alphadogg writes "For more than two years, the U.S. mobile industry has warned of an upcoming spectrum shortage, but two analysts at Citigroup don't buy it. AT&T, trade group CTIA and even officials with the U.S. Federal Communications Commission have talked frequently about a coming spectrum crunch, as mobile customers move to data-sucking smartphones and tablets. Smartphones use 24 times the spectrum compared to standard mobile phones, and tablets use 120 times the spectrum, FCC Chairman Julius Genachowski said in a speech on Tuesday. But Citigroup analysts Jason Bazinet and Michael Rollins questioned what has become the conventional wisdom in the mobile industry. The U.S. has plenty of spectrum for mobile broadband, but much of it is in the wrong hands, they said."
