Globalstar, Inc.(NYSEMKT:GSAT) rose in early trading following favorable comments by Jim Cramer on CNBC. The stock pundit described the satellite phone company as “the mother of all speculative” stocks because it has more than doubled this year while posting losses.

Cramer said the company is potentially more valuable because of its rights to airwaves that could be used for WiFi service. The spectrum could be valuable to telecommunications, cable and Internet companies, he said. Globalstar has asked the Federal Communications Commission for permission to use its spectrum for WiFi.

“Currently the request is under review,” Cramer said, “but because the request hasn’t raised any serious opposition, I think it’s extremely likely that they get a favorable ruling.”

Globalstar gained 5.7% in early trading to $4.44 a share. The company reached a six-year high of $4.42 during regular trading on June 13.

Ascent Solar Technologies, Inc. (NASDAQ:ASTI) gained in early trading after saying its solar panels will be used in a space research program. The maker of flexible thin-film photovoltaic modules was selected by Vanguard Space Technologies for its small-business innovative research program, according to a statement.

The program is intended to develop an economical, lightweight alternative to existing and emerging high-cost solar arrays for high-power space applications, the statement said. Ascent gained 18% to $0.52 a share in early trading. It reached an all-time low of $0.33 during regular trading on May 16.
