  • Method and apparatus for dynamically updating representation of a work site and a propagation model
    Patent number: 6771609
    Abstract: The present invention includes a method for dynamically updating a propagation model of communication signals in an area being subjected to earthworking operations which alter the topology of the terrain in which the method comprises the steps of dynamically updating a terrain map of the area as a function of the earthworking operations and dynamically updating the propagation model in response to updating the terrain map.

  • Method and apparatus for incorporating environmental information for mobile communications
    Patent number: 6625135
    Abstract: An apparatus and method for communicating between a first communication node and a second communication node in an area having a plurality of communication nodes is disclosed which comprises generating a propagation model of signals from selected communication nodes in the area. The communication nodes may be fixed or mobile. The propagation model is based on an environmental map that includes the topography of the terrain and structures in the area. The propagation model is generated at selected intervals to provide updated information for predicting the quality of communication at a location at a future time.
