Radionics


 * Radionics is an ancient system of communication. It utilizes electromagnetic waves to communicate from one radionics set to another.  The broadband transmitter is not encryptable, but few people use the set due to its limited range.


 * Since radionics uses electromagnetic radiation, it is limited to speed of light travel, which is another reason the HoloNet replaced it. Lando Calrissian used a radionics set to communicate with Tendra Rissant while he was in the Corellian System with Luke Skywalker.
