Sprint's 4G WiMax wireless broadband technology is expected to be available to 100 million customers in 2008; this is the first hard date I have heard regarding an introduction. WiMax is set to revolutionize the Internet: it offers faster connection speeds than current Wi-Fi systems and has an amazing broadcast range of 30 miles.
When WiMax is unveiled, first to customers in Washington D.C. and Chicago, it will offer 2-4Mbps speeds for $55 a month. Plus, WiMax will be “open access,” which means you’ll have free reign to the Internet just as with your broadband account. This new technology has the reliability and speed potential to replace cable and DSL lines as the new Internet connection of choice.
