Study of Consumer Behaviour Towards Reliance Jio

The main objective of this project is to study the awareness of Reliance Jio amongst the customers compared to other telecom service providers. The satisfaction of customers is very important and with various products and services offered by the company its customers seem to be meaningless if it‟s not beneficiary to the customer from their end, so the second objective of this research is to study the customer satisfaction level of customers towards Reliance Jio and its services. To achieve success in long run a company needs a thorough study of its SWOT analysis (Strength, Weakness, Opportunities, and Threats). So the third objective of this research is to find the market potential and market penetration of Reliance Jio products and services. Reliance JioInfocomm Limited (Commonly called RJIL) is an Indian Internet access (commonly called „Broadband‟) and telecommunications company headquartered in Mumbai India‟s largest private sector company, is the first telecom operator to hold pan India Unified License. Reliance Jio is setting up a pan India telecom infrastructure to provide fourth generation LTE TDD high speed wireless internet and mobile communication services which was then launched in June 2015. Reliance Jio was founded in 2010 by MukeshAmbani. Reliance Jio offers mobile telephony and wireless broadband. Parent company of Reliance Jio is Reliance Industries and its subsidiary is LYF. To study the objectives discussed two types of sources were used to collect the data: - Primary and Secondary data. Primary data is also called as „First-hand data‟ or „Raw data‟. The primary data primarily means the unfiltered raw data collected by the researcher in the research process. In this project for the primary data a sample of 40 people were surveyed.

Peculiarities of the Operation оf Optical Communication in case of emergencies

Today, in connection with the beginning of the full-scale armed invasion of the RF on the territory of Ukraine, questions related to fire safety and stable electricity supply have arisen before our state. It. in turn, led to numerous problems in the communication system. Against this background, after damage to power supply lines and strategic objects, the search and deployment of power supplies independent of the usual supply sources became urgent. After all, under the conditions of emergency and planned power outages, only the presence of such means of power supply as fuel generators and batteries make it possible to provide work and training for a huge number of people. Thanks to the fact that people, without wasting time and wasting energy on unnecessary things and affairs, began to work on the issue that is associated with a sudden or planned power outage for known or not entirely known reasons, work for most people resumed. Autonomous power sources were fuel generators. Small shopping centers and shopping and entertainment centers have installed powerful diesel generators on their premises to power large premises. Some installed one diesel generator on each individual wing. This was done if the room was too large for one diesel generator. Small establishments, for example: cafes, restaurants, bars, pubs, hookah bars, small offices, offices, workshops, etc. installed gasoline generators if the premises were the size of a garage, a three-room apartment with an area of 92 m2 or the size of a small two-story country house with walls 8 meters long each and ceilings up to 2 meters high. Powerful diesel generators were installed in the premises, which were more than 100 m2 in area. Most generators had an automatic start feature. Some generators had an installed automatic start function, and some did not have this function, and therefore had to install this function separately. Telecommunications companies and mobile communication service companies and provider companies that sell and service cable Internet also did not waste time and effort and also installed generators on their territories. Provider companies and mobile communication service companies were the first to decide to install autonomous emergency power supplies in their territories. This was done on purpose, since the equipment that provided and monitored wireless and cable Internet services and mobile communications services was powered by network electricity, and during the absence of network electricity, the equipment obviously stopped working. Because of this, cable Internet and mobile communications were lost, which had a negative impact on some citizens of Ukraine. It had a negative impact on them, since some citizens, as mentioned above, could work or study remotely. Someone lost their job, someone lost their business due to power outages. Also in connection with this, huge accounting gaps appeared. The introduction and use of emergency power helps solve this problem.

ПРОГНОЗИРОВАНИЕ СТЕПЕНИ ПРОНИКНОВЕНИЯ СОТОВОЙ СВЯЗИ В РЕГИОНЫ РОССИЙСКОЙ ФЕДЕРАЦИИ НА ОСНОВЕ S-МОДЕЛЕЙ

The article examines the dynamics of the degree of penetration of cellular communications in the Russian Federation. In general, for Russia, federal districts, Moscow and St. Petersburg, based on official data from Rosstat, models were built that describe the time dependence of the number of active SIM cards per 1000 residents. It has been established that this dependence is best described by the Gompertz curve containing the asymptotic level of indicators. The reliability of the resulting models exceeds 97%. The revealed ratios indicate a significant difference in the provision of the population of federal districts with mobile communication services. The asymptotic level of the number of SIM cards per person for the Central Federal District is almost twice as high as for the North Caucasus. The results of the study confirm the presence of digital inequality in Russian regions, noted in works devoted to the analysis of the spread of information and communication technologies. Socio-economic differentiation, the large extent of the country, gaps in the level of education and digital literacy of the population are the causes of digital inequality. And this, in turn, leads to a decrease in economic efficiency. The existence of an asymptotic level and a slowdown in the growth rate do not give reason to assume that the gap in the provision of cellular communication services will be eliminated.

