This paper addresses offline modeling for coverage and load evaluation in code-division multiple-access (CDMA) networks, where demand may exceed capacity. We introduce the offline problem of allocating transmission power to spatial snapshots of users, given their priority for admission to a network. Such network evaluation allows us to assess whether a current or potential network configuration can provide adequate physical-layer resources for a specific snapshot of users at a particular point in time. This may be reapplied many times with different snapshots of the user location and different requests for services. We introduce a new heuristic approach that substantially reduces computational complexity for the problem. We benchmark the algorithms by comparison with the simulation of online power control.
