  1. WiMAX at the University of Wisconsin-Madison A Programmable Facility for Experimentation with Wireless Heterogeneity and Wide-area Mobility

  2. Overview • Mobility • Limitations • Possible Solutions • WiRover • GENI

  3. Mobility • Mobility a necessity • Multiple technologies to help out • Maybe work with 3G • Most work with Wi-Fi

  4. 3G & WiFi • 3G Cellular coverage • Inconsistent • Low throughput • Wi-Fi • Low coverage area • High throughput

  5. GENI WiMAX • WiMAX • High coverage area • High throughput • Solution • Utilize all available technologies

  6. WiRover • Multi interface • Cellular, WiMAX, and Wi-Fi • Main controller • Data collection mechanism • Ensures persistent data connection • Provides bandwidth aggregation • Gateway acts as Wi-Fi AP

  7. WiRover Reception • Increase in new users • Positive feedback from users • Highlighted in newspapers • Working with EMS for system in ambulances • 1st Place in 2011Wisconsin Governor’s Business Plan Contest

  8. GENI Capabilities • WiMAX • Live demo WiRover box with Intel 6250 (WiMAX) • OMF / OML server running for experimentation • Stationary node setup at UW Madison • Experimentation on a mobile platform that has many real users • High speed internet to mobile devices capable of running OMF experiments • In the near future • Connection to OpenFlowand GENI backbone • Handoff experiments between base stations • 3 additional base stations
