Multi-wavelength observations of jets at high and low X-ray luminosities
  I shall briefly review the observational properties of radio-emitting jets from Galactic X-ray binaries in relation with other wavebands: infrared, optical and X-ray. Special attention is paid to recent results obtained with the Spitzer Space Telescope on quiescent black holes as well as ultra-compact neutron star X-ray binaries
