From Reuters: The FCC unanimously voted to seek comment on a plan that would let let satellite companies partner with other businesses seeking to build land-based networks or to lease their spectrum to other companies in a secondary market. The plan could affect about 90 MHz of spectrum held by companies such as SkyTerra, TerreStar and Globalstar.

The FCC approved an application by Harbinger Capital Partners to acquire SkyTerra in late March. Harbinger's approval allows SkyTerra to build a land-based nationwide broadband network. But Harbinger still needs FCC approval before leasing wholesale spectrum capacity to AT&T and Verizon Wireless.
