Cingular Wireless today said it will spend $12 million this year to extend coverage and enhance the quality of service for customers in Nebraska. The company expects to add approximately 31 cell sites in the state this year. Last year, Cingular invested over $6 million on its network in Nebraska, adding coverage and capacity via new cell sites, new switching complexes, portable generators and back-up batteries, and by rolling out new data features. This local investment was part of Cingular's estimated $6.2 billion national network capital expenditure program during 2005. Wasn't aware that so many Cingular customers existed in Nebraska.
