Abstract

A telecommunications system comprises a number of remote subnetworks, a subnetwork comprising at least one tactical radio node NRT serving as gateway between said subnetwork and a backbone network consisting of at least one airborne communication node. An NRT node communicates with the airborne communication node by converting the wave form of the signals to be transmitted outside the subnetwork being associated with it into a wave form used by the airborne communication node, said airborne communication node transmitting the duly received signal without modifying its wave form to at least one NRT node belonging to another subnetwork. A tactical radio communication node and an airborne communication node are also disclosed.

Claims

1. A telecommunications system comprising a number of remote subnetworks, a subnetwork comprising at least one tactical radio node NRT serving as gateway between said subnetwork and a backbone network comprising at least one airborne communication node, wherein an NRT node communicates with the airborne communication node by converting the wave form of the signals to be transmitted outside the subnetwork being associated with it into a wave form used by the airborne communication node, said airborne communication node transmitting the duly received signal without modifying its wave form to at least one NRT node belonging to another subnetwork.

2. The system as claimed in claim 1, wherein the backbone network comprises at least one satellite, the airborne communication node transmitting the signals received from NRT nodes to said satellite and transmitting the signals received from the satellite to the NRT nodes.

3. The system as claimed in claim 2, wherein the wave form used between an NRT node and an airborne communication node is the same as the one used between an airborne communication node and a satellite of the system.

4. A tactical radio node NRT associated with a subnetwork further comprising means for transmitting and receiving data between a subnetwork and an airborne communication node belonging to a backbone network by converting the wave form of the signals to be transmitted outside the subnetwork being associated with it into a wave form used by the airborne communication node, the reverse conversion also being supported by said node.

5. An airborne communication node, further comprising means for transmitting data from an NRT node associated with a subnetwork to an NRT node associated with another subnetwork, said transmission being performed without modifying the wave form of the signals transmitted.

7. The airborne communication node as claimed in claim 5, further comprising a network controller NC responsible for allocating radio resources to the NRT nodes.

6. An airborne communication node further comprising means for transmitting data from the NRT node belonging to a subnetwork to a satellite, said transmission being performed without modifying the wave form of the signals transmitted.
