Abstract


The purpose of the research is to analyze the comparison of technology, network and security aspect between CDMA and GSM (Global System for Car communication). Using a comparative analysis research method between CDMA and GSM technologies that includes comparisons of network, technology, and security aspects. Using references from previous research on cellular telecommunications, the introduction of CDMA and GSM technologies to aspects of technology, networking and security. The results show that the technological aspect, CDMA used advanced spectrum technology that can provide superior sound quality and GSM uses a spectrum division technology that makes communication constant. From the network aspect, CDMA used direct-spreading spectrum (DS-CDMA) and GSM network is divided into three main systems: switching system (SS), base station system (BSS), and operating system and support (OSS). As well as security aspects, the GSM uses A3 and A8 algorithms for authentication and A5 algorithms were used in the process of sending information.But the security system using this algorithm, found weaknesses that allow data tapping or customer identity fraud. While CDMA offers aspects of network security by developing encryption algorithms.For encryption techniques used Rijndael algorithm is safe and very fast. A3 and A8 algorithms can recognize the customer's identity well, and the A5 algorithm can transmit the accuracy of information between MS and BTS.
