Comparative analysis between 2.4-GHz and 868-MHz technologies. Floor map of the indoor environment (third floor of DEIB building, Politecnico di Milano). Links corresponding to green positions are characterized by a partially obstructed LOS; links corresponding to red positions suffer from severe NLOS. The position of the AP is indicated by a triangular marker; rectangular and circular markers refer to the 868-MHz and the 2.4-GHz co-located devices, respectively.
