Angela Giancarlo, partner in the Mayer Brown Washington DC office, handles a multitude of complex matters within the technology, media and broadband communication sectors. A former Federal Communications Commission (FCC) official, Angela is well known for her deep substantive knowledge, strategic vision and exceptional leadership.

Angela counsels leading communication service providers, tech companies, wireless device manufacturers, automobile manufacturers, energy companies, and investors as to the legal, business and policy implications of proposed significant transactions; legislation and regulation; and enforcement actions; as well as spectrum auctions and allocations for new and existing technologies and services. Angela also secures approvals for proposed transactions that involve FCC-issued licenses. Prior to joining Mayer Brown, Angela served at the FCC for eight years, departing as chief of staff and senior legal advisor to Commissioner Robert McDowell, a post she held for five years. In this role, Angela negotiated countless mergers involving wireless, broadcast and satellite licenses, played an integral role creating protocols to ensure technical coexistence among 5G mobile Internet of Things offerings; and devised international spectrum frequency assignments and related policies as a member of the U.S. Delegation to the 2012 World Radio Conference.

A recognized thought leader, Angela was named a Top Lawyer by Cablefax in 2018—a “guardian of the rule of law”—for serving as “a key counselor as the media and communications sectors navigate a shifting landscape and for helping set the course for the industry in the age of convergence.” Angela is also recognized in Chambers USA and Legal 500 USA for her work on telecom matters.
