Brett Tarnutzer

Head of Spectrum

Brett Tarnutzer

Brett directs the association’s full range of spectrum-related activities, in collaboration with the GSMA membership.

Under Brett’s leadership, the spectrum team is focusing on areas such as the cost of access to spectrum. How regulators decide to determine the cost of access to spectrum bands has a big impact on the evolution of mobile services. It is essential that these costs are determined in a way that takes account of the necessary network investment that drives excellent service coverage. The team also works to facilitate the deployment of mobile spectrum bands and identify new bands, including preparing for World Radio Conference-2019, where spectrum for 5G will be a hot topic.

Prior to the GSMA, Brett worked for the US Federal Communications Commission (FCC) as Assistant Chief of the Wireless Telecommunications Bureau, dealing with a wide range of spectrum-related issues including designing the first-ever incentive auction for transferring spectrum from broadcast to mobile use.
