Congratulations on your recent confirmation and swearing in as Chairman of the Federal 
Communications Commission (FCC). I look forward to working with you to ensure the Commission's 
policies foster the technological innovation and economic growth that make our country great, 
particularly on wireless issues. lam writing to high light one such technology: wireless microphones. 
For years, professional sports leagues, churches, performing arts venues, theme parks and other 
vital community institut ions and businesses have relied on wireless microphones for secure, clear, and 
efficient communications. No other technology provides the same balance of quality, rel iability, and 
affordability without the encumbrance of wires. For example, during each Miami Dolphins home game, 
more than 60,000 people pack Sun Life Stadium, and millions more watch on televisions worldwide. 
Invisible to these fans are the dozens of wireless microphones that make these games possible. Using 
wireless microphones, coaches communicate with players, referees consult with one another and inform 
fans, and sportscasters report to viewers. Quite simply, wireless microphones enable fans at the stadium 
and at home to enjoy the game, and they provide similar benefits for church congregations and theater and 
theme park patrons. 
In the current spectrum auction and repacking rulemaking, the FCC indicated it is considering a 
proposal to eliminate one or both of the channels that are dedicated to wireless microphones. I have heard 
from numerous stakeholders that could be negatively impacted by this el imination and that have filed 
comments at the Commission. Because wireless microphones are so vital to so many community 
institutions, I urge you to take these concerns into consideration when drafting the final auction and 
repacking rules. 
Like you, I embrace the potential of wireless broadband and fee l that our spectrum policies must 
accommodate new technologies. And I believe we can achieve this goal without compromising vital 
technologies that are essential to the operations of businesses and organizations across the nation. Thank 
you for your attention to this matter, and I look forward to working with you to promote the development 
and use of innovative communication technologies such as wireless microphones.
