| Summary: | 碩士 === 國立臺灣科技大學 === 資訊工程系 === 93 === Along with the frequent promotion of the internet backbone bandwidth, the end-user also owns a large amount of transmission bandwidth because of the installation of ADSL and Cable Modem. Besides that, wireless LAN popularization and reducing the cost of wireless LAN has gradually turned the embedded system which can transmit a large amount of instant informations by wireless LAN connection to internet into the focus of the research and development of numerous manufacturers. The process mentioned above will gradually make the division of the products, such as traditional information, communication and electrical household appliances, etc. more blurred. The embedded network system which combines different fields like computer, communication and consumer etc., will soon become the main technology.
In this thesis, WLAN 802.11b, SIP protocol and embedded uClinux are combined to make a WIFI phone. About the main components select and the power saving mechanism improve, considering the saving of power, we make the WIFI phone of longer standby time. Because of the compatible characteristic of uClinux and Linux , we reserve the elasticity that will increase the new function in the future, compatibility and speed of development. And we also offer a good development platform for digital information household appliances in the future.
