Alltel claims to have America's largest mobile network... by square miles that is. The regional operator has made a bold marketing claim that is is the country's largest operator, but its disclaimer says, "Largest Network Claim: Based upon analysis by an independent research company in December 2005, which compared marketed coverage patterns at the time of their creation of each wireless carrier without allowance for variations due to electrical interference, customer equipment, topography & each carrier's translation & defined preferences of their own internal engineering data." Huh? Engadget iMobile tried to conduct some due diligence to figure out if the claims are true by comparing coverage maps, but that doesn't help much given roaming agreements. The conclusion? Alltel would probably do well to do some more explaining. Article
