  10. NMT/G3G 1X Voice Capacity Comparison Note: NMT Figures provided by NMT MoU Digital Interest Group. The NMT figures do not include capacity increases achieved from interleaving (NMT-i)

  11. Overview of cdma2000 3G Handsets • ~20 cdma2000 1X handsets commercially available with over 20 devices to come. • Over 1.5 Million subscribers in Korea. • US Carriers have started selling 3G handsets. • Average wholesale price ~$160 USD with monochrome screen (higher pricing for color). • Data speeds up to 153 Kbps in both directions (up & downlink). • Builds on global CDMA economies of scale (450 MHz, 800 MHz, 1700 MHz, 1900 MHz, 2100 MHz).

  12. What are we to conclude? • The world needs a more “economical” 3G solution for rural coverage. • Lower frequencies are the key to reducing cost. • The 400 MHz range has multiple bands available in many countries. • We need your support to have the 400 MHz range recognized by the ITU as an identified 3G band.
