In the talk we shall discuss the behavior of fusion frames under operators with closed range. We also get conditions on a fusion frame W_u and a bounded linear operator with closed range U:H→ K, such that UW_u={(CL(UW_i) , v_i)}_{i ∈ I} is a fusion frame for K. Furthermore we show that every fusion frame
W_u={(W_i, v_i)}_{i ∈ I} of a Hilbert space H, is the image of the orthonormal fusion basis of H under a bounded surjective operator.
