A Short History Lesson on Public Wireless with 1.3B Users Globally
> In the beginning was AMPS (34M users) > Advanced Mobile Phone System: 1970’s 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

What’s The Killer App?
Unified Communications… anytime, anywhere, anyhow
It’s 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 lightThe human life span
Geoffrey A. Moore
Time to get served or provide serviceTime to adapt to new customer needsTime to profitable revenuesTime to isolate new security threatsTime to recover when things go wrong

Unified Communications
Communication markets converging to form UC:
• Voice messaging and unified messaging
• Live voice, such as private branch exchanges (PBXs) — call handling
• E-mail • Voice, Web and video
conferencing, and collaboration • Instant messaging (IM) and live-
presence indicator

What is SIP?
Nortel Networks:
SIP-driven converged communications connects users over any device, utilizing individual preferences to eliminate access barriers, and provide real-time network and application awareness that improve productivity and streamline business processes.
Text Book:
Session Initiation Protocol (SIP) is a text-based signaling protocol, for initiating interactive communication sessions between users. Such sessions include voice, video, chat, interactive games, and virtual reality.
