  MAXI J1659-152 was discovered on 2010 September 25 as a new X-ray transient,
initially identified as a gamma-ray burst, but was later shown to be a new
X-ray binary with a black hole as the most likely compact object. Dips in the
X-ray light curves have revealed that MAXI J1659-152 is the shortest period
black hole candidate identified to date. Here we present the results of a large
observing campaign at radio, sub-millimeter, near-infrared (nIR), optical and
ultraviolet (UV) wavelengths. We have combined this very rich data set with the
available X-ray observations to compile a broadband picture of the evolution of
this outburst. We have performed broadband spectral modeling, demonstrating the
presence of a spectral break at radio frequencies and a relationship between
the radio spectrum and X-ray states. Also, we have determined physical
parameters of the accretion disk and put them into context with respect to the
other parameters of the binary system. Finally, we have investigated the
radio-X-ray and nIR/optical/UV-X-ray correlations up to ~3 years after the
outburst onset to examine the link between the jet and the accretion disk, and
found that there is no significant jet contribution to the nIR emission when
the source is in the soft or intermediate X-ray spectral state, consistent with
our detection of the jet break at radio frequencies during these states.
