Customer performance and non-financial organizational performance of the Nepalese cellular telecommunications industry

The study assessed a product or service by customers that met their needs and aspirations. It sought to examine the influence of non-financial customer performance (CP) measures on non-financial organizational performance (NFOP) in the Nepalese cellular telecommunications industry (NCTI). Using a structured questionnaire survey instrument, it employed a descriptive research approach. This study’s population included all the global system for mobile (GSM) customers of Nepal Telecom (NT) and Ncell. The sample comprised 385 customers delineated through non-probability sampling techniques. The study’s targeted respondents were postgraduate understudies, service holders, business people, and self-employed individuals. The survey instrument was composed of three sections comprising 28 data collection questions. A statistical package for the social sciences (SPSS) and analysis of moment structures (AMOS) programming were used to analyze the collected data. The study applied confirmatory factor analysis (CFA), path analysis (PA), and structural equation modeling (SEM) to evaluate the significance of the hypothesized paths. It was found that CP had a positive and significant relationship with NFOP in NCTI, with customer retention (CR) being a better predictor, followed by customer loyalty (CL), customer satisfaction (CS), and customer acquisition (CA). This was a cited representative study, not exhaustive, and would help to understand the key drivers of CP in the NCTI.

Feasibility Analysis of Indonesian Cellular Operator Consolidation Design

The high population and increasing growth in the penetration of the use of cellular telecommunications services in Indonesia have encouraged businesses to provide cellular telecommunications services in Indonesia. There are seven existing cellular operators who compete in attracting customers by providing services and prices that are considered to satisfy the customers. However, if seen from the operational performances and financial performances of cellular operators in Indonesia, there is an unbalanced and unfair competition between cellular operators. Consolidation between cellular operators is one of the solutions offered in overcoming the problems of Indonesia's cellular telecommunications industry. In this paper, the consolidation of the four largest cellular operators in Indonesia, namely Telkomsel, ISAT, XL and Three will be designed and analyzed by using the data of operational performance and financial performance of the cellular operators. The operational performance data used as parameters are the number of customers and Base Transceiver Station (BTS) of each cellular operator. While the financial performance data used are the data in the financial statements to calculate the financial ratios of cellular operators so that they can be used as parameters to measure the feasibility of a business company. This consolidated design scenario is designed by combining a maximum of two cellular operators. The results of the study indicate that consolidated design that illustrates the business feasibility and efficiency of the cellular telecommunications industry is consolidation between Telkomsel - Three and ISAT - XL. The feasibility analysis of the consolidation of cellular operators is expected to provide benefits and suggestion in balancing competition in the cellular industry and can improve the efficiency of the telecommunications industry.

835 MHz 및 1,800 MHz 대역에서 인체의 전기적 특성을 가지는 한국인 손 모양의 팬텀 제작

휴대전화의 이용이 증가하면서, 손에 미치는 전자파의 영향에 대한 관심이 증가하고 있다. IEC TC106에서도 휴대전화의 전자파 인체 노출량 평가 방법 표준에 손 영향을 반영하기 위하여 국제적인 교류 연구가 활발하게 진행되고 있다. 현재 상용화된 손 팬텀은 평균 서양인 손을 이용하고 있을 뿐만 아니라, 한 가지 형태의 파지(把持)만 가능하기 때문에, SAR 측정 결과에 대한 분석에 제한이 많은 실정이다. 손의 영향을 제대로 분석하기 위해서는 다양한 형태의 파지가 가능한 손 팬텀이 필요하다. 또한, 국내 환경에 맞는 손 팬텀의 개발이 필수적이다. 본 논문에서는 다양한 형태의 파지가 가능한 835 MHz 대역과 1,800 MHz 대역의 한국인의 젤리형 손 팬텀을 제작하였다. 제작된 손 팬텀의 전기적 특성은 비유전율과 도전율이 CTIA(미국이동통신산업협회) 권고 기준 값의 <TEX>${\pm}10%$</TEX>이내로서, CTIA에서 제시하는 오차 기준(<TEX>${\pm}20%$</TEX>)보다 더 우수한 특성을 나타냈다. 또한, 손 팬텀의 3D CAD(3차원 컴퓨터 이용 설계) 파일을 개발하여 손에 의한 SAR 영향 분석을 위한 시뮬레이션에서 활용할 수 있도록 하였다. 본 연구를 통해 제작된 젤리형 손 팬텀과 3D 파일은 휴대 전화의 손 영향에 대한 연구에 유용하게 이용될 수 있을 것으로 본다. Interest of the hand effect on the electromagnetic wave are internationally increasing with the increase of the use of the mobile phone. IEC TC106(International Electrotechnical Commission, Technical Committee 106) promotes international research exchange program in order to reflect the effect of human hands in the standard assessment method of human exposure dosimetry by the electromagnetic wave of mobile phones. Since current commercialized hand phantom is manufactured by taking into account the average size of westerners and provides only one grip posture, it imposes many restrictions on the accurate SAR measurement. Therefore, the development of proper hand phantom accounting for domestic situation and various grip posture capability is essential in order to analyze the accurate effect of human hand on the exposure estimation. In this paper, a jelly hand phantom suitable for Korean was manufactured with various grip posture capability at 835 MHz and 1,800 MHz bands. Although the tolerances of permittivity and conductivity of the manufactured hand phantom are with <TEX>${\pm}10%$</TEX> each, it was much less than CTIA(Cellular Telecommunication Industry Association) tolerance of <TEX>${\pm}20%$</TEX> at both bands. Its 3D CAD(3 Dimensional Computer Aided Design) file which was developed can be utilized for the simulation of human hand effect on SAR measurement of mobile phones. The findings in this study can be utilized for the analysis of human hand effect on SAR measurement of a mobile phone.

