As many as 24 million U.S. citizens have no access to broadband Internet service and are unlikely to get the higher-speed connection any time soon, the U.S. Federal Communications Commission said Tuesday. “The immediate prospects for deployment to them are bleak,” the Washington-based commission said in a statement. Between 14 million and 24 million live without Web service that can transmit at least 4 megabits per second, the agency said. The FCC recommended several measures to move closer to its goal of universally available broadband: releasing more spectrum for mobile broadband, allowing for more infrastructure to support the service and further data collection to help more U.S. citizens get broadband. The U.S. population is about 310 million, according to the Central Intelligence Agency. In March, the FCC released a plan to expand the availability of broadband throughout the U.S. The agency aims to boost the share of those using broadband at home to 90 percent from about 65 percent currently, and having at least 100 million households with connections of 100 megabits per second.
