“Now LightSquared is trying to change the rules and repurpose it for terrestrial transmission,” said Dale Leibach, a spokesman for the industry group Coalition to Save Our GPS. “This is a problem because LightSquared made a bad gamble.”

Mr. Ahuja said his company aimed to “fundamentally transform the way in which American consumers get telecommunications services” and make a technological leap in both service quality and coverage at the same time.

The LightSquared network would be the first to integrate ground-based cellular service from radio towers across the country and satellite-based service.

The network would offer high-speed Internet and phone services “to every single American [over] every square inch of the United States,” Mr. Ahuja said.

He said the company raised $4.3 billion from investors and spent more than $1 billion building and launching its satellite and $2 billion acquiring the companies that owned the technology and the licenses it needed.

LightSquared employs 350 people at its Reston headquarters and “hundreds and hundreds” of engineers and other contractors across the country who are building the network, which Mr. Ahuja said would cost $14 billion over eight years.

He said the fourth-generation LightSquared service would offer “the kind of quality American consumers have not experienced before” in telecommunications, such as the ability to place and receive calls “through two concrete walls [or in a] moving elevator.”

He said the service will upend “an industry in which the United States has become a laggard, not a leader.” The United States ranks 17th in the world in terms of high-speed wireless penetration, “comparable to Malta or Bahrain,” he said.

“Network coverage in Mumbai is superior to that in Memphis,” he said.

He blamed an industry model in which the same companies build the networks, operate the systems, and sell the services and the handsets that receive them.

“Innovation is unleashed once the business model is changed,” he said.
