The purpose of this paper is to explain the determinant factors of switching behavior in the Thai cellular market before the Mobile Number Portability (MNP) policy is implemented.

A binary logit model and individual survey data from the National Telecommunications Commission 2009 are used to estimate the intention of mobile phone consumers to switch.

The results show that subscriber characteristics, including age, government officer, self‐employed, internet use, central region, and southern region, are significant in explaining the switching behavior of Thai mobile subscribers. They also indicate that the mobile operators' customers are confronted with different switching costs. The subscribers of the largest mobile operator have the highest switching costs. This study also shows that the largest mobile operators will gain more switching subscribers than smaller operators. The implementation of MNP will help to lower the switching costs of smaller mobile operators rather than of larger operators, as the subscribers of smaller operators are more likely to switch and move to larger mobile operators, as the larger operators provide better quality network coverage. The study shows that the expected impact of implementing MNP without national mobile roaming regulations would be worse for smaller mobile operators. The smaller operators need to compete on both price and quality improvement. In the short run, it would not be possible for the smaller operators to compete with the larger operators due to the inequality in the quality of network coverage.

The result is useful to developing countries considering implementing MNP regulation.

The purpose of this paper is to ascertain the effects of structural and bonding attachment on brand loyalty. The authors identified network quality, network coverage and mobile number portability (MNP) as structural elements of attachment that affect brand loyalty. Similarly, the authors identify brand trust and social interaction ties as elements of bonding-based attachment that affects brand loyalty.

The authors employed a survey as the research design. There were 500 respondents who were customers of telecommunication network brands in Ghana. Data collected were analyzed using the partial least square approach to structural equation modeling (PLS-SEM) on SmartPLS 3.

The findings indicate that structural and bonding-based attachments affect the brand loyalty. Specifically, the authors found that network coverage, network quality, brand trust and social interaction ties have positive effects on brand loyalty while MNP has a negative effect on brand loyalty.

This study conceptualizes attachment from both structural and bonding perspectives, which are rare in the marketing literature. Thus, this study advances the conceptualization of attachment in the marketing literature.

Network coverage is crucial for the adoption of advanced Smart Home applications. The commonly used log-based path loss model is not able to accurately estimate WiFi signal strength in different houses, as it does not fully consider the impact of building morphology. To better describe the propagation of WiFi signals and achieve higher estimation accuracy, this paper studies the basic building morphology characteristics of houses.

A new path loss model based on a decision tree was proposed after measuring the WiFi signal strength passing through multiple housing units. Three types of regression models were tested and compared.

The findings demonstrate that the log-based path loss model fits small houses well, while the newly proposed nonlinear path loss model performs better in large houses (area larger than 125 m2 and area-to-perimeter ratio larger than 2.5). The impact of building design on path loss has been proven and specifically quantified in the model.

Proposed an improved model to estimate indoor network coverage. Quantify the impacts of building morphology on indoor WiFi signal strength. Improve WiFi signal strength estimation to support Smart Home applications.

Wireless sensor networks are expected to be an integral part of any pervasive computing environment. This implies an ever‐increasing need for efficient energy and resource management of both the sensor nodes, as well as the overall sensor network, in order to meet the expected quality of data and service requirements. There have been numerous studies that have looked at the routing of data in sensor networks with the sole intention of reducing communication power consumption. However, there has been comparatively little prior art in the area of multi‐criteria based routing that exploit both the semantics of queries and the state of sensor nodes to improve network service longevity. In this paper, we look at routing in sensor networks from this perspective and propose an adaptive multi‐criteria routing protocol. Our algorithm offers automated reconfiguration of the routing tree as demanded by variations in the network state to meet application service requirements. Our experimental results show that our approach consistently outperforms, in terms of Network Lifetime and Coverage, the leading semantic‐based routing algorithm which reconfigures the routing tree at fixed periods.

The miniscule wireless sensor nodes, engaged in the wide range of applications for its capability of monitoring the physical changes around, requires an improved routing strategy with the befitting sensor node arrangement that plays a vital part in ensuring a completeness of the network coverage.

This paves way for the reduced energy consumption, the enhanced network connections and network longevity. The conventional methods and the evolutionary algorithms developed for arranging of the node ended with the less effectiveness and early convergence with the local optimum respectively.

The paper puts forward the befitting arrangement of the sensor nodes, cluster-head selection and the delayless routing using the ant lion (A-L) optimizer to achieve the substantial coverage, connection, the network-longevity and minimized energy consumption.

The further performance analysis of the proposed system is carried out with the simulation using the network simulator-2 and compared with the genetic algorithm and the particle swarm optimization algorithm to substantiate the competence of the proposed routing method using the ant lion optimization.

The purpose of this study is to investigate the use of global system for mobile communications (GMS) at the University of Ibadan, Nigeria, emphasizing the nature and characteristics of the activities for which it is used, the factors that promote or beset its use, its benefits and the quality of services provided by the operators.

The study adopted a descriptive survey design. A two‐stage stratified sampling technique was adopted for selecting a sample of 456 staff and students of the University of Ibadan that form the target population. The questionnaire was the main data collection instrument while frequency and percentage distributions were the analytical tools adopted.

Findings show a significant use of the GSM for social activities (getting in touch with friends and relations) while its use in research and academic activities was less significant. Also a number of inhibitors of effective GSM use in the University of Ibadan such as limited network coverage, unstable network and difficulty in making calls, etc. were identified.

