DISPOSITIVO HARDWARE WIRELESS PER IL RILEVAMENTO DI RELAZIONI DI DISTANZA, E SISTEMA DI MONITORAGGIO DI RELAZIONI DI DISTANZA TRA DISPOSITIVI HARDWARE WIRELESS

摘要

Described herein is a wireless device (4), provided with: a transceiver module (14), which transmits data packets that have a transmission-power level selectable from among a number of power levels and include information of the transmission-power level, and receives data packets from surrounding devices (4); and a control unit (12), which is connected to the transceiver module (14) and controls the transmission and reception of the data packets by the transceiver module (14). The control unit (12) carries out processing operations on the data packets received from the surrounding devices (4) in a detection time interval in order to determine proximity relations between the wireless device (4) and said surrounding devices (4).
