Abstract
In this paper, we present an algorithm about distance calculation based on RSSI of RF. To calculate value of RSSI according to the classic model of signal attenuation, Radio propagation path loss model and formula of received signal strength, establish the relationship chart between the distance and RSSI value. And through the wireless module CC2430 of ETC system for real-time data collection. Compared with the theoretical data and the measured data. Do the correction through calibration model. Resulting more perfect algorithm about distance calculation.
