COMCAST Corp, the largest US cable operator, said on Monday it is introducing a wireless service for subscribers to access the Web beyond their homes anywhere within the United States. The so-called fourth-generation (4G) wireless service, is the first execution of a partnership between Comcast, Clearwire Corp and other companies that use the emerging WiMax high-speed mobile technology. Many consumers already update their blogs and watch videos using their mobile phones. Cable companies such as Comcast and Time Warner Cable Inc do not want to become irrelevant by restricting subscriber access to the home.
