Nortel Networks showcased its innovations across all wireless access
technologies and some of its recent contract wins throughout Asia. Nortel's
delegation to this event was led by Richard Lowe, president, mobility and
converged core networks. "3G is finally here and we believe the success of
3G and beyond will depend on providing full broadband mobility, true multimedia
experience, and layered security. And Nortel will lead the industry beyond
3G," commented Lowe.

Nortel is one of the few players which has focused on
solutions to address various technologies, be it for the CDMA world, or the GSM/UMTS
realm or WLAN. It is also addressing the challenges associated with achieving
the next set of gains in capacity, coverage, and spectral and power
efficiencies.

"In the CDMA world, we have already supplied CDMA
1xEV-DO solutions to 12 out of the 21 operators as of July 2005. Further, the
market trials for CDMA 1xEV-DO Revision A solution, which will significantly
increase data rates, will begin in 2006," added Lowe. It has also made
significant inroads in the GSM/UMTS space with its High Speed Downlink Packet
Access (HSDPA) technology. It is believed to be the first to have completed an
end-to-end call using its HSDPA technology on a commercial network.

In the wireless LAN space, Nortel has made good progress with
its decentralized network architecture for wider community coverage (Wireless
Mesh Network). It is also working on enabling internetworking between wide-area
cellular networks and WLANs. It completed the seamless handoffs of voice and
data services between a 3G UMTS cellular network and a WLAN with BB Mobile,
Japan. "The future ahead is multiple-input multiple-output (MIMO) with a
modulation scheme called Orthogonal Frequency Division Multiplexing (OFDM). This
is a new air interface technology that combines the MIMO, an antenna processing
technique, with OFDM.

This technology has shown that data transmission speeds
increase by 25 times as compared to today's commercially deployed UMTS
networks and five times faster than HSDPA. Our first application of OFDM-MIMO is
in our WiMax solution and this technology is being considered as an access
technology for the evolution of both CDMA and UMTS networks. The 3GPP2 standards
bodies are discussing the incorporation of OFDM-MIMO in the evolution of 1xEV-DO
and 1xEV-DO Revision A networks," informed Lowe. Nortel with its JV partner
LG is also actively involved in rolling out WiMAX service in Korea and in
numerous trials worldwide.

    DVD-quality streaming video, fast downloads of very large files
    including music, as well as Virtual Private Network (VPN) access to
    corporate networks. Nortel and Lucent have deployed commercial HSDPA
    networks.

It was not only Nortel that showcased its CDMA 1xEV-DO
Revision A technology. Motorola and Lucent were some of the others to showcase
this technology. Motorola unveiled its prototype CDMA 1xEV-DO Revision A
solution at 3G World Congress and Exhibition 2005. "Motorola's all-IP
CDMA architecture is ready to support Revision A, and our integrated radio
access network solution lets operators leverage their existing investment as
they make the migration to this new technology," said Bruce Stone, senior
vice president, Cellular Networks, Motorola. Its CDMA 1xEV-DO Revision A
solution is planned for commercial availability in 2006.

Lucent Technologies' showcased how to deliver Value over IP
through its broad portfolio of end-to-end solutions and applications through its
over-the-air CDMA20001xEV-DO Revision A and HSDPA technologies. It also
showcased its Bell Labs-developed IMS applications such as Active Phone Book, an
advanced personal directory service that goes beyond the standard "buddy
list" by providing a common, unified phonebook supporting an array of
applications and devices that tracks and centralizes contact data including
phone numbers and e-mail addresses and incorporates presence and location data
for subscribers' buddies.

Interestingly, a lot of companies, Indian as well as global,
have either been doing cutting edge technology development in the 3G space in
India or plan to set shop in India. For example Infinion Technologies is doing a
significant portion of its software development for ultra low cost phones from
Bangalore in India. Clemens Jargon, vice president & general manager, BU
Feature Phone, Infineon Technologies AG, informed, "We have announced the
availability of our latest multimedia mobile phone (MP-EU) reference design
platform here. The MP-EU platform is the industry's most integrated platform
supporting UMTS, EDGE and GSM/GPRS standards. This platform enables the mobile
phone manufacturers to smoothly evolve from 2.5 G to 3G. Current UMTS phones
need around 300-450 components and with Infineon platform, the number is reduced
to below 200. It also enables the manufacturers to speed up introduction of the
next generation phones by up to 30 % from today's 14 months on an
average."

