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)

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

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.
