To allow for wireless communications among a specific geographic area, base stations of communication network must be deployed to allow sufficient radio coverage to every mobile users. The base stations, successively, must be linked to a central hub called the MSC (mobile switching centre). The mobile switching centre allow connectivity among the PSTN (public switched telephone network) and the...

The accurate reading of a customer water-meter is important as it is the main revenue base for the water authorities. The traditional data collection process is still common in developing countries despite the inherent inefficiency, inaccuracy and labour intensity. A solution to improvement could be based on sensor and communication technology. In this research an automatic water meter reading ...

understanding the antecedents and consequences of customer satisfaction in the mobile communications market is important. this study explores the effects of service quality, trust and perceived value on customer satisfaction, which, in turn, affects continuance intention of mobile services. service quality and customer satisfaction were measured by multiple dimensions. a research model was deve...

The standardisation work of GSM-based systems has its roots in the 1980s, when a standardisation body ‘Groupe Special Mobile’ (GSM)1 was created within the Conference Europeenne des Postes et Telecommunications (CEPT), whose task was to develop a unique digital radio communication system for Europe, at 900 MHz. Since the early days of GSM development, the system has experienced extensive modifi...

Global System for Mobile (GSM) is a second generation cellular standard developed to cater voice services and data delivery using digital modulation. Short Message Service (SMS) is the text communication service component of mobile communication systems, using standardized communications protocols that allow the exchange of short text messages between mobile phone devices. SMS framework allows ...

In this paper, a discussion of employing Global Positioning System (GPS) and geographic information system (GIS) technologies for packet routing strategies in ad hoc mobile wireless networks is presented. Mobile network architectures and existing packet routing schemes are briefly discussed to illustrate how GPS and GIS techniques can be beneficially employed. Telegeoinformatics, a new discipli...

the computer industry has defined the ieee 802.16 family of standards that will enable mobile devices to access a broadband network as an alternative to digital subscriber line technology. as the mobile devices join and leave a network, security measures must be taken to ensure the safety of the network against unauthorized usage by encryption and group key management. ieee 802.16e uses multica...

The world of telecommunications, especially mobile communications, continues to evolve with innovative technologies and high-speed data services. In many economies, mobile phones have overtaken fixed lines. In this dynamic context, we have envisaged to study mobile communication diffusion in Germany and India, from a historical comparative perspective. The basic standard for comparison has been...

There area lot of mobile computer devices with a variety of applications and users Tend to use them more. Due to the limitations of mobile devices, running most of the procedures are impossible. To resolve this problem, mobile devices can be connected to the grid, to use the facilities of grid. On the other hand the communication mechanisms are different for each device and they cannot be c...
