There is an unprecedented growth of internet and internet-based technologies in the recent times. We are now switching to 5G as the most recent wireless communication technology. The internet of things has become a blessing for Industry 4.0 by challenging all the existing technologies in its utility for contributing to the industrial growth. There are a lot of wireless communication technologies for IoT, and it becomes difficult choice to select one suitable for an application. Authors have presented multi-criteria decision-making techniques which are very instrumental in making a confirmed decision on the choice of appropriate technology. This choice is done based on a number of deciding parameter which are used to differentiate between all the available options. The authors have identified 11 wireless communication technologies and seven parameters to evaluate the performance of the WCT's. All the seven parameters are considered in ranking and rank matrix is obtained. This technique can be very helpful for application designers so as to choose the right platform for their applications.

Background: The smart grid communication network is constructed with three tiers namely, Home Area Networks (HANs), Neighborhood Area Networks (NANs) and Wide Area Networks (WANs). These networks function with various communication protocols like table protocol, on-demand protocol, Wi-Fi, Zigbee, Z-Wave, Wi-MAX, GSM, LTE, Cognitive Radio Networks. The network interconnection is heterogonous and all appliances have to communicate through the IP gateways. A large amount of data is collected from various sensors placed in different locations. The analytics on large data- “big data” is essential because these data were used to organize and plan an efficient control and management of the smart home including secured data exchange in different sectors. Objective: This paper investigates broadly on data rate, channel bandwidth, power consumption, and a coverage range of both wired and wireless communication technologies used in residential buildings. Besides, a literature survey on optimization algorithms with various constraints to manage home appliances through scheduling is included. The paper also discusses the communication standards along with security and privacy requirements for smart metering networks. Conclusion: Discussion on IEEE standards for both wired and wireless communication protocols. Gives direction to identify the suitable communication technique through mathematical model for computing the communication channel bandwidth. Comparison of various optimization algorithms with multiple constraints in HEMS to achieve the minimum electricity cost and user comfort (with and without Renewable Energy Sources). From the investigation on both wired and wireless networks, the wireless communication networks (Zig-Bee & Wi-Fi) are mostly preferred to use in HAN because of more reliability and low cost. Zigbee is the most appropriate technology used for data transmission between the individual appliances and smart meters. Wi-Fi is a suitable technology for controlling and monitoring appliances because of its high data rate.

Artificial intelligence is already here in all facets of work life. Its integration into human resources is a necessary process which has far-reaching benefits. It may have its challenges, but to survive in the current Industry 4.0 environment and prepare for the future Industry 5.0, organisations must penetrate AI into their HR systems. AI can benefit all the functions of HR, starting right from talent acquisition to onboarding and till off-boarding. The importance further increases, keeping in mind the needs and career aspirations of Generation Y and Z entering the workforce. Though employees have apprehensions of privacy and loss of jobs if implemented effectively, AI is the present and future. AI will not make people lose jobs; instead, it would require the HR people to upgrade their skills and spend their time in more strategic roles. In the end, it is the HR who will make the final decisions from the information that they get from the AI tools. A proper mix of human decision-making skills and AI would give organisations the right direction to move forward.

As we enter the electronic age, technologies enabling e-learning have increased flexibility of learning location. Wireless communication technologies further increase the options for learning location (Johnson & Maltz, 1996; Wu, Huang & Chao, 2004). Advances in wireless communication technologies have recently provided the opportunity for educators to create new educational models. With the aid of wireless communication technology, educational practice can be embedded into mobile life without wired-based communication. With the trend of the educational media becoming more mobilized, portable and individualized, the learning form is being modified spectacularly. The mobile learning environment possesses many unique characteristics (Chen, Kao & Sheu, 2003).

