Förfarande och anordning för att prediktera signalegenskaperna i ett trådlöst kommunikationssystem

摘要

The apparatus includes a memory for storing representations of a microcellular transmitter and a macrocellular transmitter. The representation of the microcellular transmitter is configured to transmit a representation of a first signal, the representation of the macrocellular transmitter is configured to transmit a representation of a second signal. A database is responsive to the memory. The database has a plurality of data structures, and the plurality of data structures comprise a map of a geographic area. A predetermined location is positioned on the map. A facet having a size and comprising at least three points defining a plane is associated with the predetermined location. First and second instruction sets are available to calculate a characteristic of the first and second signals. A processor responsive to the memory and the database uses one of the first instruction set and the second instruction set to calculate the characteristic at the predetermined location.
