1. An apparatus comprising:
- locating objects that are arranged in a confined space and are able to be moved, each locating objects emitting pulsed radio signals, andat least three reference nodes that are operating communication-technically autarkic, spatially distributed and form a communication network segment arranged in the confined space,wherein the at least three reference nodes are arranged or formed to be communication-technically linked,wherein the at least three reference nodes and the locating objects are managed with communication technology,wherein at least one locating object is able to be located by a distance-based trilateration that is carried out by the at least three reference nodes,wherein a locating object newly registering in the communication network segment listens to a broadcast communication in the communication network segment via a first communication channel in order to receive an overview of the at least three reference nodes present in the communication network segment, and the locating object communicates asynchronously with a reference node of the at least three reference nodes selected from the broadcast communication via a second communication channel, in order to cause the reception of the locating object in the communication network segment, andwherein the selected reference node allocates a preliminary code to the locating object and provides global information about the network topology.

Abstract
In a network arrangement for carrying out a location of locating objects that are arranged in a confined space and are able to be moved, the location being carried out by pulsed radio signals, wherein at least three communication-technically autarkic reference nodes that are spatially distributed and form a communication network are arranged in the confined space a communication protocol enables a location object that is arranged in the confined space to be localized by a trilateration carried out by a distance-based trilateration that is carried out by the at least three reference nodes.
