The United Kingdom is witnessing some of the highest volumes of motor vehicle traffic on its roads. In addition, a large number of motor vehicle traffic accidents are reported annually, of which it is estimated that a quarter involve the illegal use of a hand-held mobile device by the driver. Establishing whether mobile phone usage was a causal factor for an accident involves carrying out a for...

Usability has traditionally been a user interface issue that deals with interaction between a system and a user. Mobile handsets are devices that extend the concept of a system to be more than just one device. They are technically complex devices that need a network and services in order to be useful and usable. This paper gives a new perspective to the concept of usability in the context of mo...

This paper presents a procedure for the evaluation of the Electromagnetic (EM) interaction between the mobile phone antenna and human body, i.e., head and hand, and investigates the factors may influence this interaction. These factors are considered for different mobile phone handset models, different form factors and different antenna types, operating in the GSM900, GSM1800/DCS, and UMTS/IMT2...

We study the effect of new product introduction on firm value. Using a unique sample on mobile phone handset introduction by 16 major handset manufacturers over 10 years, we distinguish between imitative product introduction and truly innovative product introduction. We find that while most product introduction is imitative, both types of innovation increase firm value. However, truly innovativ...

Various network technologies have been developed towards ubiquitous computing. Actually, the specific network technology has its own protocol layer, characteristics and objectives. Due to these limitations, though cellular network and WPAN are being used in handset together, the services using both networks are not so popular until now. This paper presents a platform design integrating cellular...

The user’s experience of a mobile communication system entirely depends on the performance of the bidirectional radio link between the base station (BS) and the handset. Each mobile network operator creates a system of linked BSs located to provide coverage of as large a physical area as possible. While the BS will typically be equipped with a relatively large high-gain antenna and a transmitte...

This thesis discusses potential country-specific effects that might explain mobile subscriber behavior in different countries. There are both techno-economic and psycho-socio-cultural factors explaining crosscountry differences. Based on the theoretical framework several hypotheses are presented with regards to possible usage-level observations. The theoretical framework is utilized with a rece...

Much has happened during the last five years on the Finnish mobile communications market. Recent developments include: the introduction of mobile number portability (MNP) in July 2004, the emergence of mobile virtual network operators (MVNOs), price war and hyper-competition followed by consolidation, late deployment of 3G networks, however, with early upgrade to high-speed downlink packet acce...

Over the years, mobile phones have undergone dramatic changes in form, functions, performance, and cost. Evolving new technologies have brought smaller, more energy efficient, and highly integrated semiconductor devices, leading to new levels of portable (mobile) phone integration. While operators are offering additional new services, such as short message service (SMS), multimedia service (MMS...

Mobile technology is getting changed very fast in commensurate with other technological hyper changes. Buyers’ expectation from a new cellular phone is also changing over time. Producers, thereby, have to keep themselves abreast of changes in customer taste and preferences to attract, capture, grow, and retain both existing and potential customers. This study is set to measure factors affecting...
