This paper presents the development of GSM-based control home appliances for smart home system. The main aim of the prototype development is to reduce electricity wastage. GSM module was used for receiving short message service (SMS) from user’s mobile phone that automatically enable the controller to take any further action such as to switch ON and OFF the home appliances such as light, aircon...

Mobile communication is an essential part of our daily lives. Therefore, it needs to be secure and reliable. In this paper, we study the security of feature phones, the most common type of mobile phone in the world. We built a framework to analyze the security of SMS clients of feature phones. The framework is based on a small GSM base station, which is readily available on the market. Through ...

BACKGROUND There are about 1.6 billion GSM cellular phones in use throughout the world today. Numerous papers have reported various biological effects in humans exposed to electromagnetic fields emitted by mobile phones. The aim of the present study was to advance our understanding of potential adverse effects of the GSM mobile phones on the human hearing system. METHODS Auditory Brainstem Re...

BACKGROUND AND AIMS To observe the effects of mobile phone use in the vicinity of medical devices used in a critical care setting. SUBJECTS AND METHODS Electromagnetic interference (EMI) was tested by using two types of mobile phones - GSM and CDMA. Mobile phones were placed at a distance of one foot from three medical devices - syringe pump, mechanical ventilator, and the bedside monitor - i...

In this paper, we consider problem of positioning of mobile phones, different approaches were produced for these targets using GPS, WiFi, GSM, UMTS and other sensors, which exist in today smart phone sensors. Location awareness in general is emerging a tremendous interest in different fields and scopes. Position is the key element of context awareness. However GPS produces an accurate position,...

PURPOSE To analyze the short-term effects of radiofrequency radiation (RFR) exposure on genomic deoxyribonucleic acid (DNA) of human hair root cells. SUBJECTS AND METHODS Hair samples were collected from eight healthy human subjects immediately before and after using a 900-MHz GSM (Global System for Mobile Communications) mobile phone for 15 and 30 min. Single-strand DNA breaks of hair root c...

background , despite numerous studies over a decade, it still remains controversial about the biological effects of rf emf emitted by mobile phone telephony. objective , here we investigated the effect of 900 mhz gsm on the induction of oxidative stress and the level of intracellular reactive oxygen species (ros) in human mononuclear cells, monocytes and lymphocytes as defence system cells. met...

today, mobile phone as one of manifestations of new communication technology plays an important role in human individual and social life and it is included an inseparable part in their daily relations so that we can claim that life is impossible without it for many of people or at least it doesn't have any desirability. the influence of mobile phone applications in life different matters, ...

Now-a-days, a lot of research is being carried out in the development of USVs (Unmanned surface vehicles), UAVs (Unmanned Aerial Vehicles) etc. Now in case of USVs generally, we have seen that wireless controlled vehicles use RF circuits which suffer from many drawbacks such as limited working range, limited frequency range and limited control. Moreover shooting infrared outdoors on a bright su...

<span>Security <span>is very apart important for vehicles to prevent the injury as vehicle theft is common phenomenon now a days. We can ensure security of our via monitoring 24/7. There are many possible ways track vehicle. A few groups do not concern about users need. Our research tracking according user’s demand. concerning on low budget, better geographic coordinate and easy use...
