  We report on studies of two-particle \Delta\eta\Delta\phi\ angular
correlations measured in proton-proton collisions at center of mass energies
sqrt{s} = 0.9 TeV, sqrt{s} = 2.76 TeV and sqrt{s} = 7 TeV registered by the
ALICE experiment at LHC. We present the dependence of the correlation function
on the pair transverse momentum, the multiplicity of the event and the charge
combination of particles in the pair. \Delta\eta\Delta\phi correlations are
expected to exhibit several structures which arise from different physics
mechanisms. The results are also related to the correlations obtained by
femtoscopic analysis. We show that the minijet hypothesis for the
non-femtoscopic underlying correlation should be taken into account while
performing the femtoscopy analysis.