Progressive Collaborative Method for Protecting Users Privacy in Location-Based Services

The development of new mobile communication and information service technologies has opened up exciting possibilities for location-based services. Users of location-based services (LBS) can access vital data from their service providers by utilizing their location data. Maps and navigation, information services, tourist information services, social networking, and many more popular applications are available. A user's location and other personal details must be submitted to the providers of location-based services in order for them to work. For example, details about one's whereabouts and identity. By "location privacy," we mean the idea that third parties shouldn't be able to track a user's precise whereabouts. It is important that users' sensitive information be hidden from unauthorized individuals when communicating. Most difficult in LBS location-based are concerns about communications and data. Each peer does their duty reciprocally in a collaborative method, which is a completely distributed technique. For the most secure and private location-based services (LBS), it employs cryptographic methods. The number of people using LBS is growing at a rapid pace these days. At this time, there isn't a single method available that has scalability capabilities. Building a realistic and computationally efficient solution that offers high privacy while decreasing processing overhead and improving scalability is a challenging task. The suggested method is cost-effective, supports scaling, is highly resilient against security and privacy assaults, and ensures privacy.

부가가치세법상 매출에누리와 판매장려금에 관한 연구

[Purpose] This study analyzes the trend of recent precedents regarding sales allowance and sales incentives under the Value－Added Tax Act, which have become an issue in practice due to the ambiguous distinction, and distinguishes between sales allowance and sales incentives, focusing on the Supreme Court ruling 2017Du53170, pronounced on August 31, 2022.
 [Methodology] According to the tax law, various systems for sales allowance and sales incentives were summarized, and related prior studies were reviewed. In addition, by analyzing existing precedents, trends and related cases of recent precedents of sales allowance and sales incentives were comprehensively analyzed. Focusing on the Supreme Court's 2017Du53170 ruling, the legal basis for the distinction between sales allowance and sales incentives was presented.
 [Findings] According to the Supreme Court's 2017Du53170 ruling, subsidies paid to customers had an economic effect of reducing supply prices, but highlighted the formal aspects of the transaction, such as terms and conditions, and contracts, and judged that subsidies in this case did not correspond to the amount of money excluded from the supply price of mobile communication services because they were not directly related to the service provided. In other words, the amount of sales allowance was narrowly interpreted from a formal point of view. Direct deduction, one of the requirements for acknowledging the amount of the discount, must be judged based on whether the supply price has been substantially reduced.
 [Implications] This study is expected to contribute to increasing legal stability and predictability by once again checking and determining whether to exclude the amount from the supply price depending on the relevance of the transaction, in a situation where interpretation problems continue to arise due to ambiguous distinction criteria for sales allowance and sales incentives.

The evaluation of EMI characteristics of 4G-IMT system on FAST around its RQZ

Mobile communication base stations have become ubiquitous with the popularization and development of mobile communication services. Although the Chinese government has designated a radio quiet zone (RQZ) specifically for Five-hundred-meter Aperture Spherical radio Telescope (FAST), the 4G International Mobile Telecommunications (4G-IMT) system is still heavily used to meet the communication needs around the RQZ. To assess the Electromagnetic Interference (EMI) caused by 4G-IMT base stations on the performance of FAST, this paper employs the International Telecommunication Union (ITU) deterministic radio wave propagation prediction model. The interference of 4G-IMT base stations on FAST is evaluated based on relevant parameters, such as the frequency used by both FAST and the base station, in conjunction with the FAST threshold protection requirements. The results indicate that 47.73 % of the data exceed the radio astronomy protection threshold of FAST. In addition, a field experiment was conducted to verify the accuracy of the radio wave propagation prediction method used. The root-mean-square error between the predicted value and the measured value was found to be 6.94 dB, supporting the accuracy of the predicted results. The findings of this study can help suppress interference from mobile communication services around the RQZ of FAST and optimize the electromagnetic environment around FAST.

