This work involves the determination of GSM signal strength level in brick, zinc, wood, mud, block and steel buildings in Ekpoma. Measurements of signal strength and its associated location parameters referenced globally were carried out. Existing works on path loss exponent values were studied to determine the extent to which building characteristics (in terms of its construction and materials) affect propagated signal. Propagation Path loss characteristics of Ekpoma were investigated using ten different environments which reflect a good representation of the town. Consequently, power received (Pr) was measured from a distance (d) from the base station for various environments investigated. The data were analyzed to determine the propagation path exponent and path loss characteristics. From calculation, the path loss exponent values were, 9.0, 10.2, 8.44, 7.0, 7.66 and 11.33dBm for brick, zinc, wood, mud, block and steel buildings respectively. Indoor propagation models were developed for the different building types considered such that the signal level in the building types considered can be approximately predicted once the transmitter-receiver (T-R) distance is known.
