The Vector Component Analyzer: A New Way to Characterize Distortions of Modulated Signals in High-Frequency Active Devices

Wireless telecommunication technology is evolving fast. Driven by an insatiable demand for higher data rates, the modulated signals that are being transmitted and received over the air and through space are growing in bandwidth and use ever higher carrier frequencies. The 6G visionaries are setting goals of 30 GHz of modulation bandwidth at a carrier frequency of 300 GHz and achieving a mind-boggling data rate of 11 Gb/s. At the heart of this technological evolution of the wireless telecommunications industry are billions of high-frequency active components: amplifiers, mixers, and frequency converters. These active components are necessary for the amplification and frequency conversion of the modulated signals. These components are not perfect, and the modulated signal deteriorates as it passes through the active component semiconductor core.

Analysis of Firms’ Incentives to Control the Standard Development Process

We study how competitive, technological and network incentives influence firms participation behaviour within the standard development process. We focus on firms representing architecture-level and implementer-level positions in the wireless telecommunications industry value chain. We also investigate how the value of a firm’s proprietary technology influences its participation behaviour. We find evidence that firms representing architecture and implementer-level positions are more likely to promote technical features. Furthermore, we find that firms representing the architecture-level and implementer-level positions with more valuable proprietary technology are more likely to promote technical features than their intra-segmental competitors with less valuable proprietary technology. These findings have important implications for the emerging stream of research on standards development organizations.

Static or Dynamic Efficiency: Horizontal Merger Effects in the Wireless Telecommunications Industry

This paper studies five mergers in the European wireless telecommunication industry and analyzes their impact on prices and capital expenditures of both merging carriers and their rivals. We find substantial heterogeneity in the relationship between increases in concentration and carriers’ prices. The specifics of each merger case clearly matter. Moreover, we find a positive correlation between the price and the investment effect; when the prices after a merger increase (decrease), the investments increase (decrease) too. Thus, we document a trade-off between static and dynamic efficiency of mergers.

A Stochastic Approach for Valuing Customers: A Case Study

The more competition among industry participants severe, the more companies try to retain their customers and acquire new customers from their competitors. To gain competitive advantage, many companies are adopting and deploying more refined and sophisticated Customer Relationship Management systems. In the marketing area, a personalized marketing paradigm has already been infiltrated into our lives. To support personalized marketing, it is necessary to identify an individual customer’s true value. Various researches on customer value have conducted under the name of Customer Lifetime Value (CLV), Customer Equity, Customer Profitability, and LifeTime Value. In this paper we present issues of calculating individual customer’s lifetime value to deploy more personalized CRM activities. We propose a new method to calculate individual customer’s lifetime value dynamically. The feasibility of the suggested model is illustrated through a case study of the wireless telecommunication industry in Korea. Data mining techniques are used to predict lifetime value of a customer. Marketing implications will be discussed based on the result of individual CLV.

Causes of Churn in the Wireless Telecommunication Industry in Kenya

Customer turnover is a serious problem in the service sector and especially the telecommunication industry. Churn was tested with many variables which all proved to be of significance to the problem. Unlike all previous research that used quantitative methods, this research used a qualitative, non statistical, in-depth case study method to understand the different causes of the problem and their interlinks. Data was gathered from websites of operators, four interviews with managers of operators, and 26 field interviews with customers using more than one SIM card. The results indicated that the causes are complex and interlinked making it impossible to consider one variable in isolation. Recommendations to operators were based on the need to find alternative solutions that consider the customers’ effect on the problem.

The smartphone patent wars saga: availability of injunctive relief for standard essential patents

Increasingly, holders of so-called standard essential patents for which a FRAND commitment has been made are finding their ability to seek and obtain injunctive relief or similar remedies for patent infringement challenged by developments occurring in major standard-setting organizations, as well as in the actions of competition authorities and courts from various jurisdictions around the globe. The wireless telecommunications industry is a major driver of competitiveness and represents one of the key industrial sectors of the 21st century. Over the past years there has been dynamic growth in the market, from which consumers worldwide have benefited greatly. Today, there are over six billion mobile connections worldwide. This massive increase of connectivity has been accompanied by a shift from basic mobile phones, the functionality of which is limited to voice calls and text messaging, towards high-end smartphones. While smartphones have become a viable alternative to PCs for many users due...

Customer segmentation using unobserved heterogeneity in the perceived-value–loyalty–intentions link

Multiple facets of perceived value perceptions drive loyalty intentions. However, this value–loyalty link is not uniform for all customers. In fact, the present study identifies three different segments that are internally consistent and stable across different service industries, using two data sets: the wireless telecommunication industry (sample size 1122) and the financial services industry (sample size 982). Comparing the results of a single-class solution with finite mixture results confirms the existence of unobserved customer segments. The three established segments are “rationalists”, “functionalists” and “value maximizers”. These results point the way for value-based segmentation in loyalty initiatives and reflect the importance of a multidimensional conceptualization of perceived value, comprising cognitive and affective components. The present results substantiate the fact that assuming a homogeneous value–loyalty link provides a misleading view of the market. The paper derives implications for marketing research and practice in terms of segmentation, positioning, loyalty programs and strategic alliances.

