GSM (Group Special Mobile or System for Mobile Communications) is the PAN-EUROPEAN standard for digital cellular communication. GSM provides enhanced features when compared with the older analog-based wireless systems. A GSM network is more vulnerable to unauthorized access and eavesdropping when compared with the traditional fixed wired networks due to the mobility of users, the transmission o...

BACKGROUND As the use of mobile phones is increasing, public concern about the harmful effects of radiation emitted by these devices is also growing. In addition, protection questions and biological effects are among growing concerns which have remained largely unanswered. Stem cells are useful models to assess the effects of radiofrequency electromagnetic fields (RF-EMF) on other cell lines. S...

In this paper, we discuss security issues associated with mobile telephone networks and focus on the unique issues that appear due to the mobility of the user. We provide an overview of how some of these issues are addressed in the second-generation mobile network GSM and consider some of the possible shortcomings of that network. We then compare security features in GSM with those implemented ...

0163-6804/97/$10.00 © 1997 IEEE he trends in telecommunications are proceeding with a strong tendency toward increasing need for mobility in the access links within the network. Examples are: • Residential line access with the proliferation of cordless phones (their penetration rate has passed that of fixed phones in the United States, for instance) • Business lines with wireless private branch...

introduction: over the last decade, exposure to non-ionizing electromagnetic waves due to base station antenna has increased. this in vivo study was planned for evaluating the effects of whole-body exposure to 950 mhz field of gsm mobile phone system on rat dentate gyrus long-term potentiation. materials and methods: 24 naive male wistar rats (3 month old, 225|¡|25 g) were randomly divided in t...

Nowadays due to technological advance and its direct impact on the quality of human life, addressing the issue of health and its determinants is very important. Maintaining public health is one of the most fundamental issues in each community. The aim of the study was to survey relationship between dependence on modern communication tools (internet and mobile phones) and psychological well-bein...

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...
