According to this article, BART officials interrupted cell service in one of their stations. I was under the impression that intentional disruption of cell service, or jamming of cell service, was a Federal No-No. Perhaps things have changed, but at one time theater owners wanted to disrupt service in order to eliminate cell phone traffic during the show. I believe that it was not allowed because A. someone might need emergency communications, and B. intentional jamming or interference of any radio service was a violation of some part of the Telecommunications Act. If all of that is still true, I am curious how BART got away with it.
