Combining with the working principle of Intelligent Transport System, and with the purpose of enhancing the security of modern traffic, this paper brings forward a project of building a kind of automobile emergent calling system which starts-up with the starting of airbag, the wireless date transport modem, which is droved by serial interface, transmitted the acquired data to the remote monitoring center. The design of the hardware circuit implement, the design of software and the design of building monitor and control center are demonstrated. ....etc

The General Packet Radio System (GPRS) is a new service that provides actual packet radio access for mobile Global System for Mobile Communications (GSM) and Time-Division Multiple Access (TDMA) users. The main benefits of GPRS are that it reserves radio resources only when there is data to send and it reduces reliance on traditional circuit-switched network elements. The increased functionality of GPRS will decrease the incremental cost to provide data services, an occurrence that will, in turn, increase the penetration of data s ....etc

This paper describes the rational behind the GRX in terms of worldwide access, security, reliability and scalability. It explores the structure of commercial, wide area, IP networks and the typical security and routing protocols employed within this environment. It is designed enable engineers who are working in this area to gain a firm understanding of the modern mobile packet switching architecture as well as a detailed insight into the requirement for, and operation of, the GRX. ....etc

ABSTRACT
The aim of this paper is to understand the architecture of the GPRS and focus primarily on the issue come up while migrating from existing GSM network to that of GPRS.The migration path from GSM to GPRS requires additional packet switching nodes, software upgrades in the base station subsystem. The existing GSM nodes to upgrade with GPRS functionally, command data service to provide for this GPRS operation need to deploy other elements access serves and firewalls
The general packet radio system is a new non-voice ....etc

A Technique for Orthogonal Frequency Division Multiplexing
Frequency Offset Correction

Abstract:
The Orthogonal Frequency Division Multiplexing (OFDM) is a Multi Carrier Modulation technique employing Frequency Division Multiplexing of orthogonal subcarriers. It is also sometimes called as discrete multitone modulation (DMT). It is better than CDMA in high bit rate and Broadband Communications .It is a multi carrier technique, which is very sensitive to Frequency Offset between transmitter and receiver. Th ....etc
