In this paper, we provide a characterization of a lower N-weighted Ricci curvature bound for N is an element of]-infinity, 1] boolean OR [n, +infinity] with epsilon-range introduced by Lu-Minguzzi-Ohta [Comparison theorems on weighted Finsler manifolds and space-times with epsilon-range, Anal. Geom. Metr. Spaces 10(1) (2022) 1-30] in terms of a convexity of entropies over Wasserstein space. We further derive various interpolation inequalities and functional inequalities.
