50 m transmission distance without much fading loss. Under the sea, it can also reach around 10 m of range by using general low-cost coil antennas. Multiple MI nodes can be used to relay the data over a long distance. Magnetic Communications: From Theory to Practice introduces acoustic/magnetic communications from a science and engineering design perspective. It focuses on the following six topics: 1. Magnetic communications for wireless data/energy transfer, 2. Magnetic communication models, 3. Acoustic network routing protocols, 4. Acoustic network media access control (MAC), 5. Hybrid RF and acoustic communications, 6. Acoustic signal propagation models, Written for R & D scientists and engineers and academic researchers, throughout the book, it points out the future research trends. These trends are important to new product design because they describe the unsolved issues and help to enhance existing products (such as acoustic modem and MI coils) by overcoming those issues, it includes references to help you pursue in more depth these and related topics such as Ml-based under vehicle swarming control, the acoustic localization problem, hybrid acoustic/magnetic networking, and security and privacy issues in those systems.
