O FFICE OF 
THE CH A I RMAN 
The Honorable Peter A. DeFazio 
U.S. House ofRepresentatives 
2134 Rayburn House Office Building 
Washington, D.C. 20515 
Dear Congressman DeFazio: 
November 22, 2016 
I appreciate hearing from you concerning the importance of aligning Administration 
priorities before establishing rules for the 5.9 GHz wireless spectrum and the use of Dedicated 
Short Term Communications in connected vehicles . We currently are coordinating with the 
National Telecommunications and Information Administration (NTIA) and the Department of 
Transportation (DOT) to find the best method to deploy advanced automotive safety systems in 
the 5.9 GHz band, while working to meet existing and future demands for unlicensed spectrum. 
On October 7, 2016, the Commission released a Public Notice (PN) with an updated test 
plan for this band. The new test plan takes into consideration the comments we received from 
our June 2016 PN, and also reflects our ongoing coordination with NTIA and DOT. Please be 
assured that we will continue our cooperative work with our federal patiners, and consider all 
data and stakeholder concerns as we proceed with the testing process. 
Because of our commitment to transparency, the PN also listed the prototype devices we 
received and invited the public to an October 21 st Open House at the FCC's laboratory to learn 
more about this process. The Open House was attended by almost thirty participants, including 
representatives ofthe automotive industry, unlicensed wireless stakeholders, and device 
manufacturers. We have also scheduled onsite observations by interested parties throughout the 
testing period, and we have invited congressional staff to attend a special program at our 
laboratory testing facility on December 9, 2016. 
Thank you again for reaching out to me concerning your ongoing interest in this matter. I 
have attached the PN and the testing plan here for your records. If you or your staff are 
interested in attending the congressional program that we have scheduled, please contact our 
Office of Legislative Affairs at (202) 418-1900. We also are including your correspondence in 
the record of this proceeding so it can be considered as part of the public record that informs our 
next steps. 
Sincerely,_;~/
