I was recently asked to give an introduction lecture on ISAC and developed a brand new presentation for that purpose. I have now recorded a video based on that material. The lecture introduces the basic principles of ISAC, highlights similarities and differences between radar and communication systems, and discusses how and why sensing capabilities should be integrated into future cellular networks, including 6G.

The lecture covers:

• Fundamentals of wireless sensing and communication
• Classical radar features: range, velocity, and angle estimation
• Comparison of radar and communication propagation models
• Key differences between radar and communication systems
• Levels of integration in ISAC (site, hardware, and signal sharing)
• Potential internal and external use cases for ISAC
• Detailed examples of range, velocity, and angle estimation
• Trade-offs in waveform design, including the integration into OFDM systems
