US carrier AT&T has unveiled a massive plan to boost its network coverage, in a $14bn programme to boost its services for 300 million people.
The expansion plan, which will be completed by 2014, will include investments in both wireless and landline infrastructure.
AT&T expects to expand its service into a collection of growing markets which will eventually account for some 90 percent of its revenues.
"This is a major commitment to invest in 21st century communications infrastructure for the US and bring high-speed internet connectivity, 4G LTE mobile and wireline IP broadband, to millions more Americans," said AT&T chairman and chief executive Randall Stephenson.
The expansion comes as AT&T and other carriers work to restore services on the US Eastern Seaboard in the wake of superstorm Sandy. The storm, which caused extensive damage and flooding throughout the New York, New Jersey and New England regions.
Wireless carriers played an instrumental role in the recovery, allowing citizens and organisations who were without power to contact emergency services and co-ordinate rescue and relief efforts.
Investment in the expansion of both wireless and land-line infrastructure has been a top priority of the government under the Obama administration. With large expanses of rural and undeveloped land separating communities, many areas of the country have yet to be given access to broadband networks.
