This document discusses a phased approach to evaluation in the IEEE C802.20-04/04 group call. Three phases progressively build sophistication to ensure fair proposal comparisons and assess air interface performance. A structured way is proposed to gather data and metrics, from system-level to higher-layer impact, leading to a complete end-to-end model.
E N D
Phased Approach • Discussed on evaluation group call • Propose three phased approach to evaluation • Progressively build sophistication in each phase • Benefits • Ensures progressive “apples to apples” comparisons between proposals • Obtain early view of air interface performance without data overload
Phased Approach • Details to be determined by evaluation group • For example, build sophistication progressively in structured way • First phase, key system level performance metrics are gathered with simplified traffic, channel, and network models. • Traffic model: simplified, eg. hungry user • Channel model: simplified, eg. one model • Network model: simplified eg. No network delay • Second phase impact of air interface on higher layers incorporated • Traffic model: extended eg. ftp or http • Channel model: extended eg. A few models • Network model: simplified • Third phase: complete end to end model
