Studying effects of mobile phone base station signals on health have been discouraged by authoritative bodies like WHO International EMF Project and COST 281. WHO recommended studies around base stations in 2003 but again stated in 2006 that studies on cancer in relation to base station exposure are of low priority. As a result only few investigations of effects of base station exposure on heal...

The mobile telephone companies are currently rolling out their GSM communications systems throughout Devon. Several people have asked me to write a discussion of the latest research on health problems associated with base stations. This is of particular concern to Devon people because of the highly publicised cancer clusters around the Orange transmitter in Crediton and the shared transmitter i...

Location based services are becoming an emerging market due to technological advances achieved both at GSM phone operators and the multimedia nature of the mobile handsets. In this paper, a new methodology of mobile positioning integrating both GSM network using signal strengths and GPS readings in the light of an assisted GPS based approach. The methodology employs an extended Kalman filter ap...

(Extended Abstract) Later this year we shall see the release of the Third Generation Partnership Project (3GPP) specifications for WCDMA – the first third generation standard for mobile communications. This 3G system combines elements of both a radical departure and a timid evolution from the 2G system known as GSM. It is radically different from GSM in having a wide-band CDMA system for its ai...

The most widely used mobile computing device today is the Mobile phone, can be used not only for voice and data communications but also as a computing device running context aware applications. In this paper we present a model that based on GSM data base. The objective of this paper identifies user groups based on places visited by a user, date, time, longitude and latitude. This information ca...

to date, registered users of mobile phone communication network exceeded from total numbers of the world population, while a little knowledge of the biological effects of, 900-1800 mhz microwave radiation, originating from the handsets or the base transceiver stations, have been released. the current study was designed for evaluation of 900-mhz radiation effects on candida albicans proliferatio...

In response to the demand from a growing number of people concerned about possible impact RF-EMF on health, French National Frequency Agency (ANFR) has published standardized protocol for in-situ measurements radiofrequency electromagnetic fields (RF-EMF). This was based search point highest field strength and use spot measurement. framework an epidemiological study, such were implemented in ho...

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 ...

Context-aware applications have been gaining huge interest in the last few years. With cell phones becoming ubiquitous computing devices, cell phone localization has become an important research problem. Database Correlation Method (DCM) is a positioning technology that based on a database of a premeasured location dependent variable such as Received Signal Strength (RSS). DCM has shown superio...
