The authors study scalable frames and introduce piecewise scalable frames using projections in the paper. Some results regarding piecewise scalable frames are obtained. A few results characterizing these frames in terms of unitary operators are given. A result for piecewise scalable frames is extended to the tensor product of spaces.
