Clearwire's $600 Million LTE Project will upgrade 66% of Clearwire's Sites

From Hope Cochran's presentation for the Bank of America - Merryl Lynch Media, Communications & Enterainment Conference 2011, Clearwire will be upgrading 10,000 of their 15,000 cell sites once they raise the necessary capital.  Hope stated 2/3 of their sites.  The capital would be spent on both core and radio access network equipment.  Each of their existing RAN vendors, Motorola, Samsung, and Huawei has a different path to LTE Advance, some only requiring a card swap, and some requiring a radio addition.
