We will see that the unconditonal constants for frame expansions are of the form sqrt(B/A), where A and B are the frame bounds. We then show any frame in a real Hilbert space whose frame operator is diagonalizable has frame expansions that are 1-unconditional if and only if the sequence is an orthogonal sum of tight frames. We conclude with two possible directions to take next.
