Dynamique concurrentielle : la retenue mutuelle entre concurrents monopoints sur un marché récemment libéralisé

This paper investigates mutual forbearance as a rivalrous mode in a sector with single-market competitors. For this purpose, we use multidimensional strategic sequences as a theoretical lens to analyze the evolution of competitive interactions in the Algerian mobile telecommunications sector following the introduction of third-generation wireless mobile telecommunications technology (3G), an event expected to stimulate competition. The findings show a de-escalation of competitive aggressiveness after the 3G introduction and reveal the existence of mutual forbearance among single-market competitors. This paper discusses the factors and mechanisms of mutual forbearance in sectors with single-market competitors.

The Role of 5G and IoT in Smart Cities

Smart cities, one of the key application areas of 5G and IoT technologies, have at their core the goal of improving quality of life, creating collaborative solutions, and addressing resource constraints. Examples of some of the many services integrated into the network of a typical smart city are related to smart health, smart transportation, smart buildings, smart hotels, smart industry, smart universities, etc. The new era of wireless mobile telecommunication technology and the IoT ecosystem is driving the opportunities for smart cities to not only solve existing problems but also create new services and functionalities that are out of the box and invisible to the end user. The main objective of this paper is to explore the role of 5G and IoT in smart cities. The market environment, key business developments, and trends related to the key smart cities’ enablers, IoT and 5G, are presented. An in-depth literature review followed by a discussion is substantiated with synthesised research findings on the current development, 5G coverage, use and deployment of IoT in smart cities, and forecasting the evolution of its application in smart cities.

Design of A Dual-Band Microstrip Antenna for 5G Communication

The necessity for mobile communication devices is increased rapidly. Users expect to get very fast information access and data access without delay. The fifth-generation (5G) development in wireless mobile telecommunication technology promises capacity enhancement, ease connectivity, high efficiency, and high data rate transmission. The appropriate device should support this improvement of the technology. The antenna is one of the main devices to support the high data rate transmission. This paper proposed designing a dual-band rectangular patch antenna in 29 GHz and 38 GHz that supports 5G technology. This microstrip antenna is composed of 4 patch array elements to obtain higher gain. The material used for this microstrip antenna is RT Duroid 5880 with a dielectric constant of 2.2 and a thickness of 1.575 mm. Both measurement and simulation are confirmed that the 2×2 array microstrip antenna in 29 GHz and 38 GHz frequency have a return loss value of -12.5 dB and -16 dB, respectively. The bandwidth for both frequencies has a value of 4.5 GHz and 3.75 GHz.

Performance Analysis of WOFDM‐WiMAX Integrating Diverse Wavelets for 5G Applications

In the 5th generation (5G) and 6th generation (6G) of wireless mobile telecommunication networks, the requests for an elevated data rate with access to stationary as well as portable customers are going to be overwhelming. Mobile worldwide interoperability for microwave access (WiMAX) comes out as a favourable alternative that is intelligibly developed and more matured than wireless fidelity (Wi‐Fi). Mobile WiMAX makes use of the orthogonal frequency division multiple access (OFDMA) technology for its two‐way communication to enhance the system performance in fading environments making it more suitable for 5G applications. The diverse OFDM forms deliberated here are the fast Fourier transform‐ (FFT‐) based WiMAX and discrete wavelet transform‐ (DWT‐) based WiMAX. The suggested study exhibits the bit error rate (BER) and peak to average power ratio (PAPR) reduction by integrating different wavelet families, i.e., Haar, symlet, coiflet, and reverse biorthogonal over Rayleigh fading channel. The simulation results obtained by MATLAB depicts an improvement in PAPR reduction, and signal to noise ratio (SNR) requirement is also reduced by 6‐12 dB by using DWT‐incorporated WiMAX at a BER of 10-4.

