Abstract: Transmitted power, length and angle of antenna, and signal frequency have much impact on the variation of received signal strength indication (RSSI). By a large number of experiments in indoor environment, the influence of the antenna height on the RSSI and the ranging accuracy is analyzed. The results show that it is feasible for indoor ranging using 433 MHz wireless signal when the appropriate antenna height is selected.

Key words: antenna height, ranging based on received signal strength indication (RSSI), wireless sensor network(WSN)
