ABSTRACT:
A computer system generates constraint matrices for planning a cellular, wireless telephone network. A given number of specified carrier frequencies are allocated to plural radio base stations having specified positions and transmission powers. The stations act as a server cell or an interfering cell in a service zone. The computer: (1) predicts the field strength C of a field received in a mesh in the service zone at one of the server cell predetermined frequencies; (2) computes (a) for each of the meshes, the strength I of the interference field generated by the interfering cells, and (b) C/I for the “server” cell provided I of an interfering field received in the mesh is larger than a predetermined value; and (3) determines a global interference proportion tbijwhich is displayed or stored in a constraint matrix by integrating C/I over the entire service zone.
