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 tbij which is displayed or stored in
a constraint matrix by integrating C/I over the entire service zone.
