Federal Communications Commission 
445 12th Street Southwest 
Washington, DC 20554 
Dear Chairman Pai: 
The Federal Communications Commission's continuous work to marshal spectrum with the goal 
of improving broadband service yields enormous benefits to our country: economic growth, 
leadership in innovation, and the innumerable benefits of faster, better internet connectivity for 
all Americans. Beyond voice and data connectivity for individuals, wireless broadband powers 
telehealth, connected cars, smart communities, and supply chain management. As these 
demands increase, more spectrum resources are required. 
While the U.S. has pushed ahead with efforts to free new spectrum at both low and high 
frequencies, we lag behind other countries in so-called "mid-band" spectrum- the range of 
frequencies between 30Hz and 7 GHz. Europe, China, Japan, and South Korea are all moving 
ahead to allocate hundreds of megahertz of mid-band spectrum, for licensed and unlicensed uses, 
in anticipation of both new Internet of Things applications as well as rising demand for mobile 
broadband that can be met with small cell deployments. 
One way government can help augment the U.S.'s global leadership position is by looking for 
ways to encourage innovation and investment. To help achieve this goal, I introduced the 
MOBILE NOW Act to ensure that large swaths of wireless spectrum, including spectrum in the 
mid-band range, are made available for commercial use by the year 2020. For the U.S. to remain 
competitive as we see the rollout of the next generation gigabit wireless services, including 50, 
more spectrum must be made available to keep pace with ever-increasing demand. 
While I am hopeful that the Senate will pass the bipartisan MOBILE NOW Act in the very near 
future, I am pleased to hear that the Commission may be considering a new proceeding to 
identify new spectrum uses in a range of bands. As you look for ways to better utilize spectrum, 
I urge you to explore possible new allocations in the mid-band frequencies, perhaps including the 
3.7 GHz and 6 GHz bands, and to begin a rulemaking proceeding focused on opening mid-band 
spectrum for both licensed and unlicensed networks. 
Thank you for your attention to this matter and for your ongoing efforts to implement sensible, 
forward-looking spectrum policy. 
JOHN THUNE 
Chairman
