About this ebook
Light doesn't just travel in straight lines; it evolves through the architecture of its environment.
Traditional optical communication relies on a clear view, but modern indoor networking demands a deeper understanding of how light scatters, bounces, and lingers.
What are the benefits?
- Master the mathematical foundations of diffuse reflection and surface scattering.
- Predict temporal and spatial dispersion in complex indoor geometries.
- Optimize Non-Line-of-Sight (NLOS) link budgets for high-speed data.
- Bridge the gap between pure radiometry and practical channel modeling.
- Gain unparalleled depth with 210 curated concepts mapped across 21 chapter-specific appendices for comprehensive technical mastery.
