Ever since the introduction of fifth generation (5G) mobile communications, the mobile telecommunications industry has been debating whether 5G is an “evolution” or “revolution” from the previous legacy mobile networks, but now that 5G has been commercially available for the past few years, the research direction has recently shifted towards the upcoming generation of mobile communication system, known as the sixth generation (6G), which is expected to drastically provide significant and evolutionary, if not revolutionary, improvements in mobile networks. The promise of extremely high data rates (in terabits), artificial intelligence (AI), ultra-low latency, near-zero/low energy, and immense connected devices is expected to enhance the connectivity, sustainability, and trustworthiness and provide some new services, such as truly immersive “extended reality” (XR), high-fidelity mobile hologram, and a new generation of entertainment. Sixth generation and its vision are still under research and open for developers and researchers to establish and develop their directions to realize future 6G technology, which is expected to be ready as early as 2028. This paper reviews 6G mobile technology, including its vision, requirements, enabling technologies, and challenges. Meanwhile, a total of 11 communication technologies, including terahertz (THz) communication, visible light communication (VLC), multiple access, coding, cell-free massive multiple-input multiple-output (CF-mMIMO) zero-energy interface, intelligent reflecting surface (IRS), and infusion of AI/machine learning (ML) in wireless transmission techniques, are presented. Moreover, this paper compares 5G and 6G in terms of services, key technologies, and enabling communications techniques. Finally, it discusses the crucial future directions and technology developments in 6G.

The need for high-quality communications networks is urgent in data-based farming. A particular challenge is how to achieve reliable, cost-efficient, secure, and broadband last-mile data transfer to enable agricultural machine control. The trialed ad hoc private communications networks built and interconnected with different alternative wireless technologies, including 4G, 5G, satellite and tactical networks, provide interesting practical solutions for connectivity. A remotely controlled tractor is exemplified as a use case of machine control in the demonstrated private communication network. This paper describes the results of a comparative technology analysis and a field trial in a realistic environment. The study includes the practical implementation of video monitoring and the optimization of the control channel for remote-controlled unmanned agricultural tractors. The findings from this study verify and consolidate the requirements for network technologies and for cybersecurity enablers. They highlight insights into the suitability of different wireless technologies for smart farming and tractor scenarios and identify potential paths for future research.

Interrogating the terminology of “mobile” communication, this article notes that media and communicative practices have been mobile for millennia. What’s mobile about cell phones and other current mobile media is a new range of contexts in which personally meaningful and socially consequential interactions become possible. Mobile media should be studied, above all, as resources of social action across physical space. Mobile media, further, provide the wider field of research with an opportunity to revisit the great divide between technologically mediated and embodied communication. Technologically mediated communication remains grounded in human bodies residing in local places. Humans can be understood as a first degree of media whose communicative and performative reach has been extended in time and space by historically shifting technologies.

In this introduction, we argue for an expanded focus in mobile media and communication studies (MMCS) that accounts for the many types of mobile media that affect our lives. We begin by pointing out that mobile phone/smartphone research has dominated MMCS as a field. That focus makes sense, but it runs the risk of MMCS essentially turning into “smartphone studies,” which we argue would limit our impact. To make that case, we identify a few examples of the types of oft-ignored technologies that could add to the depth and breadth of MMCS research (e.g., RFID [radio frequency identification] tags, the Walkman, barcodes). We then summarize the articles in this special issue to categorize the breadth of this research, which ranges from analyses of mobile fans to autonomous cars to mobile infrastructure.

By examining contemporary changes in the mechanisms and practices of representation and communication, this paper focuses on the copy-and-paste affordance fostered by mobile technologies and digital technologies at large. Its widespread use is affecting radically (1) the acceptability standards of (in)coherent patterns of text production, and (2) the criteria defining successful communication, which coherent cooperation to a mutual understanding is sometimes less relevant than the transformation and reinterpretation of texts according to the sign-maker’s interests in participating to multiple communicative networks. In this light, by pinpointing the abilities required and developed in the use of mobile technologies, the paper hypothesizes possible paths for teaching in such a changed semiotic landscape.

With the popularization of smartphones, location-based services are increasingly part of everyday life. People use their cell phones to find nearby restaurants and friends in the vicinity, and track their children. Although location-based services have received sparse attention from mobile communication scholars to date, the ability to locate people and things with one’s cell phone is not new. Since the removal of GPS signal degradation in 2000, artists and researchers have been exploring how location-awareness influences mobility, spatiality, and sociability. Besides exploring the historical antecedents of today’s location-based services, this article focuses on the main social issues that emerge when location-aware technologies leave the strict domain of art and research and become part of everyday life: locational privacy, sociability, and spatiality. Finally, this article addresses two main topics that future mobile communication research that focuses on location-awareness should take into consideration: a shift in the meaning of location, and the adoption and appropriation of location-aware technologies in the global south.

