Goals of System Level Model
• Provide quantitative proof of WiMAX superiority
• Carriers need:
– Capacity Planning
– Performance Optimization
– Operational Guidelines
• Users need:
– Operational Guidelines
• Vendors need:
– Performance impact of various features
⇒ Develop a system level simulation methodology and
simulation package for application performance analysis
• Consists of three related projects
– System Level Simulation Methodology
– Physical Layer Model Library
– System-Level NS-2 Simulator
