Aquapac
Aquapac is a registered trademark and brand name of a UK-based manufacturing company, Aquapac International Limited, specializing in waterproof cases and bags. The privately owned company was formed in 1983 and holds patents worldwide on systems for sealing bags and cases. The range commenced with a waterproof case for the original Sony Walkman known as the ‘Aquaman’, followed by cases for handheld VHF radios. Following Motorola’s invention of the first cellphone Aquapac launched the world’s first waterproof cellphone case. Nokia was an important customer for these cases during the 1990s, as were cellphone operators such as Deutsche Telekom and NTT DoCoMo. Aquapac went on to launch waterproof cases for other handheld electronics such as cameras and eReaders. The company operates out of factories in London, England.
History of telecommunication
Over several years starting in 1894, the Italian inventor Guglielmo Marconi worked on adapting the newly discovered phenomenon of radio waves to telecommunication, building the first wireless telegraphy system using them. In December 1901, he established wireless communication between St. John's, Newfoundland and Poldhu, Cornwall (England), earning him a Nobel Prize in Physics (which he shared with Karl Braun) in 1909. In 1900 Reginald Fessenden was able to wirelessly transmit a human voice.
