The Future of Mobile Industry
This paper discusses the future of mobile industry along with some of the background
leading to the emergence of wireless technology. First, it gives an overview of todayâs
telecommunication network and the major differences between fixed wired networks and
wireless networks. The discussion then focuses on the challenges facing the wireless
industry and the way out through aggressive innovation by employing Wireless Intelligence
Network (WIN) technology. The paper also discusses some important trends in wireless
industry and the customers expectations which are also part of the challenges for the
mobile industry. Finally particular reference is made to the developing nations especially
Nigeria in the ongoing trends in mobile communication industry
Mobile Phone:The Past,The Present and The Future
Since the introduction of cellular analogue phone in 1985 (first generation mobile phone),
there has been a continuous improvement from the first generation to digital secondgeneration
to 2.5 generation and now the third-generation. The ground is also being
prepared for the fourth-generation mobile phone. Mobile technology has transformed our
lives in ways that might have seemed unimaginable some years ago and yet we are still
witnessing more transformations and many more are yet to come. This paper examines the
concept of cellular communication, the development of mobile phones, the features in the
past, the current trends and what to the future holds in general and specifically for Nigeria.
The cost implications of the various generations over the previous ones to the end users are
also discusse
The MobyDick Project: A Mobile Heterogeneous All-IP Architecture
Proceedings of Advanced Technologies, Applications and Market Strategies for 3G (ATAMS 2001). Cracow, Poland: 17-20 June, 2001.This paper presents the current stage of an IP-based architecture for heterogeneous environments, covering UMTS-like W-CDMA wireless access technology, wireless and wired LANs, that is being developed under the aegis of the IST Moby Dick project. This architecture treats all transmission capabilities as basic physical and data-link layers, and attempts to replace all higher-level tasks by IP-based strategies.
The proposed architecture incorporates aspects of mobile-IPv6, fast handover, AAA-control, and Quality of Service. The architecture allows for an optimised control on the radio link layer resources. The Moby dick architecture is currently under refinement for implementation on field trials. The services planned for trials are data transfer and voice-over-IP.Publicad

Health and mobility: Current status and future paradigms
The movement of telemedicine to the wireless and mobile Internetable applications is imminent in the next few years. This migration from the desktop platforms to the wireless and mobile configurations will have significant impact on the future health care delivery system and their globalisation. The recent telecommunications and biomedical computing advances will significantly enhance the current methodologies of telemedicine and telecare systems. This editorial will present some of the evolutionary issues and important aspects that have to be considered in the developing technologies for the next generation of Internet and Third Generation of Mobile Systems (3G), geared for future telemedical applications. These will provide new dimensions to existing medical services and areas of outreach, that are not possible in the current generation and will have tremendous impact on how the health care delivery will be shaped for the 21 Century
A review of personal communications services
This article can be accessed from the link below - Copyright @ 2009 Nova Science Publishers, LtdPCS is an acronym for Personal Communications Service. PCS has two layers of
meaning. At the low layer, from the technical perspective, PCS is a 2G mobile
communication technology operating at the 1900 MHz frequency range. At the upper
layer, PCS is often used as an umbrella term that includes various wireless access and
personal mobility services with the ultimate goal of enabling users to freely communicate
with anyone at anytime and anywhere according to their demand. Ubiquitous PCS can be implemented by integrating the wireless and wireline systems on the basis of intelligent network (IN), which provides network functions of terminal and personal mobility. In this chapter, we focus on various aspects of PCS except location management. First we describe the motivation and technological evolution for personal communications. Then we introduce three key issues related to PCS: spectrum allocation, mobility, and standardization efforts. Since PCS involves several different communication
technologies, we introduce its heterogeneous and distributed system architecture. IN is
also described in detail because it plays a critical role in the development of PCS. Finally, we introduce the application of PCS and its deployment status since the mid-term of 1990âs.This work was supported in part by the National Natural Science Foundation of China

Communication Standards Adoption in Developing Economies: Issues and Options for India
Given the importance of communications in todays world, its spread in developing economies is critical for their development. Emergence of standards reduces market and technological uncertainty and lays the foundation for market creation and enhances the diffusion of communication technologies partly through the advantages associated with network and scale economies. Standardisation has also become important with the rise in cross-fertilisation between information technology (IT) and other technologies, especially in communications. Under these circumstances, strategic implications of IT standardisation are huge because standards can determine the growth potential of individual firms, affect the competitive advantage of nations and even development of technologies and their diffusion. Policies for standards adoption have been used world-wide to facilitate the diffusion of communications technologies, acquire a larger market share of the global telecom market, build technological capabilities. The paper reviews various approaches to communications standard adoption as well as the experiences of other countries. These approaches and experiences and the associated market and regulatory failures are evaluated in the context of the current Indian situation. This evaluation suggests that a standards neutral policy is desirable for India.
