The invention relates to an electronic device for wireless data transmission on the Internet. The device comprises a mobile component and a stationary one. The stationary component is connected to a telephone line and the mobile component is connected to the information processing apparatus for Internet access. The information processing apparatus is able to access the Internet and is equipped with a MODEM (Modulation and Demodulation) and USB (Universal Serial Bus) port. Both the MODEM (Modulation and Demodulation) and USB (Universal Serial Bus) port can be moved with the information processing apparatus. The electronic device is designed for wireless data transmission instead of wired Internet access as when the information processing apparatus has to be connected to a telephone line for Internet access.
