10x’s Bandwidth Increase in Wi-Fi Networks
I love the "IT Conversations":http://www.itconversations.com/ site. I try to download a few and listen to them while I'm working. You really do get a different experience listening to people speaking on these topics as opposed to reading them. "Ontology is Overrated":http://www.itconversations.com/shows/detail470.html with Clay Shirky and "Virtual Money":http://itconversations.com/shows/detail380.html with Peter Thiel, founder of "PayPal":http://www.paypal.com/, are a couple of my favorites.
Yesterday I listened to "an interview":http://www.itconversations.com/shows/detail558.html with Dr. Greg Raleigh about a "new wireless technology":http://www.networkworld.com/news/tech/2004/072604techupdate.html he developed. It takes advantage of _multi-path fading_, caused by the reflection of radio signals off walls and other objects, to increase the range of wireless signals. Effectively every reflection becomes an opportunity to send a new signal. This will lead to a 10x increase in bandwidth with no change in spectrum or power requirements in the upcoming wi-fi standard, 802.11n.
