A Wake-Up Call From Craig McCaw

A Wake-Up Call From Craig McCaw: "McCaw's Clearwire Corp. has amassed enough licensed radio spectrum to create a nationwide, wireless broadband network based on an emerging technology called mobile WiMAX -- a powerful cousin of WiFi. Clearwire got a big boost on July 5, when Intel Corp. and Motorola Inc. pumped nearly $900 million into the company. The tech giants aim to turn WiMAX into a mainstream consumer technology and hope to make lots of money selling the chips, laptops, cell phones, and other gear that work with it."
