Abstract

See full text

A method for locating a tag by a network of sensors using the IEEE 802.15.4a protocol. The reference anchor of the network sends a UWB signal comprising first beacons at regular intervals, and a narrow band signal on an auxiliary channel, comprising second beacons, the second beacons being in synchronous relation with the first beacons. The tag negotiates with a coordinator anchor, via the auxiliary channel, the allocation of an elementary interval within the UWB superframe. When an elementary interval is allocated to the tag, it places its narrow band receiver in standby mode and sends a clap message in the elementary interval.
