Criminalizes the use of "signal jammers."

This bill (A3739) makes it a fourth-degree crime in New Jersey to use devices that block or interfere with wireless communications, such as cell phones, Wi-Fi, GPS, or emergency services. It directly affects anyone using "signal jammers" (also called signal blockers or cell phone jammers), which prevent calls, texts, or emergency location signals. The law updates existing state law to explicitly prohibit interfering with radio communications licensed under federal law, including blocking cellular frequencies or using modified scanning receivers. These devices are already illegal under federal law, but this bill strengthens state enforcement by adding specific language to criminalize their use. The key provision ensures that jamming technology cannot disrupt public safety communications or commercial services.
