P1.1: Dreaming of radio so
perfect that no business plan will need to be good
Operator’s perspective on the enabling and disruptive powers brought in
by advances in the radio technology. What are the major hopes, fears,
and strategies of the mobile industry? How to position evolving RAN
concepts in the regulatory and spectrum access framework?
About the speaker
In charge of Eurotel’s new product development Eduard has been the
project manager responsible for structuring and deployment of CDMA
service in the Czech Republic. The landmark projects ultimately become
the first CDMA2000 1xEV-DO network in Europe. His main interests in the
capacity of Technical Strategy Manager at TO2CR are issues of
standardization, convergence, technological sustainability and spectral
as well as competitive policy analysis.
Eduard holds a Master degree in the Theory of Control from the Faculty
of Electrical Engineering of the Czech Technical University in Prague
and MBA from Katz Graduate School of Business University of Pittsburgh.
He is on the Board of Directors of the IA450.
The presentation gives a brief corporate profile of Huawei Technologies
Inc. -- a leader in providing next generation telecommunication
solutions -- and addresses future wireless network development trends
from the equipment manufacturer perspective.
Ten years ago, the major telecommunications standards organizations in
the world were developing technologies and making proposals to the ITU
for IMT-2000. In May 2000, the ITU issued recommendation M.1457
defining a family of five radio interfaces (CDMA-DS, CDMA-MC, CDMA-TDD,
TDMA-SC, and FDMA/TDMA). The most important of these radio
interfaces have been CDMA-DS (direct spread), commonly called WCDMA
(UMTS or UTRA) developed by 3GPP and CDMA-MC (multi-carrier), commonly
called cdma2000, developed by 3GPP2. The WCDMA and cdma2000 radio
interfaces have been continuously evolving so that the performance of
their latest releases far exceeds that developed in the late
1990s. The first major step was the development of 1xEV-DO by
3GPP2 which used short transmissions, fast feedback, hybrid ARQ, and
higher order modulation on the downlink. Both 3GPP and 3GPP2
incorporated modified versions of these techniques in HSDPA (3GPP
Release 5) and cdma2000 Revision C (1xEV-DV). The next step was
using short transmissions, fast feedback, hybrid ARQ, and 8PSK to
enhance the uplink in cdma2000 Revision D and 1xEV-DO Revision A with
similar mechanisms then being incorporated into HSUPA (3GPP Release
6). 3GPP2 added OFDM for MBMS and, in 1xEV-DO Revision B,
multi-carrier and 64-QAM. 3GPP Release 7, called HSPA+, added
MIMO, better MBMS, and 64-QAM on the downlink. 3GPP is likely to
include multi-carrier (dual-cell HSPA) among other Release 8
enhancements. 3GPP2 has recently embarked upon projects called
1x-Advanced and DO-Advanced to enhance cdma2000 and EV-DO. In
additional to the continual enhancements of the CDMA-based radio
interfaces, 3GPP and 3GPP2 have developed the OFDMA-based LTE and UMB
radio interfaces, which have now been included in the IMT-2000
recommendation, M-1457. This keynote looks back upon the progress
that has been made in standardization, performance, development, and
deployment of the two main 3G systems over the past ten years.
The presentation will conclude by projecting potential future
enhancements.

CDMA system, also called cdmaOne™. He led QUALCOMM’s and much of
the industry’s efforts in the design and development of the
third-generation cdma2000® system. Recently he has been focusing
on the evolution of 3G systems and the convergence of multiple
technologies. He is particularly interested in the implications
of these changes for the wireless industry. Dr. Tiedemann chairs
Working Group 3 of 3GPP2 TSG-C, which is responsible for the cdma2000®
(1x, 1xEV-DO and UMB) physical layers. Dr. Tiedemann has been
particularly interested in the technical issues related to handoff,
power and rate control, scheduling, control of random access channels,
advanced antennas techniques, and the tracking and paging of mobile
users. Dr. Tiedemann holds over 100 US patents and has
participated in over 40 papers, conference lectures, and industry
panels.
Prior to becoming involved with terrestrial wireless communications,
Dr. Tiedemann was involved with numerous commercial and military
satellite programs. From 1977 to 1988, Dr. Tiedemann was at MIT
Lincoln Laboratory.

P2.1: Bringing the Successful Internet Paradigm to the Mobile Domain
In addition to web browsing the online commerce, the Internet has
brought about a range of pioneering services and applications, such as
social networking, online dating and gaming, peer-to-peer applications,
etc. These innovations have generated billions of dollars in revenue in
recent years. An important question is whether mobile operators
can successfully bring the Internet paradigm to the mobile domain, and
whether they can offer their customers such a range of novel services
and applications tailored to the mobility context.
The era of the "killer application" has already passed, and the era of
the "long tail" in successful applications has begun. There will be no
new "killer applications" for mobile operators; instead, it is expected
that there will be a large number of smaller-scale services and
applications, which together will continue the blossoming of revenues
for operators and service providers. Furthermore, more and more future
content to be created and provided by mobile users themselves, and this
will accelerate the realisation of new streams of revenue. Given such
observations, future services will generate a huge amount of traffic
over mobile networks.
In view of the above, this talk will address some related issues and
questions. These include: What will be the nature of future
applications for mobile operators and service providers, and will the
success of current wired Internet services and applications translate
to the mobile domain? How can mobile operators deal with the huge
increase in traffic on their networks and the same time increase their
revenues proportionally? How can they offer these services
efficiently and cost effectively to their customers? What are the
optimal business models?
