Transcript

  • 1. Ottawa, Feb 4 2010 Seminar Presented at Industry Canada CRC-COVLAB Coverage Prediction Software Logiciel de Prédiction de Couverture Presented by: Doris Camiré
  • 2. Outline • Overview of CRC-COVLAB software • Show some of the most recent coverage studies done at CRC (case studies on DAB, HD Radio/FM-IBOC, ATSC-M/H). • Live CRC-COVLAB demo: building a project and showing custom work done for CBC/Radio-Canada, CRTC and COFETEL. • Live demo of free online web coverage service CRC-COVWEB. • Conclusion and questions.
  • 3. What is CRC-COVLAB? • Advanced scientific modelling software that performs coverage prediction and interference analysis for various types of communication systems. • Terrestrial, satellite applications? • Broadcast, wireless, telecom applications? • Public safety applications (national defence, customs agency, police force)
  • 4. History • Started as a small research project. • Simulate Single Frequency Networks (SFN) for broadcast application. • Grew to a sophisticated software.
  • 5. Our Clients Licensed throughout the world: North, Central, and South America, as well as Europe, Asia and Australia. Clients: governments, broadcast organisation, consultants, research labs, universities, national defense and public safety agencies.
  • 6. Database Compatibility • Digital Elevation Models: Covers the world (DTED, USGS, CDED, Computamaps, GLOBE30, SRTM1, SRTM3, and CRC (500m)). • Land Cover Models: Covers the world (DTED, Computamaps, CRC (500m)). • Ground Conductivity Models: Covers the world (FCC, ITU...). • Population Models: Covers North America (Canada, US, Mexico). • Broadcast Database Models: Covers North America (Canada, US, Mexico).
