  Recently, various observational data predict a possibility that inflation may
naturally occur in a warm region. In this scenario, radiation is produced
during the inflation epoch and reheating is avoided. The main question arises
that what is the origin of warm inflation in 4D universe? We answer to this
question in brane-antibrane system. We propose a model that allows all
cosmological parameters like the scale factor a, the Hubble parameter H and
phantom energy density depend on the equation of state parameter in transverse
dimension between two branes. Thus, an enhancement in these parameters can be a
signature of some evolutions in extra dimension. In our model, the expansion of
4D universe is controlled by the separation distance between branes and evolves
from non-phantom phase to phantom one. Consequently, phantom-dominated era of
the universe accelerates and ends up in big-rip singularity. Also, we show that
as the tachyon potential increases, the effect of interaction between branes on
the 4D universe expansion becomes systematically more effective, because at
higher energies there exists more channels for flowing energy from extra
dimension to other four dimensions. Finally, we test our model against WMAP and
Planck data and obtain the ripping time. According to experimental data,
$N\simeq 50$ case leads to $n_{s}\simeq 0.96$, where \emph{N} and $n_{s}$ are
the number e-folds and the spectral index respectively. This standard case may
be found in $0.01 < R_{Tensor-scalar } < 0.22$, where $R_{Tensor-scalar }$ is
the tensor-scalar ratio. At this point, the finite time that Big Rip
singularity occurs is $t_{rip}=33(Gyr)$.
