Mobile: Mobile jammers transmit signals on the same frequency as cell-phones, which blocks cellular service and prevents the mobile device from making calls or sending text messages. If a mobile jammer is operating, your cell phone won't display a network signal.
WiFi: WiFi jammers will create noise to block a WiFi connection and prevent people with a wifi-enabled device from connecting to a 3G, 4G, GPRS, or cordless WiFi network.
GPS: A GPS jammer is used to block satellites or spy devices in the 1500-1600 MHz range. It's often used to deflect surveillance or spying.
