Abstract

There is provided a method for determining passage of a portable wireless transceiver device along a constrained path. The method comprises acquiring at least one time of flight (ToF) measurement and auxiliary information, the at least one ToF measurement being measured between a portable wireless transceiver device and a single network node. The network node is mounted proximate a constrained path. The method comprises determining whether the portable wireless transceiver device has passed the network node along the constrained path or not based on the at least one ToF measurement and the auxiliary information.
