Ponencia en Congreso Indoor positioning based on RSSI of WiFi signals: how accurate can it be?(2019-02-20) Grisales Campeón, Juan Pablo; López, Sebastián; de Jesús Meleán, Sergio R.; Parisi, Daniel; Fierens, Pablo Ignacio; Moldovan, Herman"There is abundant literature on positioning systems based on WiFi signals. Most of the systems with off-the-shelf hardware use RSSI measurements. In this paper, we try to determine the highest achievable accuracy of such systems. Instead of resorting to a theoretical analysis, e.g., Cram´er-Rao or Ziv-Zakai bounds, we apply state-of-the-art localization algorithms to measurements in a well-controlled experimental setup. We conclude that an accuracy of less than 1 meter seems unrealistic."
