We calculate the spectra expected from unsteady relativistic wind models ofgamma-ray bursts, suitable for events of arbitrary duration. The spectralenergy distribution of the burst is calculated over photon energies spanningfrom eV to TeV, for a range of event durations and variability timescales. Therelative strength of the emission at different wavelengths can provide valuableinformation on the particle acceleration, radiation mechanisms and the possibletypes of models.
