JACKSON — AT&T is expanding and upgrading its wireless network in Mississippi.
The company said in a statement Thursday that it plans to add 50 cell sites in the state in 2011. More than 100 existing cell sites will be upgraded and capacity will be enhanced at sites across the state.
In 2010, AT&T says it added 50 new cell sites in Mississippi and upgraded some 90 existing sites to mobile broadband.
AT&T says the improvements are part of a $19 billion companywide capital investment this year.
