Shortwave radio were required. It was also difficult to beam the radio wave directionally with long wave, resulting in a major loss of power over long distances. Prior to the 1920s, the shortwave frequencies above 1.5 MHz were regarded as useless for long distance communication and were designated in many countries for amateur use. Guglielmo Marconi, pioneer of radio, commissioned his assistant Charles Samuel Franklin to carry out a large scale study into the transmission characteristics of short wavelength waves and to determine their suitability for long distance transmissions. Franklin rigged up a large antenna at Poldhu Wireless Station, Cornwall, running on
Radio Marconi “Most InAVative Leisure & Entertainment Facility” category at the InAVation Awards 2013, for the interactive multimedia seatback system integrated into the Royal Opera House in Muscat. The company is known mainly for its surtitle and supertitle systems, as well as the electronic libretto, seat back titles, and libretto translation technology. It is also known for its wireless and touch screen technology. These devices are not computer-based, resulting in no moving parts, no sound, and no overheating. These products allow users to view video channels, download content, and participate in surveys, among other applications. Radio Marconi systems can reproduce any existing
