Abstract
An apparatus for linking mobile communication devices to wireless networks in underground edifices includes a plurality of base stations which are arranged at a spatial distance from one another inside tunnel systems, substantially in the direction of the tunnel axes, such that the reception areas of two adjacent base stations overlap as little as possible. All base stations operate on a single common channel. In a method used for the apparatus, the mobile station switches to an adjacent base station when a quality signal drops below a predetermined threshold value.

An apparatus for linking mobile communication devices to wireless networks in underground edifices inside a tunnel system having tunnel passages along tunnel axes and intersections, the apparatus comprising:
- a plurality of base stations,
- wherein the plurality of base stations are arranged at a spatial distance from one another inside said tunnel system substantially in the direction of the tunnel axes such that reception areas of two adjacent base stations are prevented from substantially overlapping, and the plurality of base stations are operated on a single common channel.
A method for setting up underground networks with WLAN techniques comprising at least one apparatus for linking mobile communication devices to wireless networks in underground edifices inside a tunnel system having tunnel passages along tunnel axes and intersections, the method comprising the steps of:
- providing the at least one apparatus for linking mobile communication devices to wireless networks, the apparatus comprising:
- a plurality of base stations, wherein the plurality of base stations are arranged at a spatial distance from one another inside the tunnel system substantially in the direction of the tunnel axes, such that reception areas of two adjacent base stations are prevented from substantially overlapping, and the plurality of base stations are operated on a single common channel;
- and
- at least one mobile station;
- and
- selecting the base station to be used with the mobile station to provide a connected base station on the basis of a connection quality signal.
An apparatus for linking mobile communication devices to wireless networks in underground edifices comprising:
- a plurality of base stations which are arranged at a spatial distance from one another inside tunnel systems substantially in a direction of tunnel axes,
- wherein the apparatus keeps mobile stations located within an area authenticated with a greatest possible number of base stations and the mobile stations are in each case associated with one of the plurality of base stations.
