frequency networking feasible. 2.2.3.3.3 Service Demonstration Test Results In order to test the capability of the service load of the FuTURE TDD trial system, several kinds of different services were performed simultaneously on the platform in which HDTV service, videoconference, and high-speed FTP download services were all supported by wireless communication. 2.2.4 Achievements and Significance of FuTURE TDD System The ITU has named the 4G system "IMT Advanced" and will start its standardiza- tion around 2008. The research in basic theory and development of a corresponding trial system for the FuTURE TDD system has been accomplished. The first field trial system based on a distributed radio network has been established success- fully in Shanghai, and it has the basic characteristics of the 4G TDD mobile communication system. This system can provide radio transmission with a peak data rate of 100 Mb/s for high-mobility terminals and the demonstration of HDTV (Figure 2.17); the hardware platform can support wireless transmission with a data rate up to gigabits per second. It has the highlights of high spectrum efficiency and low transmission power, which represent the evolutionary trends of the next-generation mobile communication technologies. There are many innovations in radio network architecture, transmission, and radio resource management technologies for the next-generation wireless communication. In the development of the trial system, the FuTURE TDD special work- ing groups proposed 129 advanced technologies with independent intellectual properties, and most of them have been taken into practice. At the same time, some accumulated intellectual properties are devoted to 3GPP LTE and 3GPP2 © 2009 by Taylor & Francis Group, LLC Long Term Evolution: 3GPP LTE Radio and Cellular Technology AIE/UMB, and several standard proposals have been submitted to CCSA, 3GPP, and 3GPP2. Among them, BUPT has submitted more than 10 proposals to CCSA with 6 accepted, 3 proposals to ITU, 10 proposals to 3GPP2, and 30 proposal