PurposeThe digital transformation towards Industry 4.0 (I4.0) has become imperative for manufacturers, as it makes them more flexible, agile and responsive to customers. This study aims to identify the factors influencing the manufacturing firms’ decision to adopt I4.0 and develop a triadic conceptual model that explains this phenomenon.Design/methodology/approachThis study used a qualitative exploratory study design based on multiple case studies (n = 15) from the manufacturing industry in Malaysia by conducting face-to-face interviews. The data were analysed using NVivo. The conceptual model was developed based on grounded theory and deductive thematic analysis.FindingsResults demonstrate that driving, facilitating and impeding factors play influential roles in a firms’ decision-making to adopt I4.0. The major driving factors identified are expected benefits, market opportunities, labour problem, customer requirements, competition and quality image. Furthermore, resources, skills and support are identified as facilitating factors and getting the right people, lack of funding, lack of knowledge, technical challenges, training the operators and changing the mindset of operators to accept new digital technologies are identified as impeding factors.Research limitations/implicationsDue to its qualitative design and limited sample size, the findings of this study need to be supplemented by quantitative studies for enhanced generalizability of the proposed model.Practical implicationsKnowledge of the I4.0 decision factors identified would help manufacturers in their decision to invest in I4.0, as they can be applied to balancing advantages and disadvantages, understanding benefits, identifying required skills and support and which challenges to expect. For policymakers, our findings identify important aspects of the ecosystem in need of improvement and how manufacturers can be motivated to adopt I4.0.Originality/valueThis study lays the theoretical groundwork for an alternative approach for conceptualizing I4.0 adoption beyond UTAUT (Unified Theory of Acceptance and Use of Technology). Integrating positive and negative factors enriches the understanding of decision-making factors for I4.0 adoption.

The Industry 4.0 era has resulted in several opportunities and challenges for the manufacturing industry and for small and medium-sized enterprises (SME); technologies such as the Internet of Things (IoT), Virtual Reality (VR) or Cloud Computing are changing business structures in profound ways. A literature review shows that most large-sized enterprises have rolled out investment plans, some of which are reviewed during this research and show that Industry 4.0 investments in such companies exceed the turnover of SMEs in all cases (<€50 million), which makes access to those technologies by SMEs very difficult. The research has also identified two gaps: firstly, the recent literature review fails to address the implementation of Industry 4.0 technologies in SMEs from a practical viewpoint; secondly, the few existing roadmaps for the implementation of Industry 4.0 lack a focus on SMEs. Furthermore, SMEs do not have the resources to select suitable technologies or create the right strategy, and they do not have the means to be fully supported by consultancies. To this end, a simple six-step roadmap is proposed that includes real implementations of Industry 4.0 in SMEs. Our results show that implementing Industry 4.0 solutions following the proposed roadmap helps SMEs to select appropriate technologies. In addition, the practical examples shown across this work demonstrate that SMEs can access several Industry 4.0 technologies with low-cost investments.

Given the importance of new technologies in the classroom, especially in today’s information and communication societies, and following European Union recommendations to promote media literacy, this article reflects the need to educate not only in technical and efficient applications of communication technologies but also in their civic and responsible use, thus promoting participatory and deliberative processes which are the lifeline of a functioning democracy. The Greek dream of «isegoria», everyone’s right to speak, can become a reality in a digital culture, yet the highly selective use of communication technology can have the opposite effect: new forms of socialization can contribute to the expansion of «echo chambers» or «digital niches», shrinking communication spaces in which the right to speak dissociates itself from the responsibility to listen critically to what arises from a more open, plural and public sphere. One of the goals of education in a digital culture is precisely to diminish this trend that authors such as Sunstein, Wolton and Cortina have detected in recent years. This article proposes educational guidelines to avoid this bias by using communication technology to promote digital citizenship and the ethical values sustained by democratic societies.Asumiendo la importancia de las nuevas tecnologías en las aulas, especialmente en las actuales sociedades de la información y la comunicación, y siguiendo las recomendaciones de la Unión Europea a favor de la alfabetización mediática, el presente trabajo reflexiona acerca de la necesidad de educar no solo en los usos técnicos y eficientes de las tecnologías comunicativas, sino también en el uso responsable y cívico de las mismas, favoreciendo así los procesos participativos y deliberativos que son el sustento de una democracia viva. El sueño griego de la «isegoría», del igual derecho de todos al uso de la palabra, puede hacerse realidad en la cultura digital, si bien es cierto que un uso hiperselectivo de la tecnología comunicativa puede producir un efecto contrario: las nuevas formas de socialización pueden contribuir a la expansión de «cámaras de eco» o «nichos digitales», es decir, espacios discursivos cada vez más reducidos en donde el derecho a decir se desvincula de la responsabilidad de escuchar críticamente lo que procede de un espacio público más abierto y plural. Una de las metas de la educación en la cultura digital es precisamente frenar esta tendencia, detectada en los últimos años por autores como Sunstein, Wolton o Cortina. En el presente artículo se proponen orientaciones educativas para evitar estos sesgos y para fomentar, mediante la tecnología comunicativa, la ciudadanía digital y los valores éticos propios de sociedades democráticas.
