A fixed mobile convergence (FMC) communication apparatus using a wideband audio codec is provided. The FMC communication apparatus includes an application processor which is capable of processing one or more wireless communication protocols and supports a wideband audio codec; a wideband audio signal input/output (I/O) unit which is connected to the application processor and processes the input and output of wideband audio signals; a mobile network access unit which is connected to the application processor and accesses a mobile communication network; and a wireless local area network (LAN) access unit which is connected to the application processor and wirelessly accesses an access point (AP). The FMC communication apparatus can access the base station of a mobile internet system or the base station of a mobile communication system. In addition, the FMC communication apparatus can access a Bluetooth device or an AP using a short-range wireless communication method. Moreover, the FMC communication apparatus can provide high-quality voice call services and various multimedia internet services by using a wideband audio codec.
