Abstract	In wireless communication system, the propagation characteristics of the radio coverage areas such as indoor, outdoor, indoor-to-outdoor and outdoor-to-indoor are very important to acquire the accurate received signal strength. In this paper, the experiments are conducted for both indoor-to-outdoor and outdoor-to-indoor wireless communication environments to investigate how much the received signal strength values are different between them. To obtain the accurate received signal strength between the outdoor-to-indoor and indoor-to-outdoor areas, the COST 231 radio wave propagation model is extended by including additional path loss factors (A f ) such as the building parameters, the heights of the transmitter and receiver, the distance between the transmitter and the receiver for each scenario. The proposed received signal strength prediction models for indoor-to-outdoor and outdoor-to-indoor wireless communication are validated by comparing with the experimental and predicted the received signal strength indicator (RSSI) values. According to the comparison results, the received signal power from the outdoor to indoor communication is higher than that of indoor-to-outdoor ones about -2 dBm or -3 dBm.
