Criminalizes use of "signal jammers."

S 450 would make it a fourth-degree crime in New Jersey to use signal jammers that block cell phone signals, GPS, or emergency communications. The bill expands existing state law to specifically prohibit interfering with radio communications licensed under federal law (such as cell networks) and using scanning receivers designed to intercept cellular transmissions. This aligns New Jersey's penalties with federal prohibitions (47 U.S.C. §§ 301 and 333), which already ban signal jamming. The law targets devices that disrupt authorized communications, including those used to block emergency services or prevent calls/texts.
