FEDERAL COMMUNICATIONS COMMISSION 
WASHINGTON 
OFFICE OF 
THE CHAIRMAN 
The Honorable Michael Bennet 
United States Senate 
261 Russell Senate Office Building 
Washington, D.C. 20510 
Dear Senator Bennet: 
July 27, 2016 
Thank you for your letter supporting the Commission's efforts to identify spectrum for 
5G technologies and encouraging us to initiate a rulemaking to explore increased flexibility for 
the future use of Multichannel Video Distribution and Data Service (MVDDS) spectrum for 5G 
mobile broadband services. 
I share your commitment to ensuring that the United States maintains its leadership in 
wireless innovation as the world transitions to the next generation of wireless technology, 5G. If 
we build off of the spectrum policies that led to our success in 4G - creating flexible licensing 
and technical rules- we will continue to lead the wireless revolution. To that end, the 
Commission recently adopted the Spectrum Frontiers Order and Further Notice of Proposed 
Rulemaking (FNPRM) that dramatically increases the amount of spectrum available for 5G 
services. 
We initiated our Spectrum Frontiers proceeding with the goal of acting incredibly quickly 
to make new spectrum available. I am pleased that we were able to vote on rules less than 1 0 
months after launching this proceeding. But our vote this month is not the end. We will 
continue to push to consider additional bands that might be capable of facilitating next 
generation technologies and have proposed a number of additional bands in the FNP RM. At this 
point, the Spectrum Frontiers proceding continues to focus on bands above 24 GHz. However, 
spectrum bands like the MVDDS band that fall below the 24 GHz band may indeed hold 
potential for future wireless technologies and services to take hold, and there may be an 
opportunity to consider these bands in the future. 
In addition, a petition for rulemaking asking the Commission to permit MVDDS 
licensees to use their spectrum to provide mobile broadband service was recently filed with the 
Commission. Consistent with our customary practice, this petition was placed on Public Notice 
to afford all interested parties an opportunity to file comments. Comments in response to the 
petition were due last month, and Commission staff is reviewing the record that developed in 
response to this petition.

I appreciate your interest in this matter, and my staff will endeavor to keep you informed 
as these proceedings progress. Please let me know if I can be of any further assistance.