PRELIMINARY STUDY OF AMBIENT ELECTROMAGNETIC RADIATION AT BASE TOWER STATIONS IN RESIDENTIAL AREAS IN KUALA NERUS

Introduction: Mobile communications developed into an integral component of our daily life. The growing demand for mobile communication services in Kuala Nerus has seen an increase in the installation of base station towers (BST) in residential areas, as well as near schools, and hospitals. Kuala Nerus was selected as a study location because it is a newly developed district in Terengganu, hence, it is crucial to perform electromagnetic radiation (EMR) measurements in the early stages. Objective/aim: This study aimed to measure the RF EMR exposure level in residential areas in Kuala Nerus by measuring the strength of its electric field (EF) strength and power density (PD) value while comparing it with the ICNIRP’s standard guidelines. Materials and methods: Measurements were made using NARDA NBM 550, connected to a probe that could detect frequencies from 100kHz to 6GHz. The data collection period for each point was approximately 6 minutes during daytime. Results: Average radiation levels in terms of EF strength at all locations were found to vary between 0.26 (V/m) to 3.35 (V/m) (PD value about 0.02 µW/cm² to 2.97 µW/cm²). The highest level was measured at Surau Kg Pok Tuyu, which was 5.48% or 18 times lower than the MCMC exposure limit for public areas. Conclusion: The RF value obtained does not exceed the standard limit, which in turn contributes indirectly to health monitoring initiatives for public NIR exposure. This study found that exposure levels in selected BSTs in residential areas in Kuala Nerus were within the standard guideline limits.
 
 

Feature selection based machine learning models for 5G network slicing approximation

The development of 5G networks is expected to introduce novel concepts and challenges in domains such as technology, security, and customer demands due to advancements in mobile internet and communication services. The three main services that the 5G network provides are enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable low-latency communication (URLLC). Network slicing is the practice of dividing a single physical network into many virtual networks in order to facilitate the delivery of multiple services across that network. These slices improve the network’s reliability and make it possible to provide more customized services. This article provides an overview of 5G network slicing, discussing its layers and overall architecture. Additionally, the paper proposes a machine learning network slicing model based on feature selection, comprising three main components. Firstly, data collection involves gathering two different datasets from various sources. Secondly, feature selection algorithms are applied to choose the most relevant set of features, as the collected datasets may contain numerous unnecessary attributes and values. Lastly, various classification models are utilized on the selected features to predict the optimal network slice, thereby improving the efficiency of the 5G network. The analytical results and simulation models demonstrate that the proposed machine learning models with feature selection perform exceptionally well and accurately predict 5G network slices.

Dynamics Spectrum Sharing Environment Using Deep Learning Techniques

The recent fast expansion of mobile communication services has resulted in a scarcity of spectrum resources. The challenge of multidimensional resource allocation in cognitive radio systems is addressed in this work. Complicated and dynamic Spectrum Sharing SS systems might be vulnerable to a variety of possible security and privacy vulnerabilities, necessitating protection techniques that are adaptable, dependable, and scalable. Methods based on machine learning (ML) have repeatedly been proposed to overcome these challenges. We present a complete assessment of the current progress of ML-based SS approaches, the most crucial security challenges, and the accompanying protection mechanisms in this paper. We develop cutting-edge methodologies for improving the performance of SS communication systems in a variety of critical areas, such as ML-based cognitive radio networks (CRNs), ML-based database assisted SS networks, ML-based LTE-U networks, ML-based ambient backscatter networks, and other ML-based SS solutions. The results of the simulation trials show that the suggested strategy may successfully boost the user's incentive while reducing collisions. In terms of reward, the suggested strategy beats opportunistic multichannel ALOHA by around 10% and 30%, respectively, for the single SU and multi-SU scenarios.

Exclusion Clauses in Mobile Communications Industry

Exclusion clauses are contractual provisions commonly employed by mobile communications service providers to limit their liability and protect their interests. However, the extensive use of such clauses raises concerns regarding consumer rights and legal enforceability. This article presents an analysis of exclusion clauses in the mobile communications industry, aiming to shed light on their implications and consequences for consumers. By examining legal frameworks, industry practices, and relevant case studies, this study explores the enforceability of exclusion clauses, their impact on consumer protection, and potential legal challenges they may face. The paper highlights the need for a balanced approach that safeguards both the interests of service providers and the rights of consumers. By providing insights into this critical yet understudied aspect of mobile communications contracts, this article contributes to the broader discourse on fair contractual practices and encourages informed decision-making among policymakers, legal professionals, and consumers alike.

