  we review the Baryon Acoustic Oscillations from Integrated Neutral Gas
Observations (BINGO) telescope, an international collaboration, led by Brazil
and China, aiming to explore the Universe history through integrated
post-reionization 21cm signals and fast radio emissions. For identifying
individually fast radio sources, the Advanced Bingo Dark Universe Studies
(ABDUS) project has been proposed and developed and will combine the current
BINGO construction with the main single-dish telescope and stations of
phased-array and outrigger.
