PURPOSE: A wireless data communication device is provided to prevent wiretapping by encoding data when transmitting the data from a host CPU to a wireless interface unit. CONSTITUTION: A wireless interface unit(200) is composed between a host CPU(11) and a wireless signal processing unit(16) for converting a data format and performing a real-time process necessary for the wireless signal processing unit(16). An encoding block is composed between the host CPU(11) and the wireless interface unit(200). The encoding block encodes data when the data are transmitted from the host CPU(11) to the wireless interface unit(200) so that the data are not decoded without exchanging a normal key in the outside.
