Network access device with low-power-consumption remote wakening mechanism

The invention provides a network access device with a low-power-consumption remote wakening mechanism. One of embodiments of the network access device comprises a signal transmitting and receiving circuit, a demodulator circuit and a control circuit. The signal transmitting and receiving circuit is used for receiving a network signal, and the demodulator circuit is coupled with the signal transmitting and receiving circuit and used for generating a data frame according to the network signal received by the signal transmitting and receiving circuit. The control circuit is coupled to the demodulator circuit and used for wakening at least a part of components of an electronic device when at least two fields of the data frame fit a preset value or when a data frame comprising a specific field fits a specific receiving sequence.
