【 摘 要 】

This thesis focuses on the feasibility of adding a new dimension to spatial context referred to as orientation. Based on directional antennas and previous work in RSSI based radio distance estimation, this work shows that using directional antennas alone, the angle between two devices can be approximated. Furthermore, this thesisshows the effect of distance estimation error on angle estimation and how the number of samples affects the error in angle estimation.
