Novel Technique

It is often desirable to control mobile phone services in areas where complete silence is either expected or mandatory, including schools, places of worship, hospitals, and prisons. In contrast to conventional techniques, such as jammers or Faraday cages, we present a novel technique to selectively control mobile phone services within a desired area. Our solution enables the area’s keeper to allow mobile phones on a whitelist to freely use mobile services without disruption while denying services to all other mobile phones that are within the boundaries of the desired area to be controlled. Our solution uses a base station controller to identify all mobile devices located within the area to be controlled, while an antenna is placed inside the area to attract all mobile devices in the area to connect to the base station controller. In previous work, we proposed a system that uses directional antennas for the attraction technique. In this work, we show that replacement of the directional antennas with a leaky feeder antenna enables more accurate control of mobile phone services in and around the area to be controlled. Simulations and experiments of the leaky feeder technique confirm its precise control of mobile phone services within the desired areas.

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.

Mobile Phone Usage

As mobile devices increasingly become a ubiquitous and essential part of everyday life, marketers must face a host of new challenges. This new marketing environment requires that marketers understand how consumers use their mobile phones and, more particularly, how they perceive and derive value from doing so. In this article, the authors suggest that mobile services offer either context-related or content-related values. They also explore managerial implications, by revealing factors that influence consumers to utilize mobile phone services.

This chapter surveys and analyzes recent literature on mobile communication to examine its relationship to gender and development, more specifically how women in developing countries use and are impacted by mobile phones. Focusing on issues of power, agency, and social status, the chapter reviews how mobile telephony has been found to be implicated in patriarchal bargaining in different societies, how privacy and control are enabled through it, what benefits have been shown to accrue to women using mobile phones, and what barriers, limitations, and disadvantages of mobile use exist for women and why. The conclusion urges more gender-disaggregated analysis of mobile phone impact and use and offers policy and design recommendations based on the overview and discussion.

The topic of the use of mobile devices and headphones on pedestrian crossings is much less explored in comparison to the use of the mobile phone while driving. Recent years have seen many discussions on this issue, especially in foreign countries. The Slovak Republic, however, has not been giving it enough attention (and it is not mentioned in the National Road Safety Plan for the Slovak Republic from 2011 to 2020). This paper aims to draw attention to this issue. It presents basic outputs of a pilot study on pedestrian safety, with a focus on the use of mobile devices and headphones at selected non-signalized pedestrian crossings in three Slovak cities. Overall, 9% of pedestrians used headphones or mobile devices at observed pedestrian crossings (4% of them used headphones, 1% used headphones and at same time used their mobile phone, 2% made phone calls and 2% used their mobile phones). While these numbers can be considered relatively low, the study proved that during weekdays every 2 min someone was using the crossing without fully focusing on crossing the road safely. Another main finding was that although the safety risk at pedestrian crossings is increased by factors such as rush hour traffic or reduced visibility, pedestrian behavior related to the use of mobile phones and headphones does not change. A safety assessment was also carried out at the crossings. The results show that pedestrian behavior is not affected by the level of safety of the crossing (e.g., visibility of the crossing for drivers). The results of the presented analysis suggest that action is needed to change that. Due to the lack of information about accidents involving pedestrians using mobile phones and headsets when crossing the road, no relevant statistical data could be analyzed. The dataset collected can be used as a basis for further investigation or comparisons with other countries of the relevant indicators. In future work, we would like to include a pedestrian–driver interaction factor focusing on driver speed behavior in relation to pedestrians (who are on or are about to step onto a pedestrian crossing) and identify critical situations caused by improper behavior of drivers and/or pedestrians. This will help to understand speed adjustment problems related to pedestrian crossings.

Definition Of

Increases in mobile phone ownership and Internet access throughout Africa continue to motivate initiatives to use information and communication technologies (ICTs)—in particular, mobile phones—to address long-standing socioeconomic problems in the “developing world.” While it is generally recognized that mobile phones may help to address these problems by providing pertinent information, less widely known is exactly how (and if) a handset’s human–computer interface—that is, its software and hardware design—supports this form of communication. The concept of “affordances” has long been used to answer such questions. In this paper, we use Hartson’s definition of affordances to qualitatively investigate rural Kenyan women’s interactions with their mobile phones. Our detailed analysis provides empirically grounded answers to questions about the cognitive, physical, and sensory affordances of handsets used in our field sites and how they support and/or constrain mobile communication. We then discuss the implications of our findings: in particular, how this affordance-based approach draws attention to mobile phones’ design features and to the context in which they and their users are embedded—a focus which suggests new design and research opportunities in mobile communication.

The Relationship

This chapter illustrates the role of the mobile phone in the rise of new cultural models of parenting. According to a phenomenological theoretical approach to culture and everyday life, the author argues that the relationship between technologies, culture, and society should be conceived as a mutual construction. As cultural artefacts, mobile communication technologies both are domesticated by people into their cultural ways of living and create new ones. How are mobile phones domesticated by already existing cultural models of parenting? How does the introduction of the mobile phone affect family life and intergenerational relationships? How does mobile contact contribute in the construction of new cultural models of “being a parent” and “being a child”? Analysing new social phenomena such as “hyperparenting” and the “dialogic use” of mobile phones, the author argues upon the role of mobile communication technologies in articulating the paradoxical nature of the contemporary cultural model of family education.

Mobile Phone Usage

Ever since the discovery of the Mandelbrot set, the use of computers to visualise fractal images have been an essential component. We are looking at the dawn of a new age, the age of ubiquitous computing. With many countries having near 100% mobile phone usage, there is clearly a potentially huge computation resource becoming available. In the past years there have been a few applications developed to generate fractal images on mobile phones. This chapter discusses three possible methodologies whereby such images can be visualised on mobile devices. These methods include: the generation of an image on a phone, the use of a server to generate the image and finally the use of a network of phones to distribute the processing task.

In this article, we explore the day-to-day importance of digital media, specifically the use of mobile phones in the lives of migrant minors—also known as unaccompanied foreign minors—in juvenile residential centres. For this study, we employed a general ethnographic methodology and, in particular, a workshop based on different artistic techniques that encouraged the young people involved to become active participants, committed from the start in the generation of the material to be used for the analysis of their daily practices. This approach emerged from the recognition of the importance for these young people to feel included and connected. Migrant adolescents take refuge in their mobile devices to participate in the youth microculture, both locally and globally. In addition, they are able to access different social networks that allow them to play out the personas they wish to adopt. Finally, we recognise the importance of digital media in allowing them to maintain close and affective relationships with their relatives, fellow citizens, and communities in their country of origin.

AbstractRecent studies have shown what indispensable role mobile phones play as means of mobilization in contentious politics around the world. Nevertheless, there has been no clear elaboration of how mobile phone uses translate into mobilization in contentious politics. To fill this gap, the current study employs Passy’s (2003) framework of the threefold function of social ties as channels of mobilization to examine how mobile communication, embedding the dynamics of social ties, influences protest mobilization. It investigates two cases in rural and urban China in which Chinese people employed their mobile phones to mobilize participants for protests, and conducts 24 in-depth interviews with participants in these protests. Findings suggest that using mobile phones for mobilization registers the relational dynamics of social ties, which shapes participants’ perceptions of given protest issues, ensures the safety of protest recruitment and mobilization in a repressive context, and generates pressure on participation, all of which contributes to the mechanism of mobilization. This study concludes with the concept of ‘relational mobilization’, which addresses the embedment and relevance of social ties in the process of mobile-phone-mediated mobilization and its implication for Asian countries.
