Security in 2.5G Mobile Systems
نویسنده
چکیده
The global system for mobile communications, (GSM) is the most popular standard that implements second generation (2G) cellular systems. 2G systems combined with general packet radio services (GPRS) (3GPP TS 03.6, 2002) are often described as 2.5G, that is, a technology between the 2G and third generation (3G) of mobile systems. GPRS is a service that provides packet radio access for GSM users. The GPRS network architecture, which constitutes a migration step toward 3G sysAbstrAct

Impact of Prior Usage Experience on the Intention to Adopt 3G Mobile Service for the Youth in Hong Kong
Third generation (3G) mobile service has been launched for several years and yet the information systems (IS) community has not yet gained a full understanding of how various technological and social factors affect the intention to adopt this technology. This study probes into this issue using the Innovation Diffusion Theory (IDT) (Rogers, 1995) along with two other constructs, i.e., subjective...
متن کاملAn Architecture for Mobile Web Business Systems: Applied to the Healthcare Sector
Mobile business solutions are one of the most attractive products of mobile information services today. Furthermore, most current mobile businesses and mobile solution providers are contributing to the process of convergence. The existing mobile 2.5G (e.g. GPRS) networks combined with Internet-based services limit many current ideas and solutions. However, 2.5G mobile technologies can be a very...
متن کاملA New Intrusion Detection System to deal with Black Hole Attacks in Mobile Ad Hoc Networks
By extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. Security is a serious challenge for actual implementation in wireless networks. Due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attack...
متن کاملPolar Transmitter Pre-Distortion Technique Validated with 2.5G Mobile Communication Signals
This paper presents a polar transmitter predistortion technique validated with 2.5G mobile communication signals. The methodology used, [1], complements the drain bias modulation with a proper input drive level variation. This technique is believed to improve the linearity, while maintaining the efficiency of such transmitters, and it was validated in a real laboratory test setup.
