In most of particle dark matter (DM) models, the DM candidate injects sizable
fluxes of high-energy electrons and positrons through its annihilations or
decays. Emitted in regions with magnetic field, they in turn give raise to a
synchrotron radiation, which typically covers radio and infrared bands. We
discuss the possibility of detecting signatures of Galactic and extra-galactic
DM in the total intensity and small-scale anisotropies of the radio background.
