c|net - A small Florida company is taking on the Federal Communications Commission to change regulations prohibiting the sale of equipment used to scramble cell phone signals to local and state agencies. The company, CellAntenna, filed a lawsuit in the U.S. Court of Appeals in the 11th Circuit in Atlanta on November 22 challenging the Communications Act of 1934, which is enforced by the FCC. The 1934 act and the FCC regulations that go along with it prohibit the use of cellular and radio frequency-jamming equipment, except by federal agencies. This means that local and state officials are not permitted to use such equipment, which could be used to help prevent terrorist attacks. CellAntenna argues that the Communications Act and the FCC regulations that interpret the law are unconstitutional because they are in conflict with the Homeland Security Act of 2002, adopted by Congress in the wake of the September 11, 2001, terrorist attacks.
