    China’s growth strategy as set out in the 11th 5-year plan in 2005 called for upgrading of product quality, the development of an innovation society, and reduced reliance on foreign intellectual property with high license fees. Consistent with this policy, China has been involved in recent years with the development of a Chinese standard in third generation (3G) mobile phone technology, both in negotiating the standard and seeing it through to commercialization. This is the first case of a developing country both originating and successfully negotiating a telecommunications standard and this experience raises issues for China’s future development strategy based on product and process upgrading in manufacturing. We argue that while precedent setting from an international negotiating point of view, the experience has thus far is unproven commercially. But the lessons learned will benefit future related efforts in follow-on technologies if similar Chinese efforts are made.This paper documents Chinese standard-setting efforts from proposal submission to ITU to the current large-scale trial network deployment in China and overseas trial networks deployment. We discuss the underlying objectives for this initiative, evaluate its effectiveness, and assess its broader implications for Chinese development policy.

    PhDWhen this research was started, TD-SCDMA (Time Division Synchronous Code Division Multiple Access) was still in the research/ development phase, but now, at the time of writing this thesis, it is in commercial use in 10 large cities in China including Beijing and Shang Hai. In all of these cities HSDPA is enabled. The roll-out of the commercial deployment is progressing fast with installations in another 28 cities being underway now. However, during the pre-commercial TD-SCDM trail in China, which started from year 2006, some interference problems have been noticed especially in the network planning and initialization phases. Interference is always an issue in any network and the goal of the work reported in this thesis is to improve network coverage and capacity in the presence of interference. Based on an analysis of TD-SCDMA issues and how network interference arises, this thesis proposes two enhancements to the network in addition to the standard N-frequency technique. These are (i) the introduction of the concentric circle cell concept and (ii) the addition of a relay network that makes use of other users at the cell boundary. This overall approach not only optimizes the resilience to interference but increases the network coverage without adding more Node Bs. Based on the cell planning parameters from the research, TD-SCDMA HSDPA services in dense urban area and non-HSDPA services in rural areas were simulated to investigate the network performance impact after introducing the relay network into a TD-SCDMA network. The results for HSDPA applications show significant improvement in the TDSCDMA relay network both for network capacity and network interference aspects compared to standard TD-SCDMA networks. The results for non- HSDPA service show that although the network capacity has not changed after adding in the relay network (due to the code limitation in TD-SCDMA), the TD-SCDMA relay network has better interference performance and greater coverage

    Balancing Between ‘De Facto’ and ‘De Jure’ in Standard-setting Strategy by a Latecomer Country: The Case of ICT Industry in China

    The main objective of this study is to gain insights into the complexities of the standard-setting process involving a latecomer country. Standards are identified into two categories: market (de facto) standards arising from market interactions and formal standards (de jure) arising from mandatory specifications by public authorities. The study focused on two research questions: (i) What are the different factors that influence the outcome (success or failure) of a proposed standard by a latecomer country? (ii) How does a latecomer country navigate between de facto standard and de jure standard? It analysed two cases (WAPI - a failure and TD-SCDMA - a success) to examine the extent of government support for a standard setting that needs to balance between the de facto standard and de jure standard. The study found that standard competition is a complicated interplay between technology, markets, politics and institutions. The experience of two cases suggest that a proposed standard should judiciously combine partly a ‘de jure standard’ which aims to protect national interests and achieve a national goal, and partly the ‘de facto standard’ to meet the technology trend, market demand, as well as the end users’ welfare.

    Chinese institutions and standardization: The case of government support to domestic third generation cellular standard

    Get PDF
    There are unique and distinct institutional processes associated with the Chinese government's support of the domestically developed third generation (3G) cellular standard, TD-SCDMA. After postponing several times, China awarded three third generation cellular licenses in January 2009: a TD-SCDMA license to China Mobile, a CDMA 2000 license to China Telecom and a WCDMA license to China Unicom. The Chinese government has demonstrated a clear bias in favor of TD-SCDMA. This article examines the role of formal and informal institutions in shaping the Chinese 3G landscape. This paper makes two contributions to the literature. First, this work extends studies on institutional theory focusing on standardization to the context of China. Second, unlike most ICT research which deals with standards originated in the West, this paper's focus on developing country-originated standard provides novel and unique insights related to institutional processes

    INNOVATIVE CITY IN WEST CHINA CHONGQING

    Get PDF
    This working paper offers insights on science and technology in China with supporting official and interview data. The paper, as evidenced from the title, is indicating the future role of Chongqing and its evolution primarily focusing on the period of rapid development of the Municipality after Chongqing became a political entity on the same level as provinces of China. This has coincided with the planning, construction and completion of the Three Gorges Dam Project involving the resettlement of 1,000,000 people – most them coming to the rural areas Chongqing Municipality. Three major sub-themes are highlighted. First, the city played important role during more than 2000 years of its history (in 1981, for example it became first inland port in China open for foreign commerce). In the XX century Chongqing was national capital during the Second World War and the Japanese invasion (Nationalists government). Since then it enjoyed higher political status and economic independence than any other city of the same size in whole western China. Second, the municipality’s geographical position and demographic condition makes it quite unique in West China. It has a population of 31 million, an area of 82 square km, a population density of 379 persons per km2 and a location at the upper reaches of Chang (Yangtze) River. This makes it the gate of Southwest China. Third, Chongqing has a strong basic multi-faced economy in the region. Central investment since the 1950s has assisted the development of a relatively strong modern industrial base in the city. Despite the post-Mao reform era’s impact on social and economic disparities as between the coastal areas and the west, Chongqing remains one of the China’s strongest city economies. Its industrial output value ranked 11th among the 35 biggest city economies in China in 2000, though it ranked behind the top ten most industrialized coastal cities, all of which had attracted much greater foreign investment during the reform era. The campaign to Open up the West provides Chongqing with the opportunity to act as the growth pole for a number of less industrialized provincial-level units in north-west and south-west China. Fourth, the initiatives by central authorities and the extraordinary task of Three Gorges Dam project required among other great tasks also relocation of over 1,2 million people, the rebuilding of two cities, eleven county towns and one hundred sixteen townships from the site of Three Gorges Dam water reservoir. Until 2005 there were already almost one million residents resettled. Less than 20 per cent moved outside Chongqing municipality and the majority was to be accommodated within the region of Chongqing Municipality.Regional development; clusters; Regional innovation System (RIS); Development block; competence block; technology system; High Technology Parks; Overview of Science and Technology; FDI

