Abstract
Techniques for determination of network parameters in, e.g., a processor-implemented system for characterizing, adjusting or optimizing the performance of a wireless network. In an illustrative embodiment, values of one or more link parameters of the wireless network are interpolated along edges in a mesh of data points derived at least in part from road location data characterizing an area serviced by the wireless network. A measure of network performance, e.g., a coverage measure based on pilot signal-to-interference ratio, may be generated using the interpolated values. The edges of the mesh have associated therewith a set of edge weights representative of traffic in the wireless network. The edge weights may be adjusted so as to be in agreement with available network traffic data. Interpolating between the data points of the road-based mesh permits the network performance measure to be computed as a smooth, differentiable function of the one or more link parameters, thereby simplifying network characterization, adjustment and optimization.
