The Rebirth of HF May 13, 2020 8am PT / 11am ET Sponsored by Rohde & Schwarz Presented by Paul Denisowski, Product Management Engineer, Rohde & Schwarz North America Webinar Overview Abstract: High frequency (HF) or “shortwave” communications were once the primary means of global connectivity, but over the last three decades this role has largely been taken over by both terrestrial Internet and satellites. However, recent improvements in our understanding of propagation as well as technological advancements have led to a “rebirth” of HF as a viable alternative for worldwide, mission-critical connectivity. This webinar begins by introducing the fundamental concepts behind the different modes of HF propagation, with particular emphasis on ionospheric or “sky wave” propagation, and explains how modern research enables more reliable and efficient use of this highly variable environment. This introduction is then followed by technical discussion of new developments, such as wideband HF, which enable the higher throughput necessary to make HF a practical means of modern, global communications. The webinar will then conclude with a live question-and-answer session. Sponsored by:
