1STATEMENT OF 
COMMISSIONER MIGNON L. CLYBURN
Re:  Use of Spectrum Bands Above 24 GHz For Mobile Radio Services, GN Docket No. 14-177;
Amendment of the Commission’s Rules Regarding the 37.0-38.6 GHz and 38.6-40.0 GHz 
Bands, ET Docket No. 95-183 (Terminated); Implementation of Section 309(j) of the 
Communications Act – Competitive Bidding, 37.0-38.6 GHz and 38.6-40.0 GHz Bands, PP

Communications Coalition to Create Service Rules for the 42-43.5 GHz Band, RM-11664, 
Notice of Inquiry
All trends point to an ever increasing demand for advanced wireless services, which means that 
we need to both promote efficient uses, and reallocate more spectrum, for commercial benefits.  Since 
reallocating sufficient spectrum, to meet the needs of wireless consumers is a multi-year process, the time 
to start planning our mobile future, is now.  
While many wireless carriers are in the midst of deploying 4G networks, the industry is already 
calling for a Fifth Generation that will substantially exceed the capacity of existing mobile technologies.  
While there is no consensus on the definition of 5G, some believe it could accommodate an eventual 
1000-fold increase in traffic demand and support high-bandwidth content with speeds in excess of 10 
gigabits per second.  Achieving these objectives will likely require the development of new networks that 
will deliver service through multiple, widely-spaced frequency bands, using macrocells, microcells, 
unlicensed as well as licensed transceivers.  While some companies agree there is room for further 
efficiency gains in the bands below 3 GHz, they generally believe that provision of 5G-level service will 
require use of higher frequency bands, such as those above 24 GHz.
In planning for the future use of bands above 24 GHz, we need a better understanding of those 
state of the art and potential future developments in technology, for it will require us to study the best 
ways to manage interference among operators and other licensees that operate in the same or adjacent 
bands.  And of course, we want to spur creative ideas for the best licensing and authorization blueprints 
on mobile operations above 24 GHz.
So I commend the Chairman for starting the process with this Notice of Inquiry and thank Roger 
Sherman, Julie Knapp and their staffs at the Wireless Telecommunications Bureau and Office of 
Engineering and Technology for presenting this thoughtful item.
