The voice communication unit, a codec (SLAC) connected to the mobile phone interface unit and the voice communication unit to support voice communication, and between the fax interface unit, the voice communication unit and the codec, the fax interface unit and the voice communication unit Is transmitted and received between the codec and the SLAC. It is configured to include the subscriber interface circuit (SLIC) to a data interface.

Preferably, the subscriber access device is powered from any one of a cigar lighter charger, a battery, a charger of the subscriber access device, and an AC / DC adapter.

According to the present invention as described above, the location of the wireless subscriber network device can be used while changing, and data communication and facsimile data transmission and reception are possible while moving.