La transmission de la voix et des donnĂ©es Ă  travers les rĂ©seaux de tĂ©lĂ©communication mobile permet d'envoyer des informations et de diriger des transactions d'une maniĂšre nouvelle. Cela crĂ©e un nouveau domaine d'affaires qui s'appelle du commerce mobile, une affaire Ă©tendue basĂ©e sur l'Internet avec de nombreux des caractĂ©ristiques uniques ajoutĂ©s. Comme un soutien fondamental du plate-forme, les rĂ©seaux de la tĂ©lĂ©communication mobile joue un rĂŽle essentiel dans le commerce mobile. Leurs caractĂ©ristiques techniques et le dĂ©ploiement dĂ©terminent l'essence pour le commerce mobile. Dans cette mĂ©moire, nous Ă©tudions et prĂ©sentons les caractĂ©ristiques techniques des technologies communications mobiles du rĂ©seau 1G Ă  3G et au-delĂ . Nous Ă©tudions Ă©galement les technologies WLAN et WAP qui sont courantes dans le commerce mobile en Chine et dans le monde. Le commerce mobile est en train de se dĂ©velopper, le nombre d'utilisateurs de tĂ©lĂ©phones mobiles sont de plus en plus en Chine et dans ce monde. Les utilisateurs mobiles Ă©normes en Chine ainsi que la maturitĂ© des technologies 3G affichent un fort potentiel pour offrir et d'adopter plus les nouveaux services mobiles. AprĂšs rĂ©viser l'Ă©volution du commerce mobile et l'histoire du succĂšs i-mode au Japon, nous nous concentrons sur le mobile du marchĂ© chinois de maniĂšre Ă  dĂ©couvrir son marchĂ©, l'infrastructure du rĂ©seau mobile, et le modĂšle d'affaires. FondĂ© sur la base de notre enquĂȘte sur le commerce mobile chinois, nous prĂ©sentons, selon notre jugement, les services mobiles et des applications que sont convenables pour la Chine. Parmi eux, nous pensons qu'il y a la tendance sur les services basĂ©s sur la localisation et services orientĂ©es de l'architectures. Cette tendance peut attirer plus d'attention Ă  offrir de nouveaux services. En plus, elle peut offrir des services d'intĂ©gration et de personnalisation qui viennent de fournisseurs de services mobiles et des utilisateurs finaux. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Gestion intĂ©grĂ©e et Ă©cosystĂ©mique, Principe de prĂ©caution, Communication entre acteurs, Risques sur l'environnement et la santĂ©

    The Challenges of Technology and Economic Catch-up in Emerging Economies

    Get PDF
    This book synthesizes and interprets existing knowledge on technology upgrading failures as well as lessons from successes and failures in order to better understand the challenges of technology upgrading in emerging economies. The objective is to bring together in one volume diverse evidence regarding three major dimensions of technology upgrading: paths of technology upgrading, structural changes in the nature of technology upgrading, and the issues of technology transfer and technology upgrading. The knowledge of these three dimensions is being synthesized at the firm, sector, and macro levels across different countries and world macro-regions. Compared to the old and new challenges and uncertainties facing emerging economies, our understanding of the technology upgrading is sparse, unsystematic, and scattered. While our understanding of these issues from the 1980s and 1990s is relatively more systematized, the changes that took place during the globalization and proliferation of GVCs, the effects of the post-2008 events, and the effects of the current COVID-19 and geopolitical struggles on technology upgrading have not been explored and compared synthetically. Moreover, the recent growth slowdown in many emerging economies, often known as a middle-income trap, has reinforced the importance of understanding the technology upgrading challenges of catching-up economies. We believe that the time is ripe for “taking stock of the area” in order to systematize and evaluate the existing knowledge on processes of technology upgrading of emerging economies at the firm, sector, and international levels and to make further inroads in research on this issue. This volume aims to significantly contribute towards this end

    Cloud RAN for Mobile Networks - a Technology Overview

    Get PDF
    Cloud Radio Access Network (C-RAN) is a novel mobile network architecture which can address a number of challenges the operators face while trying to support growing end-user’s needs. The main idea behind C-RAN is to pool the Baseband Units (BBUs) from multiple base stations into centralized BBU Pool for statistical multiplexing gain, while shifting the burden to the high-speed wireline transmission of In-phase and Quadrature (IQ) data. C-RAN enables energy efficient network operation and possible cost savings on base- band resources. Furthermore, it improves network capacity by performing load balancing and cooperative processing of signals originating from several base stations. This article surveys the state-of-the-art literature on C-RAN. It can serve as a starting point for anyone willing to understand C-RAN architecture and advance the research on C-RA
