Dear Ms. Sodos-Wallace:
On November 13, 2008, wholly-owned subsidiaries 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 between February 12, 2007 and 
February 16, 2007.2 According to the Commission’s Rules, Clearwire was required to complete the 
transition by mid-November, 2008.3 Clearwire states that it is focusing on closing the transfer of control 
of licenses involving Clearwire and Sprint Nextel Corporation and integrating the two companies’ 
business and existing services into a new company.4

We find that Clearwire has made a good faith effort to transition the BTAs in question and that it 
has shown good cause for a brief extension.  It appears that no party would be prejudiced by a grant of 
this extension, particularly since licensees can continue operating pursuant to the old band plan until the 
transition is completed.  We note that copies of the requests were served on the affected licensees, and no 
oppositions were filed.  Thus, we grant Clearwire an extension of time to transition the BTAs noted above 
until February 28, 2009.  
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 subsidiaries of 
Clearwire Corporation on November 13, 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 
Commission’s Rules, 47 C.F.R. §§ 0.131, 0.331.  
Sincerely yours,
John J. Schauble
