Forecasting demand for low earth orbit mobile satellite service in Korea

Forecasting a new service diffusion process is critical in designing marketing strategies and analyzing the costs and benefits for service providers. It is very difficult, however, in cases that data are not available. We suggest the combination of analogy and survey to forecast the demand for Low Earth Orbit (LEO) mobile satellite service in Korea. First, we analyze the diffusion of existing mobile phone service, which is similar to LEO service. The diffusion parameters for mobile phone service are then used in a model for LEO service. A survey was made on two hundred fifty‐five subscribers of existing mobile phone service in Korea. We estimate the potential market size of LEO service by applying the logit model to the survey data. Then, we forecast the annual demand for LEO service in Korea from 1998 to 2005. We also derive the price elasticity of market potential of LEO service. This revised version was published online in August 2006 with corrections to the Cover Date.     

The Digital Age of Mobile Cellular Network in Germany and China ：Policies,Technologies and Markets （Part Ⅰ）

The German Postal Reform I in 1989 introduced competition in the mobile cellular market. German cellular operators, DeTeMobil, Mannesmann, E-Plus and VIAG Interkom, built D1-, D2-, E1-and E2-Netze based on GSM standards made in Europe. China Unicom was created in 1994 and China Telecom was separated from MPT in 1995. China Telecom and China Unicom competed in a duopoly from the mid-1990s onwards and the cellular services provided by them also rely on GSM standards. China Telecom additionally deployed XLT technology (PHS) from the late 1990s onwards. While DeTeMobil and Mannesmann conquered approximately 80%-90% of the market throughout the 1990s and were the two dominant market players in Germany, China’s cellular market was mainly controlled by China Mobile. In Germany, prices related to cellular technology continued the downwards trend as a major result of the process of deregulation, liberalisation and competition. In China, price wars had led to significant price reductions in the cellular market. Although network operators in both countries strived to deliver differentiated cellular services, the two national markets in the 1990s were visibly shaped by product homogeneity.

Analyzing competitive and collaborative differences among mobile ecosystems using abstracted strategy networks

During the last 5 years, we have witnessed extraordinary development in the mobile market. Apple’s launch of the iOS platform and associated App Store marketplace turned the market around, and Apple became the leading company in the business. This development caused existing players, such as Nokia, to renew their business and attracted new players, such as Google and Microsoft, to enter the market and introduce their own mobile platforms. To understand this development, we suggest that a generic abstracted model of the ecosystem around mobile platforms should be developed describing how the actors, including users, individual app developers, companies, and digital services, are connected and interact. In this work, we propose that competition and collaboration in this kind of abstracted ecosystem can be modeled and analyzed using network analysis. In our research, we derived weighted competition and collaboration networks for each mobile platform from an expert survey, and by calculating companies’ degree centrality in their networks at different times we were able to illustrate how companies’ strategies to build and maintain an ecosystem differ and develop over time. We believe that this kind of analysis is useful both for companies that build ecosystems and also for companies that plan to do business in them. The former can use it to compare their strategy with existing competitors and also evaluate emerging new ecosystems and the latter to compare and choose between possible ecosystems with which to do business.

Trunked private mobile radio-a lead from the electricity industry

The author briefly reviews the development of private mobile radio and the problems it is now encountering due to limited frequency spectrum. To get the maximum use from a limited frequency spectrum, trunking has been adopted. Trunking increases the number of channels potentially available to a user, allowing a better trade-off between load and grade of service. The Joint Radio Committee is proposing the use of trunked PMR schemes for the electricity supply industry in England, Wales and possibly Scotland, and the gas industry for England, Wales and Scotland. Each industry will be allocated 36 channels. The plan for the electricity supply industry is described and the architecture of the system is briefly mentioned. The signalling protocol MPT 1327 will be used. The management of channel contention is also discussed     

Financial implications of rate plan optimization in the post-paid mobile market

In the competitive mobile telecommunications market, rate plans with new pricing structure are introduced regularly. Prior literature reveals that subscribers often overpay for their service because of inappropriate rate plan selection. Having subscribers on financially-optimal rate plans is found to be beneficial from both churn reduction and tenure maximization perspectives. However, the revenue implications of deploying such a customer relationship management strategy have not been thoroughly researched. This paper examines the revenue implications by analysing 1249 post-paid mobile subscribers in Canada over a 44-month period. This research also provides insights into some potential moderators that may influence the strengths of the linkage between rate plan suitability and revenue contribution.     

一种新颖的5.8GHz圆极化接收整流天线

提出了一种新颖的用于微波能量传输的圆极化接收整流天线。截角矩形微带天线作为接收天线,在工作频率为5.8GHz时得到的轴比为1.2dB,使用肖特基势垒二极管作为整流部分。通过测量接收整流天线的能量转换效率,证明发射天线和接收整流天线之间的极化未对准对于输出功率和能量转换效率的影响都很小,所以这种接收整流天线非常适用于移动物体间的微波能量传输。
