Former admiral Jamie Barnett is stepping down as chief of the Federal Communications Commission's Public Safety and Homeland Security Bureau.
Barnett proposed the first nationwide test of the emergency alert system and led efforts to encourage Internet providers to increase cybersecurity. He also worked to develop next-generation 9-1-1 systems.
"Thanks to his efforts, our country's communications networks are stronger and more resilient, and Americans are and will be safer in significant ways," FCC Chairman Julius Genachowski said in a statement.
Barnett, who joined the FCC in 2009, will return to the Potomac Institute for Policy Studies as a senior vice president. When Barnett leaves at the end of the month, his deputy, David Furth, will serve as acting bureau chief.
