1. Megaconference IV and Mobile Satellite Video Dr. Bob Dixon Chief Research Engineer OARNet Ohio State University H.323 Forum Conference Nov 15, 2002 New York, New York

2. The Megaconference is: World’s largest Internet video conference. EVERYONE is invited. A professional conference with no central location. The speakers and audiences are distributed throughout the world. Fully interactive. Worldwide network of Multipoint Control Units, cascaded together. A test and a push for the state of the art.

3. Megaconference Growth Year Number of Organizations Participating ----------- ---------------------------------- 1999 50 2000 100 2001 200 2002 400 ???

4. We cannot continue to grow at this rate. Quantity vs Quality? Raise the technical bar for participation 768K speed rather than 384K H.263 codec rather than H.261 ViDeNet Global Dialing System Must successfully participate in at least one rehearsal

5. Schedule Details The date is December 10, 2002 Registration deadline is Nov 27. Presentation proposal deadline is Nov 15. Rehearsals are Nov 15, Nov 26 and Dec 3. Three sessions. Everyone can be in all. Early - emphasize Europe Midday - emphasize Western Hemisphere Late - emphasize Asia and Pacific

6. Megaconference Contents Nine presentations will be given by expert end-users of H.323 technology, on the topics of Distance Learning, and Far Away Places. A roving satellite dish team will participate from a number of exotic locations. An international game, with a prize. A roll call, to give everyone a chance to say hello to the world. Fantastic door prizes. The Megacon café, where anyone can talk to anyone.

9. Transportable Satellite Internet System

10. Transportable System Design Goals Provide high-speed Internet access for ALL purposes, including computers, telephones and PDAs. Inexpensive to build and operate Off-the-shelf parts for easy duplication Easy to operate by one person with one day training, with no hand tools. Small and light Reliable and adaptable to diverse field conditions Easily modified

11. Some Initial Applications Provide distance learning in underconnected locations such as rural areas and inner cities. Demonstration / Evaluation for a future fixed installation. Link field research to campus computers and laboratories and collaborators worldwide. Link field instruction and demonstrations to campus classrooms. Link field activities to remote databases, eg via PDAs. Special events, conferences, fairs, disasters, etc. Remote monitoring of construction projects.

12. Satellite Trailer Subsystems Dish and Radio Transceiver Power Leveling and Aiming Heating and Cooling External Connections Computer

13. Ground Station Power Alternatives (ALL are provided) Local Power Outlet unlimited (long extension cord) Batteries via UPS at least 8 hours before (computer controlled) recharging Gasoline generator at least 24 hours before (pushbutton start) refueling Type of power Running Time

14. Aiming System Satellites are 2 degrees apart in the sky; aiming accuracy must be better than 1/2 degree. GPS Receiver provides accurate local position to PC. PC calculates azimuth, elevation and polarization settings. Dish is aimed with precision compass and inclinometer, using simple adjustments. Azimuth - motor drive Elevation - hand operated turnbuckle No hand tools required.

15. Weatherproof Equipment Rack Cabinet Mounted on shock absorbers. Automatic thermostatically controlled heater. Automatic thermostatically controlled ventilation fan. No actual air cooling. Use parasol if needed. Contents: Radio transceiver UPS and batteries (more batteries elsewhere) Spectrum analyzer Ethernet switch Laptop PC and docking station Local wireless access point Power line frequency meter

16. Computing System Laptop PC in docking station Runs 3 special programs: Satellite aiming Dish Transceiver control and monitoring UPS control and monitoring Also supports all Internet access such as: Web browsing Email H.323 Video Conferencing Distance Learning tools
