Abstract

A communication system includes a wireless network terminal (30), a wired network terminal (10), and a communication device (20). The communication device includes a Local Area Network (LAN) controller module (22), a process unit (24) and a transcoder (26). When the wired network terminal transmits a first kind of signal input to the communication device, the first kind of input signal is processed by the process unit and transformed into a first kind of output signal by the transcoder. Then the first kind of output is transmitted to the wireless network terminal. When the wireless network terminal transmits a second kind of signal input to the communication device. The second kind of input signal is transformed into the second kind of output signal by the transcoder. The second kind of output signal is processed by the process unit, and is then transmitted to the wired network terminal.
