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...

The popularity and evolution of mobile devices like laptops, mobile phones and Personal Digital Assistants (PDA), and the evolution of fast mobile networks in the last decade, have made it possible to increase the complexity of mobile applications and services provided to end-users. It is also a spectacular growth in multimedia communication especially via the World Wide Web. This paper explore...

In this work we describe the design and implementation of a system, which uses the wireless GSM Short Message Service data transfer technology, in order to give network managers access to services on remote network equipment, via a cellular phone. First, we present the mechanism and discuss the features and restrictions of the Short Message Service, as well as the limitations of current cellula...

Background: Infertility is defined as inability to conceive after a year of sexual intercourses without the use of contraceptives. In half of the cases the causative factor is the male. Males are exposed to the effect of various environmental factors, which may decrease their reproductive capabilities. Phone electromagnetic power is very small, only a few hundredths of a microwave oven, but bec...

introduction : the fast-growing telecommunication and wireless technologies has led to more dependence to these communication devices and higher levels of exposure to electromagnetic radiations propagated by cellular devices and their service towers. to disable signaling in places where silence is valued or where information quarantine measures are required, mobile phone jammers emit radiofrequ...

Background In addition to their widespread applications in various fields, cellular phones have some inappropriate social consequences, including psychosocial addiction, degradation of values, reduced social interactions, early maturity and endangering the psychological...

This paper presents a prototype wireless remote glucose monitoring system interfaced with a ZnO nanowire arrays-based glucose sensor, glucose oxidase enzyme immobilized onto ZnO nanowires in conjunction with a Nafion® membrane coating, which can be effectively applied for the monitoring of glucose levels in diabetics. Global system for mobile communications (GSM) services like general packet ra...

Today, smart phones based on different mobile communication technologies such as GSM, GPRS/EDGE, 3G, 4G, 5G and 6G have become an indispensable element for various services communication, entertainment, banking. In this context, determining the base station power level is important in terms of limit values public health, especially places with high density. study, electromagnetic density 31 sta...

Mobile computing is a domain in great expansion. Wireless networks (GSM, satellite, etc) and Portable Information Appliances PIAs (laptops, PDAs, cellular phones, etc) are developing very rapidly. More and more mobile users would like to execute their applications with the same quality of service as on their desktop station, whatever their needs in memory and computing power. Using such applica...