While the baseband processor and protocols come from Infineon
global, the software comes from India. India's Jataayu Software, a leading
mobile infrastructure software vendor, was demonstrating it multimedia messaging
services capabilities. "Jataayu's focus has been on the handsets space.
We provide browsers, MMS, instant messaging, SyncML data synchronization, WAP
gateways etc. Today there are over 25 mn handsets using Jataayu products and
this number is expected to triple in the next 12-18 months. We believe HTML
browser technology will become important and our browser will be launched in
March-April 2006," said Raj Kesarimall, director, Jataayu Software.

TensorComm was another company, which was demonstrating its
pioneering technology. TensorComm announced the availability of the next
generation of its interference cancellation technology that will apply to
CDMA2000 (1X and 1xEV-DO) and WCDMA (including HSDPA) networks. The enhancement
is specifically optimized to address a fully loaded code space, a condition
often seen in EV-DO systems and at base stations on 2.5G and 3G networks.
Further, it is also completely compatible with 1X, WCDMA and HSDPA networks,
where the code space is not always fully utilized.

According to John Thomas, CEO and founder, TensorComm,
"Our patented Interference Cancellation Technology (ICTâ„¢) delivers a
cost-effective, easily deployable CDMA and WCDMA component that fits in a mobile
device without requiring form factor changes or radio frequency (RF) redesign.
The previous version of ICT successfully completed operator commercial network
field trials and yielded an average gain of 1.97 dB. It is well recognized that
a 1.25 dB gain will provide an operator with a 40 % increase in capacity,
coverage and data throughput. With these latest improvements, average gains are
now expected in the 2.5-4.0dB range. Field evaluations on both EV-DO and HSDPA
networks will be conducted in the first quarter of 2006."

Starent Networks, a leader in next-generation mobile
infrastructure solutions, was demonstrating it Intelligent Mobile Gateway in

"3G
is fundamentally a different technology. Nortel has a big
opportunity."


Malur Narayan,

director,
Wireless Solutions, Nortel Networks

Nortel is
into all the 3G technologies. Which of those do you focus more on?



Nortel has always been neutral from the technology perspective. We have
been supporting both CDMA and GSM since the early 90s. Going forward we
will be present in all the 3G technologies.

You have a
JV with LG. What would it achieve?


LG Electronics and Nortel formed a joint venture (LG-Nortel Co. Ltd) to
offer leading-edge communications and networking solutions in the wireline,
optical, wireless and enterprise markets in South Korea and the rest of
the world. LG and Nortel have been selected to deploy HSDPA/WCDMA networks
for KTF and SKT. The JV is strategic for us because Korea is a very
advanced market in terms of technology adoption. It gives us not only the
access to the Korean market, but also allows us to understand the consumer
behavior and applications.

Nortel has
won fewer deals compared to others in the wireless markets in India. Will
it mean limited opportunity for Nortel?

The cellular market in India has
been in existence for almost nine years. Yet, the mobile penetration is
around 6% and the market is quite open. It is still a long way to go
compared to China. So the winners are not yet decided. In the early days,
Nortel did not have a significant presence in GSM and that probably hurt
us initially. But we have won some contracts now and are working on a few
more. There is still a lot of potential in India.

Will the
operators migrate to 3G service provision with their existing vendors?

3G is fundamentally a different
technology. So the markets are wide open. In Europe, we were not with many
operators of GSM. But a lot of them when they started 3G services bought
Nortel solutions. The reason, one is going from GSM, fundamentally a TDM
technology to WCDMA, which is a CDMA-based. The transition is not easy to
make. It is a fairly big upgrade exercise unless one bought dual mode base
stations. Majority of the sites installed in India are not dual mode and
they will have to upgrade their sites one by one. It is as good as signing
a new vendor. We use this technology discontinuity to position ourselves
in 3G.

What is the
edge that you have in 3G?

3G and 4G technologies are more
about data. Compared to the traditional cellular vendors, Nortel is one of
the strongest players from the data perspective. We have a strong IP core,
data technologies, and years of experience on the access/RF side.
Together, it gives us a unique combination to offer advance features to
the operators in the 3G to enable them to be more efficient and offer
better value added services.

Which 3G
technology will prevail in India?

There is still a strong place for
CDMA and that is not going to go away. And many of the operators are
looking at EVDO etc. to provide broadband through CDMA. WCDMA, obviously,
is also going to have a spot as many of the GSM operators are looking at
migrating to this. The roll out for that will little bit slower than 3G
CDMA roll out.
