Definitions

  • An object of the present invention is to propose a many-to-many parity communication technology based on a point-to-multipoint hierarchical network communication technology which is able to co-ordinate the participants in a mesh network, so that each participant is able to communicate, in the best possible conditions, with the other nodes participating in the network.
  • the nodes which operate in mode 2) perform only the function of operative mobile terminal station and are designed to operate in a mode called "MS mode".
  • the mobile terminal station part of a "multiple relay" mode may become operative only when the base radio station part of the same node is not busy communicating.
  • the MAC part of the overlying Mesh level (procedural management level of the mesh network) operates using a "scheduled PMP" principle based on the fact that, on a regular time basis, the assignment of each single unit by the controller node is redefined.
  • the PMP frames must occur periodically and the frame period is fixed at 20 ms so as to ensure compatibility with the PMP standard.
  • Access to the network by this terminal is conceptually transparent: it receives the downlink messages D sent from the node 7 and the base radio station of said node 7 will authorise it to transmit its data in uplink mode U only within the units assigned to it and therefore without causing interference with the other nodes 5, 6 and 8. This can be obtained as a particular example of PMP standard operation and therefore does not result in any special design of the "legacy" terminal 9.
