3. 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

4. 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
