Abstract:
1. A network planning system for determining specifications for a wireless network, comprising: an input module configured to receive traffic statistics for the wireless network; a processing module configured to receive the traffic statistics and generating the specifications for an intended network, the processing module being operative to construct a design for the intended network and generate the specifications for the intended network, the constructed design of the intended network comprising a layout of base stations and antennae configurations of the base stations, the processing module being operative to compute user level performance parameters for the intended network using a processor sharing queuing model, the processing module being operative to directly compute the user level performance parameters based on the traffic statistics and the generated network specifications, the processing module being further operative to compare the user level performance parameters against predetermined requirements and to repeatedly adjust the generated network specifications, compute new user level performance parameters and compare the user level performance parameters against the predetermined requirements until a set of generated network specifications produces user level performance parameters meeting the requirements; and an output module configured to present the network specifications generated by the processing module, wherein the generation of the network specification is performed by an optimization application existing as software executed by the processing module, wherein the optimization application includes a network specifications module configured to generate the original and adjusted intended network specifications and a user level performance module configured to compute the user level performance parameters based on the network specifications and the traffic statistics, wherein the network specifications module computes propagation parameters based on the network specifications and supplies the propagation parameters to the user level performance module for use in computing the user level performance parameters, wherein the user level performance module computes expected delay, blocking probability and throughput based on the traffic statistics and the network specifications, wherein the user level performance module is operative to select from among models for computing performance parameters for file transfer applications and models for computing performance parameters for hypertext markup language page browsing applications.
