Summary

Descripción general del contenido del recurso.

"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." "Hay una abundante literatura acerca de sistemas de posicionamiento usando señales de WiFi. La gran mayoría de los sistemas con hardware comercial no específico, utilizan mediciones de RSSI. En este artículo, intentamos determinar cuál es la máxima exactitud de este tipo de sistemas. En vez de realizar un análisis teórico, por ej., con cotas del estilo de Crámer-Rao o Ziv-Zakai, aplicamos el estado del arte en algoritmos de localización a mediciones propias realizadas en condiciones experimentales bien controladas. A partir de este trabajo, concluimos que es difícil obtener una exactitud menor a 1 metro."