This study, apart from throwing light on the patterns of the use of GSM in the University of Ibadan, serves as a guide to policy makers to review the policy on telecommunications so as to allow for more and more competitors to engage in the telephony service. The study recommends that the government need to promote a competitive mobile phone market for more players to come into the sector and an upgrade in the communication standard for better GSM services in Nigeria.

Physicians who are primary care providers in rural communities form an essential stakeholder group in rural mobile health (mHealth) delivery. This study was exploratory in nature and was conducted in Udupi district of Karnataka, India. The purpose of this study is to examine the perceptions of rural medical officers (MOs) (rural physicians) regarding the benefits and challenges of mobile phone use by community health workers (CHWs).

In-depth interviews were conducted among 15 MOs belonging to different primary health centers of the district. Only MOs with a minimum five years of experience were recruited in the study using purposive and snowball sampling. This was followed by thematic analysis of the data collected.

The perceptions of MOs regarding the CHWs' use of mobile phones were largely positive. However, they reported the existence of some challenges that limits the potential of its full use. The findings were categorized under four themes namely, benefits of mobile phone use to CHWs, benefits of mobile phone-equipped CHWs, current mobile phone use by CHWs and barriers to CHWs' mobile phone use. The significant barriers reported in the CHWs' mobile phone use were poor mobile network coverage, technical illiteracy, lack of consistent technical training and call and data expense of the CHWs. The participants recommend an increased number of mobile towers, frequent training in mobile phone use and basic English language for the CHWs as possible solutions to the barriers.

Studies examining the perceptions of doctors who are a primary stakeholder group in mHealth as well as in the public health system scenario are limited. To the authors’ knowledge, this is one of the first studies to examine the perception of rural doctors regarding CHWs' mobile phone use for work in India.

This paper aims to answer the following two questions: What are the affecting factors of platform leadership? How do the business ecosystem and unique attributes of platform enterprises affect the formation of platform leadership?

Based on the niche theory, this study used the grounded theory research methods to explore the strategic behavior of platform enterprises, analyze the characteristics of platform leadership and systematically explore the influencing factors of platform leadership based on four internet platform enterprises and their business ecosystem.

The result shows that the acquisition of platform leadership is closely related to the platform enterprises’ Niche, where they are located in the business ecosystem. Platform enterprises play the roles of the founder, coordinator, leader and arranger in the ecosystem, and there are four affecting factors of platform leadership: architecture foundation, connection and coordination, innovation leading and integrated expansion. The architecture foundation consists of four factors: platform architecture, installation base, intellectual property and network coverage; the connection and coordination contain five factors: interactive collaboration, multilateral user connection, information matching, neutral arbitration and mutualism; the innovation leading is composed of four factors: research and development investment, common components, complementary innovation, cross-border search and standard-setting; the integrated expansion includes resource orchestration, modular design, data collaboration, supportive enabling and scenario application.

This research constructs a framework of platform leadership with the influencing factors.

The purpose of this paper is to provide evidence-based policy recommendations for improving the implementation of universal service funds (USF) with a view to closing the digital divide in Africa.

The paper adopts a qualitative approach that draws examples from various African countries supported by 25 interviews from key stakeholders with hands-on experience and roles that shape telecommunications policy in Africa and other developing countries.

The study's findings point out that institutional voids which characterize several African countries inhibit the effectiveness of USF in African countries. The authors identify several institutional and organisational factors and explain how they negatively affect the performance of USF. The authors find that in order to overcome these obstacles, there is a need for a clear redefinition of Universal Access and Service (UAS) policies, restructuring the governance of USF, encouraging cross-sectoral collaborations, and bottom-up initiatives to bridge the digital divide in African countries.

The paper contributes to the underexplored USF literature by shedding light on the role of institutional factors in determining the success of USF. The paper thus complements and provides a different perspective on promoting digital inclusion in Africa from the viewpoint of institutional voids, bringing new insights into the existing literature on how to deal with an intractable area of UAS policy and the wider digital divide debate in developing countries.

The purpose of this paper is to explore the causal relationship between service quality dimensions and overall service quality, and to identify service quality gaps as experienced by the subscribers of the mobile services of Ethiopian Telecommunication Corporation (ETC).

The seven modified dimensions of SERVQUAL, namely tangibles, reliability, responsiveness, empathy, assurance, network aspect, and convenience were used to measure customers' perceptions and expectations of mobile telecommunications services by drawing a sample of 220 respondents using stratified random sampling.

Overall service quality of mobile communications was perceived to be as below average by over half (52.7 percent) of the respondents, followed by less than one‐third (28 percent) who mentioned it as average, and about one‐fifth (19.3 percent) as above average. The highest service quality gap was reported with the added dimension of network aspect, while the lowest score obtained was for convenience. Finally, two regression models predicting overall service quality with reliability and network aspect dimensions were obtained.

The scope (geographical) of the study is limited to the subscribers of mobile services of Addis Ababa (capital city of Ethiopia).

Data representing customer perceptions and expectations with mobile services in delivering quality have been used to identify (in terms of quality gaps) areas needing improvement. ETC should concentrate on providing superior reliability, particularly, accuracy and dependability in mobile services. An extended focus on the items of network aspect dimension (transmission quality and network coverage) is also helpful in improving customers' perceived quality of mobile services.

Since most quality features in the SERVQUAL scale are related with customer handling, this study incorporated, and investigated further, the added two dimensions of network aspect and service convenience for their contribution to overall service quality of mobile communications.
