Mobile Broadband Internet-cdma Solutions

For its mobility and facility, mobile communication technology has changed people's lives, people's needs for network communication keep increasing. It is hoped to effect multimedia communication, including data, voice and image, anytime, anywhere and with any person. Wireless data communication has got the priority in future. Internet CDMA technology is a new technology with 1.25MHz FDD bandwidth, mobile spectrum compatibility, broadband air interface and infrastructure technology, which was developed by Tantivy. It can be operated over existing PCS or cellular network to support broadband data rates for wireless use.The consisting principles and key technologies of I-CDMA system were analyzed in this thesis. Special attention was paid to study the designing principle of I-CDMA network in the aspects of RF design and data communication network design. Based on the mobile wireless broadband project of TYASIC, a preliminary design proposal and relative test plan for the city of Shenzhen were finished.
