Digital economy in a global perspective: is there a digital divide?

This paper aims at analysing the state of the Digital Economy by observing growth patterns of some Developmental Variables (GDP and GDP Per capita) and some digitisation variables. We have analysed with the help of growth models, correlation and Granger Causality amongst Developing, Developed and the World Economy during a period of recent 15 years.There are five main findings. First, the existence of strong network economies between the broadband and the mobile technologies in developed world. Second, a general decline in fixed line services amongst all three-country grouping, which is not surprising. Third, economic growth variables and growth in mobile services are integrally linked. Fourth, there is bi-way causality between some growth variables and digitisation variables. Finally, there is evidence of a digital divide because digital economy at the global is dominated by developed economies, especially in E-commerce, which is a massive chunk of the global economy.

Performance Enhancement of Bit Error Rate with Increased Capacity using Modified SIC-MUD for Polar Code based OFDM-IDMA System for 5G

In the era of mobile data revolution there is a mass-market of smart phones culminating into an extensive growth in mobile services and applications. However, bandwidth is limited and valuable resource available. In this paper hybrid combination of OFDM-IDMA system is proposed using polar code as forward error correction code and Gold code based interleaver. It presents a method to improvebit error rate with 10 users and normalizedcarrier frequency offsets of 0.1 to 0.5.The simulation is done in the presence of Rayleigh and AWGN channel with 64 QAM modulation technique. A modified successive interference cancellation multi-user detection algorithm is proposed to cater multiple access interference.It is observed that proposed system withnormalized CFO of 0.1 for10 users at required SNR of 15 dB enhances the bit error rate to 1.021*10-4over available existing systems. Hence the capacity of the system and data rate increases by three times to support multimedia application within available bandwidth.

Impact of determinantsand social motivators on choice of mobile service operators in New Delhi

The technological advancement and reduced tariff have propelled the growth of mobile services in India. In the last ten years, the industry has made rapid growth in terms of subscriber base. Today, cell phones have become indispensable for people and moved beyond their fundamental role of communication. The Indian Mobile Service Provider (MSP) segment is overcrowded, customers have many choices of MSPs. nowadays, customers have become smarter and rational and consider various determinant factors before choosing an MSP. Hence, it is really important and beneficial for the marketers of MSPs to understand and analyze the choice making process of customers. As a result of its importance numerous determinants need to be considered when choosing mobile service provider. This study focused on determining factors and social influencers impacting consumer choice of mobile service provider. This study evaluated the significance of Connectivity/Geographical coverage, Service price, Promotion and customer handling. It, also, investigates the impact of social factors as a motivator pertaining to the choice of mobile service provider. The study was a sample survey of a cross section of mobile phone users. Data was collected with an adapted questionnaire distributed to 150 users using convenience sampling technique. The study found out that consumer decisions were impacted by determinants as Broad network coverage, Call quality, Service price, Brand penetration & offer schemes and Customer relationship. As a way of recommendation, it is important for a company to understand how customers define efficiency. The study recommends that in order to be competitively edged and to increase their market share, there is need to invest heavily in infrastructure and technological advancements that leads to improved coverage, reduce congestion,better call quality and have cheaper rates. Also, they should focus on customer as one important asset and brand image to be a leader.

The Relevance of Public Access Services and Universal Service Obligations and the Implications for Policy and Regulation – A Case Study of Innovative New Business Models to Address Public Access Services for Low Income Consumers

This paper explores the relevance of public access services and universal service obligations in light of the impact of increased competition in developing markets. A combination of factors is increasing mobile penetration in developing countries driven by the tremendous growth of mobile services in most developing countries reducing prices of telecoms services in general. Increased innovation has created low-cost handsets thus removing the barriers to entry for poor people. As a result of increasing penetration markets in urban areas and competition from multiple operators in the city centre, operators are extending their geographical reach and coverage. This has raised the question of the relevance of universal service obligations, which were initially created to expand access to areas which were perceived to have low commercial viability. A large portion of these obligations, included compelling operators to provide shared models of access in disadvantage areas. However, most such interventions have had limited success to date yet penetration is improving and access and usage of mobile services continue to grow. This paper will explore the relevance of universal service programmes in light of new market developments in emerging markets, using the South African example as a case study.

Changes and deregulation in the Japanese telecommunications market

The Japanese telecommunications market has experienced drastic changes since the privatization of NTT and the introduction of competition in 1985. Rate reduction in long distance services has been remarkable, and NTT's revenue share in the long distance market has declined sharply. The growth in mobile services and Internet services are epoch-making, and POTS is showing signs of decline. Behind the scenes is the progress of deregulation in remedying the distortion in the market structure. The establishment of new interconnection rules and the reorganization of NTT into one long distance company and two regional companies are the most important outcomes. With this deregulation the Japanese telecommunications industry is expected to develop from managed competition to full competition. However, new challenges for telecommunications regulation are emerging with the progress of competition and new multimedia services. One of them is the universal service. Cooperation among regulators, operators, users, and scholars is required to accommodate the change.
