AT&T continues to hammer away at PCAST's shared spectrum vision

AT&T (NYSE:T) continues to blast last month's core recommendations from the President's Council of Advisors on Policy and Technology, which wants the new norm for U.S. spectrum use to be based on sharing rather than exclusive licensing. On AT&T's Public Policy Blog, Joan Marsh, the operator's vice president of federal regulatory, cited three broad categories of concern that the company has with PCAST's vision: Investment, technology and spectrum efficiency. Some think tanks, consumer groups and education organizations as well as white-space players have come out in support of the PCAST report. The PCAST advisory council's members include tech luminaries such as Google (NASDAQ:GOOG) Executive Chairman Eric Schmidt and Craig Mundie, chief research and strategy officer at Microsoft (NASDAQ:MSFT). AT&T's Marsh noted the council's membership did not include a wireless carrier, equipment manufacturer or chipset maker. Article