Insolvency modeling in the cellular telecommunication industry

In this article, we test several models (decision tress and neural networks) to predict customer insolvency at one of the cellular telecommunication operator in Poland. In comparison to previous studies on customer insolvency, our research presents novelty in the following areas. First of all, we deal with cellular telecommunication customers who use services without paying dues (the literature show the studies that dealt mainly with fixed line operators or banking industry). Secondly, we have a large dataset with 205 explanatory variables derived from the database (previous studies dealt with smaller datasets). Thirdly, we test the quality of the models three months after the estimation with lift and ROC curves to assess the models performance over the time.The main findings from the research are twofold: (1) artificial neural networks perform well when modeling the customer’s insolvency and the best model can capture significant amount of money owed by insolvent customers; (2) decision trees get old quickly and their performance decrease over the time in the top percentiles of the score.

Churn models for prepaid customers in the cellular telecommunication industry using large data marts

In this article, we test the usefulness of the popular data mining models to predict churn of the clients of the Polish cellular telecommunication company. When comparing to previous studies on this topic, our research is novel in the following areas: (1) we deal with prepaid clients (previous studies dealt with postpaid clients) who are far more likely to churn, are less stable and much less is known about them (no application, demographical or personal data), (2) we have 1381 potential variables derived from the clients’ usage (previous studies dealt with data with at least tens of variables) and (3) we test the stability of models across time for all the percentiles of the lift curve – our test sample is collected six months after the estimation of the model. The main finding from our research is that linear models, especially logistic regression, are a very good choice when modelling churn of the prepaid clients. Decision trees are unstable in high percentiles of the lift curve, and we do not recommend their usage.

The application of real option valuation techniques in the cellular telecommunication industry in South Africa

The purpose of this paper is to examine whether real option valuation techniques can be used by cellular telecommunication operators in South Africa when making capital investment decisions in next-generation service-orientated architectures. Prior studies, in other parts of the world, recommend the use of real option valuation techniques by telecommunication operators when conducting capital budgeting. In this study, both Black-Scholes and Binomial models are used to examine their effectiveness in valuing capital investments within a cellular telecommunication industry in South Africa. Results show that real option valuation techniques are effective in analysing investments in cellular telecommunication industry. Their strengths are mostly demonstrated when determining the value of strategic options that are added to traditional (base-case) net present value. Summary and conclusions are provided.

Monitoring Urban Freeway Incidents by Wireless Communications

The efficacy of the driver-initiated incident detection system was assessed by modeling the use of new communications technologies to mitigate problems that beset current cellular call-in programs, problems such as insufficient information on incident location, false reporting, and duplicate calls. An analytical model supported by field data for several important variables was used to determine the system performance measures, that is, the detection rate, mean time to detect, and false alarm rate. The results indicate that with the implementation of new technologies that lead to the automatic geolocation of the driver initiating an incident call, the driver-initiated detection system is effective. The system achieved good detection rates and faster detection times across all simulated incidents occurring under variable traffic flow rates that ranged from light traffic to congested traffic. For instance, even when the proportion of drivers with cellular phones was 1 out of 10, with only 10 percent of them willing to use their phones to report the incidents, close to 80 percent of the incidents were detected within 2 min. This result is consistent with the results of the field studies and shows that even better detection performance can be achieved if current levels of cellular phone ownership in the United States are considered and if drivers’ reporting propensity is raised. It is noteworthy that the Cellular Telecommunications Industry Association reported that there was one cellular phone user per two licensed drivers in the United States at the end of 1999.

Specific absorption rates (SARs) induced in head tissues by microwave radiation from cell phones

The cellular/mobile phone industry has been reluctant to disclose SAR values to the public in the past. The decision by the Cellular Telecommunication Industry Association (CTIA) to require manufacturers to disclose SARs emerged after it became clear that SAR information was going to appear on the FCC Web site in a user-friendly form. It was also prompted by a British government panel's call, on May 11, 2000, for the SAR of each mobile phone to be printed on the box in which the phone is sold. The wireless telephone industry is concerned about how the public may use the SARs, because, according to one industry source, "SARs by themselves may be misleading and variations in SARs do not represent a variation in safety." Indeed, SAR values can vary as a function of the carrier frequency-for example, 850 or 1900 MHz, used to transmit the telephone message-or how the handset is held. The article presents some insights into SAR, what it is, how is it determined, and what it means.