Differentiated Location Privacy Protection in Mobile Communication Services: A Survey from the Semantic Perception Perspective

Mobile communication services raise user privacy concerns in sharing the traveling trajectories while facilitating people’s daily lives. According to these shared trajectories, adversaries can dig users’ multi-modal behavioral semantics by combining with extensive open-source web information. These behavioral semantics have differentiated privacy sensitivity, raising different levels of privacy concerns. It makes users have personalized requirements for protecting their travelings. Resulting in the inevitable evolutionary trend from location privacy protection to differentiated location privacy protection (DLPP). DLPP digs into mobile semantics and characterizes the differentiated location sensitivity by simulating the potential attacks. It provides the privacy protection with differentiated strength to each location. Differentiated and appropriate strength well balances the tradeoff between privacy protection and data availability for the quality of application service. We are motivated to conduct a comprehensive survey on DLPP from the semantic perception perspective. It forms a complete overview of the mobile semantics-aware differentiation in location privacy protection. Specifically, we first review the research works on multi-modal mobile semantic representation. Then, taking the dug semantics as a clue, we summarize the basic principles of DLPP research systematically. To complete the overview, we also summarize their design modes and discuss the open opportunities and challenges for future works.

For Telework, Please Dial 7—Qualitative Study on the Impacts of Telework on the Well-Being of Contact Center Employees during the COVID19 Pandemic in Portugal

The COVID-19 pandemic has made teleworking a widespread form of work for contact center workers in Portugal, who are already used to work processes supported by technological platforms and digital workflows, but with little adherence to remote work. Deepening knowledge about the impact of teleworking on well-being at work is a relevant issue in the context of organizational literature. We conducted 14 semi-structured interviews with contact center workers who work in a large Portuguese company that provides fixed and mobile communication services, as well as customer service platforms. The interviews took place in April and May 2022. All participants had already carried out their functions in person and telework, and they were able to assess how telework added or took away their well-being at work. With the application of thematic analysis, seven themes (the basis for the title “For Telework, Please Dial 7”) emerged that characterize teleworking as being capable of reinforcing well-being at work: performance, relationship, money, workplace, technology, time, and family. These results contribute to the reinforcement of the growing literature on what contributes to increasing well-being at work, and alert leadership and organizational management are needed to properly configure telework to generate a positive dynamic that fulfils employees’ expectations and reinforces the organization’s sustainability.

Location-based on beam tracking method predicted using GP in UAV-supported systems

With the recent expansion of 5th generation mobile communication services, data demand is increasing. Correspondingly, the use of high-frequency millimeter waves and unmanned aerial vehicles (UAVs), which have features of high-altitude operation and mobility, and ease of deployment, is growing. However, for millimeter waves, narrow beams are used to compensate for large path losses, and appropriate beam allocation algorithms are essential. Therefore, in this paper, we propose an algorithm that utilizes a Gaussian process to predict the position of UAV-user equipment (UAV-UE). We then calculate the codebook based on the predicted position information and track the optimal beam in UAV-enabled communication systems. The results of a performance analysis confirm that the proposed algorithm can predict the UAV-UE position with high accuracy, and it has a high spectral efficiency. In addition, in the process of tracking the optimal beam, the complexity of codebook calculation is reduced by using the previously predicted UAV-UE position information.

ANALYSIS OF CHANGES IN THE NEEDS OF MOBILE COMMUNICATION CONSUMERS UNDER THE CONDITIONS OF MARITAL STATE

During the war in Ukraine, the need for means of communication and communication became unjustified (the ability to communicate with relatives, connect the emergency response service, etc.), therefore, there is a need to remove bottlenecks in the services of mobile operators, which manifested themselves by special characteristics. and equations of these manifestations in order to satisfy the primary needs of the population, actualized in the conditions of war, as much as possible. Today, difficult times have come to Ukraine: the war, and everything that it brings, destroys the life so familiar to many. With the loss of peace, the country’s population is no longer able to fulfill the levels of basic needs that Abraham Maslow wrote about: lack of a sense of security, loss of housing (permanent residence), power outages, and with it mobile communication. The study of the quality of received mobile communication services, changes in the needs of its consumers is important today, because the restructuring of needs requires modifications in the way they are met. Therefore, the main goal of mobile operators is to satisfy the primary needs of mobile users as best as possible, to support the spirit of the people by filling the “gaps” as best as possible. So, by conducting a survey this year and in 2021, we will be able to better understand the needs of mobile users today and try to find ways to meet them.
