Kirkland, Wash. – Craig McCaw, the telecom pioneer who
helped build wireless companies Nextel and XO Communications, has resigned as
the chairman of Clearwire, the wireless company he founded in 2003, according
to an SEC filing. McCaw had served as chairman of Clearwire for more than seven
years. The move comes as majority owner Sprint Nextel reportedly declined its
option to buy notes from Clearwire, which has been trying to raise upwards of
$1.2 billion to continue building out its nationwide mobile broadband network.
