Broadband·Convergence·Green New TD Tech: quot;New Heightquot; of the TD Industry
New TD Tech, New Network,

optimization experience, and end-to-end fast service capability, plays a decisive role in deployment and O&M
of the network.
Through years of painstaking work, the two parent companies have accumulated the best experience in the
industry. In terms of the market share, Huawei and Nokia Siemens Networks cover almost half of the GSM
and CDMA markets. In 2007, on the world's WCDMA market, the two companies won more than 50% of new
market in all. The customers include the world's top operators such as Vodafone, France Telecom–Orange,
Deutsche Telekom, Telecom Italia, AT&T, and America Movil. As for the GSM network of China Mobile, the
two parent companies of TD Tech have a total market share of nearly 40%. The richest experience in
constructing large mobile networks and the best marketing and service networks constitute the two
companies' powerful service capabilities. In China, the service network has extended to the county-level
towns, with more than 3,000 wireless engineers offering the first-class services to the customers.
New Network: Driving Force for the Best User Experience
After more than ten years' rapid development, China Mobile, by virtue of the state-of-the-art technologies,
has built its GSM network into a super network with a wide coverage, providing excellent mobile
communications services for 430 million GSM users. With the mobile users growing constantly and rapidly,
the GSM network and TD network will co-exist in a long time thanks to their respective advantages, the
former providing perfect low-cost voice solutions and the latter focusing on meeting the ever increasing data
service demands of high-end users. End users can implement seamless switchover between the two
networks as required based on the specific policies such as the service-based switchover and network load-
based switchover. Whether the switchover between the GSM network and the TD network can be realized
smoothly decides the continuity of services and exerts a direct influence upon the user experience.
As the two parent companies of TD Tech, Nokia Siemens Networks and Huawei have in-depth
understanding on the uniform network planning, service
planning, deployment, and operations of the 2G and 3G networks and have accumulated a huge amount of
key technologies such as 2G/3G interoperability, high-speed switchover, and uniform wireless resource
management. The new solutions of TD Tech inherit the mature experience and core algorithms of the parent
companies, enhancing the network quality and user experience and helping the operators heighten the user
loyalty.
New Platform: Core DNA of the Super Mobile Network
Without the reliability of the NE equipment, the network cannot be reliable. To meet the operators'
requirements for the high reliability and maturity of the products and solutions, TD Tech imported core
technologies and leading platforms that have stood the test of large-scale commercial use from the parent
companies, for example, the new BTS platform with more than 1 million carriers' shipment, thus achieving a
satisfactory effect.
Uniform BTS platforms and base station controllers are the foundation for the TD network's smooth evolution
into the future. The new platforms provided by TD Tech not only ensure the high reliability and stability of
networks through the mature QoS mechanism but also have the capability to support the mobile broadband

network. Enabling the network to evolve into the future model, the platforms protect the operators' long-term
investment.
In response to the operators' urgent need for a quot;green and convergedquot; mobile broadband network that can
evolve into the future model, TD Tech developed the new-generation green BTSs. Based on the fourth-
generation BTS platform of Huawei that leads in the industry, TD Tech introduced the mobile broadband
technology into the TD field. Firstly, the broadband RF technology, such as multi-carrier transceivers and
broadband power amplifiers, is adopted, thus realizing the highest integration of the platform in the industry.
Compared with similar products in the same filed, the capacity of the RRU is greatly enhanced, with the
weight and volume decreasing by more than 30%. Secondly, the SDR multi-system convergence platform
based on LTE-Ready enables TD-SCDMA and TDD LTE to share the uniform platform in the new-generation
green BTS. The advanced broadband RF technology makes possible the seamless convergence between
the two systems. When the software is updated, the system switchover can be realized. Thus, the smooth
evolution can be fully ensured. Thirdly, the all-IP architecture, core, interfaces, and service assurance
mechanism can not only cut down the transmission cost and enhance the QoS to a great extent but also
facilitate the fast introduction and deployment of the broadband services in addition to the smooth evolution
of the network. Finally, the end-to-end green measures, such as the multi-core cost-efficient power amplifying
technology and three-level power amplifier shutdown, improve the efficiency of the power amplifier to 28%.
The efficiency of the integrated equipment is 17.4%, far above than the average industrial level of 8%. For
different scenarios, different innovative BTS solutions were developed so that the total OpEx decreased by
30%. Thus, the targets for energy conservation and emission reduction, fast construction of network, and
reduction of TCO can be realized.
New TD Tech, new network, and new platform are the joint commitments made by Huawei, Nokia Siemens
Networks, and TD Tech. While the TD industry and China's 3G industry march towards the new age, such
commitments seem to be especially valuable.