Studies have shown that ethnic segregation is conducive to social segregation. With the advent of information and communication technologies, mobile communication can support non-local social interactions and reconfigure the network composition of ethnic groups. This study focused on the similarities and differences between ethno-national groups in the structure of their cell phone communications. Data for this study include a sample of 9,099 business customers’ mobile phone calls from an Israeli mobile operator and tested two theoretical explanations. The social stratification approach predicts that mobile communication will reflect the patterns of spatial and social stratification that exist in society. On the other hand, the social diversification hypothesis expects that residentially and socially segregated minority groups will take advantage of mobile communication to diversify their social contacts and to engage in mobile communications with non-local and out-group ties. The findings suggest that in the information society, both structural conditions (the stratification approach) and social incentives (the diversification approach) are relevant for the understanding of inter-ethnic mobile communication, and structural conditions reduced inter-group mobile communication patterns. The Arab Israeli minority was more likely than the Jewish Israeli majority to engage in mobile communication with non-local ties and out-group members. Yet, structural conditions reduced inter-group mobile communication patterns. The theoretical implications of the findings for inter-group mobile communication are discussed.

Communication, Technology, and Society have an effective role in building globalization. Marketing communications, emerging technologies, and intelligent societies present in globalization are making many impacts on the life of the world. Digital technology is able to make it easy for people to find information, find groups and provide responses widely and freely. A digital app on mobile called DisCas tries to differentiate it from other social pedia digital technologies. DisCas a start is growing for a noble cause. Starting from unrest in society when a problem arises, many opinions and misinformation are scattered and do not solve the problem. DisCas is here to fulfill an application called Social Pedia, a responsible opinion and provide appreciation in the form of buying and selling opinions, ideas, captions, images, photos, and videos. The research method uses interview techniques with CEH DisCas interviewees. The results of the discussion of marketing communications presented by DisCas rely on digital marketing, advertising in print and digital media, creative content through endorsers, and even asking me anything or AMA in a conversation about blockchain. The conclusion of this article states that Social Pedia has a good future and extraordinary achievement of social pedia that is packaged responsibly and easily benefits through image ideas, opinions, and works easily accessible to all levels of society in the world using mobile application technology.

Mobile technologies are all-pervasive in the current digital generation, and college students rely on their mobile phones to communicate on a daily basis. In the midst of the myriad of applications available to download on the mobile, some tools have become more well-known and more often adopted than others. An example of such a tool is WhatsApp, which gains an increasing, widespread number of users on a daily basis, particularly in the Middle East region. The present study investigated college students' use of WhatsApp as a communication tool, and used Lebanon as a case study. A qualitative research design was implemented to understand the perceptions of college students vis-à-vis WhatsApp, and to investigate the motivational factors behind the popularity of this communication tool. The results revealed four themes: simplicity for discussion and coordination, cost-effectiveness, immediacy and sense of belonging.

In a very short period of time, mobile telephony, tablets, and other hand-held devices swept the world. The world’s first cellular network was created in 1977, but the mobile phone has made history as one of the fastest diffusing communication technologies, reaching nearly six billion subscribers by 2011. The time is right to define mobile media in an effort to better understand mobile communication technologies and their broad implications for the fundamental meanings of media, communication, community, social institutions, and especially society. In this article, I argue that the advent of mobile telephony as a wireless telecommunication system and portable platform for human communication has seemingly transformed the classical definition of mass communication. In fact, mobile media-supported communication, such as mobile news and mobile tweets, has accelerated what communication scholars have described as “the end of mass communication.” The article ends with a call for a holistic view of mobile communication research.

With the growing popularity of mobile technologies and the increasing use of groups within organizations, it is important to understand the collaboration contexts where mobile collaboration technologies (MCTs) are essential. This is especially critical given the high cost associated with the acquisition and implementation of MCTs and the need to make an informed decision regarding the appropriateness of MCTs. In this paper, the authors address this issue by first drawing on real life-based collaboration scenarios and examining the technology requirements of groups; second, comparing the features offered by MCTs with those of FTF and two types of CMCTs; third, proposing a collaboration environment-technology fit perspective in realizing optimal usage of a collaboration technology; and fourth, creating the Group Collaboration Technology Repertoire Grid, which maps the “ideal” collaboration technology(s) repertoire for each type of collaboration environment. The grid highlights the collaboration environments that would need MCTs and provides managers or organizational group leaders the ability to map their collaboration environments into a specific category and thus more easily decide on the particular collaboration technology repertoire that would be most beneficial.

Direct inter-vehicular communication means that there is no infrastructure. This is in sharp contrast to mobile communication within a cellular network or between a moving vehicle and the roadside. It is assumed in this article that the mobile channel between the two vehicles is too rapidly time variable to be possible to measure it in real-time. The natural choice is then to select those coding and modulation techniques for which the knowledge of the channel state is not necessary at both the transmitter and the receiver, that is, to consider only differential and noncoherent communications technologies. As interesting options, the celebrated Golden code and the recently developed Golden-Alamouti space-time trellis coding are also proposed for inter-vehicular communications.

