摘要

无线通信中的天线发射功率、高度、角度和信号频率等因素对其接收信号强度(received signal strength indication,RSSI)有很大的影响.通过大量的实验，分析探讨室内环境下天线高度对RSSI和测距精度的影响.实验结果证明，只要选择合适的天线高度，433 MHz无线信号用于室内测距是可行的.

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)
