A wave bubble is a self-tuning, wide bandwidth device used to jam radio frequency signals, such as Bluetooth, cellular, GPS, and Wi-Fi. A portable wave bubble runs on a lithium-ion battery that provides about two hours of continuous two-band or four hours of continuous single-band jamming. It also has a range of up to 20-feet.
Due to FCC regulations, a wave bubble device is not available in any retail or online store, so it must be built. Also, in many places, it is illegal to operate a wave bubble if it is built.
