KIRKLAND (WiMAX Day). Clearwire Corp said that today that it has increased by US$250 million the $1 billion secured term loan that it closed in July and August. According to a company press release, the additional proceeds from the loan will be used for expansion of its current business, as well as acquisitions and corporate purposes.
