Reradiation

In telecommunications, the term reradiation has the following meanings:

1. Electromagnetic radiation, at the same or different wavelengths, i.e., frequencies, of energy received from an incident wave.
2. Undesirable radiation of signals locally generated in a radio receiver. This type of radiation might cause interference or reveal the location of the device.

Near-field effects of an AM antenna may extend out Template:Convert or more. Cellular and microwave towers within this radius can reflect the Medium Wave AM signal out at a phase which cancels the main Medium Wave AM signal. This process results in an interfering signal called reradiation.<ref>Detuning Communications Towers Solves Reradiation Problem: Technical Note 102</ref> Template:FS1037C MS188
