RE:  WT Docket No. 06-136
Requests for Extension of Time
Fixed Wireless Holdings, LLC
Transition of the 2500-2690 MHz Band 
Transition Areas: BTA Number 174:  Greensboro-Winston Salem/High Point, NC
BTA Number 376:  Roanoke, VA
Dear Ms. Sodos-Wallace:
On October 16, 2008, October 30, 2008, and December 16, 2008, Fixed Wireless Holdings, LLC, 
a wholly-owned subsidiary of Clearwire Corporation (together “Clearwire”), filed Requests for Extension 
of Time to complete the transition for the Basic Trading Areas (BTA) noted above.1 For the reasons 
discussed below, we grant Clearwire’s requests and extend the deadline for completing the transition in 
those BTAs to February 28, 2009.  
Clearwire submitted Initiation Plans for the BTAs in question on January 16, 2007.2 According 
to the Commission’s Rules, Clearwire was required to complete the transition by October 17, 2008.3  
Clearwire claims that there have been difficulties involved in getting the pre-transition operations of 
Station WGW371, licensed to Unison Spectrum, LLC (Unison) and licensed to Digital Broadcast 
Corporation (DBC), discontinued.4 Clearwire also states that it is focusing on integrating its business and 
existing services with Sprint Nextel’s operations into a new company.5  
We find that Clearwire has shown good cause for a brief extension.  It appears that no party 
would be prejudiced by a grant of this extension.  We note that copies of the requests were served on the 
affected licensees, and no objections were filed.6 Thus, we grant Clearwire an extension of time to 
transition the BTAs noted above until February 28, 2009.

We remind DBC, Unison, and Clearwire that they should all be acting in good faith to complete 
the transition to the new band plan.  We expect all parties to act in good faith to communicate with each 
other and to take such steps as are necessary to complete the transition by the extended deadline.
Accordingly, IT IS ORDERED, pursuant to Section 4(i) of the Communications Act of 1934, as 
amended, 47 U.S.C. § 154(i), and Sections 1.46 and 27.1232(b)(1)(vi) of the Commission’s Rules, 47 
C.F.R. §§ 1.46, 27.1232(b)(1)(vi) that the Requests for Extension of Time filed by NSAC, LLC on 
December 16, 2008 ARE GRANTED, and the time for completing the transition in the Basic Trading 
Areas listed above IS EXTENDED TO February 28, 2009.
This action is taken under delegated authority pursuant to Sections 0.131 and 0.331 of the
