Techniques and systems for designing a network providing communication and
location identification services are described. A solution point
comprising parameters for each of a plurality of base stations is
generated. A coverage and locatability performance value for the solution
point is computed, as well as derivatives of the performance value. The
coverage and locatability performance value and its derivatives are used
to indicate favorable directions for searching for subsequent solution
points, and subsequent solution points are generated and compared against
previous solution points until an optimum solution point is found. The
coverage and locatability performance value is a weighted sum of coverage
and locatability values for each point in the service area of the
network, with coverage values representing forward and reverse link
quality and locatability values representing the probability that a point
will experience an acceptable power level from at least four base
stations.
