Through Decision-making
An Asian City Is Deploying a Metro-Wide
Wireless Mesh Network with 10000 APs
• High-speed WLAN broadband access and
new wireless services in Mass Rapid
Transportation stations, selected commercial
buildings and other key locations across the
city.
• Applications:
• Video streaming
• Video surveillance – Real time image
captured from Wi-Fi cameras or web
cameras.
• Multimedia communications.
• Outdoor mobility
Demographics: 272 sq Km with 2.65M
people
User: city staff and public
Standards: 802.11b uplinks and 11a
inter-AP links
Security: IPSec on inter-AP links and
moving to 802.11x
"With powerful business models
for government applications,
enterprises, and wireless and
wireline service providers, the
Wireless Mesh Network solution
enables delivery of secure wireless
broadband services that can
provide a cost-effective method for
extending wireless LAN coverage
more broadly into business and
end-user markets."

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:
Time to get served or provide service
The speed of light
Time to adapt to new customer needs
The human life span
Time to profitable revenues
Geoffrey A. Moore
Time to isolate new security threats
Time 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 livepresence indicator

What is SIP?
Text Book:
Session Initiation
Protocol (SIP) is a textbased signaling
protocol, for initiating
interactive
communication
sessions between
users. Such sessions
include voice, video,
chat, interactive games,
and virtual reality.
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.
