Radio Interference is a phenomenon in Final Fantasy VIII that has made the use of radio waves nearly obsolete by the time of the game's start.
It is a phenomenon beginning with Esthar's silence 17 years before game events. Almost all radio communication facilities were shut down because of noise across all frequencies, although short transmissions were still possible. At the time it was believed to have some relation to the moon, but details were unknown.
Although most countries in the world of Final Fantasy VIII began to communicate through the use of underground HD cables, many of these cables are cut off by monsters or due to various skirmishes and battles. Due to this many countries are left without proper means of communicating with each other.
The reason for the interference is Sorceress Adel's tomb, which, orbiting the planet, interferes with the radio waves and fills all frequencies with noise which led to most wireless technology being abandoned, and facilities, such as the Communications Tower in Dollet and the TV Station in Timber, fell to disuse. An outdoor TV display in Timber displays the interference, and one can decipher a message from Adel among the noise.
Because radio technology has largely been abandoned making live broadcasts has been difficult. When Galbadian president Vinzer Deling wants to broadcast Sorceress Edea's ascension as the nation's new ambassador, he invades the Communications Tower in Dollet to make the broadcast. While grainy, the broadcast is a success, until it is interrupted by Seifer Almasy.
Electromagnetic interference (or EMI, also called radio-frequency interference or RFI when in radio frequency) is disturbance that affects an electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.
