Introduction:
In this 21st century we required a multi functional system to operate on different platforms, which can access data easily, the main purpose of a Heterogeneous server is to establish a Heterogeneous network that can connect computers and other devices with different operating systems and/or protocols. For example, local area networks (LANs) that connect Microsoft Windows and Linux based personal computers with Apple Macintosh computers are heterogeneous. The word heterogeneous network is also used in ....etc

LATEST SMART CARD FEATURES

Latest Features of Smart Cards and Intelligent Tokens

Abstract
Smart Cards are plastic credit cards devices with an integrated circuit
chip with microprocessor. These smarts cards have the mechanism for
storing and/or processing
information. Intelligent Tokens (iButton) are high capacity general-
purpose electronic data carriers, each with a unique registration
number. They have the same components as
smart cards but are shielded by a steel case. This paper will show t ....etc

Introduction to cdma2000 Standards for Spread
Spectrum Systems


OVERVIEW

The cdma2000 Family of Standards
The cdma2000 family of standards includes core air interface, minimum performance, and
service standards (see 1.3). The cdma2000 air interface standards specify a spread
spectrum radio interface that uses Code Division Multiple Access (CDMA) technology to
meet the requirements for Third Generation (3G) wireless communication systems. The
core air interface standards in the family are [ ....etc

CDMA2000 is a technology for the development of cdmaOne/IS-95 to 3rd generation services. Also known as IMT-CDMA Multi-Carrier or IS-2000 is the main route for CDMA operators to second-and-a-half ( 2.5G) and third generation (3G) cellular networks. A set of new standards that define the new air interface and the Radio Access and Core Network changes that will enhance network capacity, improve speed and bandwidth to mobile terminals, and allow end-to-end IP services has been created by the standard-setting body behind CDMA2000 known as 3GPP2.
