Assessing the widespread deployment and increasing use of mobile services.

Mobile and wireless networks: services, evolution and issues

Wireless technologies in the last decade or so have attracted unprecedented attention from wireless service providers, developers, vendors, and users. The breathtaking evolution of wireless technologies, services and business applications has resulted in a wide-scale deployment and usage of wireless and mobile networks. The paper discusses mobile and wireless networks in terms of services, technical evolution, and related issues. Industries such as transportation and logistics, financial services, health services, and many others should be able to improve their performance by implementing wireless mobile technologies.

WIRELESS EVOLUTION 2006: CELLULAR TV, WEARABLE COMPUTING, AND RFID

This paper summarizes the panel discussion at AMCIS 2006 on the evolution and trends in mobile wireless services and technology. The panelists included information systems faculty members from the United States and Mexico. The covered topics included wireless fundamentals, wireless technologies, applications and value chain evolution, wearable computing, wireless mobile issues including privacy and security, issues of worldwide mobile services and trends, and social implications. The panelists believe that there has been a virtual explosion in the ubiquitous and embedded computing industry over the past decade. Computing technology is moving beyond personal computers and is progressing into devices with embedded technology. The trend of mobile wireless technologies is moving to one single device rather than multiple devices. A single device could contain any or all of the following components, such as cellular phone, digital camera, video recording, MP3, mobile cellular TV services including digital multimedia broadcasting (DMB) and digital video broadcasting, handheld (DVB-H). Also, wearable computing such as watches, smart shirt and clothing, body sensors, and health monitoring devices are in the nascent stages. Wireless technology known as radio frequency identification (RFID) is used to identify objects, including living creatures. Various RFID applications including item tagging and electronic passports prompted valid loss of privacy concerns and triggered intense and sometimes irrational public discussion.

Social Networking and Social Media in the United States, South Korea, and China

This article summarizes the panel discussion at Americas Conference on Information Systems (AMCIS) 2012 on the social media environment around the world, particularly the United States, South Korea, and China. The panelists discussed the current status of social networking and social media in the aforementioned countries. The first section begins with United States, with social networking pertaining to the population at large, the use of social networks in the business environment, and observed overuse and addictive behavior of wireless mobile devices (WMD) among users. The second section covers South Korea, with the discussion addressing social networking sites (SNS) and its history; the collectivism of Asian culture and how it affects users’ behavior toward SNS; current trends, which include privacy concerns; and the future direction of SNS in Korea. Finally, in China, social media is further explored in the business models of SNS providers, followed by the customer base comparison between the United States and China.

Competition and strategic dilemmas in the telecommunications industry: making the triple play

Southern Bell Corporation, now AT&T, decided to upgrade its existing networks by extending its optical fiber network only to the neighborhood nodes and use existing telephone twisted pair copper wires to connect nodes with households. Leaders of Verizon Communications, on the other hand, decided to extend their optical fiber network all the way to homes at much higher cost. The choice of which of the two approaches was a better business decision is the main dilemma in the case. The network upgrades were necessary to keep telecommunication operators competitive with cable television companies, which after they upgraded their networks started offering the ‘triple play,’ a combination of video programming, telephone, and Internet services. The case reviews the history of telecommunication and cable industries in the United States, which leads to exploration of the key issues including (i) whether, and if so how competition in the telecommunication industry is even possible, (ii) how much bandwidth do we really need, and (iii) what is the effect of various compression techniques, convergence of digital technologies, and what other countries are doing. The case (describing the state of the industry at about the start of 2011) addresses an issue affecting all of us as we decide what services to select for our entertainment and communication needs.
