, and the operator is used for comparing the moving speed of the radio device with a speed threshold value so as to turn on/off the power switch of the radio device. The power switch of the radio device can be controlled based on the moving speed so as to decrease the time the radio device stays on, thus reducing the power consumption of the radio device.