Social media – on the edge between personal and professional development

Introduction. Social media steadily and constantly envelops all aspects of peoples' lives. Thus it is of crucial importance to investigate and measure social media activities' impact on their inclusion in the formation of today’s and future societies as more and more online activities have been incorporated in real life personal and professional activities.
 Aim and tasks. This article explores the new trends in people’s activities at the workplace and outlines the main concerns regarding keeping the line between personal and professional online activities.
 Results. Social media are now an integral part of the everyday life of modern man. Since a person spends most of their day at work or in pursuit of their profession, they also seek to engage in personal activities within the working day (talking on the phone with family or friends, shopping online, reading news etc.).
 A user is created with features specific to the internet generation. This new type of user has specific features that allow researchers to talk about the emergence of a next-generation user. The Next Generation User is a person who has access to the Internet from multiple locations and devices.The rapid penetration of social media in people's everyday life implies a greater impact on all users' real-life and online activities. Evidence of the latter can be found in very common situations when users upload photos or videos from parties or events in real time not always tacking into consideration the possible outcomes for their personal and professional lives.
 Conclusions. Managers consider that workers should focus more not only on the technical limitation of the exchange in of information on social media but also on a better personal judgment about the nature and volume of the shared information. The intensity of social media activities of the workers is monitored actively by employers and coworkers alike and can be seen as an indicator of low efficiency or irresponsible personality. With the fast development of wireless mobile telecommunications technology and the growing multitude of mobile apps online activities become a real threat for workers’ productivity and the development of workplace culture.

Merging anomalous data usage in wireless mobile telecommunications: Business analytics with a strategy-focused data-driven approach for sustainability

Mobile internet usage has exploded with the mass popularity of smartphones that offer more convenient and efficient ways of doing anything from watching movies, playing games, and streaming music. Understanding the patterns of data usage is thus essential for strategy-focused data-driven business analytics. However, data usage has several unique stylized facts (such as high dimensionality, heteroscedasticity, and sparsity) due to a great variety of user behaviour. To manage these facts, we propose a novel density-based subspace clustering approach (i.e., a three-stage iterative optimization procedure) for intelligent segmentation of consumer data usage/demand. We discuss the characteristics of the proposed method and illustrate its performance in both simulation with synthetic data and business analytics with real data. In a field experiment of wireless mobile telecommunications for data-driven strategic design and managerial implementation, we show that our method is adequate for business analytics and plausible for sustainability in search of business value.

Measuring the World

The authors claim that location information of stationary ICT components can never be unclassified. They describe how swarm-mapping (crowd sourcing) is used by Apple and Google to worldwide harvest geo-location information on wireless access points and mobile telecommunication systems' base stations to build up gigantic databases with very exclusive access rights. After having highlighted the known technical facts, in the speculative part of this article, the authors argue how this may impact cyber deterrence strategies of states and alliances understanding the cyberspace as another domain of geostrategic relevance. The states and alliances spectrum of activities due to the potential existence of such databases may range from geopolitical negotiations by institutions understanding international affairs as their core business, mitigation approaches at a technical level, over means of cyber deterrence-by-retaliation.

Dronesourcing: a modular, expandable multi-sensor UAV platform for combined, real-time environmental monitoring

ABSTRACTThe systematic environmental monitoring of the land, atmosphere, oceans and their coupling zones, is assisted by the use of unmanned aerial vehicles (UAVs) that can operate over rural and/or urban areas to provide enhanced spatial and temporal measurement resolutions compared against corresponding satellite products. The international UAV market includes a vast number of solutions that carry sensors for environmental monitoring varying in type, flight time, carrying weight, communication, and autonomous flight. The majority of these commercial UAVs (especially the low-cost ones) have been designed for specific applications and their main disadvantage is that they can only integrate the payload they have been initially designed to carry, thus presenting minimal modularity. This work presents a modular and affordable platform where the user can easily adapt almost any type of environmental monitoring sensor, which can transmit its measurements to the UAV flight controller without the need for any additional modification. A novel communication protocol has been developed that is also capable to incorporate proximity sensors for collision avoidance. In addition, a wireless mobile telecommunications module incorporation through the use of mobile devices on the UAV provides real-time animated map generation along with cooperative capabilities for fleet missions.

Degradation mode and criticality analysis based on product usage data

Over the last decade, a rapid development of internet, wireless mobile telecommunication, and product identification technologies make whole product life cycle visible and controllable, which can improve several operational issues over the whole product life cycle: product design improvement, predictive maintenance, rational decision on end-of-life products, and so on. The key element to solve these issues is to assess the degradation status of a product based on gathered data during product usage period. However, despite its importance, due to the interrupted information flow of the product life cycle after product sales, it has not received enough attention in the literature until now. To overcome this limitation, this study develops a decision support method, called degradation mode and criticality analysis (DMCA), for the analysis of product degradation status based on gathered product usage data. The proposed method enables us to identify and assess the degradation status of a product and give a suitable guide for the next action. To show the effectiveness of the proposed approach, a case study for a heavy construction equipment vehicle is introduced.

