Mobile network evolution: a revolution on the move

Abstract

This article gives an overview of the evolution in the mobile communications world. The uptake of 2G technologies has been tremendous, even though several systems exist that are not interoperable. 3G will bring some convergence, but will not achieve the goal of a single global technology. At the network level, IP is becoming more important. In hot spot environments, WLAN is bringing a complementary technology toward cellular.

Investigating the Impact of ICT Investments on Human Development

“…The global system for mobile communication (GSM) also accounts for over 66 percent of the world's total market (Vriendt, Laine, Lerouge, Xu & Alcatel, 2002), and the global diffusion of the internet (GDl) conducted across countries shows high levels of internet pervasiveness (Brown, Collins, Maleka, Morrison, Muganda & Speig, 2007). Internet is referred to as the linking together of two or more computers into global network of fibre optic cable, satellites and telephones for the purpose of information exchange (Morrow, 2002).…”

Hotspot wireless LANs to enhance the performance of 3G and beyond cellular networks

“…Presently, two approaches have been proposed for interconnection of WLAN and 3G networks: tight coupling and loose coupling [2]. A tight coupling scheme would offer seamless handover and the same level of security in WLAN and 3G networks.…”

“…In this case there will be a common customer and authentication procedure. Interworking between the WLAN and the core network will be performed between the authentication, authorization, and accounting server and the home location register [2].…”

“…Ultimately, beyond 3G networks will expand to offer data rates in excess of 100 Mb/s and interwork with a number of technologies including satellite communications, WLANs, and digital broadcast technologies. Eventually, such networks will provide integrated and seamless services via a common IP-based network [1,2].…”

Towards a Roadmap for Effective Handset Network Test Automation

“…In addition to supporting mobility, broadband networks also aims to support multimedia traffic, with quality of service (QoS) assurance. Therefore the evolution from 2G to 3G wireless technology bears the promise of offering a wide range of new multimedia services to mobile subscribers (De Vriendt et al, 2002). In this context, handset devices are following this ongoing network evolution and taking advantage of this technological update to offer a broad variety of resources and applications to their users.…”
