Written by the developers of the new 21st century HF (high frequency) radio technology, this groundbreaking resource presents the powerful new capabilities and technical details of 3G and WBHF (wideband high frequency) waveforms to help professionals understand and use the ionospheric channel for video and high-speed data transmission. Featuring more than 180 illustrations, this practical book enables engineers to utilize this technology to communicate voice and data over the horizon without needing anyone else's infrastructure, send video beyond line of sight from moving platforms, and communicate over long ranges at such low power that it is nearly undetectable. Readers learn the rationale behind the new US and NATO standards for HF radio communications directly from their developers. Additionally, the book looks at the future direction of this technology area and the open problems requiring further research.
