Nokia said the acquisition is expected to boost company's network implementation services business and grow market share in the US.
The financial details of the deal were not disclosed.
"This acquisition builds upon Nokia Networks' existing network implementation service capabilities and is expected to increase its market share in this space," Nokia said in a statement.
SAC Wireless will operate as a wholly-owned subsidiary of Nokia and the transaction is expected to bring clear revenue synergies.
"With a national footprint and a proven track record of working with major telecom operators, SAC Wireless' capabilities complement our own in-house expertise. We believe this will enable us to build an even stronger foundation for our US services business," Nokia Networks Executive Vice President (North America) Ricky Corker said.
