Measurements of the global 21-cm signal from the Cosmic Dawn
  The sky-averaged (global) 21-cm signal is a very promising probe of the
Cosmic Dawn, when the first luminous sources were formed and started to shine
in a substantially neutral intergalactic medium. I here report on the status
and early result of the Large-Aperture Experiment to Detect the Dark Age that
focuses on observations of the global 21-cm signal in the $16 \lesssim z
\lesssim 30$ range.
