A wireless communication medium includes an antenna, an analog signal
processor, a digital signal processor, and a central processing unit &
logic module. The antenna transmits and receives a signal to and from an
external apparatus. The analog signal processor converts an analog signal
to a digital signal, and converts a digital signal to an analog signal.
The digital signal processor demodulates the digital signal, detects the
start and end of data, and generates a first control signal for
determining whether data is transmitted to the external apparatus and a
second control signal for perceiving the end of data, blocking the
reception of data, modulating data, and determining whether modulated
data is transmitted to the external apparatus. The central processing
unit & logic module processes data received from and transmitted to the
external apparatus. Accordingly, an efficiency of processing a RF signal
can be improved.
