The first-generation mobile computing enabled analogue voice and no data, the second-generation enabled digital voice and some data the third-generation will enable digital voice and high-speed data, the fourth-generation should enable IP based voice and multimedia data. Then fifth-generation...

Multiple mobile phone (M²P) usage has become an increasing practice in Nigeria but little is known about the factors propelling it or related communication processes. An examination of its operations reveals interaction with economic and social factors for reduction in call costs and management...

The question addressed is whether the EC has competence under Article 95 EC Treaty1 (EC) on the approximation of laws to allocate the frequencies to be released by the switchover from analogue to digital at the European level, or if the exercise of this legislative power is reserved to the...

This paper studies the impact of information and communication technologies (ICT), especially mobile phone rollout, on economic growth in a sample of African countries from 1988 to 2007. Further, we investigate whether financial inclusion is one of the channels through which mobile phone...

Radio spectrum is a vital asset and resource for mobile network operators. With spectrum in the 800 and 900 MHz bands coverage can be provided with fewer base station sites compared to higher frequency bands like 2.1 and 2.6 GHz. With more spectrum, i.e. wider bandwidth, operators can offer...

Next generation access networks (NGAN) will support a renewed electronic communication market where main opportunities lie in the provision of ubiquitous broadband connectivity, applications and content. From their deployment it is - much - expected a wealth of innovations. Within this framework...

This paper analyses the marginal value of spectrum which includes engineering and strategic value. The analysis of the engineering value shows that operators that are able to obtain more spectrum than their competitors, and pursue network sharing and spectrum aggregation have a competitive...

This paper demonstrates how stated-preference methods can be applied for modelling consumers' preferences in mobile telecommunications, and for measuring network effects. This will be illustrated with a case study of mobile phone operators in Poland. A random parameters multinomial logit model...

In this paper, we examined the reliability of Funtone software and its impact on quality service to the user. As Global System for Mobile (GSM) software is relatively new in the market and the level of awareness of its quality service is low; the need for quality assessment of these services...
