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.
