GSM Security
Mobile wireless networks are more vulnerable to unauthorised access and eavesdropping when compared with the traditional fixed wired networks due to the mobility of users, the transmission of signals through open-air and the requirement of low power consumption by a mobile user. This paper focuses on the security techniques used within the GSM standard. First, current GSM security system vulner...

متن کاملIntroduction to GSM and GSM Mobile RF Transceiver Derivation
This document provides an overview on the key measurements required for testing GSM transceivers. GSM mobile performance derivation is also discussed. This overview is intended to help a RF designer with no GSM RF system knowledge to get up to speed with the GSM system. Various systems are compared (GSM900, DCS1800, PCS1900, CT2, and DECT). Key design issues such as phase error and frequency er...
متن کاملAccurate GSM Indoor Localization
Accurate indoor localization has long been an objective of the ubiquitous computing research community, and numerous indoor localization solutions based on 802.11, Bluetooth, ultrasound and infrared technologies have been proposed. This paper presents the first accurate GSM indoor localization system that achieves median accuracy of 5 meters in large multi-floor buildings. The key idea that mak...
