The Hedy Lamarr Foundation Vision: "1980s, Lamarr and Antheil's invention took on new significance. Instead of 'frequency hopping,' today's term is 'spread spectrum' but the basic idea is the same. The FCC recently allotted a special section of the radio spectrum for an experiment using the spread spectrum idea in a test designed to make cell phone calls more secure. A lot of corporate dollars have been invested in this process which has allowed more cell phone users to use the existing frequency spectrum." (2nd source)
