"A U.S. trade group representing wireless telephone service providers has asked the U.S. Federal Communication Commission (FCC) to continue its ban on cell-phone calls during airplane flights, saying those calls could interfere with other wireless calls. The Cellular Telecommunications & Internet Association (CTIA) on Thursday filed comments with the FCC saying the agency should hold off on its effort to approve the use of wireless phones during flights because no solution exists for the interference problem. In December, the FCC began a proceeding to consider allowing airborne wireless calls on 800MHz phones, as long as such calls didn't interfere with ground-to-ground wireless traffic."
A debate that just will not die continues. With two US government agencies involved here (FCC and FAA, both of which are just now entering the bronze age) I wouldn't worry too much about anything happening very soon. I think underneath all of this banter about interference with airplane radios and ground cell phone users is the terror of a small room full of people all on their phones at once.
