    en.wikipedia.org/wiki/White_spaces_(radio)

    This frequency allocation process creates a bandplan which for technical reasons assigns white space between used radio bands or channels to avoid interference. In this case, while the frequencies are unused, they have been specifically assigned for a purpose, such as a guard band.

    Example of a radio map estimate using STORM, a transformer-based radio map estimator. Signal strength maps quantify signal strength at each location. Formally, a signal strength map can be seen as a function γ ( r ) {\displaystyle \gamma (\mathbf {r} )} that provides a signal strength metric for each location r {\displaystyle \mathbf {r} } .

    In the Americas (defined as International Telecommunication Union (ITU) region 2), the FM broadcast band consists of 101 channels, each 200 kHz wide, in the frequency range from 87.8 to 108.0 MHz, with "center frequencies" running from 87.9 MHz to 107.9 MHz. For most purposes an FM station is associated with its center frequency.

  9. Coverage map - Wikipedia

    en.wikipedia.org/wiki/Coverage_map

    A coverage map may be produced to indicate the area in which a certain signal strength is delivered. [1] Even if it is 100% accurate (which it never is), a major factor on whether a signal is receivable depends very much on whether the receiving apparatus is sensitive enough to use a signal of that level.
