A Short History Lesson on Public Wireless with
1.3B Users Globally

• In the beginning was AMPS (34M users)
• Advanced Mobile Phone System 1970s technology
• TDMA was the next step (120M users)
• No path to high speed data beyond GPRS
• CDMA (164M users globally- mostly in Americas)
• 2G Code Division Multiple Access- variants using
  pure packet mode
• Moving to 2.5G CDMA2000 (1X at 50 Kbps)
• Moving to 3G (1xEV-DO up to 2.4 Mbps)
• GSM (870M users)
• Global System for Mobile Communications using
  time slot assignment
• Evolving to 2G GPRS (General Packet Radio
  Service) typically 40Kbps
• 2.5G Enhanced Data rate for GSM Evolution (EDGE)
  building on GPRS up to 384Kbps and ultimately 3G
  UMTS (based on W-CDMA)
• Some Canadian TDMA carriers jumping onto the GSM
  wave

Its About Time

• An organization's ability to learn, and
  translate that learning into action rapidly, is
  the ultimate competitive business
  advantage.Jack Welch, General Electric
• Almost three-quarters of the top IT executives
  surveyed say speed to market is critical in their
  industry.
• CIO Insight's July03 research on the real-time
  enterprise
• There are two critical resources in life
• The speed of light
• The human life span
