This paper illustrates on an approach to control a mobile robot using DTMF tone through the GSM network. DTMF tones to control a mobile robot are generated by pressing the keypad buttons of a GSM mobile which is counted as remote. The robot receives the tones using another GSM mobile stuck with it. The mobile robot perceives the control tone by using a DTMF decoder IC and a preprogrammed microp...

A novel approach to automatic positioning and communication is presented in this paper. The approach is using single GSM (Global System for Mobile Communication) technology to achieve both positioning of the mobile station and communication with the other parties in a system containing a number of mobile stations. The paper deals with the overall system architecture, and briefly describes the a...

In this paper we detail two algorithms for detecting that a GSM mobile phone is moving (or stationary, since this is when the phone is simply not moving). These algorithms, in early experiments, show excellent promise and require nothing from the mobile phone other than radio signals that the phone must have to perform its normal function. We also discuss our approach to determine not only if a...

The National Institute of Information and Communications Technology (NICT) has been studying a new mobile communication system, named Satellite-Terrestrial Integrated Mobile Communication Systems (STICS)[1]. The STICS is a mobile phone system in which terrestrial mobile and satellite communication systems coexist, and is seamlessly integrated in the same frequency band. We aim for the realizati...

This thesis considers the risk evaluation of microwaves from two important points of view. First, the methodology of the exposure studies elucidating the health effects of mobile phones is considered starting from the general aspects of designing setups and proceeding to the assessment of the exposure level (dosimetry) and practical execution of the experiments. Second, the exposure assessment ...

Standardized in 3GPP as part of the GSM/WCDMA family, EDGE is a simple and cost-efficient upgrade that provides a more than threefold increase in both the capacity and performance of GSM/GPRS networks. EDGE is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM. The structure of EDGE resembles to that of GSM network that enabl...
