About this interactive

Jamming denies availability by drowning out radio signals, and the lesson's key point is the reach of the attack: it affects anything that communicates through the air, because waves interfere with waves. Wi-Fi, Bluetooth, cellular and GPS are all airborne, so all are in range of a jammer. What a jammer cannot reach is a signal carried on a wire or fibre. Traffic on an Ethernet cable, a fibre uplink, a copper link between servers, or a device reading its own local storage never crosses the air, so no amount of radio noise disrupts it. The defender's takeaway is which assets lose availability to a jammer and which do not: a site whose only uplink is cellular or Wi-Fi is exposed, while the same traffic on a wired path is not.
