In recent times the cost of mobile communication has dropped significantly leading to a dramatic increase in mobile phone usage. The widespread usage has led mobiles to emerge as a strong alternative for other applications one of which is tracking. This has enabled law-enforcing agencies to detect overspeeding vehicles and organizations to keep track its employees. The 3 major ways of tracking ...
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract The main focus of this paper is to implement the health monitoring system continuously without hospitalization using wearable sensors. Wearable sensors monitor the parameters of the human body like temperature, pressure, heart beat by using sensors...
Global System for Mobile (GSM) is a second generation cellular standard developed to cater voice services and data delivery using digital modulation. Short Message Service (SMS) is the text communication service component of mobile communication systems, using standardized communications protocols that allow the exchange of short text messages between mobile phone devices. SMS framework allows ...
This paper describes the architecture of a face recognition technique for door phone embedded system with interactive face and voice response. for the face recognition method using PCA algorithm. In this paper feature is extracted using PCA. The face recognition system using UVC Driver camera has been considered. The proposed system recognize the persons up to 300 cm and send feedback to mobile...
background: a lot of investigations exist on the biological effects of radiofrequency and microwave radiation however only a few studies have considered non-carcinogenic exposure to radiations specifically from mobile phones. objectives: to introduce some subjective neurological symptoms in mobile phone users. materials and methods: in this cross-sectional descriptive study conducted from march...
The miniaturization of mobile phone antennas by means of purposeful tuning of chassis mode resonances is discussed. A simple approach to antenna independent analysis of chassis mode resonances is introduced. A novel technique for simultaneous tuning of a bar-type phone chassis in two frequency bands is presented. The optimum design and placement of capacitive coupling elements for excitation of...
With the rapid development in global communication networks, the threat of security and in particular that of cellular telecommunication system is real and highly dangerous. Mobile phone and other wireless device usage is increasing daily with ground breaking technological developments – in design, style, content and micro-chips performance. The contents of the multimedia packages – conversatio...
A fter discussing advances in wired networking in a previous column (" Recent Advances in Wired Networking, " Computer , April 2000, pp. 107-109), I now turn to advances in wireless networking. Wireless networks can include everything from cellular, personal communications system (PCS), and Group System for Mobile communications (GSM) networks to wireless LANs, satellite-based networks, and fix...
