Cingular Wireless will be spending more than $100 million this year to expand its network coverage into new areas and to enhance service in others, the company said Monday.

Cingular said nearly $55 million would be spent in North Carolina, capping more than $300 million in additions and expansion over the past three years.

Cingular plans to spend nearly $50 million across South Carolina. The firm invested more than $35 million in upgrades in that state in 2003.

The Charlotte, Raleigh and Wilmington areas are among those receiving additional or improved coverage.

In South Carolina, areas where coverage is to be expanded or improved include Columbia, Florence, Charleston, Greenville, Anderson and Spartanburg.

“Cingular’s focus in 2004 is to improve the overall customer experience and making continual investments in our network is a critical component of this effort,” said Rob Forsyth, vice president and general manager for Cingular Wireless-Carolinas. “We are focusing our resources on vastly improving coverage, particularly in residential and commercial areas and in-building locations throughout the region.”

Cingular’s network includes Global System for Mobile Communications (GSM) and General Packet Radio System (GPRS) technology, which is an enhancement of GSM, for high-speed data and other advanced services.
