Results of subjective evaluations of perceived sound quality preferences for mobile telephone handsets with different acoustic design strategies are presented and compared to predictions from two objective speech quality metrics.

In this paper I analyze the development and competitiveness of mobile telecommunications industry across the European Union. I estimate a reduced form and structural model of mobile industry using panel data for the EU countries in years 1998-2002. The competitiveness level is significantly influenced by the regulation policy. The regulation implemented throughout the liberalization process of ...

Mobile telephone systems are undergoing a substantial change from voice based systems which also support data transfer to become systems which truly support packet switched data services to mobile subscribers. This evolution towards the third generation (3G) mobile system will be based on the Global System for Mobile communications (GSM) [1] and will begin with the General Packet Radio Service ...

This research solves the problem of maximizing reliability of heterogeneous distributed computing system where random node can fail permanently. The reliability of the system can be achieved by executing all the tasks queued on its node before they all fail. As the mobile network is defined as a dense collection of mobile entities connected by a wireless link, without any administration or fixe...
