The Research of Third Generation Mobile System Market Strategies

Tseng, Shun-Cheng 22 July 2002 (has links)
Abstract With the tremendous growing of mobile communication and internet market in the 90s decade, electronic commence (EC) and broadband multimedia also begin to demonstrate their market potential in next few years. We can almost be sure that a combination of these markets equals success. The 3G system, created to meet the requirements mentioned above, undoubtedly to be the star of future. Basically, the 3G system is an extension of the 2G system. There is no question that, to date, Japan has been the mobile Internet success story with its legendary i-mode service. But in much of the world, mobile internet market has generally not materialized quite as quick as anticipated, due to a number of factors. Mobile EC and multimedia markets are facing the same situation. It reveals that 3G market, unlike the explosively growing 2G market, will be full of uncertainty. This thesis focuses on the uncertain 3G market. Base on the theory of ¡§Strategy under Uncertainty¡¨ , we will provide some competition strategies for telecom operators. We also provide a risk¡Vanalysis model, with the theory of ¡¨ Discovery Driver Planning¡¨, for the operator to evaluate the high risk in such an uncertain market.

A Study of the Strategies of Third Generation Mobile Communication Service

Lin, Su-hui 14 June 2006 (has links)
The growth of the mobile communication subscription is the main driver of the operators¡¦ revenues, before the appearance of 3G mobile communication service. As the penetration rate of mobile phones jumped over 100% in Taiwan, it¡¦s obvious that the life cycle of the GSM system has shifted to the mature stage, which all of the operators are under the pressure of low growth rate of voice service and declining ARPU rate due to the fierce price war in the market, and started to introduce 3G service. The 3G mobile communication technology offers users higher speed data communication, mobile commerce solutions, and multimedia services on the current 2G mobile communication basis. This has brought hope to mobile communication industry. In order to enhance the value-added services, operators must evolve its current role, which simply provide equipment and infrastructure service, to become a total solution provider that can integrate the whole industry value chain vertically. Therefore, this study mainly focuses on the 3G industry value chain and the competitive strategies. Moreover, this study will discuss global mobile communication development circumstances and the operation strategies of the worldwide leading players, in order to come up with appropriate managing tactics. Hopefully, the successful experience from successful companies can help Taiwan operators to understand more about the trend of global communication market strategies

The Grandchildren of Immigrants : Employment, Earnings and Receipt of Social Assistance

Erik, Hedlin January 2009 (has links)
This paper studies the employment rates, earnings and social assistance of grandchildren to the immigrants that came to Sweden before 1960. The results indicate that there are differences regarding employment, earnings and social assistance between some of the third-generation immigrant groups and the third-generation native groups, especially when it comes to employment rates. No differences were however found for the grandchildren of immigrants from outside of Europe, but around 90 percent of them came from North America and many were return migrants. One conclusion from this paper is that differences in labor market outcomes between immigrant groups and natives may exist over several generations and that immigration policy may have very long lasting effects.

Toward the 3G telecommunication system-The Analysis of Business Strategies of Telecommunication Operators

Huang, Vincent 25 August 2003 (has links)
Abstract Mobile phone is one essential communication product to most Taiwanese nowadays. As the market approaching its full capacity, service providers are now facing more competitions than ever. Some much lower profit and decreasing number of users can also be expected. Hence all the telecommunication service providers are trying to increase their revenue through providing mobile digital services to compensate the decreasing revenue from voice sector. To be more precisely, telecommunication service providers are not solely telecomm operators after the integration with mobile data transfer. Mobile phone system is also changing from telecommunication system to a multifunctional mobile communication system. 3G (The 3rd Generation Mobile System) is the solution that meets new mobile communication requirements. The system is based in a new technology of wireless communication with a very high speed access to the Internet services. Mobility is the basic requirement of mobile networking service, the 3G system is enhancing the capability of mobile communication that allows us accessing the Internet, enjoying the multimedia entertainment, inquiring information, and doing mobile business anywhere. 3G is also giving the mobility to modern business activities. For instance, users can now accessing data, sharing interactive application software, and attending video conference through Internet and Intranet services. While users can now performing all these activities in anytime and place, the service boundaries between telecommunication, information, media, and entertainment will disappear. All these services will now be integrated, current fixed services will soon turn into mobile. We can watch video clips and receiving emails in the same time, also play on-line games with friends in any different corner around the world. From 9.6Kbps to 2Mbps, the data transmission speed of 3G system is 40 times faster than GSM system. It may now take 2 minutes to send a multimedia message with a photo and voice attachment, but in the future 3G system, it will be done within 5 minutes. Nonetheless, the 3G system is not only providing high speed data transfer services, but also the convenience of accessing data. The core technology of 3G is packed Internet Protocol which allows users to get wired anytime. Emails can easily be downloaded to the mobile phone handset too. Just press one button, employees can easily get connected with their company. Service providers will charge only when the users are retrieving data from the Internet, otherwise all services are free. The application of wireless services will be extended in the future. The needs of interaction between consumers and mobile equipment, also between one equipment and another will continue increasing. These interactions include system failure noticing, new order placing, or data transmitting. In addition to the telecommunication operators, businesses can also take good advantages of 3G to develop new applications. 3G will be a part of our life in the future. The licenses of 3G operators have already been issued in February 2002. How firms can develop one successful business model of mobile strategy has already become the critical issue for these operators. This research is focusing on the reactions of telecommunication market after the introduction of 3G services. The research topics include exploring the technical problems of 3G system, analyzing the impact of current GPRS, i-mode, MMS, WLAN, PHS to the 3G system, also examining the attitudes of different governments in launching the 3G system in the global market. A conclusion remark will be made with the analysis of current operations of services providers and the future trend of the market.

Přímá klasifikace metagenomických signálů ze sekvenace nanopórem / Direct Binning of Metagenomic Signals from Nanopore Sequencing

Lebó, Marko January 2019 (has links)
This diploma thesis deals with taxonomy independent methods for classification of metagenomic signals, aquired by a MinION sequencer. It describes the formation and character of metagenomic data and already existing methods of metagenomic data classification and their development. This thesis also evaluates an impact of the third generation sequencing techniques in the world of metagenomics and further specialises on the function of the Oxford Nanopore MinION sequencing device. Lastly, a custom method for metagenomic data classification, based on data obtained from a MinION sequencer, is proposed and compared with an already existing method of classification.
