Recently TD-SCDMA standalone network solution has been an important focus for TD-SCDMA industry and the public. Both “Does the maturity of TD-SCDMA technology have the ability to set up a full 3G network independently?” and “Are the basic technical condition and marketing condition available for TD-SCDMA standalone network solution?” have been the key factors for TD-SCDMA commercialization and industry scale.

Aiming at above focuses, TD-SCDMA Forum held The standalone deployment of TD-SCDMA network seminar on 25th.Jan.2005 in Beijing Marco Polo Hotel. More than fifty delegates joined the seminar from twenties companies including Siemens/Huawei JV (TDTECH), Datang Mobile, Nortel Networks, ZTE, Putian Information Research Institute, Motorola, UTStarcom, Alcatel-bell, T3G, COMMIT, CIYT etc. This seminar was sponsored by Ms. Fujun, vice Secretary-general from TD-SCDMA Forum.

Nortel Networks, ZTE, Putian, Siemens/Huawei JV, Datang Mobile gave deep analysis on TD-SCDMA standalone network solution with following presentations: “Key factors for TD-SCDMA standalone network solution”, “Dedicated research on TD-SCDMA standalone network solution”, “The analysis of coverage modes in TD-SCDMA standalone network solution”, “Commercial solution for TD-SCDMA standalone network solution ”, “TD-SCDMA market development prospect” etc.

Delegates summarized the key factors for TD-SCDMA standalone network solution firstly: to realize seamless coverage; to meet the requirement of high capacity for more subscribers; to resolve the interference problem between two different systems; to realize smooth handover between different technologies; to support maximum data rate transmission etc. To promote TD-SCDMA comprehensive competitive power, delegates emphasized that following aspects should been strengthened: to promote TD-SCDMA specific applications; to reinforce the QoS of applications and services; to pay attention to the cost of TD-SCDMA buildup network; to enhance TD-SCDMA standard architecture and technology migration etc. At the same time, the capability of comprehensive O&M, interaction between network planning and network optimization tools should be enhanced to reduce the difference between simulation and real environment, between planning network and commercial network.

Since TD-SCDMA naissance, its existence and development have proved its inherent value to all over the world. So far, both theory and practical testing have proved that TD-SCDMA has the ability to build full 3G network independently. Compared with other two 3G standards, TD-SCDMA has higher spectrum efficiency. To support high traffic of data services, its advantages to deal with asymmetric services efficiently can’t be replaced by any FDD technologies. Currently TD-SCDMA capacity performance has bee accepted by the industry. It also has strong wide-coverage capability via its unique key technologies: smart antenna and uplink synchronization can effectively eliminate breath effect; joint detection can reduce the Multiple Address Interference (MAI) furthest regardless it is from intra-cell or inter-cell. Now this technology is mature for both commercial terminal and NodeB. The number of new subscribers will not affect the total interference level so sharply. TD-SCDMA technical advantages bring its specific operational advantages. It can set up the network in different phases according to the traffic requirement which can effectively avoid the huge investment in the initial phase of 3G network installation. Additionally TD-SCDMA has distinct advantages just because it started late. It has more space for innovation than the other two 3G standards which can benefit technology migration and convergence.

During the seminar, Putian introduced the different technologies used when TD-SCDMA covers urban, rural and specific areas. Siemens/Huawei JV introduced the solution of “To use distributed system to cover rural areas, highway, mountainous areas etc”. With detailed instance, the reliability and maturity of TD-SCDMA technology are showed clearly to the audiences. All the delegates agreed that through current technology realization, TD-SCDMA can support all 3GPP accordant services and provide operators flexible, seamless, hierarchical solution, even to the areas that have stricter requirement for data service. Delegates also believe that excellent TD-SCDMA standalone network will surely be realized with good product design, fine implementation and professional network optimization procedures verified by real networks.

Vice-president of Datang Mobile Mr. Xie Yongbin added that the capability to setup a TD-SCDMA standalone network solution has been perfected since mature industry chain and multi-vendor environment were formed in last year. The marketing advantage is emerging day by day. TD-SCDMA standalone network solution can support all the 3G services. While FDD needs TDD as supplementary implies that FDD has some deficiencies to some extent. Main R&D suppliers such as Siemens/Huawei JV expressed that dedicated researches about TD-SCDMA standalone network solution have been carried out from technical aspect.

After this seminar of “The advantages of TD-SCDMA standalone network solution”, delegates came to an agreement that from technical aspect TD-SCDMA has the capability to realize full 3G network. How to implement this depends on 3G license release and service requirements. Currently government and operators steer this console mainly. Ms.Fu Jun, Vice Secretary-general of TD-SCDMA Forum expressed Forum will organize more activities or meeting focusing on this issue recently. At the same time, in the 26th ~27th April’s “2005 TD-SCDMA Summit” this issue has been listed as important topic.
