Nokia has closed its acquisition of Fenix Group in a transaction that expands its portfolio of tactical communications platforms for defense customers.

Mike Loomis, president of Nokia Federal Solutions, said in a statement published Wednesday the completion of the acquisition marks a key step in advancing the company’s U.S. strategy and growing its defense business.

“Fenix‘s expertise in broadband tactical communications perfectly complements our existing offerings, and together we will be even better positioned to deliver high-performance, secure, and reliable solutions to our defense customers, helping them achieve mission-critical objectives,” Loomis added.

In December, Nokia announced that it agreed to buy Fenix Group as part of a push to broaden its wireless offerings portfolio for defense clients.

Fenix Group, most recently a portfolio company of Enlightenment Capital, is focused on developing 3rd Generation Partnership Project-based tactical communications systems that support military applications. The company’s products include the Banshee family and Talon MANET radios.
