    In this paper we describe an overhauled, robust approach for spectrum occupancy evaluations (SOE) at industrial, scientific and medical (ISM) band in a hospital environment for interference free, dynamic spectrum access (DSA). A novel bandwidth and center frequency estimation algorithm is presented in order to distinguish among various coexisting systems. Different results are inferred by processing data obtained from a day long measurement campaign including channel occupancies, frequency band occupancy, and spectrum resource occupancies.
