Workshop
Introduction: 3G CDMA in Context (1:00
- 1:15 pm)
David G. Michelson (UBC)
Migration to third generation wireless networks presents
both opportunities and challenges for the wireless community. This workshop
provides an opportunity for wireless professionals to enhance their understanding
of both the technical aspects of 3G CDMA, and the important technical
and business issues faced by standards organizations, developers, manufacturers,
operators, and users.
3G
CDMA - An Operator's Perspective (1:15
- 1:45 pm)
David T. Shimozawa (Telus
Mobility)
The development of third generation
wireless systems has been driven by a desire to provide greater voice capacity,
higher data rates, and enhanced multimedia capabilities compared to existing
second generation networks. However, the success of third generation
wireless systems will ultimately be measured by the ability of Operators
to use them to generate revenue and gain market share. Skillful marketing
of the new capabilities and services offered by 3G systems is not sufficient.
Wireless systems evolve over time and Operators must continually review
alternative technologies, alternative migration and evolution paths, and
the marketing strategies of competitors.
Diversity
in 3G Wireless - Wideband and Multicarrier CDMA Compared (1:45
- 2:45 pm)
Rodger E. Ziemer (University
of Colorado, Colorado Springs)
Third generation wireless communications
standards include several options or radio transmission technology (RTT)
recommendations. A main one is wideband code-division multiple access (CDMA)
and one alternative is multicarrier spread spectrum. Multiple RTTs are
included in the standard for various reasons, including realization of
diversity, multiple access, and multiple rate while allowing for retrofitting
into frequency spectrum formerly occupied by second generation systems.
It is the purpose of this talk to briefly describe the two RTT options
mentioned here, wideband CDMA and multicarrier spread spectrum, and compare
their performances in fading channels typical of 3G wireless applications.
Break (2:45 - 3:00 pm)
Evolving
to 3G CDMA: cdma2000 vs. W-CDMA (3:00
- 4:00 pm)
Roman Nemish (Nortel Networks)
Although the air-interface components
of the cdma2000 and UMTS standards are both based on CDMA technology and
support similar features, the Access and the Core Networks are quite different.
cdma2000 is an evolution of the IS-95 air-interface and network, whereas
UMTS is a new air-interface and an evolution of the GSM network. Both air-interface
systems have been developed to meet the third generation requirements with
respect to improved capacity and coverage, introduction of wide range of
multimedia services, support of high data rate applications, controlled
QoS, and support of future technologies such as adaptive antenna arrays
and multi-user detection. Both wireless network architectures are transforming
from circuit-switched networks to packet-switched networks with implementation
of IP transport networks. The evolution path taken by service providers
will differ from case to case, and will be based on the second generation
wireless networks, existing customer base, availability of mobile devices
and applications, allocation of new spectrum, and global partnerships.
The
Implications of 3G CDMA for Wireless Data (4:00
- 4:30 pm)
Norman Toms (Sierra Wireless)
With the advent of 3G CDMA wireless
data, the task of equipment manufacturers such as Sierra Wireless becomes
both easier and more difficult. On one hand, 3G CDMA wireless data
standards are vastly more capable and efficient than previous offerings,
and therefore much more attractive to both customers and operators.
On the other, 3G CDMA is a family of standards, not a single specification.
Not only must designers meet demanding technical specifications, they must
assess the merits of alternative upgrade paths and, in some cases, support
multiple standards or options. In this presentation, the nature of
the market for 3G wireless data products will be reviewed, and manner in
which the Sierra Wireless product line has evolved in response to the 3G
challenge will be described. The steps being taken to ensure that
the needs and requirements of both customers and operators are met will
be discussed.
Panel Discussion/Q&A Session
(4:30
- 5:00 pm)
Moderator - James K. Cavers
(SFU)
During the Panel Discussion/Q&A
Session, the group will have an opportunity to discuss some of the issues
raised during the presentations.
