  • Patent number: 7809596
    Abstract: Provided are an apparatus for evaluating an indirect loss caused by a ubiquity effect by provision of a universal service, and a method thereof. The apparatus includes a first data storage unit for storing population statistics-related data, a second data storage unit for storing universal service offer-related data, a control unit for reading out and delivering required data from the first and second data storage units to a ubiquity loss calculation unit and controlling the ubiquity loss calculation unit, the ubiquity loss calculation unit for calculating a ubiquity loss of each evaluation object district by using the required data from the control unit, and a third data storage unit for storing the ubiquity loss of each evaluation object district calculated in the ubiquity loss calculation unit.

  • Patent number: 7286829
    Abstract: In a wireless network base station design method for selecting an optimal base station in a wireless network design system, a sample point and a candidate base station area are determined according to a predetermined reference; propagation between the sample point and the candidate base station area is analyzed and a path loss is forecast; a base station is selected in consideration of wave propagation caused by the propagation analysis; a cell shrinkage degree is determined in consideration of traffic, and propagation is re-analyzed based on the cell shrinkage degree; and a base station is selected in consideration of the wave propagation and a call volume according to the re-analysis of propagation.
