The names Gutenberg and Morse are associated with the invention and development of printing technology. Their hard work and sacrifice has enabled them to revolutionize how we read and communicate through the printed medium.Johann Gutenberg was born in the German city of Mainz in the year 1400. Gutenberg worked as a goldsmith and gem cutter as a young man and had learned about metallurgy. He is considered the inventor of the movable type printing in Europe. The first type was cast our of metals that included lead, antimony, and tin, and consisted of two-hundred and ninety separate symbols. Gutenberg also had to find an ink that would not fade. He later produced ink out of boiled linseed oil and soot. Gutenberg adapted a wine press for printing that was waist-high and had a rolling tray so that he could slide the paper in and out. The press would also enable him to squeeze water out of the damp paper while printing at the same time. Gutenberg’s invention sparked many religious revolutions that allowed the common man to posses a Bible for his own interpretation. Gutenberg's invention of the printing press allowed knowledge and ideas to be passed from one man to the other and paved the way for schools and media. Analog television broadcasts, which operate between the 54 MHz and 698 MHz television frequencies, are slated to cease operating per a United States Senate mandate in February 2009. This is also the timetable that the white space coalition has set to possibly begin offering wireless broadband services to consumers. The delay allows enough time for the United States Federal Communications Commission (FCC) to test the technology and make sure that it does not interfere with existing television broadcasts. Similar technologies could be used worldwide as much of the core technology is already in place. [2]
It was thought in 2005 that the value of the entire U.S. analog television spectrum could reach more than $20 billion at government auction. [3]
The White Spaces Coalition formed in late 2006[citation needed], soon after the Senate set the date to cease analog broadcasts.
Unfortunately, many companies (like those making wireless audio systems) that already use these TV bands have to now grapple with the fact that their wireless PA systems will no longer function properly if unlicensed devices are to now be able to operate within the same spectrum. Solutions at all major companies are currently pushing for deployment of their new products by Feb. 2009.
