RE:  WT Docket No. 06-136
Request for Extension of Time
Fixed Wireless Holdings, LLC
Transition of the 2500-2690 MHz Band 
Transition Area:  BTA Number 36:  Bellingham, WA
Dear Ms. Sodos-Wallace:
On July 31, 2008, Fixed Wireless Holdings LLC, a wholly-owned subsidiary of Clearwire 
Corporation (together “Clearwire”), filed a Request for Extension of Time to complete the transition for 
Basic Trading Area (BTA) Number 36, Bellingham, Washington, which borders on Canada.1 On August 
7, 2008, Clearwire filed a second letter confirming that it had served a copy of the Request for Extension 
of Time on Nextel Spectrum Acquisition Corporation, the only other licensee to be transitioned in BTA 
36.2 For the reasons discussed below, we grant Clearwire’s request for a six-month extension of time to 
complete the transition of BTA 36.  
On November 2, 2006, Clearwire submitted an Initiation Plan for Bellingham, Washington BTA, 
which, as noted above, borders on Canada.3 According to the Commission’s Rules, Clearwire was 
required to complete the transition by August 1, 2008.4 Clearwire contacted Commission staff on how to 
proceed with the transition in a border area.5 As a result of this consultation, Clearwire contacted 
Canadian operators to obtain their consent to the transition.6 Clearwire reports that its discussions with 
Canadian operators are on-going.7 Clearwire asks for a six-month extension of time to complete the 
transition.8

We find that Clearwire has made a good faith effort to transition the Bellingham BTA by 
transitioning licenses held by itself and the Nextel Spectrum Acquisition Corporation, contacting the 
Commission on how to proceed with a transition on the U.S./Canadian border, and working with the 
relevant Canadian operators.  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.  Thus, we grant Clearwire an Extension of Time to transition BTA 36:  Bellingham, 
Washington until February 2, 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 Request for Extension of Time filed by Fixed Wireless 
Holdings, LLC on July 31, 2008 IS GRANTED, and the time for completing the transition in the 
Bellingham, Washington Basic Trading Area (BTA 36) IS EXTENDED TO February 2, 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
