The continuously use of mobile phone can be attributed to it can use in any places and thus have become one of the most widely used devices in mobile communication which makes it so important in our lives. The convenience and portability of cellphones has made it possible to be carried everywhere. e.g Churches, lecture halls, medical centers etc. Its benefit can create disturbance in some places when there is continuous beeping or ringtones of cell phones which becomes annoying when such noise is disturbance in areas where silence is required or the use or of mobile phone is restricted or prohibited like Libraries and Study rooms A mobile phone jammer is an instrument used to prevent cellular phones from receiving signals from base station. It is a device that transmit signal on the same frequency at which the GSM system operates, the jamming success when the mobile phones in the area where the jammer is located are disabled. The mobile phone jammer unit is intended for blocking all mobile phone types within designated indoor areas. The mobile Phone Jammer is a 'plug and play' unit, its installation is quick and its operation is easy. Once the mobile Phone Jammer is operating, all mobile phones present within the jamming coverage area are blocked, and cellular activity in the immediate surroundings (including incoming and outgoing calls, SMS, pictures sending, etc.) is jammer. This paper focuses on the design of a cell phone jammer to prevent the usage of mobile communication in restricted areas without interfering with the communication channels outside its range.

Harmful Effects

Abstract Mobile phones have been increasingly used in the past decade and have become a cultural instrument. There is a great concern over the harmful effects of electromagnetic and radiofrequency waves as well as microwaves generated by mobile phones and their telecommunication stations on health. The saliva plays an important role in preserving oral homeostasis as the first defensive line against the microbial invasion which protects oral mucosa mechanically and immunologically. A search was run in Pub med, Goggle Scholar, Medline, and Web of Science databases using the following keywords: cell phone, mobile phone, antioxidant profile, saliva, oxidative stress, interleukin, and inflammation. Sixty-five published articles were identified. Studies on the use of cell phones as educational aids, the use of immune histochemistry on salivary glands, or the evaluation of saliva in individuals with specific conditions, such as the use of orthodontic brackets, were excluded. In addition, duplicate articles are eliminated, and finally, 14 articles were included in the present study. Nowadays mobile phone is very popular, causing concern about the effect it has on people’s health. Parotid salivary glands are in close contact with a cell phone while talking with the phone and the possibility of being affected by them; so this study was designed to investigate the effect of cell phone use on salivary components.

Positive Results

The possibility that using a cell phone could cause brain cancer first arose in the early 1990s and has been the subject of research since then. Radiofrequency waves used in cellular communications are far too weak to induce cancer by any known mechanism, and most scientific and regulatory bodies have found the evidence for health effects from use of mobile phones to be unconvincing. Nevertheless, positive results, largely from a single group of researchers, and an ambiguous assessment from single agency have kept the controversy alive. New studies are in progress.

Quick Response

Today by extensive use of intelligent mobile phones, increased size of screens and enriching the mobile phones by Global Positioning System (GPS) technology use of location based services have been considered by public users more than ever.. Based on the position of users, they can receive the desired information from different LBS providers. Any LBS system generally includes five main parts: mobile devices, communication network, positioning system, service provider and data provider. By now many advances have been gained in relation to any of these parts; however the users positioning especially in indoor environments is propounded as an essential and critical issue in LBS. It is well known that GPS performs too poorly inside buildings to provide usable indoor positioning. On the other hand, current indoor positioning technologies such as using RFID or WiFi network need different hardware and software infrastructures. In this paper, we propose a new method to overcome these challenges. This method is using the Quick Response (QR) Code Technology. QR Code is a 2D encrypted barcode with a matrix structure which consists of black modules arranged in a square grid. Scanning and data retrieving process from QR Code is possible by use of different camera-enabled mobile phones only by installing the barcode reader software. This paper reviews the capabilities of QR Code technology and then discusses the advantages of using QR Code in Indoor LBS (ILBS) system in comparison to other technologies. Finally, some prospects of using QR Code are illustrated through implementation of a scenario. The most important advantages of using this new technology in ILBS are easy implementation, spending less expenses, quick data retrieval, possibility of printing the QR Code on different products and no need for complicated hardware and software infrastructures.

Our lives have been drastically altered by smart phones. Nowadays, we can't do anything without our phones. We must analyse ourselves or think clearly in order to determine whether a cell phone is a boon or a curse. We are all a part of technoculture. Schoolchildren have also been immersed in this aspect of techno-culture during the previous two years. We must properly prepare technology because each technology has both positive and negative elements. Overuse of mobile phones is extremely dangerous to one's health. Students need to have mobile phone to attend classes from the comforts of their home. Smart phone has become the basic necessity of school children daily life and students are slowly coping with this new method of technology for their academic progress.  Over usage of mobile phone leads to such an extent that children comes across a situation where they cannot live without the use of mobile phone. Such a situation when students start to have fear when they cannot access their smart phones is known has nomophobia. The present study was carried among the school going children in the Surendernagar district of Gujarat. The findings of the study reveal that overall 52.58 % of the study subjects had moderate level of Nomophobia. Around 32.58 % of the study subjects had mild level of nomophobia. 14.40 of the school children had severe level of nomophobia, while only 0.44% had no signs and symptoms of Nomophobia. Mobile phones have lead to disturbance in the family relationship.

Development Of Language

Abstract Over the past 20 years, there have been many advances in the computer industry as well as in augmentative and alternative communication (AAC) devices. Computers are becoming more compact and have multiple purposes, such as the iPhone, which is a cell phone, mp3 player, and an Internet browser. AAC devices also have evolved to become multi-purpose devices; the most sophisticated devices have functionality similar to the iPhone and iPod. Recently, the idea of having the iPhone and iPad as a communication device was initiated with the development of language applications specifically for this format. It might be true that this idea could become the future of AAC devices; however, there are major access issues to overcome before the idea is a reality. This article will chronicle advancements in AAC devices, specifically on access methods, throughout the years, towards the transition to handheld devices. The newest technologies hold much promise with both features and affordability factors being highly attractive. Yet, these technologies must be made to incorporate alternate access if they are to meet their fullest potential as AAC tools.
