| Popis: | 104 This study proposes a method, that people just hold mobile device which can received signal strength indicator (RSSI) of GSM, Then, based on RSSI reduction suffered by rain, the method can estimate rain rate in mobile device location, even the environment of location is no weather station. In the past research, some of them use rain rate to compensate rain attenuation of RSSI. The other research use rain attenuation of RSSI with the distance between base station and mobile device to estimate rain rate. In this study, we only use the RSSI measured by mobile device to estimate rain rate different from other research. This study is able to make up inadequate of density form weather stations. Reduce estimation error of rain rate in no weather stations environment. So people can know rain rate of their area and prevent disaster by rain rate. People can reduce the damage and protect their lives from the disaster of rain rate. |
