  1. Future Broadband Wireless Communication Mobility Testing Platform Ph.D, Prof. Fuqiang Liu, Xuefeng Yin Broadband Wireless Communication and Multimedia Institute Embedded System and Computing-service Lab , Ministry of Education School of Electronics and Information Engineering Tongji University http://wm.tongji.edu.cn

  2. Tongji University’s Campuses Anting auto town; Auto Electronics Siping Campus Anting Campus Shanghai

  3. Outline • Broadband Wireless Testbed(WiMAX/4G) • 4G Testbed Shanghai Platform • Tongji’s work in 4G • Vehicle Broadband Wireless Research and simulation • Testing Platform • Channel Emulation for Mobility Testing

  4. Testbed design(Shanghai) 临空经济园区建筑物分布图 临空经济园区分布式组网小区规划图 临空测量站址示意图

  5. Framework of Shanghai 4GTest

  6. Base on the characters of the project, the indicators of the networking test should focus on the performance evaluation of the system. Tongji’s work in 4Gtest

  7. DEMO__MIMO based wireless network evaluation system demonstration

  8. Networking Testbed Architecture Channel Testbed

  9. Features of DSRC • Dedicate short rang communications (DSRC) ,IEEE802.11p • 75 MHz of band available in U.S. • Twice the bandwidth of cellular • Approved by FCC • Primary allocation • Allocation incentive was safety • Range: Up to 1000 meters • Data Rate: Up to 27 Mbps • Tolling will probably use default data rate of 6 Mbps • Mobile connection: up to 120 mph • High Availability & Low Latency (50ms) Prioritization Service

  10. Service-Oriented Research • Safety: improving driving safety and/or traffic efficiency • Non-safety: providing information and/or entertainment to the driver

  11. Hybrid Framework Vehicle Broadband Wireless Network Research (funded by National High-tech Research and Development Program (863 Project))

  12. Research Topics Realistic mobility model Multi-channel Coordination Mobility prediction Data dissemination Cluster-Based Routing Protocol Power Power Control Session Maintenance Maneuver

  13. Realistic mobility model Traffic flow characteristics -Vehicles speed range -Lanes number -Vehicles density -Lane changing features -Traffic regulation

  14. Multi-Channel Operation North America FCC 1999 DSRC: 172-184, 7 channels Channel Coordination Channel Assignment

  15. Mobility Prediction Nodes can rebuild new routes by sensing its neighbours' movements unnecessary prediction (<200): A->C1、C2、C3 safe transmission (200<R<240): A->C4 change route (240<R<250): A->D->Cn Mobility prediction

  16. Cluster-Based Routing Protocol • Intra cluster : emergency messages, etc. • Inter cluster : non-emergency and long-distance messages, etc.

  17. Simulation Scenario DSRC Simulation in NS2

  18. Testing Platform Scene

  19. DEMO__DSRC

  20. Outline Broadband Wireless Testbed(WiMAX/4G) 4G Testbed Shanghai Platform Tongji’s work in 4G Vehicle Broadband Wireless Research and simulation Testing Platform Channel Emulation for Mobility Testing
