doc.: IEEE /484r0 Submission November, 2003 Julien Ryckaert / Bart Van Poucke, IMECSlide 8 Conclusion: Need for a new wireless Standard! No standard meets the requirements for wireless communication at ultra-low power for low and scalable data rate in short-range. New approach for the channel modeling is required Optimization for ultra-low power rather than for high data rate  Review of the tradeoffs  New standard required
