Different propagation models are presented for multi-storied Quantitative models aural area, that predicts effect of wall partitions, number of floors and building layout at 2.4 GHz using IEEE802.11b wireless network. Propagation models have been developed for these two buildings based on number of floors between transmitter and receiver. These models are indoor location detection system designer which relate signal strength log of distance. The measurement shows that the standard deviation between measured and predicted path loss is 12.4124 dB for all locations in one building and as small as 8.0948 dB on same floor. And in other building it is 10.2854 dB and minimum 8.5454 dB for same floor measurements.
