Here we are just interested in RSSI based localization systems. In particular, we focus on analyzing diverse system parameters, like radio base frequency, transmitting power, or modulation format, to improve the expressiveness of RSSI values. Hence, we built a real-world testbed based on sensor nodes equipped with CC1100 radio for investigating several radio configurations. Our results show that outdoor localization complies with wave propagation theory, but calibration of the radio hardware is mandatory. However, for indoor usage more knowledge about environmental effects has to be regarded to get more robust and persistent distance measurements the basis for localization. An outlook on our further research closes this paper.
