Wireless Broadband isn’t easybut it can be done!
Data rate depends on signal qualitySignal quality impacted by many factors
• Propagation loss over distance• Delay spread (freq selective fading)• Doppler spread (time selective fading)• Angle spread (space selective fading)• Interference (self, users in sector, users in
other sectors)
16e uses advanced techniques to maximize signal quality
• OFDMA• Diversity / Opportunistic scheduling• Beamforming / SM• STC / SM

Staged Product Development Strategy
Stage 1 Stage 2 Stage 3
Stage 1 • Develop separate baseband and RF chipset
• Architect the solution for flexibility for standards fluidity and worldwide implementation• Hardware/ software partitioning for optimum power and cost but allow for in field upgrade of
critical algorithms • Reduce development risk elsewhere e.g. Fab
Stage 2• Integration of WiMAX functionality
• SiP vs SoC ?• Tradeoffs between TTM, power consumption, footprint, cost
• What is optimal BOM?Stage 3
• Integration with other technologies• WiFi?• Cellular• Bluetooth?
