Abstract
A wireless network can be easily optimized utilizing processes according to the present invention. A simulation environment allows a network engineer to vary parameters (e.g., antenna height, tilt, and power) of a virtual model of the wireless network and observe how the changes affect coverage. Algorithms also enable hand off timing parameters for sectors in a wireless network to be optimized. One algorithm analyzes measured data regarding network coverage and regional terrain to arrive at a report containing recommended values for window size parameters (code division systems) or timing advance parameters (time division systems). Another algorithm analyzes measured data regarding network coverage to arrive at a report, containing recommended neighbor lists for each sector in the network.
