Abstract
In order to determine the spatial position of a device (D), the device receives position data relating to a plurality of transmitters (T, . . . , Tn) in the area surrounding the device, each of which transmitters emits its own position data in the form of radio signals (PS, . . . , PS j). The device uses the received position data relating to at least some of these transmitters to determine its own position. The transmitters are parts of a plurality of second communication devices (T, . . . , Tn) each having at least two radio interfaces (RI, RI) of a first type (RI) and of a second type (RI) in a network (N) of a plurality of first communication devices (AP, . . . , APm) each having at least one radio interface of the second type (RI), wherein the network is switched via the radio interfaces of the second type (RI). At least some of the first and second communication devices are set up to emit first signals (BS, . . . , BSk) via the radio interfaces of the second type (RI).
