Observer-frame spectrum of a $\rm 4\times 10^{12} L_{\odot}$ galaxy with increasing redshifts from $z$=0.3 to 12. The figure is based on the observed spectrum of M82 including the ISO spectral data and all available radio- and submillimeter data, and assumes a cosmology with $H_o = 50$ km s$^{-1}$ Mpc$^{-1}$, $\Omega_0=0.3$ and $\Omega_\Lambda=0.7$ (Beelen \& Cox 2001, in preparation). The strongest emission line is the [C~II] fine-structure line at 158~$\mu$m. The positions of the ALMA Bands are shown at the bottom. The thick dashed curves are 5 sigma detection limits after 1 hour of integration time.