<p>With the emergence of mobile technologies in education, the special needs students are gaining the infinite benefits that could enhance their learning sessions. Numerous studies are conducted on the usage of mobile technologies among the special needs students including their acceptance towards the technologies, its advantages as well as the obstacles on the utilisation of mobile technologies. However, fewer studies are done on the usage of mobile technologies among the hearing-impaired (HI) students. There is a need for more studies on that as the number of hearing-impaired people are increasing continuously around the globe. Hence, the aims of the study are to explore the hearing-impaired students’ perspectives on the usa of mobile technologies in learning ESL. In-depth interviews are conducted among the selected ten hearing-impaired students from four different secondary schools in Malaysia and the notable finding demonstrates the majority of them believed that mobile technologies assist them in learning. This study provides the insights for the education stakeholders, especially the policy makers and inventors to create the solutions and improvise the features of mobile technologies that are more user-friendly towards the hearing-impaired students.</p>

Purpose – The purpose of this paper is to describe the use of mobile technologies to develop new ways of Libraries and Information Centre. Mobile devices help to connect with patrons. Creating a library application (“app”) or mobile Web site that allows patrons to access library hours, view their library account or even search databases is easier than most people think. The resources below should help libraries begin to plan and implement their own unique mobile presence: analyzing the present usage of mobile devices; providing an overview of devices, providers and features; describing the various activities these devices support for well library use; focusing how libraries and our librarians are responding with services tailored for these devices; and what can be done by libraries in future in this respect”. Design/methodology/approach – Information and Communications Technology continues to expand the boundaries of higher education into the “anytime/anywhere” experiences. Mobile communication is transforming how people search, receive and interact with information on a daily basis. In just a few short years, smart phone ownership has skyrocketed, and popular use of e-readers has been steadily on the rise. These advanced mobile tools provide portable access to the world of information, across boundaries of subject, discipline and industry. Findings – Mobile technology holds great promise for enabling libraries to provide enhanced services in a form users increasingly are demanding. If this promise is to be fully realized, however, libraries will need to conduct analyses and make smart decisions to address the issues outlined above, support staff education and explore partnerships and new funding models, and be prepared to compromise with respect to their traditional information delivery models. Originality/value – The explosion of advanced mobile technology and robust digital information collection capabilities should prompt libraries to examine carefully the ramifications for user privacy. Libraries can maintain their commitment to user privacy without overcompensating by imposing burdensome security measures or annoying interruptions. For example, libraries do not have to show users a privacy statement or security warning every time they want to access information on a mobile device. A single log-in and acceptance of terms of use, similar to the procedures for other mobile applications and services, should suffice. At the same time, libraries can take the opportunity to educate users in best practices with respect to privacy issues associated with the use of mobile devices.

In thinking about convergent media and new digital technologies, the place of mobile services and technologies in the broader media policy field has not been addressed satisfactorily. This article reviews the beginnings of cellular mobiles in Australia to see what this piece of history can tell us about today's policy challenges. My case study revolves around the technology choices made by the federal government in the 1980s, especially the decision to essentially mandate the second-generation Global Standard for Mobiles (GSM) digital standard. I examine the structuring of the mobiles market with three initial licence-holders, and look at the implications of this as mobiles developed through the 1990s. The article offers a brief comparison with the New Zealand mobiles market, and also the promising yet ultimately ‘failed’ technology of the public-access cordless telephone. I conclude with some observations about how such critical examination of history can help to open up policy vistas about mobile media.

Nowadays, in the aeronautical environments, the use of mobile communication and other wireless technologies is restricted. More specifically, the Federal Communications Commission (FCC) and the Federal Aviation Administration (FAA) prohibit the use of cellular phones and other wireless devices on airborne aircraft because of potential interference with wireless networks on the ground, and with the aircraft's navigation and communication systems. Within this context, we propose in this paper a movement recognition algorithm that will switch off a module including a GSM (Global System for Mobile Communications) device or any other mobile cellular technology as soon as it senses movement and thereby will prevent any forbidden transmissions that could occur in a moving airplane. The algorithm is based solely on measurements of a low-cost accelerometer and is easy to implement with a high degree of reliability.

Media sport researchers are frequently neglecting to analyse the rise, effects, and meanings of mobile media and communications. This situation is partly explained by the fact mobile media encompass practices, technologies, and markets that are grounded historically in the telecommunications and information technology industries, which sit apart from the broadcast (radio and television) and print (newspapers and magazines) media that dominated the transmission, circulation, and representation of professional sport for over a century. It is now time to build a research agenda dedicated to the study of mobile media and communications, especially given the proliferation of mobile digital computing and mobile Internet. Three reasons are presented in support of this argument. First, mobile media and telecommunications introduce stories into the history of media sport that need to be recognised if its contemporary features are to be properly contextualised and understood. Second, these stories are linked to an expanded range of meanings, technologies, and infrastructures captured by the term media that must now be accounted for. Third, mobile media reveal accelerating forms of hyper-commodification that are locking media sport into privately controlled market frameworks. A mobile research agenda also offers the potential for media sport scholarship to make a sustained contribution to the study of mediatisation processes, as well as mobile media and communications studies.
