Modern Marvels
Season 4 Episode 2 - The Telephone
From Alexander Graham Bell’s crude creation, to today’s high-speed wireless networks, we’ll look into the past, present and future of the telephone. We’ll visit the AT&T archives to see how the very first telephone boxes wired together with telegraph cables have evolved into vast wireless networks. Enter into the inner workings of Los Angeles County’s 911 emergency dispatch center, as well as explore advancements made by Lucent/Bell Labs in phone-embedded GPS technology. With telephone privacy issues making headlines, witness a demonstration of how easy it can be for someone to illegally tap your phone. We’ll also look at a technology developed by NASA-Ames that might one day allow people to converse by merely thinking what they want to say.
