    abstract = {Interest involves the determination of G.S.M signal strength in Mud, Block and Steel buildings in Ekpoma. Existing path loss exponent values were studied to determine the extent to which building characteristics (in terms of its construction and materials) affect propagated signal. Measurements of signal level taken at different building type were recorded to determine the path loss exponent values, which were 7.33, 8.33 and 12.67dBm for Mud, Block and Steel buildings respectively. A model was statistically developed for each of the building considered such that the signal level in the building can be approximately predicated once the Transmitter-Receiver (T-R) distance is known. The values obtained by the developed models were in the range of the measured values.}
