ABSTRACT
Cellular Digital Packet Data (CDPD) is a specification for supporting wireless access to the internet and other public data networks. CDPD transmits digital packet data at 19.2 Kbps, using idle times between cellular voice calls on the cellular telephone network. CDPD technology represent a way for law enforcement agencies to improve how they manage their communications and information system.

CDPD TECHNOLOGY



INTRODUCTION

Mobile Computing: A technology that allows transmission of data, via a computer, without having to be connected to a fixed physical link.

Principle of Mobile Computing: The ability to send and receive data across the cellular networks.

First Generation

Analog Signal Communication
Advanced Mobile Phone System (AMPS) by North America
Based on Frequency Division Multiple Access (FDMA)
1664 Channels were available.
832 downlink an ....etc

CDPD is a secure, proven, and reliable protocol that has been used for several years by law enforcement, public safety, and mobile professionals to securely access critical, private information. CDPD has several features to enhance the security of the mobile end user's data and these are discussed below.

OPERATION OF CDPD

A brief overview of the operation of the CDPD network is as follows:
A wireless modem (or Mobile End System-M-ES) communicates by radio with the Mobile Data Base Station (MDBS). The MDBS transfers this data by landline ....etc

Cellular Digital Packet Data

Abstract :

Cellular Digital Packet Data is a technique, which is applicable over cellular network for quick transfer of data. It is applicable in providing a quick transfer of data over cellular networks. It transmits the packets over the cellular network in a reliable manner. Packet networks break a stream of data in to independent blocks of data called the packets. CDPD is wirelesses IP network that overlay on the existing AMPS cellular infrastructure. The CDPD raw channel modulation user rate is 19.2 kbps. ....etc