Developing customer churn models for customer relationship management

Customer churn is the term used to describe customers who terminate their relationship with a company. Since churn means a loss of revenue to a company, it is important to identify customer churn and provide incentives to them in order to retain them to the company. This paper aims to design methodologies for the customer churn prediction problem in wireless telecommunications industry. Since the number of features in customer churn dataset is rather large, the performance of decision trees is significantly degraded if inappropriate features are selected and used for building decision trees. This paper finds features that have high effect on customer churn, and to design methodologies that will cope with high dimensionality of dataset and the customer churn prediction problem. This paper provides experimental results of a set of data mining schemes and feature selection methods for customer churn datasets.

Compressed Transport of Baseband Signals in Radio Access Networks

In current wireless base station solutions it is becoming common to physically separate baseband units and radio subsystems. In many wireless technologies this architecture requires allocation of significant transport network resources. In this paper a low-latency baseband signal compression scheme is presented. The compression scheme significantly lowers the transport data rate while maintaining low levels of signal distortion, thus resulting in a lower-cost transport network. Considering the importance of packet-based networks, a number of additional novel compression schemes are proposed. They are optimized for transport networks that implement a quality-of-service (QoS) mechanism and/or multi-link transmission. The compression schemes are parameterized such that a smooth trade-off between the required signal quality and compression performance can be achieved through operator choice of the suitable parameter values. An attractive feature of these schemes is that they can be applied to different wireless technologies, with appropriate parameter settings, without disrupting the present architecture. The proposed solutions will lead to a cost-effective implementation of collocated and distributed network-centric baseband processing, coordinated multi-point (CoMP) and/or distributed antenna system (DAS) which are critical topics for the entire wireless telecommunications industry and infrastructure.

How value and trust influence loyalty in wireless telecommunications industry

Despite making significant investments in enhancing the customer service experience, long-term customer loyalty remains an elusive dream for many service providers. Particularly in the telecommunications industry, switching providers even from within continuous contract relationships is easy and companies struggle to retain their customers. Trust and value are considered cornerstones of long-term relationships, so it is perhaps surprising that previous research on how relationship age and usage level actually affect value, trust and loyalty is inconclusive. The current research is set in the telecommunications services field and draws on a large-scale survey undertaken in Finland. The findings support the contention that perceived value relates positively to loyalty, and that trust mediates that relationship. Surprisingly, in the telecommunications industry, increasing relationship age and usage level strengthen neither value and loyalty nor the links between trust and loyalty. The results may be explained by the unique characteristics of the highly competitive mobile telecommunications sector, and confirm the view that loyalty does not pay without strategies that value long-term customers and thereby build trust with new customers.

Reassessing Tying Arrangements at the End of AT&T’s iPhone Exclusivity

Tying arrangements are common in the wireless telecommunications industry. Wireless networks compete for exclusive contracts to offer popular mobile devices. In January 2011, one of the most notorious exclusivity contracts ended when Apple announced that the iPhone would be available on the Verizon network, ending four years of iPhone exclusivity on AT&T. This long-anticipated move has been hailed as progress for consumer choice and competition in the industry. Such enthusiasm is rooted in the Supreme Court’s enduring stance against tying arrangements–a position that is based on unreasonable goals and illusory harms. This Article examines the Supreme Court’s tying jurisprudence in order to understand the harms that the Court seeks to combat. It then applies that understanding to a context-specific analysis of tying arrangements in the wireless telecommunications industry. In finding that AT&T’s iPhone exclusivity has had significant pro-competitive effects and has fostered innovation in the industry, the Article exposes the misguided basis of the Court’s tying doctrine and argues that it is time to reform the Court’s stance against tying.

Branding and Customer Experience in the Wireless Telecommunication Industry

Growing pains: Pre‐entry experience and the challenge of transition to incumbency

AbstractWe examine how entrepreneurial entry by diversifying and de novo firms in new industries leads to different levels of performance. We propose that these types of firms differ in dynamic capabilities, which help them overcome growth impediments and transition to incumbency in the industry. Growth impediments arise at larger size, older tenure levels in industry, and after technological discontinuities. Because of their prior experience, diversifying firms are better equipped to handle the challenges of impediments to growth. Meanwhile, de novo firms, ostensibly tailor‐made for the targeted industry, are more likely to stumble over these growth challenges, and eventually lag behind diversifying firms. We find support for our hypotheses using a near census of firms in the U.S. wireless telecommunications industry over the 1983–2004 period. Copyright © 2011 John Wiley & Sons, Ltd.

Estimating the switching costs in wireless telecommunication market

PurposeSwitching cost is an important concept in the study of consumer loyalty which has implications for organizational business strategy and regulatory policies. Much research has already examined the formation and influence of switching costs on the consumers' repeated purchase intentions, but little research has focused on quantitative measurement of the switching cost itself. This paper aims to address this issue.Design/methodology/approachBy game theory, a complete Nash‐Bertrand model is proposed to accurately estimate consumer switching costs considering price compensation and transport costs in a duopoly. The relationship between switching costs and market structure is then analyzed by using the example of Hong Kong's wireless telecommunication market. From the observed data of China's wireless telecommunication industry, the model calculates switching costs per year of China Mobile and China Unicom's users respectively, as well as other variables.FindingsThe results demonstrate that reducing consumer switching costs will benefit small operators and increase competition in a winner‐take‐all market.Originality/valueThe model is valuable in calculating unseen switching costs and studying the impact of switching costs on market structure, especially for a duopoly in telecommunication.