One-to-One Embedding between Honeycomb Mesh and Petersen-Torus Networks

As wireless mobile telecommunication bases organize their structure using a honeycomb-mesh algorithm, there are many studies about parallel processing algorithms like the honeycomb mesh in Wireless Sensor Networks. This paper aims to study the Peterson-Torus graph algorithm in regard to the continuity with honeycomb-mesh algorithm in order to apply the algorithm to sensor networks. Once a new interconnection network is designed, parallel algorithms are developed with huge research costs to use such networks. If the old network is embedded in a newly designed network, a developed algorithm in the old network is reusable in a newly designed network. Petersen-Torus has been designed recently, and the honeycomb mesh has already been designed as a well-known interconnection network. In this paper, we propose a one-to-one embedding algorithm for the honeycomb mesh (HMn) in the Petersen-Torus PT(n,n), and prove that dilation of the algorithm is 5, congestion is 2, and expansion is 5/3. The proposed one-to-one embedding is applied so that processor throughput can be minimized when the honeycomb mesh algorithm runs in the Petersen-Torus.

A framework for RFID applications in product lifecycle management

This study introduces an overall framework for radio frequency identification (RFID) applications in product lifecycle management (PLM). Recently, with emerging technologies related to product identification and wireless mobile tele-communication, PLM provides a new environment that enables lifecycle actors to gather and analyse product lifecycle information, and make efficient decisions without spatial and temporal constraints. However, previous research has paid little attention to how to apply the emerging technologies into PLM. To cope with this limitation, in the current study, RFID applications in PLM are dealt with from technical and business viewpoints. To this end, an overall framework for RFID applications in PLM is proposed. It contains the definition of a product embedded information device (PEID) that uses RFID technology, its specification and operation scenarios for each application. Furthermore, application issues and their overall procedures are introduced for each lifecycle phase.

Product Life-Cycle Metadata Modeling and Its Application with RDF

The whole product life cycle consists of three phases: beginning of life (BOL), middle of life (MOL), and end of life (EOL). Although large amounts of product life-cycle data are generated over the whole product life cycle, data flows are rather vague after BOL. Over the last decade, however, emerging Internet, wireless mobile telecommunications, and product identification technologies have created the potential of making the whole product life cycle visible. As a result, the scope of data to be managed has expanded over the whole product life cycle. Hence, it becomes important to describe product life-cycle metadata in a systematic manner. Although much attention has been paid to data modeling over several objects such as products and processes, modeling methodology for product life-cycle metadata is not well developed. To cope with this limitation, we develop a modeling method for product life-cycle metadata by using the resource description framework (RDF). We define an RDF data model and its schema for describing and managing product life-cycle metadata. In addition, we describe how the proposed RDF model can be usefully applied to track, trace, and infer product life-cycle data with an RDF query language.

Radio frequency exposure and safety associated with base stations used for personal wireless telecommunication

The persistent public concern about the biological effects and safety of RF exposure from wireless base stations can be traced, in part, to the public's desire to protect itself from unnecessary exposure to potentially harmful radiation, including RF and microwaves associated with cellular mobile telecommunication operations. This concern is posing new questions regarding the adequacy of the existing knowledge of biological effects of RF electromagnetic fields, and of the protection afforded the public from the harmful effects of these fields. Existing guidelines and standards were developed primarily from a scientific database derived using continuous-wave (CW) exposures. While some studies have reported biological effects specific to the signal forms and modulations commonly used by wireless mobile telecommunication, a majority of previous studies using these signal forms and modulations did not show any effect. However, given the confined scope and extent of recent studies, a wider range of investigations would be propitious in elucidating the safety of wireless base stations.

WmATM enhanced software definable radio system

Driven by the markets and subscribers, broadband telecommunication services are getting more and more significant throughout the world. ATM and Internet technologies are taking the leadership in this storm to bring up the new era of information society. Wireless mobile communication is a very potential system in view of its low cost as well as flexible coverage. Constructing a new broadband, high-speed wireless mobile telecommunications, with full compatibility to existing wireless standards will become an emerging demand in the following years. This kind of system can provide real-time multimedia communications, including voice, data and video to each mobile user or host, and support free roaming and handover any time, anywhere and for anyone. Hence, an intelligent broadband software definable base station is proposed to reflect the advancement of the next generation wireless mobile communications. wmATM (wireless mobile ATM) based software radio will greatly contribute to this technology and enhance the system's performance.
