Ad hoc communication network

12:

• An ad hoc communication network, comprising:
• at least one vehicle-side radio device connected to a vehicle for wireless communication;
• a plurality of route-side radio devices installed along a route of the vehicle for wireless communication;
• a monitoring and control unit which is connected to at least one of said route-side radio devices;
• said route-side radio devices being configured to communicate wirelessly without logical connection to other pieces of route-side radio devices located in radio range and to said vehicle-side radio device, and to forward received data to other track-side radio devices located in radio range;
• wherein said route-side radio device are arranged such that at least two other route-side radio devices in either direction along the route are in radio range of each of the route-side radio devices;
• and
• wherein said route-side radio devices are enabled to transfer received data to a next route-side radio device and the route-side radio device after the next in a direction along the route.

13:

• The ad hoc communication network according to claim 12, wherein each route-side radio device is configured:
• to communicate wirelessly with all route-side radio devices within its radio coverage area;
• and
• to transmit data received from a first route-side radio device to at least one second route-side radio device which does not lie within the radio coverage area of the first route-side radio device.

18:

• The ad hoc communication network according to claim 17, wherein each of said route-side radio devices has two transceiver units and a receiver unit, and wherein
• said receiver unit is configured for receiving data unidirectionally from a directly adjacent route-side radio device in each case, on a first radio channel;
• and
• said two transceiver units are configured for bidirectional communication with the route-side radio device after next in each case, wherein different radio channels are used for each direction for communication along the route, which radio channels differ from the first radio channel in each case;
• and
• a utilization of the at least three different radio channels per route-side radio device along the route takes place in an alternating, repeating sequence.

19:

• The ad hoc communication network according to claim 18, wherein each said route-side radio device is configured:
• to receive unidirectionally on a first channel;
• to communicate bidirectionally in a first direction along the route on a second channel that is different from the first channel;
• and
• to communicate bidirectionally in a second direction that is different from the first direction along the route on a third channel that is different from the first and second channels.

20:

• The ad hoc communication network according to claim 18, wherein:
• in a first triplet of adjacent route-side radio devices consisting of a first route-side radio device, a second route-side radio device, and a third route-side radio device, said adjacent route-side radio devices together use the first radio channel, wherein only said first route-side radio device and said third route-side radio device of said first triplet are configured to send data, while said second route-side radio device is exclusively configured to receive data;
• and
• in a second triplet of adjacent route-side radio devices, which directly follows said first triplet and which consists of said second route-side radio device, said third route-side radio device, and a fourth route-side radio device, said adjacent route-side radio devices of said second triplet together use the second radio channel, and wherein only said second route-side radio device and said fourth route-side radio device of said second triplet are configured to send data, while said third route-side radio device is exclusively configured to receive data;
• and
• in a third triplet of adjacent route-side radio devices, which directly follows said second triplet and which consists of said third route-side radio device, said fourth route-side radio device, and a fifth route-side radio device, said adjacent route-side radio devices of said third triplet together use the third radio channel, and wherein only said third route-side radio device and said fifth route-side radio device of said third triplet are configured to send data, while said fourth route-side radio device is exclusively configured to receive data.

21:

• The ad hoc communication network according to claim 18, wherein:
• a first route-side radio device is configured to receive data from its two directly adjacent route-side radio devices via the third channel by way of the receiving unit of said first route-side radio device;
• and
• a second route-side radio device, which is arranged directly adjacent said first route-side radio device in a first direction along the route, is configured to receive data from its two directly adjacent route-side radio devices via the second channel by way of the receiver unit of said second route-side radio device;
• and
• a third route-side radio device, which is arranged directly adjacent said second route-side radio device in the first direction along the route, is configured to receive data from its two directly adjacent radio devices via the first channel by way of the receiver unit said third route-side radio device.
