It is also unlawful to advertise, sell, distribute, import, or otherwise market jamming devices to consumers in the United States.
Do schools use cell phone jammers?
Despite the presence of many websites actively selling “cell jammers” or “signal blockers” to disrupt cellular communications and create impromptu “quiet zones” in cars, schools, theaters, restaurants, and other places, the use of these devices is indeed a violation of federal law.
What is RF jamming?
Definition(s): A threat in which an adversary introduces a powerful RF signal to overwhelm the spectrum being used by the system, thus denying service to all wireless nodes within range of the interference. RF jamming is classified as a DoS attack.
Can security cameras be jammed?
Any security camera can be jammed when its wireless signal is overpowered on the same frequency by a stronger signal. A Wired Security Camera can be jammed via tampering with the wire or connected equipment.
Can you jam a jammer?

Can a Bluetooth signal be jammed?
Yes, you can jam Bluetooth signals. This makes them have their signal that helps you not interfere with other modern technologies in the devices. Furthermore, Bluetooth signal utilizes a technique known as the spread-spectrum frequency that changes the channel. This leaves loopholes for Bluetooth jamming.
