Some analysts have predicted that the AT&T takeover will be approved, but with the proviso that the telecom giant divest of certain network assets and move out of certain markets. Sprint's having none of that either. "This proposed takeover cannot be fixed with conditions or divestitures," McCann says. "We believe the facts and the law dictate that this transaction must be blocked, and are confident that the Department of Justice and FCC will determine that this takeover is not in the interest of the American public."

In a nutshell, in the filing that the combination of the two networks would make better use of wireless spectrum, and create "synergies" (the removal of redundant equipment and people) in the combined network that would eventually improve service. Here are some of the more interesting tidbits.

On spectrum: "The network synergies of this transaction will free up new capacity - the functional equivalent of new spectrum - in the many urban, suburban and rural wireless markets where escalating broadband usage is fast consuming existing capacity."

On "synergies": "The combined company expects to integrate a significant portion of T-Mobile cell sites into the AT&T network. Upon network integration, which will benefit customers in as little as nine months, this will equate to "instant" cell splits - increasing cell density and effectively doubling the amount of network traffic that can be carried using existing spectrum in the areas served by those cell sites." AT&T and T-Mobile both currently operate GSM/HSPA+ networks and the spectrum to match."
