/**
 * The Unit Disk Graph medium has two different range parameters; one for
 * transmitting and one for interfering other transmissions.
 *
 * The radio medium supports both byte and packet radios.
 *
 * The radio medium registers a visualizer plugin. Via this plugin the current
 * radio states and range parameters can be viewed and changed.
 *
 * The registered radios' signal strengths are updated whenever the radio medium
 * changes. There are three fixed levels: no surrounding traffic heard, noise
 * heard and data heard.
 *
 * The radio output power indicator (0-100) is used in a very simple way; the
 * total transmission (and interfering) range is multiplied with [power_ind]%.
