  We present detailed predictions for the redshifted 21cm signal from the epoch
of reionization. These predictions are obtained from radiative transfer
calculations on the results of large scale (100/h Mpc), high dynamic range,
cosmological simulations. We consider several scenarios for the reionization
history, of both early and extended reionization. From the simulations we
construct and analyze a range of observational characteristics, from the global
signal, via detailed images and spectra, to statistical representations of rms
fluctuations, angular power spectra, and probability distribution functions to
characterize the non-gaussianity of the 21cm signal. (abbreviated abstract)
