This study examines the adoption of Mobile Internet (M-Internet) as a new Information and Communication Technology (ICT) from the value perspective. M-Internet is a fast growing enabling technology for Mobile Commerce. However, despite its phenomenal growth and although M-Internet essentially provides the same services as stationary Internet, its adoption rate in many countries is very low compared to that of stationary Internet. The well-known Technology Adoption Model (TAM) has been used for explaining the adoption of traditional technologies. Most adopters and users of traditional technologies (e.g., spreadsheet, word processor) are employees in an organizational setting who use the technology for work purposes, and the cost of mandatory adoption and usage is borne by the organization. In contrast, adopters and users of M-Internet are individuals who play the dual roles of technology user and service consumer. Most of them adopt and use it for personal purposes, and the cost of voluntary adoption and usage is borne by the individuals. Thus, the adopters of new ICT, especially M-Internet, are also consumers rather than simply technology users. By adopting the theory of consumer choice and decision making from economics and marketing research, this study develops the Value-based Adoption Model (VAM) and explains customers' M-Internet adoption from the value maximization perspective. The findings demonstrate that consumers' perception of the value of M-Internet is a principal determinant of adoption intention, and the other beliefs are mediated through perceived value. The theoretical and practical implications of VAM related to M-Internet are discussed.

Value-based Adoption of Mobile Internet: An empirical investigation

A collaborative Web browsing session may take place over a network, allowing the presenter on a first computer to direct the audio and visual components of a browser on one or more second computers. The second computer is instructed to log into a control site that downloads an active control, such as an applet, to the second computer. The present invention allows a collaborative Web browsing session ('session'), as created by the presenter and witnessed by one or more users on second computers, to be recorded and archived by the control site. When a user of a computer is connected to the control site through a communication network such as the World Wide Web, that user may log into the control site and request to view an archived session. The session will then be replayed by the control site on the user's computer, directing the audio and visual components of the browser on the user's computer as if the user was attending the live session. The recorded session replays the events of the live session in real time such that the playback experience contains the same audio and visual events that took place when the session was originally being recorded.

The purpose of this research was to explore teaching and learning when mobile computing devices, such as cellphones and smartphones, were implemented in higher education. This paper presents a portion of the findings on students' perceptions of learning with mobile computing devices and the roles social media played. This qualitative research study focused on students from three universities across the US. The students' teachers had been integrating mobile computing devices, such as cellphones and smartphones, into their courses for at least two semesters. Data were collected through student focus group interviews. Two specific themes emerged from the interview data: (a) advantages of mobile computing devices for student learning and (b) frustrations from learning with mobile computing devices. Mobile computing devices and the use of social media created opportunities for interaction, provided opportunities for collaboration, as well as allowed students to engage in content creation and communication using social media and Web 2.0 tools with the assistance of constant connectivity.

Output signals are served from a serving device to a plurality of browsing devices connected to a network. The output signals represent commands executable by each browsable device so as to display viewable data in accordance with specified page formatting. Requests from browsing clients are identified which contain information relating to the data itself and the display format for the data. The data is read and processed so as to combine a representation of the viewable data with executable instructions. The signals are then supplied to requesting browsing devices, after effectively being assembled as a real time on-line process.

Advances in e-commerce have resulted in significant progress towards strategies, requirements, and development of e-commerce applications. However, nearly all e-commerce applications envisioned and developed so far assume fixed or stationary users with wired infrastructure. We envision many new e-commerce applications that will be possible and significantly benefit from emerging wireless and mobile networks. To allow designers, developers, and researchers to strategize and create mobile commerce applications, we propose a four-level integrated framework for mobile commerce. Since there are potentially an unlimited number of mobile commerce applications, we attempt to identify several important classes of applications such as mobile financial applications, mobile inventory management, proactive service management, product location and search, and wireless re-engineering. We discuss how to successfully define, architect, and implement the necessary hardware/software infrastructure in support of mobile commerce. Also, to make mobile commerce applications a reality, we address networking requirements, discuss support from wireless carriers, and present some open research problems.

Mobile commerce: framework, applications and networking support

W ith the increasing use of small portable computers, wireless networks, and satellites, a trend to support computing on the move has emerged—this trend is known as mobile computing or nomadic computing [3]. Also referred to as anytime/anywhere computing, mobile computing has several interesting and important applications for business (such as instant claim processing and e-commerce), telecommunications and personal communications, national defense (tracking troop movements), emergency and disaster management, real-time control systems, remote operation of appliances, and in accessing the Internet. Since a user may not maintain a fixed position in such environments, the mobile and wireless networking support allowing mobile users to communicate with other users (fixed or mobile) becomes crucial. A possible scenario may involve several different networks that can support or can be modified to support mobile users. When dealing with different wireless networks, a universal mobile device should be able to select the network (LAN, the Internet, PCS, or satellite) that best meets user requirements. Wireless and mobile networks have provided the flexibility required for an increasingly mobile workforce. As shown in Figure 1(a), the worldwide number of cellular, GSM, and PCS subscribers increased from 140 million in 1996 to over 300 million in 1999 and is expected to grow to 650 million by 2001 (see www.gsmdata.com). In the U.S., capital investment increased from $6.3 billion in 1990 to $66.8 billion in 1999 and service revenues were up from $4.5 billion to $38.7 billion in 1999 (see www.wow-com.com) as shown in Figure 1(b). During the same period, the average local monthly bill diminished from $80 to $39 as shown in Figure 1(c), indicating the technological maturity and the tremendous competition among service providers. Many general remarks can be made about wireless systems. First, the channel capacity typically available in wireless systems is much lower than what is Upkar Varshney and Ron Vetter

Emerging mobile and wireless networks

Electronic commerce continues to see phenomenal growth, but so far most e-commerce development involves wired infrastructures. The authors believe emerging wireless and mobile networks will provide new avenues for growth, creating new opportunities in mobile commerce. According to the GartnerGroup, a market research firm, by 2004 at least 40 percent of consumer-to-business e-commerce will come from smart phones using the wireless application protocol (WAP). Based on a study by the Wireless Data and Computing Service, a division of Strategy Analytics, the annual mobile commerce market may rise to $200 billion by 2004. The authors provide a mobile commerce framework to illustrate potential applications such as mobile inventory management, product location and search, proactive service management, and mobile entertainment. They also describe the wireless user and networking infrastructure, emerging W3C standards, and the open and global WAP specification.

Mobile commerce: a new frontier

We envision many new e-commerce applications will be possible and significantly benefit from emerging wireless and mobile networks. These applications can collectively be termed wireless e-commerce or mobile commerce. To allow designers, developers, and researchers to strategize and effectively implement mobile commerce applications, we propose a 4-level integrated framework for mobile commerce. Since there are potentially an unlimited number of mobile commerce applications we only identify a few important classes of applications such as mobile financial applications, mobile advertising, mobile inventory management, proactive service management, product location and search, and wireless re-engineering. We also address the networking requirements of these applications and discuss how these requirements can be supported by existing and emerging wireless networks. It is our hope that this work will become the framework for further research in mobile commerce.

A framework for the emerging mobile commerce applications

Asynchronous transfer mode (ATM) is often described as the future computer networking paradigm that will bring high-speed communications to the desktop. What is ATM? How is it different from today's networking technologies? This article is intended to acquaint readers with this emerging technology and describe some of the concepts embodied within it. In order to understand why ATM was created and how it works, we first need to review a bit of computer networking history.
