With the advent in the near future of radio telescopes as LOFAR,
a new window on the high-redshift universe will be opened.
In particular, it will be possible, for the first time, to observe the
21cm signal from the diffuse Intergalactic Medium (IGM) prior to its
reionization and thus probe the "dark ages".
In this talk I will discuss about the theoretical modeling of the
reionziation process, the observability of the 21cm signal from the
diffuse IGM and the efforts ongoing within the LOFAR Epoch of Reionization working group.
