Clearwire, which is 54 percent owned by Sprint Nextel
It is considering an equity investment from a strategic partner like Sprint and a sale of wireless airwaves that it does not need for its service.
Prusch said the company is half way though a spectrum auction and has had interest from several partners who are doing due diligence.
We would be looking to find up to $2 billion from a sale, Prusch told reporters after his presentation at a UBS investor conference, adding that it was still not clear if Clearwire would look for both equity funding and a spectrum sale.
The question is whether we close either or both, Prusch said.
