THE FCC
Below is a description of the mission of the FCC taken from their website. Their primary role is to advance communications technology, help the US keep its competitive advantage and to auction or sell spectrum. Note there is nothing in their mission to monitor the health impacts of these technologies.
“The Federal Communications Commission regulates interstate and international communications by radio, television, wire, satellite and cable in all 50 states, the District of Columbia and U.S. territories. An independent U.S. government agency overseen by Congress, the commission is the United States' primary authority for communications law, regulation and technological innovation. In its work facing economic opportunities and challenges associated with rapidly evolving advances in global communications, the agency capitalizes on its competencies in:
Promoting competition, innovation and investment in broadband services and facilities
Supporting the nation's economy by ensuring an appropriate competitive framework for the unfolding of the communications revolution
Encouraging the highest and best use of spectrum domestically and internationally
Revising media regulations so that new technologies flourish alongside diversity and localism
Providing leadership in strengthening the defense of the nation's communications infrastructure”
