ALGORITHM OF BANDWIDTH DISTRIBUTION OF A LOGICAL CHANNEL OF A MULTI-SERVICE COMMUNICATION NETWORK, TAKING INTO ACCOUNT INSUFFICIENT OBSERVABILITY OF A RESOURCE PROVIDED BY A COMMUNICATION OPERATOR

В работе предложен алгоритм распределения полосы пропускания логического канала мультисервисной сети связи, позволяющий повысить качество обслуживания для отдельных сервисов в условиях, когда арендуемый у оператора связи ресурс пропускной способности характеризуется недостаточной наблюдаемостью и отсутствует обмен метками QoS на транспортном уровне. The paper proposes algorithm of bandwidth distribution of a logical channel of a multiservice communication network, which makes it possible to improve the quality of service for individual services in conditions when the bandwidth resource leased from a telecom operator is characterized by insufficient observability and there is no exchange of QoS tags at the transport level.

Inattention in Contract Markets: Evidence from a Consolidation of Options in Telecom

We study customer inattention by utilizing a notification about a future price change in the mobile subscription market. With detailed customer-level data from a large telecom operator, together with data on prices and contracts offered by competitors, we document that the notification causes an increase in customer attention, which triggers search, plan switching, and churn. In particular, we show that the monthly propensity to churn increases by 60% (from 1% to 1.6%) among customers whose costs would decrease with the new prices. We also document an increase in churn directly after the notification, not at the time of the future price change, and argue that this timing pattern is evidence of sophisticated inattention: customers take immediate action to mitigate the impact of their own future inertia. We supplement the analysis with a survey and find supporting evidence for the important role of inattention in determining how consumers adapt to changes in the market.

Internet of Things-Enabled Smart Entry System for Telecom Sites

Internet of things (IoT) is leading towards revolutionary applications with huge potential to improvise the efficiency multifold. IoT with the use of sensors has opened a huge window for applications in almost every area of life, and its penetration is endless with wireless connectivity. In this chapter, a wireless sensor-based solution for smart access control system for telecom sites is proposed and implemented. This project is initially implemented for 10 sites for a leading telecom operator, which will later on be scalable. This solution provides smart access to site engineers on the telecom site. Also, this system helps to remotely monitor multiple sites simultaneously, which protects the site from any forced entry and vandalism. The proposed solution and its implementation are given in detail in the chapter.

The use of anonymized and aggregated telecom mobility data by a public health agency during the COVID-19 pandemic: Learnings from both the operator and agency perspective

The COVID-19 pandemic and associated measures implemented have rapidly changed how people move about and behave in society. Utilizing data on people’s mobility could provide unique and valuable insights to governments and institutions to better manage the crisis. These entities, however, have not traditionally had access to, nor the experience of applying, continuous anonymized and aggregated data on people mobility. This article aims to show how the Public Health Agency in Sweden successfully collaborated with a Nordic Telecoms operator to make use of such data during the COVID-19 pandemic. Specifically, it investigates how the collaboration started, approaches used to go from data to insight, outcomes and impact, and lessons learned on both sides. Telia, the largest telecom operator in the Nordics, had an existing product commercially available that provided anonymized and aggregated insights about people’s movement. Several challenges existed within Telia as it was the first time worldwide a collaboration with a Public Health Agency would take place and social benefits had to be weighed against commercial and reputational risks. The hypothesis at the beginning of the pandemic was that the solution could be adapted to fit the needs of policymakers and the internal challenges could be overcome, while providing a meaningful contribution to the fight against the virus. The results show that it is possible to both form a mutually beneficial collaboration between a telecom operator and a public institution, and to make use of mobility data in evidence-based policymaking without compromising applicable personal data protection laws.

An investigation of brand equity dimensions and customer retention: A perspective of postpaid telecom subscribers in Lagos State, Nigeria

This study investigates brand equity dimensions and customer retention of the Nigerian telecommunications industry. Cross-sectional research design was adopted to survey 368 postpaid subscribers. The respondents were selected through multistage sampling techniques. The four dimensions of brand equity (brand awareness, brand association, perceived quality, and brand loyalty) were found to be correlated with one another and with overall brand equity. Similarly, the four dimensions were correlated to and significantly predicted customer retention. The study concluded that improvement of all the four dimensions of brand equity is indispensably vital to customer retention in the mobile telecom industry. The study recommended that telecom operator that is desirous of sustaining high brand notch in the marketplace should intensify their effort to improve on all the four dimensions of brand equity to enhance subscribers’ retention. Findings of this study fill important gaps and contribute to the body of literature related to brand equity dimensions and customer retention from customers’ perspective.

EXAMINING CUSTOMER SATISFACTION AMONG JIO TELECOMMUNICATION SERVICE USERS

India’s telecommunication network, by number of telephone users and internet user base, is the second largest in the world. There are different providers of cell phone services in our country and they play an important role in meeting the needs of customers. Jio has gained a significant market share and has accomplished numbers that look to attain competitiveness over a decade. It is the only network in India that is 4G only and its USP is the free services it provides. As part of its 4G offerings, Jio released a bundle of multimedia applications on Google Play in May 2016. While the apps are available for all to download, a user would need a Jio SIM card for them. A computer network or a data network is the digital telecommunication network that enables Reliance JIO Limited a subsidiary of Reliance Industry Limited to provide resources. Reliance JIO Limited is India’s largest private sector company, which is the first telecom operator to hold a unified licence for pan India. The business offers all communications services except satellite-serviced global mobile personal contact. This research includes examining consumer satisfaction with the Jio network and gathering data from 50 respondents with the aid of a convenient sampling technique. From its research, this study suggests improving network coverage and call connectivity.

AHP Method to Support Decision Making for Sustainability

In these challenging times, finding a way to sustain the created value becomes a must. The fierce competition, the risk of disruption, the rise of customer awareness and the scarcity of resources, all these are few of many drivers that push companies to invest in sustainability. This paper is an attempt to enrich the literature about this subject. It mainly explores how to use the AHP method, a well-known multicriteria decision making technique, to decide about the right actions to implement, in order to reach sustainability. The paper is a continuity of a previous work that introduced a new framework that explained how companies could sustain their business models through information systems (IS). This approach was applied on a telecom operator, as a case study, to explain well how companies could choose the right actions to implement, in order to reach sustainability.

The Hybrid Solar-RF Energy for Base Transceiver Stations

The base transceiver stations (BTS) are telecom infrastructures that facilitate wireless communication between the subscriber device and the telecom operator networks. They are deployed in suitable places having a lot of freely propagating ambient radio frequency (RF) and solar energies. This paper is aimed at converting received ambient environmental energy into usable electricity to power the stations. We proposed a hybrid energy harvesting system that can collect energy from RF and solar energies at the same time. The sources are combined to provide to a significant amount, to contribute to operational expenditures that reduce energy costs, and to improve the energy efficiency of the base station sites in rural areas from the most common renewable resources since the base stations are major consumers of cellular networks. The hybrid systems are designed with circuits, simulated, and compared to show their good performance to the base stations. PSIM, PROTEUS, and MATLAB software are used to simulate for evaluating the voltage and the current output of the hybrid systems that meet the power requirements. The design and simulation results show the feasibility of our proposed method with the battery storage that can be deployed not only in real base stations but also for other electrical operated systems.
