WASHINGTON — A proposed wireless broadband network that would provide voice and Internet service using airwaves once reserved for satellite-telephone transmissions should be shelved because it interferes with GPS technology, the Federal Communications Commission said Tuesday.

The F.C.C. statement revokes the conditional approval for the network given last year. It comes after an opinion by the National Telecommunications and Information Administration, which said that “there is no practical way to mitigate the potential interference at this time” with GPS devices. The telecommunications and information agency oversees telecommunications policy at the Commerce Department.

The news appears to squash the near-term hopes for the network pushed by LightSquared, a Virginia company that is majority-owned by Philip Falcone, a New York hedge fund manager.

LightSquared said on Tuesday that the testing of the network was “severely flawed.” It “remains committed to finding a resolution with the federal government and the GPS industry to resolve all remaining concerns,” the company said in a statement.
