A wireless wide area network (WWAN) to Ethernet converter comprises a subscriber identity module (SIM) interface, for accessing data stored in a SIM card; a radio frequency (RF) circuit, for receiving in the WWAM an RF signal associated with the data stored in the SIM card and for converting between the RF signal and a baseband signal; a digital signal processor (DSP), coupled to the RF circuit, for processing the baseband signal; and an Ethernet control device, coupled to the DSP, for converting between the processed baseband signal and an Ethernet signal.
