Factors influencing the adoption of mobile commerce applications in Cameroon

As smartphone penetration continues to double in Sub-Saharan Africa, many businesses are looking into this channel for conducting their business activities. In Cameroon, all the top e-commerce giants have deployed smartphone applications to facilitate m-commerce activities. However, little is known about the factors that influence m-commerce adoption in the country. As such, this study had as objective to determine the key factors that influence consumer’s adoption of m-commerce applications in Cameroon. Using data from 372 respondents, a modified version of the extended unified theory of acceptance and use of technology (UTAUT2) was validated in the Cameroon context. The findings showed that social influence, facilitating conditions, hedonic motivations, perceived risk and perceived trust were significant predictors of the behavioural intention to adopt m-commerce applications. Also, the results showed that consumers who had a high intention to adopt m-commerce were more likely to recommend the technology to others. For researchers, the study depicts the relevance of extending existing technology acceptance models like the UTUAT2 with appropriate factors in different technological and geographical context. For practitioners, the study identifies customer-specific and environmental factors that m-commerce providers in Cameroon and other regions with similar characteristics could consider when designing and implementing strategies for attracting consumers to use their m-commerce applications.

Barriers and drivers in the adoption of current and future mobile services in Finland

Finland has long been seen as the most successful country in Europe in terms of the adoption and use of advanced mobile services. In this paper we discuss the importance of understanding the role of (physical, cognitive, security and economic) barriers and benefits (perceived entertainment value and perceived flexibility) of mobile services as well as the role that functional differences of mobile service bundles play in the process of actual and future use of these bundles. Based on a survey we test six models for mobile travel service bundle, GPRS bundle, mobile surveillance bundle, traditional and more advanced entertainment bundles and m-commerce service bundles. Our analysis shows that understanding the actual and future use is only possible when the subtleties of the specific bundles, i.e. the characteristics of the involved services, are taken into account. Differences in technology or service attributes based on technology cannot be treated as neutral.     

Consumer behaviour in the mobile telecommunications’ market: The individual’s adoption decision of innovative services

Research in the adoption of innovative services in mobile communications markets has not offered a comprehensive explanation of how the individual makes a choice. This article proposes a theoretical framework for the analysis of the adoption decision of innovative mobile services such as mobile TV. The decision to adopt the service can be viewed as a choice based on two cognitive processes of reasoning and referencing, as postulated in behavioural decision making. The framework has both theoretical and practical value. From a theoretical perspective, it illustrates the manner in which referencing and reasoning influence the individual’s decision to adopt innovative services in the mobile telecommunications market. From a practical perspective the framework offers a market analysis tool which can generate useful insights for the vendors.     

Investigating the determinants of low adoption of tablet PCs in Korean firms: Effects of value perception and alternative attractiveness

Many IT innovations show significantly different results from the expectations or market forecasts in the diffusion perspective. Tablet PCs have gained immense attention as useful devices for improving productivity and enhancing customer relationship in firms. However, the diffusion of tablet PCs in firms has been progressing slowly. This study examines the effects of value perception and alternative attractiveness on the diffusion of tablet PCs, using survey data from Korean firms. The results reveal that perceived low benefits, monetary and non-monetary sacrifices are determinants of perceived low value, which in turn influences low adoption intention of tablet PCs. Alternative attractiveness is also significantly associated with perceived low value and low adoption intention. Furthermore, firm innovativeness moderates the relationship between perceived low value and low adoption intention. We discuss the theoretical implications on the adoption barriers of firms from the value adoption model and suggest practical implications for successful diffusion of IT innovations in firms, focused on tablet PCs.

A discussion of some of the issues facing the regulator in dealing with the newly developing nomadic services including HIPERLAN

HIPERLAN is a new standard for nomadic computer equipment being developed by ETSI. The practicalities of licensing of such computer networks make it unlikely that there will be an individual licensing scheme. Nomadic equipment cannot be restricted to certain regions or countries. There are clear indications that it will play an increasingly large role in communications. The best solution to the issue of nomadic equipment and its future development would appear to be an international effort at spectrum planning and frequency allocation.
