Ocelot is a Lucent tool for modeling the performance of cellular networks, and optimizing that predicted performance with respect to antenna parameters, such as azimuth, pilot fraction, and tilt. For Ocelot to be useful, its numerical model must satisfy some stringent requirements: simple enough to compute quickly, smooth enough to optimize effectively, and accurate enough to given meaningful results. As well as an overview of Ocelot, this talk will describe one or two specific aspects of its modeling; for example, Ocelot estimates the effect of dynamic shadow fading on active-set membership using a simple steady-state approximation, where more typically such effects would be modeled by simulation. The applicability of this approximation has been confirmed by computational studies.
