Design and implementation of terminal system based on the next generation FMC using Wi-Fi and WiBro

摘要

Recently, the demanding requirements and use for wireless communication are increased and continue to grow. WiBro is trying to compete with Wi-Fi in coverage and data rate, while the inexpensive Wi-Fi still very popular in both personal and business use. This paper designs and implements Fixed Mobile Convergence (FMC) terminal system supported IEEE802.11 b/g/n Wi-Fi and WiBro. Terminal system of this study is used S3C6410 ARM11 core CPU and supports Voice over IP (VOIP) service, Push to Talk (PTT) and various multimedia services. So, The newly developed FMC terminal, including these features, is available Smart-phone, radio and more. Especially, it can be used efficiently at army communication and heavy industry communication. To improve voice service quality, along with providing voice mobility functions over current IP based network, service scenarios are proposed by providing seamless mobility in heterogeneous network among WiFi, 3G, 4G, mobile WiMAX (WiBro). To apply IEEE802.11 b/g/n Wi-Fi, we adopted Linux based android platform. By using network analyzer and TDS, we will analysis and measure frequency characteristic and trace charactistic of Wi-Fi module supported MIMO feature and signal wave of FMC terminal.
