The computing power of a third generation mobile telephone is already similar to that of the first personal computers from the mid 1980s or a third generation minicomputer from the early 1970s. In addition, wireless connection speeds can be substantially faster than the fixed-line modem in most home computers. The fact that the mobile telephone is the standard tool, leisure device or fashion ac...

With mobile payment, individuals can buy goods and services through the use of a mobile device and wireless technology. Still, although the usage of mobile payment provides several advantages, such as a more convenient and faster paying-process, it is hardly used. Individuals rather stick with their current payment method, such as cash, EC card or credit card. In this study, we therefore try to...

In contrast to recent US studies showing a decrease in core network size, our Kenyan data reveals substantial network growth. We attribute this to the diffusion of mobile telephones. Results from pooled survey data from Nairobi professionals and entrepreneurs in 2002 and 2007 as well as qualitative interviews from 2007 to 2009 show virtual saturation in the diffusion of phones during this perio...

Vertical restrictions have theoretically ambiguous efficiency effects. Marketplace evidence is therefore required to reveal the presence of anti-competitive foreclosure. The bundling of mobile phones with cellular network service offers one such market test. Two European nations—Finland and Belgium—prohibited tying arrangements for mobile service and mobile devices (handsets) in wireless broadb...

Recently, there has been concern that the use of hand-held cellular telephones may be linked with an increased risk of cancer. In response to this concern, and the rapidly rising number of cellular telephone users worldwide, studies have been conducted to determine whether there is an association between cellular telephone use and an increased risk of certain types of cancer. Although the major...

The expansion of the web has reached outrageous proportions with the number of web communities existing and the number of those being created daily increasing dramatically. To parallel this phenomenon is the trend nowadays of mobile phone services. One of the most representative is the case of Greece, where in a period of five years about five million people subscribed for a telephone number fo...

This paper analyses the pattern and rate of adoption of mobile telephones by the Portuguese population. It is shown that the pattern of diffusion is S-shaped and is consistent with a logistic function, which describes a symmetrical growth process. Furthermore, it is found that about 67 percent of the population will likely adopt mobile phones, and that the levelling-off process in the diffusion...

Rapid diffusion of mobile telephone services is accompanied with low satisfaction and high switching behavior many markets. Despite the popularity of technology diffusion studies in marketing literature, limited research concentrate on the impact of marketing mix variables vis-à-vis clients’ satisfaction. Much fewer studies were conducted in developing nations. This paper investigates the influ...

Everyday things are the things we live with. They are the building blocks of our lifeworlds. Many everyday things are not specifically for work or leisure, as they transcend the borders of many activities. Consider, for instance, the use of telephones: we use them at work to coordinate and communicate, but we also use them to talk to friends and familiy. In the case of mobile phones, this is ev...

There is a need for new usability methods tailored to suit the development of mobile ICT. In response to this, three methods that have been developed to a prototype level are presented. The methods are designed to be cost-effective and provide information on (1) user problems as experienced in users’ everyday lives, (2) contexts of use, and (3) integration of technology in users’ patterns of ac...
